Open-pit dump body
Heavy-tonnage aggregate and ore dumping; high force, fatigue life critical.
Bore 150-320 mm · Stroke 4,000-7,000 mm · Telescopic/double-acting
Application sector
Mining Applications
Heavy-duty hydraulic cylinders for mining equipment: open-pit dump bodies, crushers, conveyor tensioning and mine support. Fatigue resistance critical under abrasive dust, impact loads and high tonnage.
Typical applications
Crusher & screening
Crusher jaw open-close, screening adjustment cylinders; impact and wear resistance.
Bore 120-250 mm · Stroke 500-2,000 mm · Double-acting
Conveyor tensioning & support
Belt tensioning cylinders, underground support and roof-support applications.
Bore 100-200 mm · Stroke 800-3,000 mm · Load-holding valve
OEM-compatible replacement cylinders
