Hydraulic transmission, static torque stepless adjustment tightening torque; Accurate and constant output torque ensures accurate fastening of the sleeper nut;

 High speed tightening at low torque, increased resistance torque, automatic

Switch to high torque low speed;

 Torque visual display, night lighting (using LED hair

Photodiode), convenient and efficient;

 The machine is powered by gasoline engine and carried out by hydraulic system

Drive and precise control, is the railway new and old lines, special

Especially the high-speed railway line is very suitable for construction and maintenance

Trade machinery;

 The machine hydraulic system adopts advanced technical principle,

Achieves high speed tightening when the torque is small, and increases when the drag torque

Large to a certain automatic switch to large torque low speed, so that the liquid

The pressure wrench can output more tightening torque;

 The mechanical part of the hydraulic wrench wear will not be affected

Hydraulic wrench accurate tightening torque output and display;

 double head wrench, high efficiency, operation and adjustment

The section is very convenient and light in weight. The nut sleeve adopts 10,000

The floating mode makes it easier to insert or detangle the sleeper

Mother, sleeve stroke is convenient to change;

 This machine is suitable for the construction and maintenance of various specifications sleeper nuts and bolts (including rectangular bolts) of various types of railway rail.
