The main cylinder is equipped with a hydraulic booster. When the jaws meet resistance, the hydraulic booster will be automatically activated. (* SV-series two boosters)

The pressure intensifier system has a relatively low oil flow; which produces fast cycle times and more crushing strength when compared to competitive crushers without booster system. Additionally, other excavator`s fun­ctions remain uninfluenced by this system. The integral booster reduces the total weight of the attachment, which allows a compact body design and affords ease of maintenance.

The complete range of X-series crushers will be available with carbide sprayed coating tooth design.

The complete range of S-series crushers will be available with the new NPK® C-type arm.

The complete range of SV-series crushers will be available with the new NPK® C-type arm.

The new shape of the arms of the NPK® C-type crusher results in the improvement of the crushing ability and durability of the arms.

The NPK Powerbooster can be explained in 4 steps, as described above. As soon as the jaws meet resistance the extra speed is changed to extra power. Without concrete in the jaw, the booster creates more speed.
