The common/trade name for this is chain fall or chain hoist, and widely used by tradesmen to lift heavy objects when a Lull (material handling forklift) isn’t an option.

Modern chainfalls use one loop of chain to drive a gear reduction which drives a separate load chain. Differential chain hoists with an upper and lower pulley and no gear reduction are found in museums.
