Robot Trolley 4500 G3 Caravan Movers - Black

Work off your trailer's loaded weight, not its empty weight. The 1500RS G5 handles trailers to 1,500kg and is the lightest at around 20kg. The 2500RS G3 goes to 2,500kg and adds a speed-up mode that doubles the pace when you're crossing an open yard. This 4500 G3 goes to 4,500kg but runs at the standard speed only. So the biggest one is the strongest, not the quickest.

Most movers clamp motorised rollers onto your chassis rails and press them against the tyres. That works on a smooth driveway and struggles the moment you're on wet grass or loose gravel. The Robot Trolley drives on two rubber-profiled caterpillar tracks instead, which spreads the load and holds traction on grass, soil, gravel and sand. Where it still won't help you is deep mud or very soft sand: the tracks will spin, and the manual says so plainly.

The mover attaches to a bracket bolted to your chassis, and Robot Trolley note that some countries and some makes of caravan need a different bracket version. That's the one detail worth sorting before the unit turns up rather than after. Ring the store on 03 7056 6732 with your van's make, model and year and we'll confirm which bracket you need.

There's an automatic brake that engages the moment the motor stops, and on flat ground it holds. On a slope with the nose pointing downhill it will slow the trailer rather than pull it up dead, and whether it stops completely depends on your weight and the gradient. That's normal for the class and it's why the manual tells you to have wheel chocks ready. Treat the mover as a positioning tool on level ground, and chock the wheels the way you always would.

The pack is a quick-swap lithium unit, so a second battery is the cheapest way to double your working time. The charger runs a red light while charging and turns green when it's done. If the van sits for more than two months, run the mover for a few minutes and charge it back to green: lithium packs that sit flat for a season lose capacity you don't get back.
