2.2 General description of the machine
The Zed 23.2JH elevated work platform is composed of a frame fixed using bolts to
the chassis. The upper part of the frame is covered with a slip-proof aluminium deck.
Four hydraulic-operated outrigger feet are fastened to the chassis to stabilise the
machine. The outriggers are moved by a manually-activated hydraulic distributor. The
rotating turret is fixed onto the chassis, mounted on a bearing turntable and activated
by a hydraulic motor. The turret turns by 360°. The boom unit is fixed to the turret. This
is composed of two articulated booms activated by a hydraulic cylinder that allows
simultaneous movement by means of connecting rods. A telescopic boom with two
elements (one fixed and one extendible) is fixed to the articulated boom. The
telescopic boom is moved by a hydraulic cylinder. An articulated boom (jib) is
anchored to the telescopic boom. This is activated by a hydraulic cylinder. The work
platform is anchored to the articulated boom (jib). This has a hydraulic jack rotation
device. The work platform is kept horizontal by a hydraulic parallelogram levelling
device. The machine is moved by proportional hydraulic controls. The control position
is in the work platform. The source of energy for moving the hydraulic device is
supplied by the endothermic engine of the vehicle via hydraulic pump activated by
power take-off. The electric power supply to the controls is supplied by the vehicle's
battery. The following pages describe the controls, functioning modes and the devices
present on the machine.
