Line Pull: 1,100 pounds
Line Speed: 0-14.5 feet per minute

Why APPI: A U.S. based company contracted for renovations to ETA Guandu contacted APPI to replace the electric crawler drives on sediment removal systems. They required systems designed for continuous submersion with minimal maintenance, as five million people would depend on their operation for clean drinking water.

APPI supplied three Columbia TD1100 traction drive systems with sheave assemblies at both ends of the tank and line tensioning units with rope stretch sensor provisions. The traction drives include marine-duty motors, stainless steel hardware, and an epoxy overcoat to guarantee minimal maintenance.
