Typical Applications

•  Advancing Ram •  Excavators •  Shield Ram
•  Base Lift Ram •  Longwall Roof Support Systems •  Shuttle Cars
•  Crushing Equipment •  Mining Haul Trucks •  Surface Mining Equipment
•  Cutting Machines •  Rock-Breaker Attachments •  Tunnelling Machines
•  Double Telescopic Legs •  Roof Bolters •  Underground Vehicles
•  Drilling Equipment •  Scoop Trams •  Wash Plants
•  Drilling Machines •  Shearers

Technological advancements continue to push the limits of surface and underground mining. From increasing leg bore cylinder diameters and cutting heights, to maximizing the rate at which longwall shearers operate, productivity and efficiency are paramount to minimizing downtime and unscheduled maintenance. Densely packed coal and potash formations and cavity roof loads place extreme performance requirements on shearers, longwall roof support systems and related equipment.

Operating requirements and serviceduty dictate the design of hydraulic systems and cylinders in the mining space. Fluid compatibility, lubricity, and contamination are all critical concerns for the optimal performance of mining equipment and application. The components within hydraulic systems must be built to ensure extended life cycles under extreme conditions.

Timing and delivery are critical factors to successful operations. At Hallite Seals, we have decades of experience in designing and manufacturing polymer components for a broad range of activities in the mining industry. We work with you to ensure you mitigate your risk, protect your personnel, your assets, and the environment.
