  • Cooling – Large-sized cooling unit
  • Hydraulic tank – 765L
  • Steering – Proportional, hydraulically and precise control of the hydraulic functions, 2 servo joysticks for operating movements, additional functions through switches and foot pedals
  • Safety valves for all hydraulic circuits
  • High efficiency through well designed hydroulic valves and lines
  • Pressure accumulator for lowering of attachments when engine turned off
  • Central pressure test ports
  • Safety valve for boom cylinder
  • Safety valve for telescopic boom cylinder

Slewing drive

  • Compact planetery reduction gear with hydraulic piston motor,
    integrated brake valves
  • Parking brake – Multi-disc broke, spring-loaded
  • Slew bearing – Strong ball bearing, sealed
  • Slewing speed – 0-2 rpm, stepless

Undercarriage

Crawler undercarriage T73/410 with hydraulic extendable track gauge, strong welded construction. Each track is independently driven by planetary final drive. Spring loaded hydraulically releasable multible disk brakes as safety parking brakes. Maintenance-free track-type B6 with 700 mm triple bar shoes
Travel speed: 0-2, 7km/h, 2·speed motors. High traction force and good ground clearance

Uppercarriage

Design – Torsion resistent box type design precision machined, steel bushes for the boom pivot. Clear, very service friendly design, longitudinal installation of the engine
