V-belt used for? V-belts are belts with a trapezoidal cross-section. Like other types of belts, they are used to transmit power or torque from the driving component to the driven component. V-belts get their name from their trapezoidal shape, which helps them wedge into the sheaves. Twisted synthetic fibrous tensile chords, compressed by synthetic rubber form a typical V-belt, rendering it strength and flexibility. A v-belt is a flexible machine element used that transmits power between a set of grooved pulleys or sheaves. They are characterized by their trapezium cross-section. V-belts are used because of their ability to wedge tightly into the grooves of the pulley.

The lead oarsman grumbled, “Only eighty six of copper cash? We would have had so much more if Minami had not been along! Pity that the Sea Lion is his boat and he won't let us use it unless he is along.”

While he was counting out the crew's shares, Magistrate Lim asked sympathetically, “Narutsu san, what exactly transpired out there on the water to say such a thing of Minami san?”

They all assumed the proper kneeling of persons before the Tribunal and lead oarsman Narutsu explained, “Good Magistrate Lim, recently he forced iron works of his own making on all the fleet.

“For two years past, we had iron works so good that never did a rope jam or anything work less than perfectly. As the owner, we could not prevent him from doing so for his own boat, the Sea Lion. By the threat of refusing their catch, he made the other boats do so as well.

“None of his iron work functions well at all, and those are the good times. Ratchets do not hold properly on winches, letting line go when it should not, or worse, the whole winch will freeze up and it and time is wasted making it work. Net guides fail to turn, making it difficult to pull in the fish. The pulling block on the crane, needful to lifting the heavy loads of nets with fish, not only froze, the rope slipped off of a pulley sheave and jammed firmly when it was most needed.

“We were working to get the rope loose and back on the sheave when Minami struck it on the side with the iron end of a long boat hook. The force of his strike caused a sharp edge to break the rope in two and completely broke the whole pulling block.

“The slowness of pulling the net in by hand in a tangled heap because the take up roller's pawls would not hold let most of the school get away.

“Worse, he blamed the whole debacle on Dee san and her friends, though it was obvious to us all that it was wholly his fault and no other's.”

Magistrate Lim thoughtfully stroked his neat beard and mustaches for a moment. “Are you aware, good oarsmen, that Minami san owes you all a substantial sum of money? For the last two of years he has been taking in all the catch of every boat that went out on a day without even weighing it. He then paid you all for only the fish that he sold, but not for those that his poor management of the Fish Market allowed to spoil.

“He owes you money for all of the fish that spoiled, nearly a third of the catch. The Tribunal has records of the money that he earned, and how much was lost. We have divided up his arrears by the number of boats out for each fishing day. Due to his poor record keeping, that is the best that we can do.

“Given that, he owes the group of you a total of,” he pauses to consult a sheet in Miko's neat calligraphy, “two of golden cash, of silver cash, one string and twenty two, of copper cash, three strings and nineteen.”

The crew sat in stunned silence. Finally lead oarsman Narutsu, shaking his head in disbelief, asked “Good Magistrate, how can we recover this money? It is our understanding that he has nothing.”

Bowing politely to them, Magistrate Lim replied, “Not quite so, Narutsu san. He has still the Sea Lion. His house, land and the ice house, are joint properties that cannot be seized.

“You have three avenues open to you. First, you may take a lein on the Sea Lion, giving you ownership until his debit is paid from shares of catch. He must have one tenth of the proper share. This will take a few years to pay off.

“Second, you may simply seize the Sea Lion, and write off the balance of the debit. Doing so will give you the boat as it is now and a loss on paper of about one cash of gold, of silver cash, one string. That loss can reduce your Tribute tax for up to three years. Miko san can give you precise details.

“Thirdly, you can continue as you are now, receiving a share of the arrears each time that he makes a payment to the Tribunal on his debit.”

The crew put their heads together, conferring on what to do.

At the Fish Market, a smiling Tanira watched as the girls working for her neatly put the display fish in an ice chest and covered all of the trays with thick blankets.

She offered, “Minara san, Takahara san, thanks to your good help, I have not only had a good day of sales, your backing me up down on the dock was invaluable.” She handed them hand tied strings with six copper cash each. “I did not miscount. Frankly, you girls are worth more to me than this but with all of the problems connected to this, it is all that I can afford.”

The girls bowed, “Thank you so much, Tanira san. Why don't you and young Ichuru come with us and share our evening meal with the Shop of Repairs gang? No charge, of course.”

Young Ichuru san was amazed and delighted by the meal that was brought in to a long table in the Chiasu warehouse. Not only was the food plentiful and tasty, all of the young ladies there treated him with the proper respect due to a grown up!

