1.8 Description of the MAXON liftgate components
Electrical system/operating unit
The individual functions are controlled via a very flat control panel with four membrane
switches (see page 22). Optionally for some models, the functions are initiated via the
2-button control panel (see page 23) or the version with two lateral toggle switches (see
page 24) or via a handheld control (see page 26). The interface between the liftgate and
the vehicle complies with ETMA guidelines.
Foot controls (option)
The foot controls (option) on the platform (see page 25) are mounted inside a protective,
die-cast aluminum housing. They can be used to lower the liftgate to the ground and lift it
to the height of the vehicle floor. The platform automatically tilts up and down to a
position horizontal with the ground.
Priority control
The foot controls are a priority control. When the liftgate is operated via the foot controls,
other control options (control panel, handheld control) are automatically locked out
electrically.
Hydraulics
The liftgate is driven by a compact power pack mounted on the supporting structure or
directly on the closing cylinder or integrated in the axle assembly. This power pack serves to
move the lifting or closing cylinder(s) to the desired position as well as the two cylinders of
the optional hydraulic supports. The hydraulic cylinder’s connecting rods are nitrided.
Lifting gear
The lifting gear (flange brackets as well as lifting and closing arms) comes with its final
surface ex works and is painted black (RAL 9005). All bearing points are maintenance-free
and require no lubrication. The flange brackets and installation adapters are adapted to the
frame of the vehicle type ex works. The interface complies with the ETMA standard. Each
liftgate type is tested with 80,000 load changes before being approved for production.
The lifting gear (flange brackets, lifting and closing arms, and underbody impact guard)
comes with its final surface ex works and is painted black (RAL 9005). All bearing points
are maintenance-free and require no lubrication. The flange brackets are adapted to the
vehicle’s frame width. The underbody impact guard is a single part. Each liftgate type is
tested with 80,000 load changes before being approved for production.
Platform
The platform comprises clipped-together aluminum hollow sections that are stabilized by
means of welded tip and end sections. The platform has a smooth back for optimally
accommodating advertising labels.
