Hydraulic Pressure Tool 44

Application

The pressure tool is usually used to loosen tightly fitted parts in conjunction with mechanical extractors.

Operation

The hydraulic pressure tool generates an axial force of 80 or 150 kN, respectively, thus making the job considerably easier. The spindle thread of the mechanical extractor is not unduly stressed as the main extraction force acts on static thread flanks.

The pressure tool 44.150 features a hydraulic resetting mechanism, i.e. when the thrust bolt is reversed the hydraulic system automatically returns to its normal position. The hydraulic pressure tool is applied between shaft end and extractor spindle. Then the spindle is applied.

The hydraulic system is actuated by screwing in the thrust bolt. The axial force generated will loosen the part. The part can then be extracted in the usual manner with the mechanical spindle.

For safety reasons, the minimum spindle diameter and the maximum torque (see table) must be observed.
