JENZ has extended its range of mobile coarse chipper products: on the HEM 821 DQ Cobra+ the driver’s cab can be run up and down and also rotated. That oves the chipper driver a better overview. Apart from that, he doesn’t need to change his seating position. Even if the driver’s cab is raised and rotated, the machine can manoeuvre with full towing force available from the carrier vehicle up to 8 km/h, which is particularly advantageous during practical use. Despite its 33 t live weight, the HEM 821 DQ is also easy to drive off-road thanks to its two driven axles.Manoeuvrability is hard to beat thanks to the new steering axle.
