Important Notes
The PALFINGER Liftgates ILSL model 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 6-1/2 feet 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 torsion springs, each on one side, one support folding the other
unfolding operation. 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.
The gate is equipped with swing fixtures mounted to the bottom on each lift cylinder. This enables the platform
to lower down the tip towards the ground.
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. The HPU is equipped with a built-in pressure relief valve, which
prevents overloading when lifting.
The valves do not prevent overloading of the platform when lowering or tilting down.
