Cruncher U-21JR

The crushing cruncher

Compared to NPK®s G-series, the new U-21JR cruncher shows important differences: one big center tooth and a center cutter. 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 center cutter for cutting light steel structures, besides rebar. Another advantage is the 360 degrees hydraulic rotation, allowing great manoeuvrability. Together with the center tooth and cutter the U-21JR 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

As 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.

Advantages

• Standard integrated booster system that automatically activates when the jaws meet resistance.
• Center tooth: more crushing power.
• Hydraulic rotation 360° for precise positioning.
• High productivity and extreme power.
• Standard center cutter for rebar and light steel structures.
• No additional pressure reduction is required in the hydraulic system.
