Installation - Mechanical Components
To begin mechanical installation, ensure that your caravan is placed on a hard, level surface. Where
possible the use of a lifting ramp or an assembly pit is ideal for access and personal safety.
Make sure your caravan is prepared for installation. Clean the relevant mounting areas of your chassis
to ensure a secure fitting of the mover system. Check before installation that important areas, such as
drains, spare tyres etc. do not cause any obstruction to the installation of the mover system and its
intended functionality.
Unpack all of the components and check that all parts are present (see Package Contents Fig.A). The
installation instructions will continue to reference the part numbers displayed in Fig.A. Prior to and
throughout the installation, ensure that the movers remain in the DISENGAGED position (see Fig.4),
as the unit will not fit correctly otherwise.
Loosely assemble motor framework side (1), motor framework side (2) and main cross bar (3) (see
Fig.1). The nuts (Fig.1.A) for cross bar fixing must be no more than finger-tight at this stage.
Place the assembly (Fig.1) loosely under the caravan. In principle, the unit should be fitted in front of
the caravan road wheels, but if fitting in this position is not possible, it is permissible to fit it to the rear
of the wheels by rotating the whole assembly by 180° degrees (note: in this scenario, later refer to Fig.
15 for rear axle wiring schematic). Ensure that the Main Cross Bar (3) is positioned in the centre of the
caravan/mover assembly (the centre is marked). Adjust the assembly so that the mover rollers are in
line with the tyres, this can be adjusted slightly again later.
Study Fig.9. On one side of the vehicle, elevate the framework assembly and loosely fit the clamping
assembly to the framework and chassis as per Fig.10. Provided clamp fixings (7,16,17,18) must be no
more than finger-tight at this stage. Once self supported via the loose fixings, proceed to repeat the
process on the other side of the vehicle.
Take due care when elevating and fixing the framework and clamps. Use lifting aids and/or a
second persons when lifting/fitting.
With the main assembly loosely fitted onto the chassis, slide the whole assembly along the chassis
until the rollers (Fig.2.A) are 20mm away from the surface of the each tyre (see Fig.4). Two 20mm
spacers (30) are provided to set this distance. Note that the movers should be in the disengaged
position when the 20mm spacing is set. When setting the spacing, ensure that the rollers on both
movers are centrally in line with the vehicle tyres both horizontally and vertically, to allow for the best
possible wheel contact (see Fig.6 for reference). If the roller widths exceed that of the tyre, ensure that
the end of the roller is aligned with the outer wall of the tyre. Overhang on the inside wall of the tyre is
acceptable on thinner tyres, and should not drastically affect function or grip.
It is vitally important that each roller is at exactly the same distance away from the tyre. The
whole assembly must be parallel to the caravan/trailer axle for the system to operate as
intended.
