Aerial manoeuvres enabling
Its function is to allow the aerial platform to be moved only when the machine has been stabilised.
There is a micro switch on the foot of each stabiliser, located below the stabiliser carter, that detects
if the stabiliser is resting on the ground. There are another two micro-switches on the vehicle’s rear
springs which detect minimum stabilisation. When the machine is being stabilised, indicator lights
1, 2, 3 and 4 next to the stabilisation controls will light up only when all the feet are resting on the
ground and the minimum stabilisation has been reached (see Fig. 4.3), and it will then be possible
to raise the boom.
SAFETY DEVICE FUNCTIONALITY CHECK
•
stabilise the machine so that indicator lights 1, 2, 3 and 4 come on (see Fig. 4.3).
•
retract one stabiliser until the corresponding light turns off.
•
try to move the aerial platform. It should not be possible to do so.
5.7
Chain tension monitoring system
The booms are extended and retracted by a hydraulic cylinder integrated with drive chains.
There is a series of micro switches that detect the breakage or elongation of the chains. (see Fig.
5.4, 1).

SAFETY DEVICE FUNCTIONALITY CHECK
•
The condition of the chains that extend the telescopic elements of boom can be inspected
visually by examining the chains located under the booms.
•
Micro switches are installed on this machine that detect the breakage or elongation of the
chains. In this case and in general, if abnormal chain wear is detected you must contact
an authorized CTE service centre. The platform requires extraordinary maintenance to be
carried out on the chains (replacing or removing links).
