TRITURADORA DE BRAZO HIDRÁULICO PROFESIONAL
MARTINA è adatta a trattori di media potenza e con massa fino a 2800 kg, per un uso continuativo dello sfalcio di fossati e argini. MARTINA 600T ha il braccio telescopico con uno sfilo di 800mm che permette un'apertura fino ai 6,4 m, ideale per lavori di manutenzione stradale in spazi non molto ampi.

Head of hedge cutters permits maximum working flexibility, thanks to its rotation angle of 246°; balanced rotor warrants absence of vibrations.
Floating head allows user to follow uneven ground contours without acting on motion control. A safety system limits maximum head oscillation so, in case of sudden level drop, risk of head falling or tractor overturning are prevented.
All hinges have pins made of hardened, heat-treated steel; bushings are wear resistant and provided of lubricating nipples.
It’s possible to invert spin direction of rotor: this makes the machinery suitable both to cut grass, shrubs (clockwise spin) and operate close to water along rivers (anticlockwise spin). To prevent any accidental inversion, the lever for this function has a safety block.
Hydraulic circuit can be blocked by shut-off valves: this allows user to perform safely maintenance operations, without any dangerous accidental movement of the arm.
Cast iron made gear pump is more resistant to high temperatures comparing to aluminum: this technical choice is suited to professional use under intense and stressing work conditions.
In case of sudden rotor arrest, a safety valve drops pressure from hydraulic engine to prevent any damage.
A double safety system is active when the arm encounters any obstacle. First protection is a nitrogen dampener working with a hydro-pneumatic circuit. If first system is not sufficient a max safety valve, acting on a cylinder, turns back 90° the arm.
