Motion
The excavator moves with two groups made out of a hydraulic motor, brake and gearbox. A
specifically set compensated flow divider controls the function. The braking function is
controlled through the two negative brakes. The movement function is controlled with a foot
pedal, which controls both the forward and the reverse motion, this function can be feathered.
In option the machine can have two speeds that can be selected with a switch.
Speeds
Maximum speed in
Maximum slope that can be negotiated
The two groups can be set in neutral condition when the excavator must be pulled.
The two front wheels can be taken off by removing the locking pin.
Rear tyres
Front tyres
It's possible to install different wheels, in this case the values of speed and slope can change.
In option the excavator can be equipped with a second speed.
Rotation
The rotation is achieved through a slew bearing moved by a hydraulic motor coupled with a
planetary gearbox and a negative stationary brake. The rotation speed can be feathered. The
dynamic braking is controlled by damp valves that reduce the shocks to the structure.

Hydraulic system

Main pump
55 cm3 + 55 cm3 double variable displacement axial piston pump with constant power
governor:
Maximum capacity
Maximum absorbed power
Secondary pump
The secondary pump feeds the under carriage section. In the case that the legs are not used,
this pump feeds the boom.
This pump is a gear pump with fix displacement.
Maximum capacity
Maximum absorbed power
