产品介绍
Electric free standing jib cranes feature a low-headroom jib design that provides greater lifting height and fully electric operation. With their strong load capacity, electric free standing jib cranes are perfectly suited for repetitive material-handling operations, whether at a single workstation or across multiple points in the production area. They help reduce handling time, minimize operator fatigue and workplace injuries, and deliver safe, efficient performance. The unlimited rotation angle offers significant advantages, especially in large working areas.
Electric free standing jib cranes provide full 360° unobstructed coverage, with electric slewing, trolley travel, and hoisting. All components are manufactured using precision laser-cut parts for higher accuracy, improved appearance, and enhanced duty ratings. They are widely used in manufacturing, assembly, warehousing, and other industrial environments.
Electric Free Standing Jib Cranes Structural Composition
Main Structural Components
Electric Free Standing Jib Cranes typically consist of the following components:
- 柱子： Made from tubular steel or rolled sections, the column is the core load-bearing structure, providing high rigidity and stability.
- Jib Arm: Connected to the column and capable of rotating around it. Designed with high-strength materials and optimized structure to minimize deformation. The jib length can be customized to suit different working radii.
- Slewing Mechanism: Controls the rotation of the jib. Options include electric or manual slewing. Electric units feature a motor, gearbox, and slewing bearing for precise rotational control.
- Electric Hoist: Travels along the jib arm, performing lifting and horizontal movement of loads. Both chain hoists and wire rope hoists are available, depending on speed, load capacity, and duty requirements.
- Base Plate and Reinforcements: A thick base plate and steel reinforcement plates are used to strengthen the column. Typically secured with 7–8 anchor bolts for maximum stability.
- Bearing System: Self-aligning bearings are used to withstand vertical, horizontal, and radial loads, ensuring smooth slewing motion.
Hoist Options Available
Electric free standing jib cranes（column mounted jib crane） can be equipped with different types of electric hoists and slewing mechanisms to meet a wide range of operating requirements. Depending on the load and desired operating speed, available options include electric chain hoists, electric wire rope hoists:
Compact, lightweight, and designed with a chain running inside the sprocket to prevent slippage or derailment. It offers stable performance with high duty rating, long service life, low maintenance needs, and excellent cost efficiency. Ideal for medium to light loads and frequent lifting cycles. Its lifting speed, however, is generally slower than that of wire rope hoists.
A high-speed lifting device suitable for single-girder overhead cranes, gantry cranes, and jib cranes. With minor modifications, it can also function as a winch. It features high lifting speed and efficiency, making it ideal for applications requiring long lifting heights and heavy loads. Compared with chain hoists, wire rope hoists are larger and heavier.
