How Do You Use A Chain Hoist? How to Use a Chain Hoist
Attach a connection hook to hold the hoist mechanism to the support system.
Move the chain hoist directly below the connection hook and lift up by the hook on top of it.
Place the load being hoisted under the chain hoist and straighten it out as much as possible.

What is chain hoist? A Chain Block (also known as a hand chain hoist) is a mechanism used to lift and lower heavy loads using a chain. 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.

How Do You Use A Chain Hoist? – Related Questions
Can I use a chain hoist to pull horizontally?
(Hand) chain hoists, typically, can only be used vertically. If they are used to move the load horizontally, the chain will get jammed and gears inside can be damaged to shorten the lifespan.
How do you loosen a dropped chain?
To lift the load, pull the hand chain (15) to rotate the handwheel in clockwise direction. When pulling the hand chain in the reverse direction, the handwheel will be separated from brake seat (10), the ratchet disc (14) checked by pawl (17) will be released, and the load will be lowered down smoothly.

What is the difference between a chain fall and a come along?
Chain hoists lift weights when the operator/operating device pulls a chain and is used for lifting loads vertically. A come along, or lever hoist lifts through the use of a lever and can lift or move objects and loads horizontally as well as vertically.
How many types of chain blocks are there?
There are two different chains in chain block which are load chain and hand chain. Load chain lifts or lower the loads when the hand chain is pulled.
How does a coffing hoist work?
Coffing hoist is the trade name of a well-known group of chain-operated hoists.
When the loop is shortened, the hook block and load is lifted, achieved by having one end of the loop fixed to a static point within the hoist casing while the other end is attached to a driven take-up spool.
What is a lever chain hoist?
A Lever Hoist is a piece of high-quality equipment used to lift and lower heavy loads without the aid of machinery.
Lever Hoists have the ability to lift items in most positions, including horizontally.
What is the mechanical advantage of a chain hoist?
Chain hoists were developed from the older type of wire or rope cable pulley configuration. In such a configuration, fixed pulleys allow cool direction to be changed. Movable pulleys and compound pulleys produce force multiplication, or a mechanical advantage, of at least 100 percent or more.
Can you back hook a chain block?
Wrapping the main chain and back hooking is sometimes used instead of slings, but this stops the hook swivelling, which means any twists in the chain are not removed.
Note: Back hooking is not permitted by the original equipment manufacturers (OEMs) of come- alongs.
What are some examples of different types of hoists?
There are three main types of manual hoists, including:
Hand Chain Hoists.
Lever Hoists or Ratchet Hoists.
Lineman’s Hoist.
Electric Chain Hoists.
Electric Wire Rope Hoists.
Air Chain Hoists.
Air Wire Rope Hoists.

Are chain hoists safe?
Do Not use hoist with twisted, kinked, damaged, or worn wire rope or chain. Do Not lift a load unless wire rope is properly seated in its groove(s) or unless chain is properly seated in chain wheel(s) or sprocket(s). Do Not use load rope or load chain as a sling or wrap load rope or load chain around the load.
How does a chain fall stop the load from falling?
At the end of the lifting chain is a grab hook, which allows to easily attach and detach a load. Also, most chain hoist lifting mechanisms have a ratchet or braking system that prevents the load from slipping back, but allows to lower a load by pulling the other side of the hand chain.
What is an advantage of the screw jack over the ratchet jack?
An advantage of jackscrews over some other types of jack is that they are self-locking, which means when the rotational force on the screw is removed, it will remain motionless where it was left and will not rotate backwards, regardless of how much load it is supporting.
