Wall Travelling Jib Cranes

What Is a Wall Travelling Jib Crane?

A wall travelling jib crane is a type of jib crane that not only rotates its boom but also travels horizontally along a runway mounted on a wall or a row of building columns. Unlike a standard fixed-wall jib crane, which stays in one location, this crane can move along the wall to serve multiple workstations or a long, narrow workspace.

Lifting Capacity:0.25 – 5 tons (up to 10 tons for heavy-duty)
Jib Length (Span):2 – 7 meters
Travel Length (Runway):Customizable based on workshop length
Rotation Angle:180° (standard) or 270° (corner mount)
Travel Speed:Typically 20 – 30 m/min
Control:Pendant or wireless remote
Hoist Options:Manual, electric chain, or wire rope hoist

 

Horizontal Travel Capability – The entire crane assembly moves along a wall-mounted track or runway, extending its service coverage along the length of a workshop or production line.

Rotation + Travel – Combines boom rotation (typically 180° or 270°) with longitudinal movement, providing a large rectangular working envelope.

Space-Saving Design – Like fixed wall jib cranes, it occupies no floor space, keeping the ground area clear for machinery and personnel.

Cost-Effective Coverage – Offers a more affordable alternative to overhead bridge cranes for covering long, narrow work areas.

Flexible Control – Can be operated via pendant or wireless remote, allowing the operator to move the crane and handle loads from a safe position.

 

Structural Support System
The crane runs on a wall-mounted runway beam or track fixed to building columns. A traveling carriage moves along this track, supporting the entire crane. The jib boom extends outward from the carriage, and a slewing bearing at the connection allows rotation.

Lifting System
A hoist trolley travels along the underside of the boom, carrying the hoist (manual chain, electric chain, or wire rope). The hoist lifts and lowers the load via a hook or attachment.

Movement Systems
Three motions are possible:

Longitudinal travel – powered by a travel drive and wheels along the runway.

Boom rotation – manual or motor-driven via the slewing bearing (typically 180° or 270°).

Hoist traverse – the trolley moves along the boom for lateral positioning.

Control & Electrical System
The crane is operated via pendant control or wireless remote. A control panel houses electrical components, while a festoon cable system or conductor bars supply power along the runway.

Safety Devices
Key safety features include limit switches (for travel, hoist, and rotation), overload protection, emergency stop buttons, and buffer stops at runway ends to prevent over-travel.

 

 

1. Space Efficiency
The crane is mounted on the wall or building columns, occupying zero floor space. This keeps the ground area completely clear for machinery, workpieces, and personnel movement.

2. Extended Coverage
Unlike fixed wall jib cranes, the traveling version moves horizontally along a runway. This allows it to serve multiple workstations or cover a long, narrow workspace with a single crane.

3. Cost-Effective Solution
For long, linear facilities, one traveling jib crane can replace several fixed jib cranes or serve as a more affordable alternative to a full overhead bridge crane.

4. Flexible Operation
The crane offers three directions of movement: longitudinal travel along the runway, boom rotation (typically 180° or 270°), and hoist traverse along the boom. This provides excellent positioning flexibility.

5. Ergonomic and Productive
With pendant or wireless remote control, operators can handle loads easily from a safe position. This reduces manual effort, minimizes fatigue, and improves overall productivity.

6. Easy Installation and Maintenance
The modular design simplifies installation on existing walls or columns. Standardized components make maintenance and spare parts replacement straightforward.

7. Safety Features
Built-in safety devices include limit switches, overload protection, emergency stops, and end buffers, ensuring reliable and safe operation.

1. Manufacturing and Assembly Lines
Used for feeding materials to machines, lifting components for assembly, and moving finished products along production lines.

2. Machine Shops
Ideal for loading and unloading heavy workpieces onto lathes, milling machines, and other machine tools at multiple stations.

3. Warehouses and Storage Areas
Efficient for moving goods along storage aisles or loading and unloading at different bays.

4. Automotive Industry
Handles engine blocks, transmissions, and other heavy parts on automotive production lines.

5. Maintenance and Repair Workshops
Assists in lifting and positioning heavy machinery parts for servicing across a long workshop bay.

6. Loading Docks and Shipping Areas
Provides flexible lifting support for moving cargo along the dock area.

 

The production procedure of a floor-mounted jib crane involves several steps, from design and manufacturing to assembly and testing. Here is a general overview of the production procedure for a floor-mounted jib crane:

 

1.Design Phase:

• Project Requirements: Understand the specific requirements of the customer, including lifting capacity, working radius, height, and any special features needed.
• Engineering Design: Create detailed engineering drawings and specifications for the floor-mounted jib crane, considering factors such as material strength, safety standards, and operational requirements.

2.Material Selection:

• Choose high-quality materials for the various components of the crane, including the base, column, jib arm, boom, hoist trolley, and other structural elements. The materials should be selected based on factors like strength, durability, and resistance to environmental conditions.

3.Fabrication:

• Cut and shape the raw materials according to the design specifications.
• Weld the components together to form the main structure of the floor-mounted jib crane.
• Ensure precision and accuracy in the fabrication process to maintain structural integrity.

4.Surface Treatment:

• Apply surface treatments such as painting or coating to protect the crane from corrosion and environmental wear.
• Surface treatments may include priming, painting, or galvanizing, depending on the materials used and the intended application.

5.Assembly:

• Assemble the various components, including the base, column, jib arm, boom, hoist trolley, and any additional features according to the engineering design.
• Ensure that all connections are secure and that the crane is structurally sound.

6.Installation of Mechanical Components:

• Install the hoist mechanism, rotation mechanism, and other mechanical components.
• Connect the electrical components, including wiring, control panels, and safety features.

7.Quality Control and Testing:

• Conduct thorough quality control inspections at different stages of the manufacturing process to ensure compliance with design specifications and industry standards.
• Perform load testing to verify the crane's lifting capacity and overall functionality.

8.Documentation and Certification:

• Prepare documentation, including user manuals, maintenance instructions, and certification documents.
• Ensure that the floor-mounted jib crane complies with relevant safety and quality standards.

9.Packaging and Shipping:

• Package the floor-mounted jib crane securely to prevent damage during transportation.
• Arrange for shipping to the customer's location.

10.Installation and Commissioning:

• Provide on-site installation services or detailed installation instructions for the customer.
• Commission the crane, ensuring that all components function correctly and safely.

11.Training:

• Offer training to operators on the proper use, maintenance, and safety procedures associated with the floor-mounted jib crane.

12.After-Sales Support:

• Provide ongoing support, including maintenance services, spare parts availability, and troubleshooting assistance.
