If you’re designing or maintaining hydraulic systems for mining applications, IC-Fluid Power can help identify the right components for your system requirements.


Mining and tunneling equipment utilizes many different hydraulic components that must work under extreme loads, abrasive environments, and continuous operation. Rotary actuators, pressure intensifiers, check valves, butterfly valves, and test points are used in tandem on mining equipment. Some examples on common uses are…

Rotary actuators control precise boom and attachment positioning on drill rigs and excavators. Pressure intensifiers boost system pressure for brake circuits, cylinders, and other tools without requiring a larger pump for the whole system. Butterfly valves and check valves protect mobile machinery from fluid loss and back flow. Test points facilitate easy pressure diagnostics without lengthy system downtime.

Hydraulic rotary actuators deliver high torque output and precise rotary motion in an enclosed, compact housing. These design features make them particularly well suited for heavy-duty mining and drill rig applications, such as boom positioning and rotation, as well as machine steering. Their size allows them to fit into small, mobile machinery, while their enclosed design allows them to function in harsh environments with dust and debris.

Helical spline designs offered by IC-Fluid Power are capable of standard torque up to 750,000 in-lb (85,000 Nm) at operating pressures up to 3,625 psi, with custom configurations capable of reaching 2,200,000 in-lb (250,000 Nm). Standard rotation angles range from 90° to 360°, with up to 720° available as a custom option for applications requiring extended rotation range.

Yes, by not needing to upgrade your pump or fully redesign your system to provide a local pressure boost in one area.

Pressure intensifiers enable systems to reach ultra-high output pressures (up to 58,000 psi / 4,000 bar) from an existing hydraulic circuit. This eliminates the need to upgrade pumps or invest in redesigning the entire system to handle high-pressure capabilities. With pressure ratios up to 16:1 and input pressures up to 2,900 psi (200 bar), they are used to intensify pressure to brake circuits, pressurize support cylinders on booms and masts, and boost clamping and cutting tool performance. This makes them a cost-effective solution for applications where local, task-specific high pressure is needed in a standard hydraulic system.
