Hydraulic-system

Multi-circuit haydraulic system for optimal function and capacity, running all movements simultaneously is possible. The hydraulic pumps are variable displacement piston pumps with individual control and energy-saving flow-on-demand control. The pumps only request as much oil as is actually consumed. Pressure cut-off, load limit sensing control.
Delivery rate: maximum 3 x 220 l/min
Operating pressure: to 330 bar
Filtration: High performance filtration with long-term change interval, contamination level indicator
Hydraulic Tank: 550L
Control system:Proportional, precision hydraulic servo controllers of work environments, 2 hydraulic servo joysticks for work functions.

Slewing Drive

Gearbox: Compact planetary gear with slant axis haydraulic motor, integrated brake valves – positioner slewing gear brake
Parking Brake: Spring loaded disk brake
Slewing Ring: Ball bearing rotary connection with exterior gearing
Slewing Speed: 0-4 rpm, 3 adjustable slewing speeds.

Upper Structure

Design: Torsion-resistant box design, precision crafted, bronze bushings for boom bearing arrangement.
Lighting: LED spotlights for optimal illumination of the work area
Safety: Camera monitoring of the rear area and right side.

Winch

The winches are driven via the high-pressure regulated adjustable hydraulic motors, thus there is always optimal pulling force speed control. Hydraulic lowering brake valves for sensitive wear-free braking. Strong oil bath, planetary gear, low maintenance.
Crane brake and free-fall brake are sping loaded, maintenance-free, low-wear disc brakes running in the oil bath, oil-cooled. The individual, variablky adjustable free-fallbrake actively support the operator, prevents slack cable and protects the machine.
Winches 12 t 16 t
Single line pull kN 1.Layer 120 160
Rope dia. mm 22 26
Rope speed m/min 0-125 0-120

Undercarriage
