There is no kit available as a single item, however all components required
to lift a roof up to 1260mm, with a weight not exceeding 300kg are available.
Fixing screws and bolts to attach the roof must be purchased from a hardware
shop.
The length and width of your camper trailer can vary, within some constraints
and the bottom wall height will also effect the telescopic arms used.
Inside width should be at least 1.85m (if less it will directly effect height
of lift).
Length can be up to 3.6m. Any longer will require longer rear cables.
Using 4 stage telescopic lifting arms, the walls need to be at least 635mm high
and the roof will lift an additional 1260mm.
Using 3 stage telescopic lifting arms, the walls need to be at least 820mm high
and the roof will lift an additional 1120mm.
Starting with the winch you will need:
1 x ID-2219, Jayco Service and Repair manual
1 x ID-6178, Winch handle
1 x ID-6184, winch with brake, no handle, no main cable
1 x ID-5945, Main winch cable, with thrust race and harness plate
Next comes the four cables:
4 x ID-5948, Cable adjusting eye bolts
2 x ID-7004, Front corner cable, with cable clamp
2 x ID-7003, Rear corner cable, with cable clamp
4 x ID-5951, Slugs to suit push rod end of cable
The Floor tracks & Rollers
1 x ID-6446, Floor track, double roller
1 x ID-6447, Floor track, Left roller
1 x ID-6448, Floor track, Right roller
1 x ID-6449, Floor track, no roller
2 x ID-5941, Roller assembly, double for corners
Optional 2 x ID-5941, (additional to above) when a mudguard is present.
Corners and telescopic arms
4 x ID-5952, Push rods, 66 inches - may be trimmed
4 x ID-5954, Tubular push rod corner bend
4 x ID-465 or ID-465 Telescopic arms
How the system works
Above: The diagram shows a cut away view of the components
for raising one Lifting Arm.
Cable(l) is connected to a Slug(2) which
is inserted in a Floor Track(3).
This cable passes along the inside of the floor track, emerging
at the pulley end, where it passes around Pulley(4) and leads
away to the Eye bolt(5).
Also inserted in the floor track is a Push Rod(6) (a flexible
compressed spring) which rests against the slug and protrudes past the pulley.
Mounted a short distance from the pulley end of the floor track, and
in line with it, is a Corner Bend(7). The vertical end of the
corner bend is inserted into the lower end of the Telescopic
Lifting Arm(8), which is mounted in the wall of the Camper trailer.
The protruding length of the push rod goes inside the corner
bend and enters the lifting arm. It passes through the larger
outer sections and rests against the blanked lower end of the inner (top) section
of the lifting arm. There is an end plug in the top end of the push rod. It’s purpose is to avoid the possibility
of the push rod accidently catching under the lower end of the larger
sections of the lifting arm, by guiding it past the entry of each section.
Operation
As cable(a) is pulled by the winch,
the slug forces the push rod(b)
through the floor track.
As the push rod curves around the corner bend and moves further
into the lifting arm assembly, it passes through the lower sections and
forces the top section (c) upwards.
When the top section is fully extended a 'Stop' at it’s lower end engages
the second section and takes it upwards. This continues until the required height
is attained.
This assembly and operation is replicated in all four corners of the Camper Trailer.
The four cables (one from each floor track ) are brought via
the pulleys to a common direction where they are grouped up and coupled
to a winch for joint operation.
