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.
