Hydraulic amplifier has the most powerful energy, in the rescue and rescue machinery and equipment expansion, tear and pull performance application in people's survival is very general, so what kind of temperament is this type of goods? Understand it all the way: can be connected with the drive chain to do the traction belt work. Multi-function jack brand off time is short, the progress of disaster resistance is accelerated. The 650MM expanded section is capable of opening, opening plates and optional rescue modes.

The actual operation on the left side of the handle is simple, and a part of the protective shell is moved to ensure the quietness of the manipulator. Double hydraulic lock valve and automatic return position organization, gearbox jack brand control safety factor, with self-locking performance, can be carried out at each detailed address, no rebound.

In addition, it can be used for long time load safety practical operation, high toughness light carbon steel, light weight, big swelling force; Can be used to move and lift obstacles, front jack brand scratched cracking and expansion mode of deformation of metal components, torn thick steel plate body. Short opening and closing time; Double hydraulic lock and automatic calibration pressure regulating valve organization with self-locking performance, high operating safety factor, can be carried out at each detailed address without retracting.

The characteristics of expander in hydraulic jack are described
