These turntables play a crucial role in maintaining and inspecting overhead equipment (OHE) used in railway and metro projects. Here are some key points:
Purpose of Turntables:
Turntables allow workers to rotate the contact wire (catenary wire) for inspection, repair, or replacement.
They facilitate access to different sections of the OHE system without dismantling the entire setup.
Design Considerations:
Structure: Turntables consist of a circular platform mounted on bearings. The platform can rotate horizontally.
Size: The size of the turntable depends on the specific requirements of the project.
Motorization: Some turntables are manually operated, while others have motorized mechanisms for rotation.
Alignment: Proper alignment with the contact wire is essential to ensure accurate positioning during maintenance.
Usage Scenarios:
Maintenance: Turntables are primarily used during routine maintenance, inspections, and troubleshooting.
Emergency Repairs: In case of damage or faults in the contact wire, turntables allow quick access for repairs.
