The Truma Mover SeR (2009 - 2017) is for caravans with single axle caravans. The electronics have a softstart and stopfunction. This makes manoeuvring the caravan gently and has less effect on the chassis. Manoeuvring is done with a remote control (868 MHz) with push buttons. You can turn the caravan around the axle.
The swiveling of the rollers towards the tire is fully automatic with the pressure on the tires controlled by the electronics.
The pressure builds up to 5600 Nm. The distance traveled when swiveling is 4 cm. De rollen staan ongeveer 2 cm van de band afgesteld, de druk van de rol in de band is dus maximaal 2 cm. The actuator motor automatically stops as soon as the pressure is sufficient or as soon as the mover has been pushed fully forward. In case of a completely discharged or defective battery, the mover can easily be removed from the beltwith an included special key. Before use, you have to release the safety switch. On the integrated indicator can be read if the mover is correctly engaged against the tires. The mover has a worm wheel transmission that prevents the caravan from rolling back on a slope.
The actual weight of the mover itself (our measurement) without battery is approximately 33 kg. The mover is low in weight.
