Composition and Function Analysis of Pillar Jib Crane

Pillar jib crane is a light-duty workstation lifting equipment with the characteristics of high efficiency, energy saving, trouble-free, small footprint, easy operation and maintenance. It is mainly composed of a column, a rotating arm, a support arm and a reducer, a chain electric hoist, and an electrical part.

Column: The column plays the role of supporting and fixing the rotating arm of the pillar jib crane. It uses a single-row tapered roller bearing that bears radial and axial forces to ensure the stability and safety of the cantilever crane.

Rotating arm: The rotating arm is a component welded by combining I-beams and supports. It has the functions of electric or manual trolleys to achieve horizontal movement and the up and down lifting of electric hoists, and can rotate around the column. The design of the rotating arm makes the work more flexible and efficient.

Support arm and reducer: The support arm plays the role of supporting the rotating arm and increasing the bending resistance and strength of the rotating arm. The electric rotation of the cantilever is realized by driving the roller through the reducer. The combination of the support arm and the reducer makes the slewing function of the freestanding jib crane more stable and reliable.

Electric chain hoist: The electric chain hoist is a key component in the freestanding jib crane that lifts heavy objects and moves horizontally along the rotating arm. It has efficient lifting capacity and flexible movement ability, which can meet the needs of various lifting operations.

Electrical part: The electrical part adopts a C-rail plus flat cable power supply system, and operates with a low-voltage inter-controlled safety voltage. The flashlight button realizes control, including the fast rise, fast fall, slow rise, slow fall of the chain electric hoist, the walking of the hoist running trolley and the left and right rotation of the jib crane. The collector ring in the column provides power supply for any rotation of the cantilever, ensuring the safe operation of the column mounted jib crane.

Through the above composition and function analysis, we can clearly understand the components of the column mounted jib crane and the role of each component. Its design makes it particularly suitable for short-distance, frequent and intensive lifting operations, providing an efficient and convenient solution for the workplace.
