Large Hydraulic Direct Drives in Mining Operations
While both electromechanical and hydraulic options described here provide reasonably acceptable performance for driving high-load material handling systems, large hydraulic radial direct-drive motors offer unique advantages worth considering for applications calling for high-torque, low-speed operation. The hydraulic power unit supplying the radial piston motor consists of a fixed-speed electric motor driving a variable displacement axial piston pump, intelligent pump controller and fluid monitoring system, and hydraulic fluid reservoir.\n This can be two motors driving a single axis, or four motors driving two axes (at both ends of a conveyor, for example); this is an easier way to ensure that both motors carry a common load, since the hydraulics are all part of the same closed-loop circuit sharing the load naturally.
