2.5.5 ENABLING DEVICE OF THE STRUCTURE OVERHEAD PART
When all the stabilisers are properly placed on the ground, the stabiliser cylinder goes
towards the end of course releasing the micro‑switches situated at the end of the rods. The
micro‑switches send a signal to a solenoid valve that sends oil coming from the carry‑over
device to the controls for the movement of the overhead part of the structure. If for any rea‑
son a micro‑switch should reactivate during the movement of the basket (for example the
raising of a stabiliser or the sinking of the ground) all the movements of the overhead part of
the machine would be inhibited.
2.5.6 SENSOR OF CONTROL CAR LOAD
The load sensor present on the basket made up of a two‑shaft basket support that allows
exclusively vertical movement of the basket. Basket support is supplied by the load cell itself.
Two extensometers are positioned inside the sensor positioned under the basket, which swit‑
ch the relative weight inside the basket to an electric signal. The electric signal is sent to a
card (see photo) that elaborates it and identifies any dangerous conditions.
The maximum load depends on the work modality selected (par. 2.4.1.1 point 3). If the work
mode with jib has been selected, the load equals 120 kg. For the work mode with jib closed
jib the max. accepted load is 200 kg.
When the max. accepted load is reached, a flashing red light appears on the electric control
board as well as an acoustic signal and all platform movement is obstructed.
To restore platform functioning it is necessary to remove excess weight so as to fall within
the max. accepted weight.
