wheels and the handbrake released. The
hitch head should be checked to see that
it is fully extended and that there is no load
on the braking system.
Maintenance –
AL-KO Lightweight Chassis
AL-KO Galvanised Chassis
Hot dip galvanising offers high corrosion
protection by forming a barrier layer
through reaction with the atmosphere.
This will be apparent by the chassis
members changing to a light grey
colour. During winter periods or storage
where there is insufficient air circulation
or heavy moisture, a soft porous, light
grey oxidisation layer may form. This is
known as ‘White Rust’ and should NOT be
confused with rust.
The Axle
The AL-KO rubber suspension axle has
been designed for new standards of spring
comfort and is maintenance free.
Three rubber elements are contained
within a hexagonal axle tube. These
provide suspension and have inherent
damping characteristics.
Figures 1(A), (B) and (C) show the
deformation of the rubber elements at the
extremes of suspension movement.
The axle is designed to ride with the
suspension drop arm at, or slightly below,
the horizontal position.
Suspension shock absorbers
All Coachman caravans are fitted with
AL-KO Octagon Shock Absorbers to
provide increased damping characteristics
and to improve road holding.
