The BGVL ALU booms are structured with a central body mounted on a pendulum system and 4 arms (2 on each side). They have 9 hydraulic functions that are controlled from the tractor (cab control, electro-valve body): independent arm opening/closing (4), parallelogram lifting (1), central body locking (1), slope corrector (1) and variable geometry left +/- and
As always, we have taken care and optimized the damping of the movements that have an impact on the structure of the bar, combining 2 systems:
- a.- Pneumatic suspension (air + gas shock absorber) in parallelogram lifting.
- b.- Hydro-pneumatic suspension by nitrogen balls to dampen the movements with whiplash effect and to smooth the work of the variable geometry.
