YLB-760 Hydraulic Precision Bolt Wrench
性能及特點
Suitable for all kinds of rail elastic fastening nuts of the elastic operation；
For high speed railway and new line, the output torque is constant.；
Spindle speed automatic switching；
System through the shunt valve control, low torque, rapid tightening, the resistance torque increases to a certain value when the automatic switching to the low speed maximum torque output, ensuring the accurate fastening operation；
Mechanical wear will not affect the accuracy of the torque output and display；
Hydraulic oil capacity is only 4 liters, the new design of the annular oil radiator to ensure the best operating temperature of the system；
Hydraulic oil capacity is only 4 liters, the new design of the annular oil radiator to ensure the best operating temperature of the system.；
The torque setting applies only to the bolt fastening operation and the system automatically switches to the maximum torque state when the operation is removed.；
Sleeve head with operating light；
