Pump Drive for Mining Shovel

Cotta supplies a pump drive to a customer that was in need of units that would be used for a hydraulic crowd in a mining shovel application.   Mining shovels are used to excavate large quantities of soil and rock fragments in surface or strip mining operations.  Classic mining shovels were designed with a winch and cable that operates the bucket up.  The problem with that type of design, is that the cables run over the pulleys in the same spot every day. After so many hours of use, the cables wear out, which results in the machine having to be shut down for at least a day to get the cables restrung. Cotta’s engineering team designed a pump drive for the application, and by using a hydraulic cylinder this eliminated the need for a cable drive.  This technology has saved the customer time and money, as it allows the operators to run the machines for a number of years before service work is required, versus being down once a month to restring the cables.
