● Single acting, load return, mechanical lock nut for for safe mechanical load holding-over a long period of time;

● Bearing load for a long time after pressure relief;

● Visible remarks to warn operator when stroke reaches the limit;

● Stroke equipped with overflow port prevents piston over extended;

● Optional special synthetic coating for improved corrosion resistance and lower friction for smoother operation;

● Allowable partial load reaches 5% capacity of hydraulic cylinder;

● NPT3/8 quick couplers and threa protector included.

Multi-Unit Synchronous Lifting System

● For the 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 is commonly 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.
