Dropper Making JIG Bench

The Dropper Making JIG Bench is a stationary workshop fixture designed for the precise preparation of dropper wires used in Overhead Equipment (OHE) systems of Indian Railways and Metro Rail networks. It enables technicians to measure, cut, and bend cadmium copper or hard-drawn copper droppers to exact specifications based on sag and span charts.

Installed in TRD depots, OHE fabrication yards, or electrification work sites, this bench provides consistent quality and dimensional accuracy for droppers, which are critical for ensuring the uniform geometry of the contact and catenary wires.

Key Features:

• Structure: Heavy-duty MS or aluminum alloy bench with anti-corrosive coating

• Jig Plate: Machined surface with guide slots for length and angle calibration

• Markings: Graduated scale or metric ruler for precise measurement

• Clamping System: Dropper holding clamps to fix wire in position during cutting and shaping

• Cutting Tool Support: Provision to mount or manually use wire cutters and bending tools

• Bench Type: Floor-mounted or portable bench-top variant

Applications in Railway Sector:

• Fabrication of OHE droppers with consistent length and bend accuracy

• Used in construction and maintenance of overhead traction systems

• Supports CORE, RVNL, Metro Rail, and Electrical Division OHE works

Advantages:

• Improves speed and uniformity of dropper preparation

• Reduces human error and enhances quality of OHE installations

• Robust and durable for repeated field or depot use

• Ensures compliance with railway sag chart specifications
