The column supports and fixes the swivel arm of the column jib crane. The column jib crane adopts single-row tapered roller bearings to withstand radial force and axial force, which ensures the stability and safety of the column jib crane.

The swivel arm is welded by the combination of I-beam. The swivel arm allows the electric or manual trolley to move horizontally, and also allows the electric hoist to lift up and down and rotate around the column. The design of the swivel arm makes the column jib crane more flexible and efficient.

The support arm can support the swivel arm and increase the bending resistance and strength of the swivel arm.

The roller is driven by the reducer to realize the electric slewing of the jib. The combination of support arm and reducer makes the slewing function of the column jib crane more stable and reliable.

Electric chain hoist is the key component of the column jib crane to lift heavy objects and move horizontally along the swivel arm. The electric chain hoist can work efficiently and move horizontally and vertically to meet the needs of various lifting operations.

The electric part adopts C-rail plus flat cable power supply system, low voltage inter-control type safety voltage for operation. Hand electric door push button to realize the control of the column jib crane, including the fast rise, fast fall, slow rise, slow fall of the electric chain hoist, as well as the walking of the hoist running trolley and the left and right slewing of the column jib crane. The collector ring inside the column provides electricity to make the swivel arm rotate arbitrarily. The collector ring ensures the safe and reliable operation of the column jib crane.
