How to choose an electric hoist in 5 steps

Quick answer: Choose an electric hoist in 5 steps: capacity (heaviest load plus tool, with a 20–25% margin), power supply (single-phase 220 V for 60–480 kg, three-phase 380 V for up to 20 tons and continuous duty), speed control (two-speed, variable frequency or servo), support structure (rail, jib crane or gantry) and working environment. For millimeter positioning choose a servo hoist that runs as slow as 0.05 m/min; for clean rooms or explosion-risk areas use a clean room hoist with a bellows-covered chain or an air hoist.

What an electric hoist is and when a factory needs one

An electric hoist uses an electric motor to drive a load chain or wire rope, and it hangs from an overhead rail, a jib crane or a gantry crane. A plant needs one when loads heavier than about 25 kg are lifted many times per shift: molds, CNC workpieces, motors, drums, material rolls or crates.

A wrong choice usually shows up in three ways: the rated capacity is too close to the real load and the hoist wears out early, the speed is too fast so the load jerks and is hard to place on a fixture, or the hoist does not match the power supply on the shop floor. Below are the five steps the FullSharp engineering team uses during a site survey.

Steps 1 and 2: capacity and power supply

Capacity is the heaviest load plus the weight of the tool (hook, gripper or vacuum pad), plus a 20–25% margin. A 300 kg mold handled with a 40 kg gripper, for example, calls for a 500 kg hoist rather than a 350 kg one.

Power supply decides the series. Small workshops, garages or areas with only single-phase 220 V power suit a compact single-phase electric hoist rated 60–480 kg. Heavier loads and long daily running hours call for a three-phase 380 V hoist rated 125 kg to 20 tons, with an electromagnetic brake and IP55 dust and water protection.

Step 3: lifting speed: two-speed, variable frequency or servo

Lifting speed affects both output and how safely a load can be set down. A two-speed hoist is enough for general lifting; a variable-frequency hoist runs fast with no load and lowers gently under load; a servo hoist is for positioning to the millimeter.

Hoist type	Capacity	Lifting speed	Features	Best for
Single-phase electric hoist	60–480 kg	Two-speed, fast and slow	220 V supply, compact, easy to install and move	Assembly stations, shops without three-phase power
Three-phase electric hoist	125 kg – 20 t	Two-speed, fast and slow	380 V supply, electromagnetic brake, IP55, continuous duty	Machining, warehouses, long running hours
Hoist with adjustable slow lowering	250 kg – 1 t	Two-speed, adjustable slow lowering	Brushless motor, cut-off on overload, overheating and abnormal voltage	Mold setting, assembly that needs fine alignment
Variable-frequency chain hoist	125–5,000 kg	Stepless; half the usual low speed and up to 50% faster than the usual high speed	Soft start and stop, automatic slowdown near the upper limit	Lines that need fast lifting and soft lowering
Servo chain hoist	125–5,000 kg	Stepless 0–16 m/min, down to 0.05 m/min	Dual brake, speed and fault code display, precise positioning	Precision assembly, molds, CNC loading
Clean room hoist	125–2,000 kg	1–12 m/min (light loads), 0.5–4 m/min (2 t)	Chain in a bellows dust cover, 380 V supply	Electronics, pharma, photovoltaics

If operators have to guide the load into a bore by hand, also look at servo balancing hoists with float mode: the operator pushes lightly and the hoist follows the hand.

Step 4: the structure that carries the hoist

A hoist only performs well when it hangs from the right structure for the work area:

Ceiling-mounted rail: covers a whole line or several stations; the 5T steel rail carries 200 kg, the 500 kg rail carries 500 kg, and the 200 kg aluminum rail is very light to push.
Jib crane: serves one machine within a few meters of reach, on a fixed base, a wall bracket or a mobile base.
Push-type gantry crane: when the roof cannot take load or the hoist must move between areas, 500 kg to 2 tons.
Freestanding rail frame: stands on the floor, needs no ceiling drilling, and can be moved when the layout changes.

For lifting height, measure from the floor to the underside of the beam or rail, then subtract the height of the hoist, hook and tool. Low-ceiling plants should favor short-bodied chain hoists with aluminum housings.

Step 5: working environment and duty cycle

Dusty or humid shops need IP55 protection or better. Clean rooms need a hoist with a bellows-covered chain and a housing that does not shed paint. Areas with solvents or paint, explosion risk, or a strict no-heat requirement should not use an electric hoist at all; use an air hoist or a pneumatic crane instead: no heat and no sparks.

Duty cycle matters too: a few lifts per hour is fine for a two-speed hoist, but continuous lifting all shift with cycles under a minute justifies a variable-frequency or servo hoist to cut jerking, brake wear and operator fatigue.

Safety points when installing and using an electric hoist

Never exceed rated capacity; choose a hoist with overload cut-off, overheat cut-off and upper and lower limit switches.
Hooks need safety latches; check the chain, brake and emergency stop before every shift.
Never stand or put hands under a suspended load; lower the load to the floor before leaving it.
The supporting rail, jib or gantry must be designed for the hoist load plus a safety factor; never hang a hoist from an unverified roof purlin.
Electric hoists are lifting equipment and must be inspected before first use and periodically as required by local regulations.

Frequently asked questions

What is the difference between a single-phase and a three-phase electric hoist?

A single-phase 220 V hoist plugs into almost any workshop and suits loads of 60–480 kg. A three-phase 380 V hoist has a stronger motor and handles continuous duty better, from 125 kg to 20 tons, and is also available with variable-frequency or servo stepless speed control.

Should I choose an electric chain hoist or a wire rope hoist?

Inside a factory, for loads up to a few tons and moderate lifting heights, an electric chain hoist is compact, light and easy to hang from rails and jib cranes, so it is the common choice. Wire rope hoists suit large lifting heights or heavy double-girder cranes.

What capacity electric hoist do I need?

Take the heaviest load, add the weight of the tool (hook, gripper or vacuum pad), then add 20–25%. A 300 kg mold with a 40 kg gripper, for example, needs a 500 kg hoist.

When should I use a servo hoist instead of a standard electric hoist?

When loads must be placed accurately on fixtures, into bores or onto CNC machines, when lifting runs continuously all shift, or when operators need float mode to guide the load by hand. A servo chain hoist offers stepless speed from 0 to 16 m/min, down to 0.05 m/min.

Does an electric hoist need inspection?

Yes. Electric hoists are lifting equipment and must be inspected before first use and at regular intervals as local regulations require; FullSharp provides the equipment documents at handover.