His mother was also somewhat goggle eyed, but for a different reason. “My word, Dee san, that is a big boat that you are making, isn't it?”

Dee bowed her pleasure as she replied, “It is indeed, Tanira san. It is a full twenty two paces long by nearly six wide. Beam, I think that the width is called.”

“That is amazing, Dee san! It will be the largest boat in Sabo when you are done with it! Even as wealthy as I know that you are, how can you afford so much fine, flawless lumber? But aren't those planks that I see stacked there awfully thin? A hand span wide but only about as thick as a chopstick? How?”

Patsu looked up from the big fish filet that she was tucking into and grinned, “It is dirt cheap, Tanira san! You won't believe this, but those planks are bamboo!”

She waited for that bombshell to go off in Tanira's mind before adding, “We found something in an oldish fold book from Chin. It told us how to make wood soft so that fun things can be done to it. We took it a step further and turn bamboo into bamgoo! By products of making bamgoo give us both a lot of fiber and the glue that we use on all of our boats now, as well as being able to form those thin planks.”

One of the other girls at the table, seeing that Patsu was being free with info but holding back the bamgoo process, chimed in, “We know that those planks are thin, Tanira san, but when we are finished there will be five layers of them. That will be very strong.”

Dinner over, one of the girls gave Ichuru san a toy boat as long as arms. It was made of the same thin bamgoo planks as the big boat that they were building.

As they emerged into the street, they were met by Minami, who was in the company of Constable Canra.

As he was starting to demand, “Where is my din . . .” the Constable tapped him gently with his cudgel.

Reminding him with soft words he stated, “Do not become unruly, Minami san, or I shall take you before Magistrate Lim.”

Minami glared at the Constable but went on, “Where is my dinner, woman? You have been dining with the enemies of all goodness and forgotten your husband.”

Not raising her voice but her anger plain, Tanira retorted, “Your dinner is in the same place that your manners have gone, you foolish man! Buy it out of your catch shares until you learn that courtesy which costs nothing will buy you much!”

“Do you know what those men of mine have done?” He waived a paper at her, snapping, “They have placed a lein on my Sea Lion! They took all but ten percent of my share as a payment on it!”

She nodded, with a shrug, “So, how much did you get?”

He angrily cast two copper cash at her feet! “That is all for a whole day's work!”

Ichuru gathered up the coins and offered them back, “Father sanma, these are yours.”

Phantom Friday, coming aboard edition.

F-4 Phantom II about to trap on CV-63 USS KITTY HAWK, but look closely... something is different.

Aircraft carriers customarily have 4 arresting cables at the back of the ship to trap landing aircraft, Here, one is missing. Visible are #1 wire, #2 wire and #4 wire, bit the preferred #3 wire isn't there. That actually is not that uncommon.

Under the flight deck are four arresting gear engines...

... assemblies of sheaves, pulleys, hydraulic cylinders and brakes designed to absorb the energy of a landing aircraft and bringing it to a stop. One for each wire. Like any complex machine, sometimes things break, but flight operations have to continue. In that case the cross-deck pendant (as the wire is called) connected to the broken engine is removed and aircraft continue landing using the other three. The optical landing system or "meatball" is re-calibrated for a slightly steeper approach and the #2 wire becomes the target. When the engine is fixed the wire is replaced and operations continue uninterrupted.

What is an Elevator? Knowing the Basics and Types of Elevators

Elevators have become part and parcel of modern architecture and urban life, now making it quite easy to move from one floor of a building to another. But what exactly is an elevator? In short, an elevator is a means of vertical transportation for people or goods between floors in a building. We will discuss basic information on definition, types, components, and what technology is behind those insistent systems that daily we take for granted in this blog. Understanding the Basics of an Elevator An elevator is defined as an elevator is a platform or a compartment that accommodates persons or cargo housed in a vertical shaft in the form of lifting or lowering individuals or cargo from one floor to another. The idea of the elevator started during ancient civilization using a simple pulley system to heave materials and people. However, in terms of modern technologies and design, there is a great improvement from the traditional era.

