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-STC ultra-low thin cylinder jack
SL-STC series ultra-low profile jacks are designed with ultra-high pressure (70M Pa) for smaller appearance. Suitable for more narrow space . Single acting design, load return. Adopting copper welding process on the piston part is not easy to pull the cylinder, and it can be used repeatedly to create more efficiency and save cost for customers.
SL-EW straight handle digital display electric torque wrench
SL-EW direct handle digital display electric torque wrench has double overload protection function, electronic torque control system and torque overload clutch design, effectively improve the service life of transmission components and carbon brush; The service life of the carbon brush is more than 8 times the service life of other similar brand products, and the motor motor speed is controlled by the intelligent torque control of the single chip microcomputer, making the service life of the carbon brush and wrench longer.
SL-ZCD Pile Load Tesing Hydraulic Jack
SOLY manufactures and supplies a full range of hydraulic jacks for pile load testing operations. Our standard pile load testing jacks’ capacity range from 50 ton to 1000 ton, and we can customize hydraulic jacks up to 2000 tons under the customer’s requirement.
SL-GT Hydraulic Bolt Tensioner
Bolt tensioner is a special tool for tightening or dismantling bolts using hydraulic principle.
By stretching the bolt, it is elongated within the elastic deformation zone and the bolt diameter is slightly deformed so that the nut can be easily loosened or tightened. In addition, it can be used as a device for applying axial force to hydraulic interference connections for top pressure installation.
The operating principle of the bolt tensioner is based on the tensile strength, yield coefficient and elongation of the material. When working, the power source (such as hydraulic pump) output of high-pressure oil through the high-pressure hose delivery to the tensioner’s piston cylinder, under the pressure of the piston in the piston cylinder piston upward, driven by the stretching nut upward movement. The stretching nut is threaded with the working bolt, thus elongating the working bolt, so that the bolt elongation reaches the required amount of deformation (deformation control in the elastic deformation range). Then pre-tensioning or dismantling is carried out, and finally the working bolt is returned to its original shape by means of hydraulic or mechanical return to its original position to complete the operation.
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.
