Air hoists: chain vs wire rope explained

An air hoist lifts a load straight up and down at a fixed point, and unlike an air winch, which pulls along a line on a drum, a hoist is built for vertical lifting. But within hoists there is a basic choice of how the load is lifted: on a load chain or on a wire rope wound on a drum. The two look and behave differently, and they suit different lifts, so choosing between a chain and a rope air hoist is part of matching the hoist to the work, much as choosing between a winch and a hoist is, the subject of our note on the air winch versus air hoist.

How a chain hoist lifts

A chain hoist lifts the load on a load chain that runs over a toothed wheel, with the slack chain collecting in a bag or container below. It is mechanically simple and very compact, packing a useful lift into a small, light unit, and the chain does not need a large drum. Its lift height is limited by how much chain the hoist can handle and store, and it tends to lift more slowly than a rope hoist. For shorter, simpler vertical lifts in a confined space, where compactness and simplicity matter more than height or speed, the chain hoist is a neat, robust choice.

How a rope hoist lifts

A rope hoist lifts the load on a wire rope wound onto a drum, much like a winch but arranged for vertical lifting. The drum can hold a long rope, so a rope hoist can lift to a much greater height than a chain hoist, and it tends to lift faster. The trade is that the drum makes the hoist larger and less compact than a chain unit of similar capacity. For longer lifts, where a load must be raised a long way, or where speed matters, the rope hoist is the better design, giving the height and the pace that a chain hoist cannot.

Lift height: the clearest difference

The most practical difference between the two is how far they can lift. A chain hoist is limited by the chain it can run and store in its bag, so its lift height is modest, while a rope hoist holds a long rope on its drum and can lift much higher, bounded by the drum capacity rather than a chain bag. So the first question is usually how high the load must be raised: a short lift suits a chain hoist, a long lift needs a rope hoist. This single factor often decides the choice before the others come into play, because a hoist that cannot reach the height is simply unsuitable whatever its other merits.

Speed and compactness

Beyond height, the two differ in speed and size. A rope hoist generally lifts faster, which matters where the load must be raised quickly or often, while a chain hoist is slower but very compact, fitting into tight spaces and light enough to rig easily. So a duty that needs a quick lift points to a rope hoist, while one in a confined space where a small, simple unit is wanted points to a chain hoist. These qualities, speed against compactness, often decide between the two once the lift height has been settled, balancing how fast against how small the hoist needs to be.

Why both are air driven

Whether chain or rope, an air hoist shares the reasons for being air driven, and they are the same as for air winches. The air motor does not spark and runs cool, so the hoist is safe in flammable, ATEX rated areas, the subject of our note on ATEX air winches. It tolerates wet and dust, can be stalled holding a load without harm, and is controlled simply by feathering the air. These qualities make air hoists, like air winches, the natural choice for wet, dusty and hazardous lifting, so the choice between chain and rope is about the lift, not the power source, which they share.

The air supply both need

A chain or rope air hoist performs only with the right air supply, exactly as an air winch does. It needs enough flow at the correct pressure for its rated lift, supplied clean, dry and lightly lubricated through a filter, regulator and lubricator, as our note on air winch lubrication and FRL covers. Starve it of air and the hoist lifts slowly and weakly; feed it wet or dirty air and the motor wears. So the air supply is part of specifying the hoist, and on the wet sites where air hoists often work, keeping water out of the air matters as much as the choice of chain or rope.

Matching the hoist to the lift

Choosing between a chain and a rope air hoist follows the lift. A short, simple vertical lift in a confined space, where compactness and simplicity matter, suits a chain hoist; a long or fast lift, where height and speed matter, suits a rope hoist. The load, the height, the speed and the space are weighed together, along with the hazard of the area and the air available. The honest approach is to describe the real lift first, then choose the hoist that fits it, rather than starting with a preference, which we are glad to help with as part of specifying air lifting equipment for the job. A few jobs sit on the boundary, a moderate height at a moderate speed, and there the space and the budget often tip the choice, with the chain hoist winning on compactness and the rope hoist on reach.

Choosing the right air hoist with us

We supply air hoists in chain and rope designs to suit the lift, alongside air winches for pulling. See the range in our winch catalogue, read our overview of pneumatic winches and how a hoist differs from an air winch. Tell us the load, the lift height, the speed, the space and the air you have, and we will point you to a chain or rope air hoist that fits the lift rather than the nearest size.

Frequently asked questions

What is the difference between a chain and a rope air hoist?

A chain hoist lifts on a load chain over a toothed wheel and is very compact, suited to shorter, slower lifts. A rope hoist lifts on a wire rope wound on a drum, can lift much higher and faster, but is larger. The lift height, speed and space decide which fits.

Which lifts higher, chain or rope?

A rope hoist. It holds a long rope on its drum and can lift much higher than a chain hoist, whose height is limited by the chain it can run and store in its bag. So a long lift usually needs a rope hoist, while a short lift suits a chain hoist.

Which is more compact?

A chain hoist. It packs a useful lift into a small, light unit without a large drum, so it fits tight spaces and is easy to rig. A rope hoist needs a drum to hold its rope, making it larger, which is the trade for its greater height and speed.

Why are these hoists air driven?

For the same reasons as air winches: the air motor does not spark and runs cool, so it is safe in flammable, ATEX rated areas, tolerates wet and dust, and can hold a stall. This makes air hoists the natural choice for wet, dusty and hazardous lifting, so the choice between chain and rope is about the lift, not the power.
