Hydraulic-system

4 circuit hydraulic system for best funktion 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 flow-on-demand control and preasure cut-off for high- efficency and reduced loss of energy.
Oil flow max. 3 x 420 l/min 1 x 270 l/min
Pressure max. 340 bar

Swing drive in closed loop circuit. Axial piston pump in closed loop ciruit, torque control energy recovery during decelleration.

Filtration High-efficiency filtration with long-time change interval, pollution indicator

SENNEBOGEN HydroClean micro filtration with water separation,
Hydraulic tank 1020 l / 880 l

Steering Proportional, servo hydraulics, precise control of the working functions, 2 servo joysticks for ope- rating movements, additional functions through switches and foot pedals – in a clear and ergono- mical layout
High efficiency through well sized hydraulic valves and lines
Central test ports for hydraulic circuits
Safety valves for all hydraulic circuits

Swing Drive

2 Compact planetary reduction gears with hydraulic piston motor, integrated brake valves

Parking brake Multi-disc brake, spring-loaded

Swing bearing Strong bearing, sealed
Swing speed 0-4,0 rpm, stepless

 

Upper Carriage

Torsion resistant box type design, precision machined, brass bushes for the boom pivot
Clear, very servicefriendly design longitudinal installation of the engine

Boom Hoist Operation

Completely independent operation by a separate hydraulic circuit over axial piston motor, spring-loaded hydraulically releasable multiple-disc brake, planetary gear and double winch drum with special scores. Max. line pull 2 x 80 kN. Drum pawl lock provides an integral drum lock.

Cooling System

Large sized cooling system for the engine and hydraulics. Very energy efficient and noise emission reduced through thermically controlled drives

Winch 1 - Winch 2

Each winch is driven independently by a directly flanged preassure 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-main- tenance oil bath planetary gears. The clutch and brake functions are affected by large-dimensioned, maintenance-free, low-wearing, oil- lubricated multiple disc brakes, oil cooled.
The individually, variable adjustable winch brake supports activly the driver, prevents loose ropes and takes care of the machine.
