3.1
General description of the machine
The frame of the
ZED 20.3 HV
elevating work platform is attached to the vehicle’s frame with bolts.
The upper part of the frame consists of a slip resistant aluminium platform.
There are 4 stabilisers fastened to the frame on mobile beams. They are positioned on the ground
hydraulically and are equipped with ground-contact and stabiliser-closed sensors.
The stabilisers are operated manually by means of a hydraulic valve with extending front beams,
through the relative extendible cylinders.
The rotating turret is ixed to a turntable that is mounted on the chassis. The turret rotation, ± 320°, is
limited by a mechanical blocking system that prevents the continuous rotation of the elevating work
platform by limiting it to ± 320°. It only it allows it to return to its starting point.
The boom unit, ixed to the turret, is composed of two articulated arms actuated by a hydraulic
cylinder that allows them to be moved simultaneously by means of connecting rods.
A telescopic boom, formed by 2 elements (one ixed and one extensible) is ixed to the articulated
boom. The telescopic boom is moved by a hydraulic cylinder. The lowering of the telescopic boom
is stopped when it is:
•
in the way of the vehicle cab, only allowing it to be moved away from the area.
•
in correspondence with the stabilisers, only allowing it to be moved away from the area.
The work platform, made of composite materials, with a guard rail made of aluminium, is anchored
to the telescopic boom. It is also equipped with a hydraulic cylinder operated rotation device 60° 60°.
The machine is moved by proportional electro-hydraulic controls.
The control station is located on the work platform.
The vehicle’s thermal engine powers the hydraulic devices by means of a hydraulic pump activated
by power take-off.
The electrical power for the controls is supplied by the vehicle’s battery.
The controls, the mode of operation and the devices installed on the machine are described in the
following pages.
