PDTA Square Drive Hydraulic Torque Wrench
Hydraulic torque gun manufacturer and supplier
Hydraulic torque gun is one kind of power tool designed to exert torque on a faster to achieve proper tightening or loosening of a connection through the use of hydraulics. Hydraulic torque wrench is applied to the nut either directly or in conjunction with an impact socket. Hydraulic torque wrenches apply a predetermined, controlled amount of torque to a properly lubricated fastener.
Application field:
Hydraulic wrenches are widely used. Hydraulic torque wrench is an important tool for the installation and disassembly of large-sized bolts in the construction, maintenance and repair of shipbuilding, petrochemical, wind power, hydropower, thermoelectric, mining, machinery, steel mills, rubber, pipelines and other industries. There is no substitute for other tools, which is not only convenient to use, but also provides very accurate torque, and the torque repetition
accuracy reaches about ±3 %.

Model choose tips:
The selection of hydraulic wrench is determined by bolt size, torque requirements and space range.
- Bolt size, firstly, need to confirm the specification of the bolt, metric or imperial, and the bolt size. If including many different size of nuts, we suggest choose different model of hydraulic torque wrench according to nuts size and torque force.
- The specification and strength grade of bolts are the most critical parameters of hydraulic torque wrench selection.
- Space position of bolts and nuts, if the space permitted, PDTA square drive hydraulic torque wrench and PDCT low profile hydraulic torque wrench are suitable, if the space is narrow, we suggest to adopt the PDCT series of wrench.
- 1 ) One model of hydraulic wrench can only solve several similar bolts, usually with 1 - 10 impact sockets;
2 ) it is best for qualified manufacturers to use an electric pump with two wrench heads, and use it diagonally, which can improve efficiency and torque more accurately.
3 ) hydraulic wrenches must be used by special personnel, kept by special personnel and often maintained, such as oil change and cleaning.
