Jib cranes are an essential lifting solution for a wide range of industries, primarily used for precise, repetitive material handling in localized workspaces. How Does a Crane Jib Work depends largely on the type of construction and how it is mounted. Jib cranes can be mounted on floors, walls, and mobile bases. Jib cranes utilize a jib (or boom) to support and efficiently move loads within a specific radius.
In this article, we will take you through the working principle, main components, application scenarios, different types, advantages, and disadvantages of jib cranes. Read on for a comprehensive look at jib cranes and how they can improve lifting efficiency.
The working principle of a jib crane is simple; at its core, it is based on a horizontal arm (also known as a jib or boom) that is attached to a vertical support, either a column mounted on the floor or a bracket on the wall. The lift moves horizontally along the cantilever, lifting and transporting loads within a circular or semi-circular working area. The cantilever has a swivel range of 180° to 360°, allowing flexible handling of loads in localized areas. Depending on the system design and workload requirements, lifting and moving operations can be either manual or motorized.
Jib (Boom): Horizontal beam that supports the crane and allows it to move laterally. It determines the reach and working area of the crane.
Column or Mounting Bracket: Vertical column (optional freestanding or floor-mounted) or wall bracket (wall-mounted) that supports the jib and allows it to rotate.
Lift: A lifting device mounted on a trolley that moves along the cantilever. Electric, manual, or pneumatic options are available.
Trolley: A Mechanical device that moves the electric hoist horizontally along the cantilever for smooth operation.
Slewing mechanism: Rotates the cantilever 180°~360°. Depending on the load capacity and frequency of operation, it can be manual or electric.
Base plate or wall bracket: Provides structural support and anchoring to ensure safe operation.
Electrical control system: Includes pushbutton station or remote control for operation of the lifting and rotating mechanisms.
There are several types of jib cranes, including column, wall-mounted, and folding jib. Here are a few common types, features, and applications:
| Tipo | Mounting | Capacidad de elevación | Rotation Angle | Key Features | Aplicación |
|---|---|---|---|---|---|
| Freestanding Jib Crane | Floor-mounted with foundation | Up to 5 tons | 360° | Independent structure; ideal for open workspaces | Loading bays, workshops |
| Wall-Mounted Jib Crane | Mounted to the wall and moves along a rail | Up to 2 tons | 180° | Space-saving; no floor obstruction | Assembly lines, fabrication areas |
| Wall-Traveling Jib Crane | Mounted to wall and moves along a rail | Up to 1 ton | Horizontal travel | Covers linear zones along walls | Production lines |
| Mobile Jib Crane | Wheeled or base-mounted | Typically up to 0.5 ton | Varies | Portable and flexible | Light-duty lifting, small workshops |
| Articulating Jib Crane | Floor or wall-mounted | 150–500 kg | Multiple joints | Multi-axis movement | Mounted to the wall or column |
Manufacturing plants: For moving components between workstations or machines.
Warehouses: Assisting in loading/unloading goods from vehicles or storage areas.
Assembly lines: Supporting precise and repetitive lifting in tight areas.
Shipyards: Handling tools, parts, or equipment during vessel assembly.
Metalworking and machining shops: Assisting operators in handling heavy molds or fabricated parts.
Logistics and distribution centers: Streamlining order fulfillment and package handling.
We suggest you to choose the right type of jib crane depends on workspace layout, load handling needs, and desired automation level.
Operating a jib crane involves the following steps:
Inspect before use: Check for visible damage or wear on hoist, trolley, and structure.
Power on the system: Ensure the crane is connected to its electrical source if motorized.
Position the jib arm: Rotate the jib arm manually or via motor to align with the load.
Lift the load: Use the hoist control panel to raise the load safely.
Move horizontally: Slide or drive the trolley along the jib to position the load.
Lower the load: Carefully lower the load at the destination point.
Return the arm: Move the jib back to the starting position after use.
Power off and secure: Turn off the system and conduct any necessary post-operation checks.
Never exceed rated load capacity.
Avoid sudden movements or swinging loads.
Keep the area below the load clear of personnel.
