AL-KO CHASSIS & TYRES
100
ALKO RUNNING GEAR
Coupling Head
The ball couplings are entirely automatic in
operation and designed for one hand
operation to suit the 50mm international ball
recommended by the British Standards
Institution, National Caravan Council and the
Society of Motor Manufacturers and Traders.
It is expressly forbidden by the chassis
manufacturer for holes to be drilled into
the 'A' frame to accommodate a stabiliser
bracket. A clamp must be used. Similarly,
holes should not be drilled into the
coupling head.
Operation of hitch head
Lift handle upward and forward. Place the
unlocked coupling onto the towing ball and
with the slightest downward pressure it will
lock onto the ball automatically. Ensure
locking trigger returns to its free position and
indicator button shows green before
commencing to tow.
CHASSIS & UNDERGEAR
The Chassis
The design of the chassis undergear is
suitable for the sustained high speeds
permissible on mainland Europe
(130 k.p.h.).
The maximum static load at the coupling
head is 100kg.
The chassis is capable of carrying your
caravan to the Maximum Technical
Permissible Laden Weight as shown at the
back of the service handbook.
The towing hitch (50mm dia. ball)
operates on the over run principle; the
application of the towing vehicle brakes
automatically, mechanically operating
the brakes of the caravan.
No manual assistance is needed to
activate the auto reversing mechanism
which automatically comes into operation
when the towing vehicle starts to travel in a
reverse direction. No lock off device needs to
be used.
As the name implies, the corner steadies are
designed to steady and stabilise the caravan
when parked. They are not designed as
jacks.
The AL-KO chassis is galvanised steel. To
maintain protection to the steel, any rusting
areas should be recoated using galvanising
paint.
Uncoupling
Having lowered the jockey wheel to the
ground, operate the handle as previously
described. Lift the coupling clear of the
towing ball either manually or by operating
the telescopic jockey wheel.
BRAKING SYSTEM
(AL-KO Automatic Reversing Brakes)
Forward Braking
In the free position, with the drawshaft fully
extended and the handbrake lever fully
forward “off position” the wheel brake shoes
are clear of the drum and there is no friction.
During braking travel on the main shaft of the
overrunning device is transmitted via the
overrun lever, brake rod and bowden cables
to the expander mechanism inside the wheel
brake. The fully floating expander
mechanism (2) forces the leading brake shoe
(1) and by reaction the trailing brake shoe (3)
into contact with the brake drum.
The friction between brake shoes and drum
creates a tendency for both shoes and
expander to move with the forward rotation
(4) against the solid abutment of the adjuster
box (5) which ensures both shoes remain in
the braking position.
