The floor mounted jib crane is a kind of crane used in conjunction with a hoist, also known as pillar mounted jib crane, free standing jib crane, column jib crane and cantilever crane.
The jib crane is composed of a column, a slewing arm, a slewing drive device and an electric hoist. The lower end of the column is fixed to the concrete foundation by anchor bolts, and the cycloid pinwheel reducer drives the cantilever to slew. The electric hoist runs straight left and right on the cantilever I-beam and lifts heavy objects. The crane cantilever is a hollow steel structure with light weight, large span, large lifting capacity, and is economical and durable. The jib crane uses a built-in traveling mechanism and adopts special engineering plastic wheels with rolling bearings. It has low friction, light travel, and small structural dimensions, which is particularly beneficial for increasing the hook stroke.
The column type jib crane has the advantages of novel and simple structure, simple operation, flexible rotation, and large working space. It is an energy-saving and efficient material lifting equipment. It is widely used in factories, mines, workshops, production lines, assembly lines, machine tools, and heavy lifting in warehouses, docks and other places. In particular, the use of cantilever cranes in production lines with dense equipment, short-distance lifting, and frequent operations can improve production efficiency.

Pillar/Column: The vertical structure supporting the entire crane. Mounted to the floor or foundation to provide stability. Made from high-strength steel for durability.
Jib Arm: The horizontal beam or arm that supports the load. Can be fixed or rotating (usually rotates up to 360° or a limited range). Designed to withstand bending and torsional stress.
Slewing Mechanism: Allows the jib arm to rotate around the pillar. Can be manual or motorized, depending on the application.
Hoist: The lifting mechanism attached to the jib arm. Includes a motor, wire rope, chain, or hook for lifting and lowering loads. Operated electrically, pneumatically, or manually.
Trolley (Optional): A mechanism that moves horizontally along the jib arm to position the load.
Base/Floor Mounting Plate: The part where the pillar is fixed to the floor or foundation. Requires strong anchoring for stability under load.
1 Space Efficiency: Requires minimal floor space since the crane is mounted on a pillar, leaving the rest of the area free for other operations.
2 High Flexibility: The rotating jib arm allows for easy coverage of circular or semi-circular areas. Suitable for various lifting and material-handling tasks within its range.
3 Cost-Effective: Lower installation and operational costs compared to overhead cranes or gantry cranes.
4 Ease of Installation and Maintenance: Simple design allows for quick installation without requiring major structural modifications.
5 Increased Productivity: Improves workplace efficiency by enabling quick and precise load positioning.
6 Versatility: Can handle different load types with interchangeable load-handling devices (hooks, grabs, magnets, etc.). Works well in conjunction with other cranes or machinery for complex operations.
1 Manufacturing and Assembly Lines: Loading and unloading components, positioning parts for assembly, moving tools, dies, or finished products.
2 Warehousing and Logistics: Lifting and transporting goods in storage areas, assisting with pallet stacking and sorting, loading and unloading trucks or containers.
3 Automotive Industry: Assembling vehicle parts on production lines, handling engines, transmissions, or large components.
4 Machine Shops: Handling heavy machine parts or tools, removing or installing components during maintenance.
5 Construction Sites: Lifting and positioning materials like beams, pipes, or equipment, assisting with assembly or installation tasks.
6 Maintenance and Repair: Supporting tasks that require lifting and holding heavy equipment, replacing parts or repairing machinery in confined spaces.
7 Foundries and Metalworking: Handling molds, castings, or raw materials, assisting with forging, welding, or metal assembly.
8 Marine and Port Applications: Loading and unloading small cargo, assisting with maintenance of marine engines or equipment.
