4. FEATURES OF THE MEWP
4.1 DESCRIPTION OF MEWP
DESCRIPTION:
This aerial platform has been designed to be mounted on a road motor vehicle. It is made up of:
-
a
structure (platform)
made up of a rotating turret; its rotation is possible by means of a ball bearing
fifth wheel. On the turret peak, an articulated boom is hinged, which is , which is connected to a
telescope boom (with a 3 extensible elements), jib boom and basket support. On this latest element, the
basket is hinged.
-
a base support structure (basic-counterframe)
made up of longitudinal frame members and cross
members on which the fifth wheel of the turret is fixed; also 4 stabilizers and the oil tank are part of the
basic counterframe.
-
a hydraulic equipment
which controls the movement of the machine.
-
an electric equipment
which feeds the electric system of the vehicle.
All the machine’s movements are hydraulic and there is always a corresponding safety valve.
The platform has an emergency manual lowering system which must only be used in the event of a
breakdown and/or if there is a fault in the main power supply circuit.
If the machine is not stabilized properly or loses stability, the buzzer will sound with the corresponding
signal indicating that a stabilizer is not in contact with the ground. The machines allows for retraction
operations at a reduced speed.
The cage is made of electrically welded aluminium tubes and the basket support is fitted with attachments
for the safety belts. The entry is in the front lifting the bar with automatic closing and it is accessed directly
from the ground by a small ladder.

1. Controls in vehicle cab
: used to activate the hydraulic system
2. Rotating beacon over the cab
:
signalling device. It is activated from the controls in vehicle cab.
3. Articulation for main boom
: it is made up of a fixed fulcrum element fixed at section of lower
boom and at main boom.
4. Main boom
:
it is made up of a fixed fulcrum element (fixed at its articulation) and
by extractable elements which are activated by a hydraulic cylinder.
5. Cylinder for telescoping boom
:
actives the extraction of the telescoping elements of the main boom.
6. Jib
:
it is made up of 2 elements.
7. Basket controls
: they are used by the operator in the basket to do all manoeuvres.
8. Basket
:
it is the structure where 1 or 2 operators stay. It can also contain
some tools (if allowed). A hydraulic device guarantees the basket
verticality at each working angle of the boom. It can be made of
