Chain Pulley Hoist

Chain Pulley Hoist: Whether you have to lift, pull, position, tension, or rig a load, you must have the right manual hoist for the job.

Chain pulley hoist is excellent for general purpose lifting and pulling applications. Popular with the homeowner and outdoorsman, they are also preferred by professionals who work in tough applications such as construction and mining.

Manual and lever chain pulley hoist come in a variety of model families, each with a set of features that allow you to choose the right hoist for the job, and at the right price. Each hoist is designed to meet ASME/ANSI specifications and is enhanced to make them as user-friendly as possible.

For example, the ergonomic design of the handgrips on lever hoists and the overload protection on manual hoists add comfort and safety for operators.

During Hoist Operation:

  • Maintain a secure footing to prevent slipping and injury while operating.
  • Confirm that the hoist unit is attached securely to support before the operation.
  • Verify hook latches are not supporting any of the load.
  • Do not hold the chain pulley hoist during hoist operation.
  • Slowly take up the load, verifying it is well supported and balanced before proceeding.

Hand Chain Hoist Operation

Attaching the Load

  • If there are no twists in the chain proceed on to attach the lower hook to the load.
  • Do not use the chain pulley hoist to wrap around the load.
  • The load should be seated in the bowl of the hook and should not bear against the tip of the hook or latch.
  • The hook latch should be tightly closed against the hook tip
  • Assure that the upper and lower hooks form a straight line and frame is able to swivel.

Lifting the Load

  • Pull chain clockwise.

Lowering the Load

  • Pull chain counterclockwise

Chain hoist how it works

A hoist is a device that is used to lift or lower the load attached to it by the means of a lift wheel or drum. The lifting of the load is done by the rope or wire that is looped around the wheel or the drum. The wheel or the drum may use electricity for its operation or in some cases it may also be manually operated. Along with the drum and the wire, another integral part of the hoist is the lifting medium that is used.

  • The different lifting mediums that are used are a chain, fiber orwire rope.
  • A hook is also available where the load is attached.
  • One of the most commonly used types of hoist worldwide is Chain Hoist.
  • The type that is commonly used is electrically operated.
  • In this type of hoist, the chain pulley hoist is used as the lifting medium.
  • Here there is a closed chain that forms a loop which ultimately lifts the load.
  • A pulley is also attached to the hoist to lift the load.
  • Numerous small and large pulleys are found in the chain pulley hoist.
  • For raising the load, the chain has to be pulled.

When pulled, the large pulley draws in more chain than what is required by the smaller side facilitating the beginning of the lifting procedure.

Areas of application of chain hoist

The different areas of application of chain hoist comprise of industries mostly manufacturing ones and construction sites.

The working of the chain pulley hoist can be understood from the following points:

  • It uses gears to multiply the force.
  • A chain pulley hoist, when operated by hand, requires an operator to pull the light loop chain on the side.
  • This turns a gear mechanism inside 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 pulley hoist.
  • The mechanical work done by the operator is the same as the work done by the heavy lifting chain

The procedure specified can also be automated by using the electrically operated Chain pulley Hoist. Thus it simplifies a lot of load-lifting work.

How chain pulley block works?

What is a Chain Block?

A Chain Block (also known as a hand chain pulley hoist) is a mechanism used to lift and lower heavy loads using a chain. Chain blocks contain two wheels in which the chain is wound around. When the chain is pulled, it winds around the wheels and begins to lift the item that is attached to the rope or chain via a hook. Chain Blocks can also be attached to lifting slings or chain bags to lift the load more evenly.

How Does a Chain Block Work?

A Chain Block contains a lifting chain, a hand chain, and a grabbing hook. Most chain blocks are operated using electricity, but manual chain blocks can be used too. First, the chain block needs to be connected to the load via the grabbing hook. Then when the hand chain is pulled, the chain tightens its grip on the wheel and forms a loop inside the mechanism causing a tension that lifts the load from the ground.

What is a Chain Block used for?

Due to its lifting capabilities, Chain Blocks are commonly used in garages where they are able to remove engines from cars easily. Because they can be operated by one person, Chain Blocks are a wonderfully efficient way to complete jobs that may have taken more than two workers to do.

Where does a Chain Block use?

Chain Blocks are also used on construction sites where they can lift loads from the higher levels, in assembly-line factories to lift items to and from the belt and sometimes even to winch cars from treacherous terrain.

What is the capacity of a chain pulley hoist?

Chain Blocks come in a variety of different capacities making them suitable for a wide range of operations of up to 20 tonnes.
