The large electric shovels, weighing over 860 tons, with payload capacities over 120 tons, remove overburden and minerals including coal, and load it into haul trucks at large open pit strip mines around the world. The couplings are installed on drive motors that operate the shovel’s propulsion, crowd, swing, and dipper/bucket hoist winches.
Ameridrive SF (Flange Type) spindles feature special molded high angle lip type seals, custom gear tooth geometry, and gear teeth that are heat treated to provide higher torque ratings. The AISI-1045 induction hardened spindles provide up to 6° of misalignment. The 13.62-in. and 16.56-in. diameter couplings are the most common sizes used with a torque capacity of 1,621,400 in.lbs.
Ameridrive gear spindles continue to provide exceptionally reliable performance for decades in rope shovels worldwide.
