Use and Maintenance Manual - Series V8 E V10 E Page 8
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 mobile elevating work 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 th e
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 elevating work platform equipped with:
▪
motorized chassis equipped with wheels;
▪
hydraulically driven rotating turret;
▪
lifting system (extensible struct ure) composed of telescopic column with vertical extension and the “jib”;
▪
operator platform (the max. capacity varies according to the model - see chapter "Technical features”).
The chassis is motorised to allow the machine to move even with lifted platfor m (see "Use instructions”) and has two rear driving
wheels and two front idle steering wheels. The rear wheels are equipped with parking brakes, positive logic type (when drive controls
are released brakes are automatically activated). On the chassis there are two fixed pot-hole guards which reduce the ground
clearance close to the wheels and they guarantee the stability of the machine with a wheel in a hole.
The turret rests on a turntable fixed to the chassis and can be oriented (rotated) by 360° non-continuous around the central axle of
the machine by means of irreversible endless screw.
The lifting system can be divided into two main structures:
▪ the first, with vertical extension, consists of a telescopic column;
▪ the second, consists of the terminal boom named “Jib”.
The hydraulic cylinders which move the extensible structure are single-acting and they are provided with normally sealed closed
valves directly flanged on the same. These devices allow the booms to remain in position even if one of the supply tubes accidentally
breaks.
The platform , hinged to the end of the “jib”, is equipped with guard -rails and toe-boards of a prescribed height (the height of the
guard-rails is

1100 mm; the height of the toe-boards is

150 mm; in the access area the toe board height is

100 mm). The
platform levelling is automatic and it is ensured by the jib tie rods.
