The RY frosted hand chain hoist replaces the traditional steel sleeve friction and improves the rotation efficiency. It is a three-bearing hand chain hoist. It is made of solid materials. The hand chain hoist is light and labor-saving.RY frosted black hand chain hoist is based on the traditional hand chain hoist. It adds a bearing connected to the main shaft, which reduces friction and improves the transmission efficiency between gears, thus achieving the effect of being light and labor-saving.
