Hi, I would like to know the real/original name of the 'chain hoist/pulley' I was taught 50 years ago when of doing O levels physics. I guess it was the inventor's name. Obviously we can still buy them but they only call them a chain hoist or pulley. thks john 23.11.10
A chain check stopper is a device used to prevent excessive overtravel of a chain in a chain hoist or overhead lifting system. It is designed to securely stop the chain from moving past a certain point, providing a safety feature to protect against potential accidents or damage.
If a hoist stopped working during a transfer, the first step is to ensure the safety of the individual being transferred. Assess the situation to determine if it can be resolved by checking power sources, controls, or any obstructions. If the issue cannot be fixed immediately, have a backup plan in place such as using a manual transfer technique or calling for assistance. Regular maintenance and checks on the hoist can help prevent such situations from occurring.
False. General requirements do apply to slings used with other material handling equipment for the movement of materials by hoist. These requirements ensure safety and proper usage, regardless of the equipment involved. It is important to follow established guidelines to prevent accidents and ensure safe lifting practices.
25 ============================================================ 1 ton is 2000 pounds , so 1/2 ton is 1000 pounds ( 20 bags ) x 50 pounds = 1000 pounds ( 20 bags at 50 pounds each would be the MAXIMUM lifting capacity of a 1/2 ton hoist ) * the first answer is not mine , the 2nd answer is , Helpfull
A derrick is a drilling, crane-type machine used in on-shore oil drilling operations. The derrick is a large metal tower made out of a pattern of metal tubing called lattice. In the center of the machine is a trolley that can carry whatever tool used for mining. For drilling into the ground the tool is obviously a drill that is dropped from that top of the tower for more force. After the oil drilling is completed the tower is used as the oil spout. If you've ever been to Butte, Montana you'd see these large towers all over the town.
A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.
Rope and pulley.
Hoist means to raise or lift something up, typically using a pulley or mechanical device.
A lever chain hoist works by using a lever to lift heavy loads. As the operator pulls the lever down, it engages a ratcheting mechanism that lifts the load. The chain attached to the hoist is used to support and lower the load.

A chain is only as strong as it's weakest link.
Not unless there's a pulley involved.
old english
A pulley doesn't raise or hoist sails. A pulley is just a wheel that eases a change in direction of a rope. It is a rope that hoists or raises sails. A rope for this purpose is called a Halyard.
Electric chain hoists use an electric motor to power a chain mechanism that lifts and lowers heavy loads. When the motor is activated, it drives the chain to lift the load, and when the motor is reversed, the load is lowered. These hoists are commonly used in industrial settings for their efficiency and precision in handling heavy materials.
This is referrred to as exercising a simple machine called a pulley.
