The PEP 8400 is made by a basement, a lifting device and working platform .

Lifting platform

The lifting device consists of two rear and two side pantographers.

All pantographs are composed of six pairs of arms; the side pantographs are guided by two cylinders each, while each rear pantograph is activated by one single cylinder.

The working platform, thanks to the action of a double acting oleo dynamic cylinder, can move horizontally in order to allow a closer approach to the aircraft.

Basement

The basement is composed of a fixed part linked to the frame of the truck and a moving part connected to it by a thrust-bearing block in order to allow a rotation of 180° of the lifting device.

Stabilizers

The fixed part of the basement has four stabilizers, each of them are activated by an double acting oleo dynamic cylinder, which allows a higher stability to the truck when platform is lifted.

Safety lights fitted on upper part of cabin

The lifting platform is composed of:

- stabilizers control panel;
- Control panel on the working platform.

The stabilizers' command panel is on the left side of the truck, behind the driving seat with the following functions:

- Rear right stabilizer;
- Rear left stabilizer;
- Front right stabilizer;
- Front left stabilizer;

Oleo Dynamic system

The oleo dynamic system comprises of an oleodynamic pump calibrated for a max press of 130 bars, driven by the engine of the vehicle.

Linking engine-pump is obtained by an electromagnetic switch commanded by dedicated switches incorporated in the oleo dynamic distributors.

Max regulating press valve: set the pressure for the operation of the hydraulic system.

Commands Features:

When platform is extended start and shut off engine commands are available.

Emergency hand pump available on ground for emergency operations.

Stabilizers command lever.
