Hoist drive

ST series chain hoists are driven by a reliable pole-changing AC Asynchronous Induction Motor (2/8 poles). After deceleration by meshing gears, the chain wheel is driven to rotate, thereby dragging the chain to run up and down, lifting and lowering heavy goods.

The motor and brake are arranged on one side of the gearbox. The brake adopts power-off braking control. When the flashlight gate is released or the current is cut off, the brake pressure spring returns to ensure safety.

An oil (wet) friction clutch is installed in the second-stage deceleration mechanism, and the pressure on the clutch is adjusted through an external nut to control the slipping force of the clutch, so that the clutch slips under the set clutch force and prevents the hoist from lifting greater than the rated lifting capacity, it plays the role of overload protection. The friction clutch meets the Chinese national standard and refers to the requirements of FEM/ISO/EN standard for load control equipment. The overload coefficient can be adjusted from 1.3 to 1.6 times, and the factory standard setting is 1.4 times.

The lifting chain is made of high-strength and wear-resistant materials; the surface has a high degree of hardening, and the surface is treated with galvanized anti-rust treatment, which meets the GB20947 standard.

Chain lubrication is very important for the chain. Before using the hoist, please apply the supplied chain oil on the surface of the chain.

ST series hoist is equipped with upper and lower limit.

The friction clutch protects the hoist from overloading to avoid lifting loads more than the rated lifting capacity.
