HYDRAULIC TRAILER MOUNTED BOOM LIFT
Hydraulic Trailer Mounted Boom Lift
is originally imported by German haw electro- magnetic valve, proportional
control valve and proportional amplifier. British proportional handles Italian
bi-directional balance valves and French proximity sensors and relays.
Electro-hydraulic proportional
control, step less speed regulation and superior operational performance. There
are two control boards, one is on the work platform and the other one is
chassis. Both of them achieve remote control of engine. The four outriggers can be independently controlled; featuring good adaptability.There is elevation angle limit device for the upper arm, which can avoid danger.
The interlock between the superstructure and undercarriage and the soft outrigger protection function ensure safe operation.When the horizontal outriggers are not extended, the slewing of the work arm is limited, while it can still be lifted or lowered, which ensures safety and improves efficiency.
