Fan doors made of HDPE = NO hydraulics!
Poly works on air pressure, unlike heavy steel fan doors that need hydraulics to open/close.
Polyline’s cable stoppers have been specifically designed for Mining Underground cables that power Jumbo’s and all other electric rigs.
It was found that other standard cable stoppers had protruding bolts which caused serious injury to personnel and equipment when the cable was being wound in.
With Polyline’s cable stoppers, prevention played a huge part in the design. The cable stopper is easily assembled with Stainless Steel bolts that drive into built-in nut sockets so all components discretely sit within the polyurethane housing.
The cable stopper grips the electrical cables with an inner thread, not pinching it or damaging the integrity of the cable.
Polyurethane is inert and will not corrode.
Polyline’s cable stoppers come in five standard sizes. Contact Us today for a free quote or a custom size.
