Flat self-locking hydraulic jacks are ideal for applications that require long-term lifting and support. The piston rod is threaded for mechanical locking.
● Max. Working pressure: 70MPa
● Single acting design, load return
● Suitable for lifting work which requires plunger extends for a long time
● Mechanical nut bearing with the load, so it can tighten
● the mechanical nut at any position in the stroke to make sure the operation safety
● Ultra-thin design, suitable for highly limited space
● Lateral load supported is equivalent 3% load capacity
● Cylinder equipped with ball type saddle to adapt component rough

Self-Locking Jack with P-80 Manual Hydraulic Pump
● Operated manually, this configuration is perfect for locations without a power supply.

Self-Locking Jack with Electric Pump
● This setup quickly lifts the cylinder, saving time and labor.

24-Unit 50-ton Self-Locking Jack Synchronous Lifting System
● For synchronous lifting of multiple jacks, you can choose a pulse width controlled synchronous lifting system. This system ensures all lifting points are raised simultaneously with a maximum error of ≤0.5mm. It's often used for synchronous lifting projects in bridge construction and for the maintenance of large-scale equipment.

● For a single oil circuit with spring return, please select our separate-type jacks.

● For a lower body height and a larger working stroke, please consider our low profile hydraulic cylinders

● For higher lifting capacities (300 tons, 500 tons, or more), please choose our electric hydraulic jacks.
