Drum wiring Trolley for OHE

The Drum Wiring Trolley is a specialized trolley used in Overhead Equipment (OHE) work by Indian Railways. Its main function is to transport and uncoil large drums of contact wire or catenary (messenger) wire during the stringing process. It moves on standard broad gauge railway tracks (1676 mm) and is essential for efficient and damage-free conductor laying.

This trolley comes with a rotating drum stand that allows the conductor to be pulled out uniformly while the drum rotates freely. It minimizes conductor kinking and damage, significantly improving the safety and speed of wire stringing operations.

Key Features:

• Material: Fabricated steel frame, coated for corrosion resistance

• Drum Holding Mechanism: Shaft-mounted with bearings for smooth rotation

• Capacity: Suitable for 1000–1500 mm dia drums, up to 2 tons

• Wheel Type: Rail-compatible flanged wheels, aligned to BG standards

• Mobility: Manual push-type or towable via motor trolley

• Braking System: Mechanical or drum friction brake for controlled uncoiling

• Optional Features: Stabilizing jacks, towing hook, wire guiding rollers

Applications in Railway Sector:

• Used during stringing of OHE contact and catenary wires

• Essential in new electrification, doubling/tripling, and OHE modification works

• Deployed by Railway Electrical Construction Units, PSUs, and OHE contractors

Advantages:

• Ensures smooth and tangle-free wire uncoiling

• Reduces manual labor and enhances productivity

• Durable design suitable for rugged railway environments

• Reusable across multiple projects

Compliance:

• As per RDSO and Indian Railway electrification standards

• Safe Working Load (SWL) certified for field operations
