Single-acting thin-type hydraulic jack
Category: Jack
Details
Product Introduction: Single-Acting Thin-Type Hydraulic Jack
The Single-Acting Thin-Type Hydraulic Jack is a compact and powerful lifting device specifically engineered for use in confined spaces and low-clearance applications. Designed for ease of use, high performance, and portability, this jack is ideal for industrial maintenance, machinery positioning, steel structure adjustment, and construction site operations.
The standout feature of this jack is its ultra-low profile design. With a closed height as low as 30mm in some models, it can be inserted into tight spaces where conventional jacks cannot fit, making it a critical tool for emergency lifting and field repair work.
Built for single-acting operation, it uses hydraulic pressure to lift the load, while the piston retracts automatically with spring return. This makes it highly efficient for repetitive tasks and short lifting cycles, helping to increase productivity and reduce labor intensity.
Constructed from high-strength alloy steel, the tool offers exceptional durability and resistance to high pressure, wear, and impact. The surface is finished with anti-corrosive treatments to ensure reliable operation in harsh and dirty environments such as construction sites, shipyards, or mining fields.
This jack is compatible with standard hydraulic hand pumps, electric pumps, and air-operated pumps working at 700 bar / 10,000 PSI. Its threaded quick-connect coupling makes it easy to integrate into existing hydraulic systems or multi-jack setups for synchronous lifting.
To further enhance its utility, it is available in capacities ranging from 5 tons to 150 tons, with stroke lengths from 10 mm to 50 mm, depending on the model. Despite its small size, it delivers a strong lifting force with minimal effort.
In terms of safety, the unit features a grooved piston head to prevent load slippage, and many models include an overload protection system to avoid damage under excessive pressure. Optional carrying handles or magnetic bases are also available for easier transport and stability during operation.
Professionals across industries choose this solution for its compact size, powerful output, and quick return operation. Whether used in mechanical repair shops, mobile equipment servicing, or structural alignment, it delivers consistent and dependable performance.
It is also ideal for use in tandem with support blocks, jacking pads, and adjustable shims for precise leveling. Its low height makes it especially useful in rescue operations, mold installation, die separation, and machinery base lifting.
If you're looking for a compact, safe, and high-efficiency lifting solution, this hydraulic jack is your top choice. Backed by rigorous testing and available in a wide range of specifications, it delivers the power you need—right where you need it.
In conclusion, this is not just a lifting tool—it's a high-performance solution built for precision, speed, and space-limited environments. Trust it to handle your toughest lifting challenges with ease and reliability.

30 tons of thin jack one tow four configuration scheme
Electric pump, hydraulic distribution valve, hydraulic oil pipe 5 pieces.
20 sets of 50 tons of thin jack synchronous jacking configuration scheme
Multiple jack synchronous jacking can choose the pulse width control synchronous jacking system to realize the synchronous jacking of each jacking point with the error range of 0.5mm, which is mostly used for the synchronous jacking project of bridge construction and the synchronous jacking of large equipment maintenance.
Product recommendation
For a larger tonnage overhead lift (300 tons, 500 tons or higher tonnage), please choose our electric hydraulic jack.
If you need to wear thread self-locking function, support for a long time support, please choose our self-locking jack.
If you need a lower body height and adapt to a lower placement space, please choose our ultra-thin jack.
