The steel components are electro galvanised (with a trivalent coating) or where possible hot-dip galvanised. This is the process used for most automotive and earth-moving equipment underbody parts. Periodic washing will help to remove salt deposits. Occasional DWF ( Castrol ) spraying will help in high corrosive environments. All components are +3mm steel, With the exception of the steel drum which is 2mm. Any corrosion might look unsightly but very unlikely to prevent proper functioning.
The response is instant. Giving instant feedback, to the operator so errors can be corrected quickly. Very accurate positioning is easily achieved. There are only two switches to operate.
It is perfectly ok to leave motors engaged with the tires for short periods of time ie a week or two. The motors apply only about 130kg force. This is minimal when considering the bottom of the tire is supporting ½ the weight of the caravan 500-750kg.
For record purpose guarantee at least a year, whether DIY or otherwise any part that fails will be repaired or replaced. This excludes damage through circumstances such as bolder hopping and potholes etc. The most expensive single component is the motor gearbox. If a replacement is required we will charge a handling fee and can be couriered to most parts of SA within 24 hours, 48 hours to remote parts.
The maximum speed is 5 meters per minute which is not very fast so the Soft start only creates a delayed response, as does the soft stop (overshoot). These delays create a degree of positional problems and skilled operation is needed. The drive is via the outer surface of the rubber tires and as such is relatively ”soft”, so the shock is minimal. The upside is the control is extremely positive, with an immediate response which allows for very accurate positioning and control. Operating 2 switches is a whole lot easier than 6 to 8 buttons, instant positive feedback informs the operator what is happening, and if a correction is needed an opposite switch movement is all that is needed without the need to look at the control box and to work out from the various options which would be the appropriate next action to try.
Depending on your capabilities it would probably be a good time to open the gearbox, wash it out, and replace the grease.
Easiest to jack up the caravan and remove wheels. Undo two 8 mm (13 spanner) hinge bolts of Caravan Mover motor unit, hinge down, and unclip from pusher bar.
Undo two m6 countersunk cap screws that secure the gearbox onto the chassis plate. Most often these should be replaced as they have to be chiseled in the unscrew direction to release them.
On later units, these screws are covered with tape in order to prevent the driver hole from getting clogged, peel back as necessary.
The motor gearbox then separates from the roller.
The gearbox end plate can then be removed, 4 x screws, revealing the gears.
Wash out with petrol of turpentine, dry then re-grease, don’t overfill. Reassemble in the reverse order..
We have tried to make our unit as water-resistant as possible, through the installation of “O” ring seals ect.. Should water get into the unit through an extended period of being submerged, the unit will not fail for some time. We recommend that you strip down and clean out the motor gearbox when convenient.
When changing tires please ensure that afterward there is a minimum clearance of 15mm between the caravan mover roller/drum and the tire. Adjust the Caravan movers if necessary, by loosening the bracket bolts and sliding the unit.
The function of the Caravan Mover is to move the caravan in ideal conditions on hard surfaces, for example, driveways and parking areas.
However, the benefits of being able to move one's caravan single-handed, motivate use in other situations, where conditions are less than ideal, for example, campsites, and in particular coastal sites which are beautifully grassed, over effectively beach sand.
The limitation in these situations is almost all ways the jockey wheel performance.
The size of the wheel and the weight it supports are the main culprits to contributing to the amount of effort that the Caravan Mover has to provide.
Air conditioners and other loads on the front of the Caravan, tents, gas bottles, etc, all add significantly.
If the jockey wheel sinks into the supporting surface, the Caravan Mover WILL NOT MOVE THE CARAVAN happily, maybe it will do this for a short while, but the overload WILL EVENTUALLY CAUSE A FUSE TO BLOW, effectively the safety link.
Excessively hard tires also contribute to the load on the Caravan Mover, which will reduce the moving effort capable by the Caravan Mover. My personal ideal is 2.5 Bars.
If you are experiencing problems on a soft site as envisaged above, get a few people to climb into your caravan and stand in the rear. Not too many to cause an overbalance. In this way, the weight supported by the jockey wheel will be reduced and make the going easier for the Caravan Mover.
The jockey wheel needs to be able to rotate freely to allow "caster action" or rotating to be in line with the required rolling direction.
When turning the caravan, the opposing torque created by the rolling load offered by the jockey wheel is significant, due to the distance that it is from the center of rotation.
