Hydraulic jacks with hydraulic hand pumps, bulk order, boxed delivery

Jacks and oil pumps are two commonly used lifting tools, jacks mainly play a load-bearing role, while the oil pump is to provide hydraulic power source, in the completion of the fixed support or lifting work, you need to jacks and oil pumps with the use of. The principle of the jack is to pressurise the internal liquid to produce deformation, so as to achieve the role of lifting and supporting. And the oil pump is through mechanical compression, hydraulic or electric drive mode, the formation of a certain pressure will be delivered to the jack internal liquid. Method of use: 1. Place the jack on the position to be supported or lifted, and make sure that the jack is perpendicular to the working surface. 2. Place the oil pump on a smooth ground, connect the oil pump with the jack, and seal the connection. Make sure the connection is secure to avoid leakage. 3. Switch on the power supply of the pump or start the hydraulic pump to generate a certain pressure. 4. After confirming that the pressure of the oil pump meets the requirements, start to control the work of the oil pump, and transfer the liquid to the jack through the oil pipe, so that it can lift or fix the workpiece. 5. In the process of using, pay attention to the action should be slow and steady, avoid sudden pressurisation or acceleration, resulting in overloading or damaging the parts.

Product Recommendation

SL-RTC super slim type cylinder/ super slim type jack

SL-RTC Super Thin Hydraulic Jack

Has an ultra-low closing height and 5-10mm stroke for precise adjustment and lifting in very narrow workspaces. Adoption of high pressure design (150Mpa) makes the external dimension smaller, suitable for more narrow space. Single acting design with load return.

SL-TB hydraulic bolt tensioner

SL-TB Hydraulic Bolt Tensioner

Bolt tensioner generally consists of hydraulic pump, high pressure hose, pressure gauge and tension body. Among them, the hydraulic pump is the power source, the pressure gauge reflects the output pressure of the pump, the high-pressure hose connects the hydraulic pump and the stretching body. Tension body is to achieve the bolt stretching of the executive element. Mainly by the piston cylinder, piston, support bridge and stretching nut composition.When working, the high-pressure oil output from the power source is transported to the piston cylinder through the high-pressure hose, and the piston in the piston cylinder moves up under the pressure, driving the stretching nut to move upwards. The stretching nut is threaded with the working bolt, so as to elongate the working bolt, so that the bolt elongation reaches the required deformation, the deformation is controlled within the range of elastic deformation, and then carry out pre-tensioning or dismantling operations, and finally make the working bolt return to its original shape by means of hydraulic or mechanical return to the original shape to complete the operation.

SL-HT Wind power bolt tensioner

SL-HT Wind Turbine Tensioners

Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At SOLY, we’ve been building hydraulic tensioners and nuts since 2007.

The SL-HT tensioners are a purpose designed range of tools to suit all applications in wind turbine manufacturing and operations. These tensioners offer a  reliable and consistent method of simultaneously tensioning multiple joints and have an integrated fail safe design to enhance workplace safety.

Designed for special needs such as small space, large load, long life and fast speed, meeting ENISO898:1999 standards;
