TorcStark hydraulic wrenches are all made of high-strength titanium alloy material, with reliable quality and long service life. The main body of the wrench is machined into one piece, which is lighter in weight and more durable.

hydraulic wrench adopts precise ratchet transmission, and the torque output is of high precision. The maximum working pressure can reach 70Mpa, and it is equipped with a 360°x 180° rotating oil pipe joint, which is easy to use and has good adaptability. The direct-push drive shaft can realize the rapid tightening or disassembly of bolts, saving time and labor.

Bolt Tensioners

TorcStark has 7 types of bolt tensioners and 2 types of hydraulic nuts.

In the petrochemical industry, bolt tensioners are one of the most commonly used bolting tools. TorcStark tensioners are compact in design, small in size, light in weight, and easy to maintain. Even the replacement of the connecting rod can be done in just a few simple steps. Among them, ZLD and SJD series tensioners are specially designed for bridge engineering projects. The bridge special tensioner is light in weight, high in working pressure and easy to use. The surface of the product is treated with anti-corrosion and anti-oxidation, which is one of the best tools for bridge construction and maintenance. MSD products are specially designed and manufactured for the connection of wind turbines and have strong adaptability to various brands of wind turbines and bolts in different positions. For pipe openings and valves, leakage prevention can be achieved with our hydraulic nuts.

Hydraulic Wrench/Tensioner Pump

There are 10 hydraulic pumps in torcStark: 7 electric hydraulic pumps, 1 pneumatic hydraulic pump, 1 gasoline engine driven hydraulic pump, and 1 manual pump.

Torcstark hydraulic pumps are made of aluminum-titanium alloy, which is light in weight and easy to carry. It is fast at light loads and more precise in speed and bolt tightening at heavy loads. Among them, the intelligent hydraulic pump adopts a one-piece operation: only need to input the pulling force and wait for it to complete the work. The hand pump has a simple structure design and is easy to carry. Its built-in precision high and low-pressure switching valve has stable and reliable performance.

Synchronized Jacking System

Torcstark has a total of 6 synchronous jacking systems: some are professionally used for hydraulic cylinder control, and some are mainly suitable for beam-type heavy-duty fields such as hull welding and railway bridges.

The TorcStark synchronous jacking system can control up to 99 points with an accuracy of up to 0.5mm. It is equipped with a double plunger pump system, which makes the lifting smooth, and can perform real-time detection of displacement and pressure. It is also perfectly suitable for beam-type heavy-duty conditions such as hull welding and railway bridges. The super large carrying capacity ranges from 100 tons to 6000 tons and has the function of data storage, simple operation, and a high degree of automation.
