What Does Hoisting Mean In Construction?
Hoisting is the act of raising, lowering, or otherwise moving a load in the air with equipment covered by this standard. Hoists are machines specifically designed to raise and lower loads that are too heavy for manpower alone.
They have a drum or wheel around which wraps either a chain or rope that controls whether the load is raised or lowered.
Hoists can be manually operated, electrically or pneumatically driven, and may be used for lifting or lowering a freely suspended (unguided) load. In construction, hoists are often used to move materials up and down between floors.
When performing hoisting and rigging operations, it is important to consider safe working practices such as following the manufacturer’s recommendations for the hoist being used, using proper hand signals during lifting operations, and ensuring that the safety latch helps prevent the release of the load.
What Is The Difference Between Lifting And Hoisting?
The main difference between lifting and hoisting is that hoisting involves suspending an object, person, or materials using a pulley system while lifting involves raising an object in a controlled and guided manner.
Hoists use ropes, chains, or braided wires connected to a pulley system to raise and lower the load. Examples of hoisting include raising a flag or transporting heavy loads from different floors and decks.
On the other hand, lifts are tools used to transfer materials and workers to an elevated part of a building or construction site. Examples of lifting include using a forklift truck or screw jack to lift objects in a controlled manner.
What Is An Example Of Hoisting Equipment?
An example of hoisting equipment is a crane, which is a type of machine equipped with a hoist rope, wire ropes or chains, and sheaves that can be used to lift and lower materials and move them horizontally.
Other examples of hoisting apparatus include mobile cranes; tower cranes; electric overhead traveling cranes; vehicle hoists; winches; jacks; lever-operated hoists; and hinged jibs. Hoists are powered by either an electric motor, pneumatic motor, or manual gear system.
They are used in conjunction with overhead cranes and workstation cranes to lift freely suspended heavy loads. Hoisting equipment is used in a variety of industries including construction, manufacturing plants, and material handling.
What Are The 3 Types Of Hoists?
There are three main types of hoists used in care environments: ceiling hoists, stationary hoists, and gantry hoists. Ceiling hoists are highly sophisticated, permanent fixtures that are installed overhead with a track system.
Stationary hoists are simple models that can be suspended or mounted in stationary locations by being hooked or bolted onto permanent fixtures or movable stands.
Gantry hoists are mobile hoists that can be used for two purposes – to help move patients with minimal discomfort and risk of injury, and to lift cargo, construction materials, and other items.
Additionally, there are powered hoists that come in three varieties – electric, air/pneumatic, and hydraulic.
What Are The 3 Main Areas You Must Check Before Using A Hoist?
Before using a hoist, there are three main areas to check: service label and date, the functionality of the hoist unit, and the condition of the pendant housing, buttons, and cables.
The service label should be checked to ensure that the hoist has been serviced in the last 6 months.
The hoist unit should be tested for movement by using it as if it were lifting a service user. The pendant housing, buttons, and cables should be inspected for any signs of damage or wear.
Additionally, all installed hoist and travel limit switches should be checked for failure by raising and lowering throughout the full range of the lifting mechanism.
