Hand chain hoist: pull the hand chain
A hand chain hoist on a beam clamp, hooked into a motor's lifting eye. Pick the hoist size and the load, then hold to pull the hand chain (or lower it) and watch the hook rise. The picture shows how your pull, the gear ratio and the efficiency add up to the lift.
Open full screen · Exam preparation only: always check the hoist's rating, the manufacturer's data and your lift plan.
What this simulator works out
Your pull on the hand chain, from the maker's pull at rated load scaled to the load on the hook; the feet of hand chain pulled for each foot of lift (the overhaul ratio); and the efficiency lost in the gears and the brake. Hoists from ½ to 5 tons, imperial or metric.
Worked example
- Imperial: a 1 ton hoist (rated 2,000 lb) needs 58 lb of pull at rated load. Lifting a 1,500 lb motor: 58 × 1,500 ÷ 2,000 = 43.5, about 44 lb of pull. The load is 75 % of the hoist's rating.
