High quality electric HSY hoist

  This machine adopts high strength aluminum alloy body, beautiful appearance, compact body, small volume, light weight, using two gear transmission, high-speed level for helical gear transmission, so the transmission is smooth, low noise; the main parts of this machine are made of high alloy steel materials, and through a number of special heat treatment process, with high strength, good wear resistance, etc., the upper and lower hooks are made of high strength alloy steel, after strengthening heat treatment with high toughness, even if the body caused by overload damage, the hooks will only plastic deformation, but will not occur brittle fracture.
