Manufacturing: Hydraulic Jacks
Manufacturing: Hydraulic Jacks
We manufacture heavy-duty hydraulic jacks with lifting capacities ranging from 5 to 500 metric tons. We engineer heavy lifting solutions for machinery positioning, structural prestressing, load proof-testing and specialized industrial tasks.
Technical Specifications
Maximum Working Pressure:
Up to 50 MPa (500 bar)
Number of Telescopic Stages:
1 to 4 stages
Design Types:
Plunger (single-acting) piston (double-acting) and multi-stage telescopic
Operational Execution:
Standard industrial low-temperature (-40 °C) and marine/corrosion-resistant
Available with integrated linear displacement (stroke) sensors, counter-balance and load-holding lock valves and electric or manual pump integration.

Key Engineering Advantages
Custom Calculation
Buckling resistance, stroke stability and fatigue life calculated specifically for actual load conditions.
High-Strength Alloys
Piston rods manufactured from hardened alloy steel 40X (42CrMo4 equivalent) with micro-crack-free hard chrome plating. Seamless drawn, heavy-wall barrel tubing.
100% Quality Proof Testing
Every jack is proof-tested on our test frame at 125% of its rated capacity. We check for seal leakage and ensure smooth, controlled movement under the specified off-center loading conditions.
Full Technical Documentation
Equipment passport with recorded test curves, material test certificates and 12-month factory warranty.

Frequently Asked Questions
What is the difference between a hydraulic cylinder and a hydraulic jack?
A hydraulic jack is traditionally a single-acting high-tonnage cylinder optimized specifically for vertical lifting and static load holding under extreme pressures. We manufacture both classic single-acting plunger jacks and universal double-acting heavy cylinders.
Can the hydraulic power pack be supplied together with the jack?
Yes we provide complete sets including electric gasoline or manual hand pumps high-pressure hose assemblies and multi-port control manifolds.
Do you repair existing worn jacks?
Yes we service and remanufacture jacks of all makes and models.
