  • Fuel tank capacity approx. 800 lCAT diesel engine C7 with direct injection


All hydraulic pumps are variable displacement piston pumps with individual regulation
for each pump. The pumps are equipped with an energy-saving flow-on demand control system and pressure cut-off for high efficiency and reduced loss of energy.
Max. flow rates:

  • 300 l/min for travel and winch 1
  • 300 l/min for travel and winch 2
  • 200 l/min for boom hoist
  • 200 l/min for swing

Working pressure up to 330 bar.
Hydraulic tank capacity approx. 900/710 l Hydraulic oil filters with long intervals between change. Large dimensioned hydraulic cooling system. Servo-assisted joy-stick controls according to ISOSystem. Central service tableau. Decomposable hydraulic oil (synthetic)
can be used. Hydro Clean hydraulic superfine filter with water absorption (optional).

Winch 1 - Winch 2

Each winch is driven independently by a directly flanged variable displacement hydraulic piston motor with high pressure regulation. Hydraulic brake valves for wear resistant braking of loads. Strong low maintenance oil bath planetary gears. The clutch and brake functions are effected through large dimensioned, maintenance-free, low-wearing, oil-lubricated multiple disc brakes. Grab closing automatics for 2 rope grab operation – dividing the load equally between both winches. Combilink – for dragline operation, allows

Winches 16 t
Single line pull kN 1.Layer 160
Rope dia. mm 26
Line speed m/min 110
Optional: Additional crane winch

Swing drive

The swing function is completely independent operated by a separate hydraulic circuit through 2 swing drives each with hydraulic piston motor and oil bath planetary gear. Spring-loaded hydraulically releasable multiple-disc brake, self-closing. Swing speed from 0 to 4,0 rpm, 0 to 2 rpm for crane operation. Precision swing operation with preselector switch.
Large dimensioned swing bearing, external gears thus less tooth pressure and moments.
Optional: Heavy duty triple roller bearing.

Boom Hoist Operation

Completely independent operation by a separate hydraulic circuit via axial piston motor, spring-loaded hydraulically releasable multiple-disc brake, planetary gear and winch drum with special scores. Max. line pull 45 kN (4.5 t). Drum pawl lock provides an integral drum lock.

Upper Structure

Torsion-free precision machined upper frame. All components are located clearly and service friendly. Engine installation very service-friendly in longitudinal direction with low noise level.
Counterweight 17.2 t


Undercarriage welded as rigid, torsion-free box-type design with integrated 4-point outriggers. The drive function is powered by 2 variable displacement piston motors with
directly flanged brake valves. 2-circuit servo brake system with additional safety brake as parking brake. Steering axle as hydraulically controllable oscillating axle. Oscillating axle cylinders with safety check valves.
Drive speed 0 – 10 km/h
70 t special wide gauge axles
8 tires, 14.00-24
8 tires, 16.00-25
