Considerations for hydraulic bolt tensioners

1) a type of hydraulic bolt tensioners, can only solve several similar bolt sleeve with 3-4;
2) manufacturers have a condition it is best to first use of an electric pump with two wrenches, diagonal, you can improve efficiency, torque is more accurate, one for four costs are too high;
3) flange alignment must be someone special custody, regular maintenance, such as oil changes, cleaning and so on;
4) bolt torque standard should refer to national standards, national standards are in line with China's national conditions.

Characteristics of hydraulic bolt tensioners

Using ultra hydraulic bolt tensioners strength light metal, thin design, double-acting, high-speed, large turning angle
Card-Exchange plugin, do not need special tools, torque repeatability up to ± 3%
360 ° x360 ° and 180 ° X360 ° rotating hose connectors, suitable for compact and convenient locationtorque wrench calibration tool strength design, the overall reaction arm, less moving parts, durable, reliable
Scalable metric, Hexagon Plug and socket, can achieve a power head is equipped with multiple plugins using
Most were used for special working conditions: double nuts, bolts and equipment too close to the wall, spacing is too small for long bolts, nuts, and more!
