High Accuracy Hydraulic Torque Tools For Installation And Disassembly Bolts

Bolt solution specialist , Whole set hydraulic torque wrench supplier

Hydraulic torque wrench 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 %.

The selection of hydraulic wrench is determined by bolt size, torque requirements and space range.

1. 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.
2. The specification and strength grade of bolts are the most critical parameters of hydraulic torque wrench selection.
3. 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.
4. 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.
    

Construction site:

Characters:

1. Hydraulic torque wrench, made of ultra-high strength aluminum-titanium alloy, thin design, double - acting, high speed and big corner;
2. clamping type, interchangeable plug - ins, no need of special tools, torque repetition accuracy as high as ±3%;
3, 360°×360° and 180°X360° rotary hose connectors, which are suitable for compact occasions and convenient for positioning.
4, wrench strength design is sufficient, the overall reaction arm, fewer movable parts, durable and reliable;
5. Can work with metric and imperial hexagonal insert socket, which can realize that one power head is equipped with multiple insert socket for simultaneous use;
6. Most of them are used in special working conditions: double nuts, bolts are too close to the equipment wall, bolts are too long, nut spacing is too small, etc.

7. If needed, can work with our back-up wrench, more convenient.