How Elevators Work Modern elevators make use of both mechanical and electrical components. In general, they are more commonly powered through an electric motor that can help turn a set of pulleys and cables. Here's a breakdown on how a typical elevator works

Control system When you activate your floor request, say by pressing the button on it, the control system registers your request and acts to activate the elevator. Motor and Pulleys This motor converts power into rotation of a sheave, a term used to refer to a pulley that moves the cables that the car is attached to. In some designs, this elevator is given a counterweight that balances the load in place and makes the movement even more efficient. Safety Mechanisms The whole aspect of safety does not come to mind when one talks about elevators. However, modern elevators today are incorporated with numerous safety mechanisms, such as an emergency braking system, sensitive door sensors, and backup power, among many others. Types of Elevators There are many kinds of elevators, each suitable to the purpose served and the environment it is to be put into. Among some of the most well-known types are: Traction Elevators This is one of the most widely used types in tall buildings. They use ropes, along with a counterweight system, to move the elevator car up and down. Traction elevators are highly efficient and fast. Hydraulic Elevators Typically found in low-rise buildings, hydraulic elevators use a fluid-driven piston to move the car. They are less expensive to install but are limited in height and speed compared to traction elevators.

Pneumatic Elevators possibly unique, using air pressure to push the car. Pneumatic elevators are used more frequently in residential areas and can, in many ways, be an iconic addition to a home. Freight Elevators They are used mainly for the movement of cargoes and thus large and robust. Their usage is often seen in the warehouse and industrial premises. Glass Elevators These are glass elevators with plenty of scenic view as it travels from floor to floor. They are usually traction elevators but with very striking designs. The Importance of Elevators The most important parts of present-day infrastructure. Indeed, especially in the city, once-thin skyscrapers now stand with much taller and more complicated structures as if to touch heaven. It has ensured that everything could be reached, because everybody can travel multi-level buildings safely and conveniently, especially those who are less able or elderly, while others are liberated for commercial purposes through speedy movement of goods and service.

Elevator Safety Standards Elevator safety is among the primary concerns in designing and utilizing elevators. The installation and maintenance of elevators are subject to a wide range of regulations and standards. Some of the other standards include:

Regular inspections

Emergency protocols

Load limits

Fire safety measures

The Future of Elevators The future of elevators is promising as the technology is on the move. For instance, smart elevators have lately used artificial intelligence to improve their performance and energy consumption. These systems may predict the traffic and make cases decrease waiting times, which means energy efficiency leading to greener buildings. Another thing is that there are elevators that can be designed to travel not only vertically but also horizontally. This will promote more dynamic building design and urban planning.

Conclusion In summary, an elevator is more than just a convenient mode of transportation between floors. It is a complex system that combines engineering, technology, and safety measures to provide efficient vertical mobility in our buildings. From traction and hydraulic systems to innovative designs like pneumatic and glass elevators, the diversity of options caters to various needs and settings.

The Top 5 Manitowoc Crane Parts to Inspect for Signs of Wear

In the demanding world of heavy lifting and construction, Manitowoc cranes stand out for their reliability and performance. However, even these robust machines require regular inspection and maintenance to ensure safe and efficient operation.

This article focuses on the top five Manitowoc crane parts that demand particular attention when checking for signs of wear. By understanding these critical components, crane operators and maintenance teams can prevent costly downtime and potential safety hazards.

1. Wire Ropes and Cables

Wire ropes and cables are the workhorses of Manitowoc cranes, responsible for lifting and moving heavy loads. These components endure significant stress during normal operations, making them prone to wear and tear. When inspecting wire ropes and cables, look for broken wires or strands, kinks, corrosion, flattened sections, or any reduction in rope diameter.

A reputable crane parts supplier will emphasize that even minor damage can compromise the integrity of these critical components. Industry standards dictate that wire ropes should be replaced if they show signs of more than 5% wire breakage within a single lay length. Regular inspection of these Manitowoc crane parts is not just a recommendation—it's a necessity for maintaining operational safety and efficiency.

2. Hydraulic Hoses and Fittings

The hydraulic system is the lifeblood of Manitowoc cranes, powering various functions from boom movement to outrigger deployment. Hydraulic hoses and fittings, constantly under pressure, can develop weak points over time. During inspections, pay close attention to any signs of cracks or blisters in the hose material, leaks around fittings, kinked sections, or excessive swelling.

The importance of these checks cannot be overstated. A study by the Fluid Power Safety Institute found that nearly 25% of hydraulic accidents are due to hose failures. This statistic underscores the critical nature of regular inspections and timely replacement of worn Manitowoc crane parts, particularly in the hydraulic system.

3. Sheaves and Pulleys

Sheaves and pulleys play a vital role in the smooth operation of a crane's lifting mechanism. These Manitowoc crane parts guide the wire ropes and distribute the load evenly. When inspecting sheaves and pulleys, focus on identifying any cracks or chips in the sheave groove, uneven wear patterns, excessive play in bearings, or misalignment of sheaves.

