Attachment
Geometry ___________________________ Powerful and stable “LogHandler” lifting equipment
for optimum lifting heights. 360° rotating grapple tool
Bearings ____________________________ Sealed
Brakes
Wear-free service brake ___________ Self-locking of the hydrostatic travel drive (acting on
all four wheels) and additional pump-accumulator
brake system with wet multi-disc brakes (two
sepa rate brake circuits)
Parking brake ______________________ Electro-hydraulically actuated spring-loaded brake
system on the transmission
The braking system meets the requirements of the EC guidelines 71/320.
Travel Drive
Stepless hydrostatic travel drive
Design
________________________ Swash plate type variable flow pump and two
variable axial piston motors in closed loop circuit with
one axle transfer case. Direction of travel in reversed
by changing the flow-direction of the variable-
displacement pump
Filtering system _______________ Suction return line filter for closed circuit
Control ________________________ By travel and inching pedal. The inching pedal makes
it possible to control the tractive and thrust forces
steplessly at full engine speed. The Liebherr joystick
is used to control forward and reverse travel
