Hoists, Slings and Material Handling Gear

Hoist, winch or sling: which one matches the lift

A hoist lifts a load vertically and holds it, a winch pulls it along a line, and slings, shackles and hooks connect the load to either. The two are not interchangeable: many winches are rated only for pulling and may lack the brake needed to hold a suspended load. Chain hoists come hand-operated or powered, and compact models differ from industrial ones in duty rating. Furniture lifters and conveying parts such as guiders belong to separate, specific jobs.

Capacity, lift height and parts that must match the hoist

Capacity is quoted in pounds, kilograms or tons, and it applies to the whole assembly: the hoist, its chain, the hook and anything below the hook all need a rating at or above the load. Lift height decides chain length, so allow for the distance from the hook to the load as well as the travel. Rated capacity is a working limit, never a target to reach.

Many listings are replacement parts for a named hoist: brake side plate assemblies, load chain and guiders carry the hoist model and capacity in the title, and they fit only that range. A part rated 3/4 ton will not suit a 3 ton unit, and a cut or worn load chain should be replaced rather than repaired. Overhead lifting gear is also subject to periodic inspection under workplace safety rules.

Questions about Hoists, Slings and Material Handling Gear

Can I use a winch to lift a load overhead?

Only if the winch is explicitly rated for lifting. Most are designed for pulling and may not hold a suspended load safely if power or the brake fails. For overhead lifts use a hoist rated for the load, and never stand beneath a raised load.

What is a below-the-hook accessory?

It is any device between the hoist hook and the load, such as slings, shackles, hooks, spreader bars, beam clamps and lifting magnets. Each has its own rated capacity, and the lowest rating in the chain sets the limit for the lift.

How do I choose the right capacity?

Weigh or calculate the heaviest load, add the weight of the rigging and slings, and choose a hoist rated well above it. Angled slings carry more force than the load weight, so check the sling's rating at the angle you will actually use.
