As you may already have observed, in a lot of manufacturing plants, hoists are often used to move heavy items from A to B, as well as to help in loading finished materials onto lorries for delivery.
More than a few hoist parts are commonly overlooked, with only the hook and chain being easy to observe.
Not Quite as Simple as You Imagined
A number of the practically hidden hoist parts are:
- The chain spool
- The chain roller guide
- The drive gears which engage the spool and release or retract the chain.
- Top quality Brindley Chains are more popular nowadays than ever.
Other important parts that assist in helping to control the lifting ability of the hoist are that of:
- The control panel housing all of the hoist’s control buttons
- The drive motor that can change between an electric motor to an air-powered one.
Concealed Parts and Other Components
There are also hidden hoist parts, such as:
- The drive motor
- Lift hooks
- Lifting arm lever locks
All are often overlooked with just a quick glance.
Some other very important hoist parts such as:
- The safety catch
- The control lever
- Mounting bolts are crucial to the operation and use of the hoist
Cables, and chain slings, plus roller guides and control switches are important and relevant components to any hoist.
An air-powered hoist makes use of an air compressor, air hose and line filter to avoid any kind of harm being done to the motor’s inner workings, from exposure to water from the airlines.
With the electric-powered hoist type, several hoist parts are found in the electrical system of the structure.
- Fuses and wiring harnesses which are essential to delivering the power to the motor are fitted inside walls to remain out of sight.
Water filters which extract most of the trapped water from the airlines are crucial to the long lasting and smooth working of a hoist. One proactive component fitted in the airline of a hoist motor is something known as an oil injection unit.
- This a very fine mist of oil into the airline at pre-set periods of time so as to help in the lubrication of the hoist motor.
Some other proactive elements of a hoist are the safety emergency cable/chain locks that are made to put a stop to any accidental dropping of loads from an elevated height.
Excess Weight and Flashing Lights
There’s also a spool clutch which has been designed to slip if a load is too heavy for the hoists lifting ability, and is also typically incorporated into the hoist design.
Bright flashing lights and a beeper warning sound are hoist parts which are commonly found on a hoist to alert workers when a hoist is moving overhead so that they must be careful and aware of any safety concerns pertaining to the movement of the hoist.
And you thought it was just some humble chain slings and a hook!
