Lock Nut & Long Stroke Cylinders
Single-acting and double-acting mechanical lock nut cylinders and long-stroke double-acting push-pull rams.
HDC Series D/A General Purpose Cylinders
The HDC-Series is a heavy-duty, double-acting general-purpose hydraulic cylinder engineered for high-cycle industrial operations, bridge lifting, hydraulic presses, and structural construction maintenance. Powered by 700 Bar (10,000 PSI) working pressure across 10 to 300 Metric Ton capacities, double-acting hydraulic return delivers rapid, controlled retraction under full tonnage, while an integrated retract-side safety relief valve prevents accidental circuit over-pressurization.
HSC-LP Series Low-Height Pancake Lock-Nut Cylinders
The HSC-LP-Series is a single-acting, load-return low-height pancake lock-nut hydraulic cylinder engineered for sustained mechanical load holding in confined vertical clearances. Rated for 700 Bar (10,000 PSI) working pressure across 60 to 520 Metric Ton capacities, the mechanical lock nut threads down to physically support the load, allowing hydraulic pressure to be completely released. Standard equipped with a tilt saddle and overstroke overflow port for safe operation in bridge lifting and heavy construction maintenance.
HSC-LN Series S/A Lock Nut Cylinders
Single-acting load-return lock nut hydraulic cylinders rated for 700 Bar (10,000 PSI), engineered for sustained mechanical load holding, bridge lifting, and structural maintenance across 50 to 1,000 Ton capacities.
HSC-LNH Series S/A High-Tonnage Lock Nut Cylinders
Single-acting load-return high-tonnage lock nut hydraulic cylinders rated for 700 Bar (10,000 PSI), engineered for sustained mechanical load holding, bridge deck jacking, and heavy structural leveling across 50 to 1,000 Ton capacities.
HDC-LN Series D/A Lock Nut Cylinders
Double-acting hydraulic-return lock nut hydraulic cylinders rated for 700 Bar (10,000 PSI), engineered for sustained mechanical load holding, bridge repositioning, and precision machinery leveling across 50 to 300 Ton capacities.
