Important Notes
This PALFINGER Liftgate is an electro-hydraulically driven lift gate, designed to be stored underneath the
truck or trailer for ultimate dock loading as well as offering up to seven foot platform.
The Hydraulic Power Unit (HPU) is easily accessible for service and exchange. The whole assembly slides out
and can be serviced at that point. To exchange the Hydraulic Power Unit (HPU), two hoses and the battery
cables need to be disconnected.
The platform folded in half is supported by two arms, linked with a torsion tube. The platform in a stored
position acts as the under ride guard. Lifting actions are carried out by hydraulic cylinders mounted on the lift
arms.
Two hydraulic tilt cylinders, one on each side of the lift arms are controlling the platform’s tilting action. This
enables the platform to maintain its position throughout the lift mode, regardless of the terrain.
The hydraulic cylinders are equipped with solenoid operated valves located at the port of each cylinder which
prevents the platform from lowering accidently unless the operator is activating the controls. This system also
enables you to store the lift gate without a separate platform latch.
The piston rods are treated against corrosion and also protected with plastic or rubber boots to protect from
road gravel and dirt. The HPU is equipped with a built-in pressure relief valve, which prevents overloading
when lifting or tilting up.
The valves do not prevent overloading of the platform when lowering or tilting down.
