Structure and Applications of a Jib Crane

Composition of jib crane


Jib crane mainly consists of columns, rotary arm rotary drive device and electric hoist. It is fixed on the concrete foundation with anchor bolts under the column. The overhanging arm can be rotated by the cycloid pinwheel reduction device. The electric hoist travels left and right on the overhanging I-beam and lifts the heavy objects.


The inner part of the overhanging arm is a hollow steel structure with the characteristics of light weight, large span, large lifting capacity, economy, and durability. The walking mechanism inside the overhanging arm is made of special engineering plastic with rolling bearings, which has the advantages of small frictional force, fast walking speed, and small structural size, providing great advantages for increasing the hook's travel distance.

Jib cranes can effectively shorten preparation and non-productive working time, and reduce unnecessary waiting. With various specifications and complete types, jib cranes are suitable for different requirements in terms of lifting weight, rotation angle, arm length, and function. They have the common advantages of being light weight, having a long overhanging arm, being able to lift heavy objects, having simple installation, operation and maintenance.


They are completely independent and are an ideal type of lifting equipment for the workplace. They are also very suitable for outdoor cargo yards and loading platforms, and can save installation space. Additionally, they can achieve maximum lifting height in cases where the lifting clearance is very small. Electric jib cranes are a new generation of lightweight lifting equipment made to adapt to modern production, and are especially suitable for short-distance, frequent and intensive lifting operations, with the highly reliable JPK type ring chain electric hoist. They feature high efficiency, energy saving, simplicity, small installation space, and easy operation and maintenance.


Movable jib cranes are more flexible and adaptable, and are necessary emergency lifting equipment for efficient automated production lines, ensuring smooth production. The curved arm jib cranes have the characteristics of novel structure, flexible extension, convenient operation, high efficiency and energy saving.


During operation, the load is lifted by pressing the electric button. Using the bending and rotary movement of the crossbeam, obstacles in the control working area are avoided, maximizing the working area. The operation area can be easily reached by lightly pushing and pulling. 


Therefore, jib cranes the preferred choice for a variety of occasions, with convenience and speed as inherent advantages.
