Columbia Winch System

Why APPI: This Dual Winch Positioning System uses two Columbia WN20000-4A17-L-01 AC Electric Winches to open and close a flood gate in southern Louisiana.  The operator interfaces with a NEMA 4X stainless steel control enclosure; the panel houses two reversing starters which power the winch gearmotors.

Installed on the enclosure’s panel face are OPEN & CLOSE buttons, power indicator light, fused manual disconnect and an emergency stop button.  For added security, the power switch and winch select switches are both keyed.  Gate over travel is prevented by roller lever limit switches wired directly to the control enclosure.

A 3-part epoxy and polyurethane paint treatment on the winches will ensure long-term performance in the marine environment.

APPI worked closely with project engineering team to create a system that was reliable while also being simple to operate.
