2.1 Description
The work platform consists of a self-propelled all
welded steel frame, a telescopic mast mounted on a
turntable and a pendular jib. The platform is mounted
at the end of the jib.
The drive function is accomplished by two hydraulic
motors which propel the rear axle.
The steering function (front axle) is accomplished by
a hydraulic cylinder supplied with a hydraulic pump
unit located on the chassis between the steering
wheels.
The parking brakes integrated to the hydraulic motors
work through lack of pressure.
The main hydraulic power unit supplying the functions
of the work platform (except steering) is located at
the top of the main hydraulic tank, at the rear of the
chassis.
The turntable rotation movement is accomplished
through a moto-reducer group located at the base of
the turntable.
The movement of the pendular jib is accomplished by
means of hydraulic cylinder.
The work platform movements are controlled from the
control boxes through hydraulic control valves
controlled electrically located at the front of the
chassis.
The progressivity of movements is obtained by an
electronic controller which controls the rotation speed
of the main hydraulic group motor. The electronic
controller is located near the emergency control box
(ground controls), on the left hand side of the
telescopic mast.
The energy for the control and power circuits of the
work platform is supplied by a 24 VDC battery.
