US Safety Trolley Tightwire — Replacement Collectors for Tightwire Conductor Bar Systems
US Safety Trolley discontinued new system orders for Tightwire conductor bar on January 31, 2022.

Tightwire is a compact, lightweight single-piece conductor bar system rated at 90A, designed for overhead crane, hoist, and monorail installations where minimizing space requirements and installation hardware was the primary specification driver. The tandem collector assembly rides the Tightwire conductor bar as the crane or trolley travels, maintaining continuous electrical contact between the energized conductors and the crane power circuit.
