Crushers

More power – more production

The main cylinder is equipped with a hydraulic booster. When the jaws meet resistance, the hydraulic booster will be automatically activated.

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 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.