Crane maintenance experts advise that sheaves should be replaced when the groove wear exceeds 1/32 inch or 3% of the rope diameter, whichever is less. Worn sheaves can accelerate wire rope degradation and affect lifting precision, making their regular inspection a key aspect of crane maintenance.

4. Slewing Ring and Bearings

The slewing ring allows the crane's upper works to rotate smoothly, making it critical for precise load positioning and overall crane stability. When examining this large bearing, listen for unusual noises during rotation and watch for excessive play or movement. Uneven rotation or jerky movement can also indicate wear, as can the presence of metal particles in the lubricant.

Elevators: Taking You Up and Down, Explained

An elevator, also known as a lift in some regions, is a vertical transportation system that moves people or goods between floors in a building. It's an essential component of modern structures, allowing us to navigate high-rise buildings efficiently and safely. But have you ever wondered how these marvels of engineering actually work? Let's delve into the mechanics behind a smooth elevator ride.

The Two Main Elevator Systems:

There are two primary mechanisms that power elevators: traction and hydraulic.

Traction Elevators (Most Common):

Engineered for Height: These are the workhorses of high-rise buildings.

Motor Power: An electric motor is the heart of a traction elevator. It's connected to a sheave, a large grooved pulley.

Lifted by Cables: Strong steel cables are looped around the sheave and attached to the elevator car on one end and a counterweight on the other.

Up and Down: When the motor turns one way, it rotates the sheave, causing the cables to move and raise the elevator car. Reversing the motor direction lowers the car.

Balancing Act: The counterweight, typically weighing as much as the car plus some additional load, helps balance the system and reduces the energy needed to move the elevator.

Hydraulic Elevators (Better for Low-Rise):

Limited Height: These elevators are more suitable for buildings with fewer floors due to the limitations of hydraulic systems.

Powered by Pressure: A hydraulic elevator uses a piston and cylinder system filled with hydraulic oil.

Lifting Force: An electric pump pressurizes the oil in the cylinder, forcing the piston upwards and lifting the elevator car. Releasing the pressure allows the car to descend.

Brains Behind the Brawn - The Control System:

Modern elevators are equipped with sophisticated control systems that manage every aspect of the ride. These systems include:

Floor Selection: Passengers use buttons or touchscreens to select their desired floor.

Dispatch System: This system determines the most efficient way to serve all waiting passengers, minimizing wait times.

Safety Features: Elevators are equipped with multiple safety mechanisms, including door sensors, overload protection, and overspeed governors that halt the car in case of emergencies.

Beyond the Basics:

While these two systems cover the core functionality, additional features can enhance elevator performance:

Variable Frequency Drives (VFDs): These electronic devices regulate the motor's speed, resulting in smoother starts, stops, and improved energy efficiency.

Gearless Drives: Some traction machines use gearless motors directly connected to the sheave, offering quieter operation and improved efficiency.

Conclusion:

The next time you step into an elevator, take a moment to appreciate the ingenious mechanisms at work. From the powerful motors and cables in traction systems to the pressurized oil in hydraulic elevators, these marvels of engineering transport us safely and efficiently every day. Whether you call it an elevator or a lift, understanding how they work adds a layer of appreciation for this ubiquitous invention.

Everything to Know About V-Belt: Types and Construction

The V-belts transmit power between parts of machines efficiently. Often, they are used on car engines for accessories such as air conditioner compressors, power steering pumps, alternators, and fans. The v-belt is a belt with a trapezoidal section and can be classified according to its dimensions. This blog discusses the main uses, construction features, and types of v belts.

What is a V-belt?

The V-belt transmits energy from one shaft into another. The cross-section of a v-belt is trapezoidal. A wedge-shaped belt will fit perfectly in the grooves of a pulley. V-belts are more powerful than flat belts because of this perfect fit. Pulley systems using v-belts have their pulleys close together. In the case of belt tension, the vertical forces that are perpendicular to the V-blet push its wall against the grooves of the sheave as the forces maximize the belt wedges into the sheave groove, which increases the friction between the belt surface and walls. The various frictional force V belt drive to transit higher loads.

Features of the V-Belt Construction

The V Belt Specification:

Steel Wires: The steel wires are endless and have no joints in between them. The wires are used to reinforce the belt and provide strength.

Rubber compound as the base: The rubber compound is the inner core that surrounds the steel wire to give the belt its shape. Rubber compound (elastic) is also used as a compression medium to absorb shocks when transmitting power.

Cover: This is the protective layer that protects the rubber from the heat generated by the belt movement.

Based on Their Dimensions, V-belts Are Classified Into Different Types.

The belt fabric supplier offers fabrics for V-belts of different sizes and types. The basic shape of each type is the trapezoidal, but they have different sizes.

