Cantilever crane fetching device rotating hanging on the arm end or rotating hanging on the arm can run along the lifting trolley, rotating arm can be turned, but not pitching jib crane is called cantilever crane. Cantilever crane is a small and medium-sized lifting equipment developed in recent years, unique structure, safe and reliable, with high efficiency, energy saving, time-saving, flexible and other characteristics, three-dimensional space free operation, in the distance, intensive transport occasions, than other conventional lifting equipment more shows its superiority. This product is widely used in various industries in different places. Cantilever crane working strength is light, the crane is composed of column, rotary arm rotary driving device and electric hoist, the lower end of the column is fixed on the concrete foundation by the anchor bolt, by the cycloid pin gear reducer to drive the rotary arm, electric hoist in the spiral arm I-steel for straight line running, and lifting heavy objects. Crane arm is hollow steel structure, light weight, large span, large lifting weight, economic and durable. The MODE walking mechanism of built-in rotary arm crane adopts special engineering plastic walking wheel with rolling bearing, which has small friction force and brisk walking. Small structure size, especially conducive to improve the hook stroke.
