Main Diesel tank capacity
Secondary Diesel tank capacity
The excavator is equipped with a pump that can be used to transfer the Diesel from the
secondary tank to the main tank or to pump the Diesel out from a canister.
Penetration force (ISO 6015)
Brake off force (ISO 6015)
It must be clear that the excavator is not a lifting equipment, if an excavator is going to be
used, also for a few times, as a lifting equipment, the main boom as well as the secondary
boom cylinders must be equipped with locking valves. The transformation can be requested at
the moment the machine is ordered.
Dimensions of the under carriage:
Minimum spread of the rear legs
Maximum spread of the rear legs
Minimum spread of the front legs
Maximum spread of the front legs
Extension of the front legs
Dimensions of the upper section (version C):
Maximum excavation depth
Maximum unloading height
Maximum boom length
Minimum rotation radius of the turret
Minimum rotation radius of the boom
Length of boom extensible section
Motion
The excavator moves with two groups made out of a hydraulic motor, brake and gearbox. 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. The machine has two speeds that can be selected with a switch. The
change of the speed is effectuated changing the displacement of the hydraulic engine.
Speeds
Maximum speed in 2nd gear
The two groups can be set in neutral condition when the excavator must be pulled.
The differential locking device is standard and it can be unlocked from the cabin.
The two front wheels can be taken off by removing the locking pin.
Rear tyres
On request it is possible to have other tire dimensions.
Front tyres (diameter 890 mm)
A dedicated piston pump is installed for the closed circuit traction only on the "H" version.
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 limitate the shocks to the structure.
