Mining OEM Achieves 32% Lower Annual Costs by Simplifying an Electric Rope Shovel Design
Mining Equipment Manufacturer Realizes $124,080 in Annual Cost Savings with Rexnord Planetgear
A mining equipment manufacturer sought to upgrade its electric rope shovel because the existing dipper trip drum design took up significant space and was causing persistent field issues—dipper door jams and motor breaker trips.
The experts at Regal Rexnord offered a solution that allowed the manufacturer to move from two variable-speed DC motors to one Rexnord Planetgear Inline Gear Drive. This solution not only shrunk the space envelope but increased available torque and improved overhung load / thrust capacity to handle high-impact loads.
