Why APPI: Over time, the accumulation of sludge on the inside walls of pipes carrying crude oil reduces flow and in severe cases can block the flow.  To remove the crud, a “pig,” which is designed to scrape the walls of the pipe, is pulled through it as part of a regular maintenance routine. Then, a cart, which carries the pig, is pulled on a track between entry points and its stowed location by one of our Columbia WG5600 HAZLOC-rated explosion-proof winches.

As this operation is conducted in a potentially explosive atmosphere, the winch was equipped with an explosion-proof motor.  To further reduce the chance of sparking, stainless steel wire rope with a stainless steel latching hook is used on the winch.  Power for this HAZLOC rated explosion-proof winch was routed through appropriately rated conduit to an explosion proof, foot pedal control.
