Important Notes
The PALFINGER Liftgates ILSL model is an electro-hydraulically driven lift gate, designed to be stored
underneath the 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 platform folded in half is supported by two torsion springs, each on one side, one support folding the
other unfolding operation. 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.
The electric supply is taken from the auxiliary batteries. The electric control power is protected via a 20 Amp
fuse and an on-off switch. Trailer application has an on-off switch located in the lockable control box. The
liftgate is operated from an outside control box which is located on the curbside of body. Foot controls are
optional, which enables the operator to handle the cargo and operate the liftgate by foot. A variety of
different product options can be purchased with the liftgate as well.
