What is the purpose of hoists?
A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
What is the difference between a hoist and crane?
The main one is their range of movement. Hoists can only move loads up and down, while cranes can move loads up and down and side to side. In the latter, a hoist serves as the component that provides vertical movement, while a trolley and bridge serve as the components that enable horizontal movement.
How do gantries work?
They consist of a bridge that moves along the tracks, as well as a hoist or a winch moving along the crane bridge structure. Gantry, or “portal”, cranes allow efficient and effective close transport within a construction site or industrial plant by moving loads vertically and horizontally.Dec 17, 2019
What is headroom on a hoist?
Headroom is the space from the point on the hook where the load will be hanging to the point where the hoist, or hoist and trolley, connects with the support member the hoist hangs from. This can often be an I-beam such as a horizontal building support or some kind of crane such as a jib crane or gantry crane.
What is crane lifting height?
In its simplest definition, lift height is the distance from the floor to the saddle of the hook, when the hook is in its uppermost position. Lift height is a vital measurement in any project because it assures there is enough room to lift or lift and reposition the load you are lifting.Feb 25, 2020
What is crane hook height?
What is Hook Height or Height of Lift? The hook height the required dimensions from the crane hook to the floor when the crane hook is at its lowest position. This is the measurement that determines how high the runway is from the floor and it is relevant to the clear interior height of the building.

How do you calculate chain blocks?
The thumb rule you should follow here is this – measure the height of the lift. Make sure that the load chain length is equal to the lifting height and hand chain is almost two feet less than the lift length. For example, if the length of the lift chain block is 20 feet, then that of the hand chain should be 18 feet.
