0.5t To 10t Vital Chain Pulley Block

Save time and increase efficiency with the world`s first dual speed manual chain hoist. Hsz-c innovative magnetic clutch technology senses the load and changes gears automatically to work seven times faster when repositioning an unloaded hook. The result is a significant reduction in labor costs and operator fatigue – something both your workers and your accountant will appreciate. safe, reliable, mechanical brakethe hsz-c gives you added protection with its double pawl springs, providing redundancy and extra-reliable operation of the brake mechanism. With a double-enclosed brake cover, you can be sure that dust, rain and dirt are kept out, and that that the mechanical brake activates instantly. efficient, maintenance-free sealed bearingslow-maintenance features like sealed bearings protect from contamination and provide years of worry-free service. This contributes to the efficient drive chain and minimizes the manual effort required to operateautomatic speed controlin an unloaded or lightly loaded state, a magnetic clutch is automatically activated allowing the hoist to operate in high-speed mode. Once a load heavier than approximately 10 per cent of capacity is applied, the magnetic clutch releases and the standard clutch activates, putting the hoist back into standard-speed mode. all-steel gear case &hand wheel coverincreased strength and dependability can be expected from the hsz-c rugged steel housing and double-steel plate construction.
