The chain hoist is manufactured with motor housing, which is made of aluminum alloy casting that features rigid structure and light weight. The motor is framed with radiant cooling fins, which permits 40% (dual speed 40/20%, YSF-series 15%) duty cycle. As for the chain hoist motor brake, we develop an advanced element called "Electro-Magnetic Brake Controller"; it's a unique design in its field, R.O.C. Patent No. 27417 features simultaneous braking upon release of P.B. even under full load.

The limit switch of the chain hoist is fitted at both top and button ends shuts off power automatically to prevent load chain from running out. The load chain is made of grade 80 case hardened alloy steel. On the other hand, we adopt hot forged high tensile steel to make its hook. Hence, the hook is rigid and durable with 360 swivels, fitting with safety latch to assure safe lifting.

The chain hoist bracket is made of double high-tensile alloy steel plate, featuring rugged and durable construction. The mechanical brake is designed advanced that assures secure braking even under overload. In conjunction with motor brake, features "DOUBLE BRAKE SYSTEM" for safety and durability in hoist operation. Our chain hoist factories spare no expense in maintaining the quality assurance, increasing manufacturing efficiency, spending huge sums of money to import advanced manufacturing equipment and insisting on equipments first and quality first.
