Boom
Formed by three segments: one is fixed, two are hydraulically extensible by means of a hydraulic double-action and return cylinder.
The system allows to extend the boom in a synchronous way. Boom lifting operations are managed by a double-action cylinder which allows a -5° to 70° swing angle.
Lifting capacity 12 ton
Frame made of steel sheets highly resistant to yielding, duly folded and welded.
WINCH
Grooved drum (lebus threaded) with non-rotation steel rope, variable displacement hydraulic motor, planetary gearmotor with disc brake and safety/functioning valve, automatically activated.

Hydraulic System
Composed of a “load-sensing” variable displacement pump with torque control, connected to a 35 kW, 96 V AC electric motor to power extension movements, boom lifting, winch, steering, front outriggers and auxiliary equipment operations.
Distributor with differentiated spools, managed by an electric proportional control. Multi-function electronic joystick. “Over centre” valves for the cylinder actioning lifting, boom extension and winch movements. Pilot shut-off valves for stabilizers cylinders. Pump oil filter with electric clogging alert. Hydraulic oil tank capacity: 380 l. Max working pressure: 280 bar