V Belt Types :

Standard V-Belt: Also known as the classical or conventional V belt, this is one of the oldest forms. These types of belt drive the transmission of energy between machinery parts.

Wedge V-Belt: The conveyor belt manufacturers primarily design this belt for power transmission and space-saving. The load capacity of these belts is 1.5-2 times greater than that of a classical V-belt with the same width. The cord placement and construction are improved, resulting in the strongest belts while they're moving.

Narrow V Belt: These belts look similar to wedge-shaped belts. These belts are used to transmit larger loads but in a more compact form.

Double or Hexagonal V-Belt: These V belt types are similar to two mirror-imaged V-belts, with the top side as their adjoining sides. The tension cord goes between the V-shaped section. The double v-belt is used in drives that have one or more reverse bends. This is because the belt can be bent on either side of the compression core.

Cogged V-Belts: These belts are V-shaped and have a notch at the bottom. This allows them to bend with smaller radiuses. The belt fabric manufacturers offer fabrics for belts in a variety of cross-sectional dimensions, including standard, narrow wedge, banded, and fractional horsepower V-belts.

V-Belt Advantages

There is a very small amount of slippage between the belt and the pulley.

The V belts are usually used for the pulley system as they offer quiet operation.

The small space between pulley centers allows for a compact structure.

A v-belt pulley system dampens vibration. The V-grooves provide a good grip, allowing for the transfer of power.

V-Belt Applications

The Most Common Application of V Belt Drive Include:

Drills

Power Tools

Agri machines

Milling Machines for Light Duty

Conclusion:

V-belts are flexible machine elements that transfer power from one set of pulleys to another. The trapezium-shaped cross section is what makes them unique. They are chosen because they can fit tightly in the grooves on the pulley. The belts reduce slippage and loss of power by breaking up the friction on surfaces with a higher coefficient.

What is an Elevator? Knowing the Basics and Types of Elevators

Elevators have become part and parcel of modern architecture and urban life, now making it quite easy to move from one floor of a building to another. But what exactly is an elevator? In short, an elevator is a means of vertical transportation for people or goods between floors in a building. We will discuss basic information on definition, types, components, and what technology is behind those insistent systems that daily we take for granted in this blog. Understanding the Basics of an Elevator An elevator is defined as an elevator is a platform or a compartment that accommodates persons or cargo housed in a vertical shaft in the form of lifting or lowering individuals or cargo from one floor to another. The idea of the elevator started during ancient civilization using a simple pulley system to heave materials and people. However, in terms of modern technologies and design, there is a great improvement from the traditional era.

How Elevators Work Modern elevators make use of both mechanical and electrical components. In general, they are more commonly powered through an electric motor that can help turn a set of pulleys and cables. Here's a breakdown on how a typical elevator works

Control system When you activate your floor request, say by pressing the button on it, the control system registers your request and acts to activate the elevator. Motor and Pulleys This motor converts power into rotation of a sheave, a term used to refer to a pulley that moves the cables that the car is attached to. In some designs, this elevator is given a counterweight that balances the load in place and makes the movement even more efficient. Safety Mechanisms The whole aspect of safety does not come to mind when one talks about elevators. However, modern elevators today are incorporated with numerous safety mechanisms, such as an emergency braking system, sensitive door sensors, and backup power, among many others. Types of Elevators There are many kinds of elevators, each suitable to the purpose served and the environment it is to be put into. Among some of the most well-known types are: Traction Elevators  This is one of the most widely used types in tall buildings. They use ropes, along with a counterweight system, to move the elevator car up and down. Traction elevators are highly efficient and fast. Hydraulic Elevators Typically found in low-rise buildings, hydraulic elevators use a fluid-driven piston to move the car. They are less expensive to install but are limited in height and speed compared to traction elevators.

Pneumatic Elevators possibly unique, using air pressure to push the car. Pneumatic elevators are used more frequently in residential areas and can, in many ways, be an iconic addition to a home. Freight Elevators They are used mainly for the movement of cargoes and thus large and robust. Their usage is often seen in the warehouse and industrial premises. Glass Elevators These are glass elevators with plenty of scenic view as it travels from floor to floor. They are usually traction elevators but with very striking designs. The Importance of Elevators The most important parts of present-day infrastructure. Indeed, especially in the city, once-thin skyscrapers now stand with much taller and more complicated structures as if to touch heaven. It has ensured that everything could be reached, because everybody can travel multi-level buildings safely and conveniently, especially those who are less able or elderly, while others are liberated for commercial purposes through speedy movement of goods and service.
