Hoists & Winches

Hoists and winches are machines that lift, lower or pull loads using a chain, wire rope or synthetic rope wound on a drum or passed over a sprocket. A hoist is designed mainly for lifting, usually hanging from a hook, a beam trolley or the structure of a crane. A winch is a drum mechanism that winds in or pays out rope, used for pulling loads horizontally or up slopes and, in suitable versions, for lifting. The two terms overlap, and many manufacturers offer both.

These machines are among the most widespread lifting devices in construction and industry. A manual chain hoist can lift a pump into position in a plant room, an electric wire rope hoist forms the lifting unit of an overhead crane, and a large winch can pull cables, move heavy structures or lift loads on a gantry. Hoists and winches are also the heart of many other machines: cranes, piling rigs, construction hoists and recovery vehicles all rely on winches to move their loads.

Brief History of Hoists and Winches

Winches and windlasses were used in ancient times to raise water, lift building stones and haul ships, often driven by people or animals through cranks, treadwheels and capstans. Pulley blocks multiplied the force available and remained essential tools for builders for centuries.

The industrial age brought steam-powered winches, iron chains and wire ropes, which greatly increased capacities. The differential chain block and later the worm-geared and spur-geared chain hoists of the nineteenth century gave workers a compact manual device for lifting heavy loads. Electric motors in the late nineteenth and early twentieth centuries led to the electric wire rope and chain hoists used in factories, workshops and overhead cranes. Hand-operated rope pulling devices, such as the Tirfor from Tractel, offered portable pulling and lifting with a continuous wire rope. In recent decades, hoists and winches have gained frequency-controlled drives, overload protection, radio controls, load monitoring and synthetic ropes.

How Hoists and Winches Work

Power source. Manual (hand chain, lever or crank), electric, pneumatic (compressed air) or hydraulic. The power source determines speed, duty and where the machine can be used.
Gearbox. Reduces motor or hand speed and multiplies force, so a small input can lift a heavy load.
Drum or sprocket. Wire rope and synthetic rope are wound on a drum. Chain passes over a pocketed load sprocket and falls into a container or hangs free.
Brake. A load brake holds the load when the hoist stops. Electric hoists typically use a spring-applied, electrically released brake, while manual hoists use a mechanical load brake.
Reeving. Passing the rope or chain through several falls with pulley blocks increases capacity and reduces speed.
Suspension. Hoists hang from a hook, a lug or a trolley running on a beam. Winches are usually base-mounted or fixed to a frame or vehicle.
Controls and protection. Pendant or radio controls, limit switches for upper and lower hook positions and overload devices are standard on powered hoists.

Types of Hoists and Winches

Manual Chain Hoists

Hand-operated hoists in which the operator pulls a hand chain to raise or lower the load through a gearbox. They are compact, need no power supply and are widely used for installation and maintenance work.

Lever Hoists

Also called ratchet or come-along hoists, operated with a lever. They can lift, pull and tension loads in any direction and are common for positioning, tensioning and securing.

Electric Chain Hoists

Powered hoists using a load chain, often with a trolley on a beam. They suit workshops, assembly and many site applications with moderate capacities.

Electric Wire Rope Hoists

Heavier-duty hoists with a rope drum, used as the lifting unit in overhead cranes, gantries and heavy industrial applications. They offer higher capacities, lifting heights and speeds.

Air and Hydraulic Hoists

Pneumatic hoists are used where electric equipment is unsuitable, such as in explosive atmospheres, and in heavy-duty continuous operation. Hydraulic hoists and winches are common on mobile machines and vessels.

Pulling Winches

Drum winches and capstans used for pulling cables, dragging loads, tensioning and recovery. Cable pulling winches are widely used for power lines, underground cables and pipes.

Lifting Winches

Winches designed and certified for lifting, with suitable brakes and safety devices. They are used on cranes, gantries, hoisting frames and construction material lifts. Winches used to lift people require specific design and approval.

Rope Grip Devices

Machines such as the Tirfor that pull a wire rope through gripping jaws, allowing unlimited rope length and use in any direction.

Capacity Classes

Class	Typical capacity	Typical equipment
Light	up to about 1 t	Manual and electric chain hoists, small winches
Medium	about 1 to 10 t	Chain and wire rope hoists, lever hoists, pulling winches
Heavy	about 10 to 50 t	Wire rope hoists, heavy manual hoists, large winches
Very heavy	above about 50 t	Special wire rope hoists and winches for cranes and heavy lift

Choosing and Using Hoists and Winches

Separate lifting from pulling. A pulling winch is not automatically suitable for lifting. Use equipment designed, rated and marked for the task.
Match the duty. Check the duty classification for the number of lifts, running time and load spectrum. A hoist used continuously in production needs a higher class than one used occasionally.
Check the anchorage. Beams, lifting points and anchors must be rated for the load plus dynamic effects. The hoist is only as safe as the point it hangs from.
Choose the right power source. Manual units suit occasional work and places without power. Electric, air or hydraulic units suit repeated or heavy lifting.
Consider speed and control. Two-speed or variable-speed drives allow precise positioning of delicate loads.
Keep the rope or chain in good condition. Worn, kinked, corroded or damaged chain and rope must be replaced, and only the manufacturer’s specified chain or rope should be used.

Safety

Hoists and winches must be used within their rated capacity, by trained people, with lifting operations planned and supervised in line with local regulations. Before use, operators should check hooks, safety latches, chain or rope, brakes, limit switches and controls. Loads must never be carried over people, and nobody should stand under a suspended load. Side pulling with a hoist, using the hook tip, and wrapping a chain around a load are common causes of accidents. Winch ropes under tension store energy and can whip violently if they fail, so exclusion zones are needed along the rope line. Periodic thorough examination by a competent person is required in most countries, and in Europe powered winches and hoists are covered by standards such as the EN 14492 series.

Trends and Technology

Powered hoists increasingly include variable-frequency drives for smooth movement, radio remote controls and digital displays of load and operating data. Condition monitoring records the number of lifts, load spectrum and remaining service life, supporting planned maintenance. Synthetic ropes, lighter than steel, are spreading in winches for pulling and recovery. Battery-powered portable hoists and winches are appearing for site use where no mains supply is available, and connectivity allows fleet owners to track usage and inspection status.

Key Terms

Rated capacity (WLL): the maximum load the hoist or winch is designed to lift or pull in normal service.
Falls: the number of rope or chain parts supporting the load block.
Load brake: the brake that holds the load when the hoist is stopped.
Duty class: a rating of how intensively a hoist can be used.
Capstan: a rotating drum that pulls rope wrapped around it by friction, without storing the rope.
Come-along: an informal name for a lever hoist or hand-operated pulling device.

Frequently Asked Questions

What is the difference between a hoist and a winch? A hoist is designed mainly to lift loads vertically and usually hangs above the load. A winch winds rope on a drum and is mainly used for pulling, although lifting winches exist.

Can a pulling winch be used for lifting? Only if it is designed, rated and marked for lifting. Many pulling winches lack the brakes and safety factors needed for suspended loads.

Chain hoist or wire rope hoist? Chain hoists are compact and suit lighter loads and shorter lifts. Wire rope hoists suit heavier loads, greater lifting heights and higher speeds.

How often must hoists be inspected? Operators should check them before each use, and a competent person must carry out periodic thorough examinations at intervals set by national rules and the manufacturer.
