Hydraulic-system
All hydraulic pumps are variable displacement piston pumps with individual regulation for each pump. The pumps are equipped with an energysaving flow-on-demand control system and pressure cut-off for high efficiency and reduced loss of energy.
Max. flow rates:
- 310 l/min for travel and winch 1
- 310 l/min for travel and winch 2
- 230 l/min for boom hoist
- 210 l/min for swing 260 l/min for luffing jib winch
Working pressure up to 330 bar.
Hydraulic tank capacity: approx. 750/580 l
Hydraulic filters with long intervals be tween change.
Large dimensioned hydraulic cooling system.
Servo-assisted joy-stick controls according to ISO-System.
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.
Winches 120 kN max. Single line pull 1. Layer 160 kN Rope dia. mm 26 Line speed max. m/min 0-140
Optional: Additional crane winch
Swing drive 360° endless
The swing function is operated through hydraulic piston motor with oil bath planetary gear. Spring-loaded hydraulically releasable multiple-disc brakes selfclosing.
Large dimensioned triple roller type swing bearing.
Swing speed from 0 to 3 rpm, 0 to 1,0 rpm for crane operation.
Power transmission through 2 swing motors, thus less tooth pressure and moments. Precision swing operation with preselector switch.
Boom Hoist Operation
Hydraulically driven through a axial piston motor, spring-loaded hydraulically releasable multiple-disc brake, planetary gear and double winch drum with special scores. Max. line pull 110 kN, rope diameter 22 mm. 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 with low noise level.
Counterweight 38 t Hydraulic counterweight lowering system.
Undercarriage
Strong wide gauge crawler undercarriage. Each track is independently driven by an axial piston motor through planetary final drive. Spring loaded hydraulically releasable multiple-disc brake. Maintenance-free tractor type crawler with hydraulic track-tensioning device. Tractor type crawler B8b with 900 mm triple groucer shoes.
Optional: flat shoes Travel speed: 0 – 1.8 km/h.
Working equipment
Tubular boom 13.1-74.7 m, double sheave hammer head, luffing jib, fixed jib, auxiliary jib. Complete crane safety device with electronic SLI safe load indicator
Operators cab
Comfortable F 2000 operator’s cab, resiliently mounted, with exceptional sound suppression, large-capacity compartment with excellent allround visibility, all-weather design with tinted safety glass, front wind-screen with ventilation position stows under the roof, large-size skylight, window wiper/washer system for front windscreen and skylight, front guard panel, large-capacity stowage rack, ergonomically designed comfortable seat, resiliently mounted, adjustable in suspension and height, seat cushion adjustable in depth and angle, adjustable lumbar support, wide adjustable armrests, clearly laid out instrument panel with ergonomically shaped control levers, infinitely variable cab heating system, outside air and circulating air stages, with particle filter.
