Overhead & Gantry Crane Cables

Overhead and Gantry Cranes require reliable cable systems to deliver power, control signals and data throughout lifting, trolley travel and bridge movement. RouLine designs and manufactures custom overhead crane cables, gantry crane cables and bridge crane cables for festoon, reeling and other moving cable applications. Cable construction can be tailored to travel distance, bending requirements, installation conditions and operating environment.

Cable Requirements

Overhead and gantry crane cables must withstand repeated movement, mechanical stress and the operating conditions of the crane system. The required cable construction depends on whether the cable supplies power to the bridge, trolley or hoist, or transmits control and communication signals.

Key cable requirements include:

· Flexibility and bending resistance: Suitable conductor stranding and cable construction for repeated bending during trolley and bridge travel.

· Mechanical durability: Resistance to abrasion, tension and mechanical stress appropriate to the installation, especially in moving cable systems.

· Power and control transmission: Configurations designed for motor power, control circuits, auxiliary equipment and signal transmission.

· Suitable cable management: Flat or round cables selected according to the requirements of festoon systems, cable reels or other moving cable arrangements.

· Environmental resistance: Sheath materials selected for exposure to oil, moisture, UV radiation, temperature variations and other site-specific conditions.

· Customized electrical and mechanical specifications: Voltage rating, conductor cross-section, number of cores, travel length and cable dimensions matched to the equipment design.

Cable Solutions

RouLine provides custom cable solutions for overhead cranes, gantry cranes and bridge crane systems, supporting power supply, control and signal transmission during lifting, trolley travel and bridge movement. Depending on the cable routing, travel distance, bending requirements and operating environment, we customize cable constructions for festoon and reeling systems, with suitable conductor configurations, insulation and sheath materials for each application.

Reeling Cable 

For continuous cable winding and unwinding on crane reels, Reeling Cables are designed for high dynamic flexibility, tensile loads, long travel distances, and harsh outdoor environments.

FAQ

1. What types of cables are used in overhead and gantry cranes?

Overhead and gantry cranes commonly use festoon cables, reeling cables, power cables and control cables. The suitable type depends on the crane structure, cable movement, power supply arrangement and control system requirements.

2. How do I choose cables for overhead and gantry cranes?

Cable selection depends on the rated voltage, current, travel distance, bending frequency, installation method and operating environment. These factors help determine the conductor configuration, cable structure and sheath material required for reliable operation.

3. What is the difference between festoon cables and reeling cables for cranes?

Festoon cables move along a track with a suspended cable system, while reeling cables are wound onto and unwound from a cable reel as the crane moves. The appropriate solution depends on the crane layout, travel distance and cable management system.

4. Can overhead crane cables and gantry crane cables be customized?

Yes. Custom crane cables can be designed according to the equipment's electrical and mechanical requirements, including conductor cross-section, number of cores, voltage rating, cable length, shielding and sheath material. Existing drawings or cable specifications can help define the required construction.
