Cruncher U-45JR

The crushing cruncher

Compared to NPK^® G-series, the new U-cruncher shows important differences: one big center tooth. Because of the center tooth, all forces are concentrated to one point, which makes the U-cruncher act also as a crusher. Besides that, the new model has a relatively longer cutter for cutting light steel structures, besides rebar. Another advantage is the 360 degrees hydraulic rotation, allowing great manoeuvrability. The U-cruncher is an ideal tool for crushing and cutting walls, floors and light steel structures, such as apartments, reinforced walls, etc.

High speed – extreme power

Like all NPK^® crushers and crunchers, the U-model has the standard integrated booster system, a unique feature designed by NPK^®. This booster system automatically activates whenever the jaws meet resistance. This pressure intensifier system has a relatively low oil flow and produces faster cycle times and more crushing strength. Additionally, other excavators functions remain uninfluenced. The integral booster allows a compact body design, reduces the total weight of the attachment and affords ease of maintenance.
