Hydraulic-system
Multi-circuit hydraulic system far best function and performance for the duty cycle crawler crane, all functions can be driven simultaneously. The hydraulic pumps are variable displacement piston pumps with individual regulation for each pump. The pumps are equipped with an energy-saving flaw-on-demand control and preasure cut-off for high efficiency and reduced lass of energy.

Pressure max. – 340 bar
Filtration – High-efficiency filtration with long-time change interval, pollution indicator
SENNEBOGEN HydroClean micra filtration with water separation, optional
Hydraulic tank – 700L/550L
Control – Proportional, servo hydroulics, precise control of the working functions, 2 servo joysticks far operating movements, additional functions through switches and fast pedals – in a clear and ergonomical layout
High effrciency through well sized hydraulic valves and lines
Centraltest ports far hydraulic circuits
Safety valves for all hydraulic circuits
Slewing Drive
Compact planetary reduction gears with hydraulic piston motor, integrated brake valves – Positioner slew brake
Parking brake – Multi-disc brake, spring-loaded
Slew bearing – Strong bearing, sealed
Slewing speed – 0-4.5 rpm
3 adjustable slewing speeds
Upper Carriage
Torsion resistant box type design, precision machined, brass bushes for the boom pivot
Clear, very service friendly design longitudinal installation of the engine
Cooling System
Large sized cooling system for the engine and hydraulics, very energy efficient and noise emission reduced through thermostatically controlled fan drives
Winch 1 - Winch 2
Each winch is driven independently by a directly flanged pressure regulated variable displacement hydraulic piston motor, this ensures at any time the best regulation of line speed and line pull. Hydraulic brake valves for wear resistant braking of loads. Strong low-maintenance oil bath planetary gears. The clutch and brake functions are effected by large-dimensioned, maintenance-free, low-wearing, oil-lubricated multiple disc brakes, oil cooled.
The individually, variable adjustable winch brake supports actively the driver, prevents loose ropes and takes care of the machine.
