Use and Maintenance Manual - R13 R17 Series Page 8
All types of machine use other than those for which it was designed must be approved in writing by the machine manufacturer
following a specific request on the part of the user.
Do not use the machine for purposes other than those for which it was designed, except after making a
request and having obtained written permission in this sense from the manufacturer
1.3.1. Leaving at height
The work elevating platforms are not designed by taking into account the risks of the “leaving at height” because the only access
position considered is when the platform is completely lowered. For this reason this activity is formally forbidden.
However, there are exceptional conditions in which the operator needs to access or leave the work platform not in the access
position. This activity is normally defined as “leaving at height”.
The risks connected to the “leaving at height” do not depend exclusively on the PLE (work elevating platform) characteristics; a
specific risk analysis carried out by the employer can authorize this specific use by taking into account:

The working environment characteristics;

The absolute prohibition to consider the work platform as an anchoring point for people working outdoors;

The use of the machine at xx% of its performances to avoid that additional forces created by a specific operation or
bending of the structure move away the access zone from the unloading zone. Provide for some tests in order to define
these limitations;
 Provide for a specific evacuation procedure in case of emergency (for example: an operator always on the platform, one at
the ground control panel while a third operator leaves the lifted platform );
 Provide for a specific training of the staff both as operator and transported staff;
 Equip the unloading zone with all the devices that are necessary to avoid the risk of fall of the staff that accesses/leaves
the platform.
What said above is not a formal authorization of the manufacturer for the “leaving at height”, but it wants to supply information to
the employer - who is fully responsible for that - which can be useful for the planning of this exceptional activity.
1.4. Description of the machine
The machine described in this use and maintenance manual is a self-propelled aerial platform equipped with:
 motorized chassis equipped with rubber tracks and outriggers;
 hydraulically driven rotating turret;
 articulated boom operated by hydraulic cylinders (the number of articulations and cylinders varies according to machine
model).

operator platform (the max. capacity varies according to the model - see chapter "Technical features”).
The chassis consists of sheeting, box-type structures and electrically welded structural forms of different thickness. It is motorised
to allow the machine to move (see "General use instructions"). The 2 tracks are controlled by independent motors and equipped
with hydraulic parking brake, positive logic type (when drive controls are released brakes are automatically activated). On the
chassis there are four outriggers operated by hydraulic double acting cylinders that are controlled by solenoid valves directly
flanged on the same. The outriggers are held in position by non-return valves directly piloted and flanged on the same.
Upon request, the machine can be equipped with a system of tracks widening to widen the track width and increase stability in the
event of use on rough terrain.
The turret rests on a turntable fixed to the chassis and can be oriented (rotated) by 320° non-continuous around the central axle of
the machine by means of irreversible endless screw.
The lifting system , with articulated boom, can be divided into three main structures:
 The first one, consists of a "simple parallelogram" system (R13) or a "double parallelogram" (R17) and named
"pantograph".
 The second, consists of a lifting boom with telescopic extension.

The third, consists of the terminal boom named “Jib”.
Such lifting structures are driven by 4 double-acting hydraulic cylinders:
