Features
|
Patented piston design Single or dual piston provides wider range of applied tension with greater control. Drop in powerhead package Standard single piston elements can be retrofitted with a dual piston powerhead to provide increased control. Split wear spacers The split wear spacers allow for wear adjustment without disassembly of the brake to minimize downtime and maintenance costs. Unique friction couple A specially formulated friction material, interfacing with a copper alloy surface, eliminates the stick-slip characteristic associated with ordinary frictional devices. Rapid heat dissipation The copper interface conducts heat rapidly to the circulating coolant. Open or closed loop coolant systems The element works equally well with open or closed loop circulating systems. On mobile equipment, the engine’s cooling system can be tapped to provide coolant to the element. Optional corrosion protection For marine environment applications, protective coatings are available to minimize corrosion |
