The single-phase hoist, in 110V and 220V, will be sold in the do-it-yourself market, according to Cheng Day Taiwan sales manager John Pan.

The Netherlands-based distributor of Taiwanese-made hoists will be the first to sell the hoist. 120kg and 480kg models will follow.

Users turn a dial on the control to adjust the lower speed of the hoist.

Lifting speeds range from 3.4m/min to 13.4m/min.

The hoist uses brushless DC motors. More and more, inverter-controlled brushless DC motors with a high-magnetism excited magnet have a high torsion output and good control at low rotation rates, the company said. These motors are well suited to the needs of long hours of operation, large variation in loads and more frequent intermittent service, it said.
