1.Aluminum bronze or beryllium bronze as the blank, hand pull gourd shell using H62 copper alloy material. 1 ton chain fall can be used in flammable and explosive occasions, such as chemical industry, sea and other operations.
2.The rotary gear 10 ton chain falls after high temperature heat treatment, so as to achieve a very high wear resistance. Manual chain hoist with small pulling force, light weight, easy to carry, beautiful appearance, small size, durable.
3.20 ton chain fall work principle: by trolling dynamic bracelet, hand chain wheel begins to rotate, friction slices ratchet wheel and brake block begin to rotation, five tooth long axis of rotation gear, four teeth short shaft and spline hole gear. Thus, the lifting chain wheel on the spline hole gear drives the heavy chain to lift the heavy load smoothly.
Manual chain hoist is mainly used in factories, mines, construction sites, piers, docks, warehouses and other places, for the installation of machinery, lifting goods, especially for the outdoor and no power supply operation which showed its superiority.
