LONGLOOD RR Series cylinders are widely used in:
Available up to 520 tons, providing powerful hydraulic performance for large-scale applications.
Long stroke options up to 1219 mm provide greater flexibility for lifting and positioning tasks.
Double-acting operation allows controlled movement during both extension and retraction.
Designed for demanding industrial environments with durable materials and protective finishes.
Multiple mounting options simplify integration into different hydraulic systems.
Built-in safety features help protect both equipment and operators.
For safe operation:
A double acting hydraulic cylinder uses hydraulic pressure to extend and retract the piston, providing controlled movement in both directions.
The LONGLOOD RR Series provides:
Capacity: 10–520 tons
Stroke: 57–1219 mm
Long stroke cylinders provide greater movement distance, making them ideal for:
The maximum operating pressure is:
700 bar (10,000 psi)
A single acting cylinder uses hydraulic pressure in one direction and returns by spring or load force, while a double acting cylinder uses hydraulic pressure for both extension and retraction.
Removable hardened saddles protect the cylinder plunger during lifting and pressing operations and allow easy replacement when needed.
CR-400 couplers provide quick and secure hydraulic connections between the cylinder and hydraulic pump system.
