The Detachable Hydraulic Jack is a versatile and practical lifting tool widely used in industrial and construction sectors. Its key feature is the separation of the power source—the hydraulic pump—and the lifting component—the hydraulic cylinder—connected via a high-pressure oil hose. This design allows flexible operation, easier maintenance, and safer handling in complex working environments.
With its robust build and reliable hydraulic performance, the detachable hydraulic jack is suitable for applications demanding high load capacity and precise control.
The detachable hydraulic jack serves a broad range of applications including but not limited to:
① Bridge and Building Lifting
Synchronous lifting of entire bridge decks for bearing replacement
Horizontal translation and repositioning of large buildings
Precision elevation in structural repairs and reinforcement
② Heavy Equipment Installation
Installation and precise positioning of heavy industrial machinery
Maintenance and relocation tasks requiring controlled lifting in confined spaces
③ Rescue Operations
Lifting and prying open deformed vehicle structures after accidents
Emergency rescue scenarios requiring rapid, reliable hydraulic lifting
④ Multi-Industry Usage
Widely adopted in foundation testing, traffic infrastructure, railways, subways, bridge construction, building projects, and mining industries
Ideal for any operation requiring strong hydraulic lifting with flexible pump-cylinder arrangement
① Convenient Installation
All models feature screw holes at the base, allowing secure and stable mounting to work surfaces or equipment, enhancing operational safety.
② Safety Return Valve in Hydraulic Cylinder
The cylinders incorporate a return oil safety valve designed to prevent damage caused by sudden overpressure, ensuring durability and user protection.
③ High-Hardness Removable Grooved Pads
Equipped with anti-slip grooved pads that can be removed as needed, providing extra stability and safety during lifting operations.
④ Wear-Resistant and Corrosion-Resistant Components
The main shaft and internal surfaces of the jack are treated with hard chrome plating, significantly enhancing wear resistance and corrosion protection. Dust seals reduce contamination and prolong service life.

Flexible and convenient pump-cylinder separation allows easy positioning and safer operation.
Robust construction with advanced surface treatments ensures long-lasting durability.
Safety features including return oil valves and anti-slip pads enhance operational security.
Wide range of models from 50 to 3000 tons capacity cover diverse lifting needs.
Suitable for demanding industrial, construction, and rescue environments worldwide.
The Single-Acting Thin Self-Locking Hydraulic Jack is a compact lifting tool designed specifically for applications with limited vertical space. Featuring a low-profile hydraulic cylinder, it provides strong lifting force in confined environments where traditional jacks cannot operate.
After the jack reaches the required lifting height, its unique mechanical self-locking structure automatically engages. Even if hydraulic pressure is lost, the jack can securely support the load, significantly enhancing operational safety.
This self-locking mechanism makes it suitable for demanding industrial, construction, and rescue applications where stability and reliability are critical.
In modern infrastructure projects, precision and safety are paramount. Whether you are constructing a new bridge or performing major repairs on an existing structure, the lifting process of large and heavy components requires specialized equipment designed for synchronization, control, and safety. Our Synchronous Lifting Hydraulic System is engineered to meet these demanding needs, offering a reliable and efficient solution for bridge lifting projects. This system is designed to provide controlled, synchronized lifting at multiple points, ensuring that the structure is lifted evenly and safely, preventing any potential damage during the operation.
The Ultra-High Pressure Manual Hydraulic Pump is a hand-operated device capable of generating extremely high hydraulic pressure ranging from 100 MPa to 400 MPa. Designed for environments where electricity is unavailable, restricted, or hazardous—such as offshore platforms, explosive zones, and field maintenance—this pump converts manual mechanical force into stable high-pressure hydraulic energy.
It serves as a reliable power source for a wide range of high-pressure hydraulic tools and industrial applications.
