Use and Maintenance Manual - X_RT Series 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 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 Mobile Elevating Work Platform equipped with:
Motorised chassis equipped with wheels and, on request, with levelling outriggers (optional).
Vertical scissor lifting structure operated by one or more hydraulic cylinders (the number of cylinders varies according to
machine model)
Operator platform with manual slide-out extension deck (the max. capacity varies according to the model - see chapter "Technical
features
")
The chassis is motorised to allow the machine to move (see "General use instructions"). On 2 wheel drive models the chassis is
equipped with two rear driving wheels and two front idle steering wheels. On 4 wheel drive models the chassis is equipped with two
rear driving wheels and two front driving and steering wheels. All driving wheels are equipped with hydraulic parking brakes,
positive logic type (when drive controls are released brakes are automatically activated). On request the machine may be equipped
with levelling outriggers to operate on inclined grounds (but sufficiently firm). Even in this case the machine is enough steady to
operate on horizontal and sufficiently firm grounds and the platform can be lifted with the chassis resting on the four puncture-proof
tires without using the levelling outriggers. These must be used when operating on uneven but sufficiently firm grounds. The
levelling outriggers are controlled from the platform control panel, where machine levelling and operations in progress can be
checked by means of a spirit level. There is also a device (inclinometer) that disables the platform lifting and lowering in case of
imperfect levelling.
The hydraulic cylinders which move the articulated structure and the outriggers are provided with solenoid valves or safety valves
directly flanged on the same. This enables the machine to be held in position also in the event of an accidental breaking of the
supply pipe.
The platform, which can be manually extended from the front side, is equipped with rails and toe-boards of a prescribed height (the height of the
rails is ≥1100 mm; the height of the toe-boards is ≥150 mm, the entrance area has a toe-board of at least ≥100 mm).
When no motive power is available, the manual emergency lowering can be controlled manually by means of the knob indicated by
the instructions plates.
The capacity on the platform does not change depending on the position of the extension deck.
