1. Gear
They are innovated symmetrical arrayed high speed synchronous gears, and are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving.
Standard international gear steel is two times as wear-resisting degree as the ordinary chain block, rotation is more stable and hand pulling force is more light.
2. Chain
Adopt high strong chain and high precision welding technology, meet ISO3077-1984 international standard; fit for gusty overload work conditions; bring your hands a better feeling; multi-angle operation:
changing the ordinary chain block only vertical downward pull, fit to greater scope.
Hand Chain: material A3, 30 grade,galvanized,
Manual lifting chain hoist
