The AL-KO Ranger S21 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 (433 mhz) with push buttons. You can turn the caravan around the axle.
This is a semi-automatic mover. Actuation is done with hand crank. 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. 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 manufacturer recommends this mover for caravans up to 1500 kg /18%. We expect with our advise taking a short slope of 20% should be no problem, thus our advise with our set 2 for this mover is for caravans with a maximum weight of 1200 kg. The actual weight of the mover itself (our measurement) without battery is approximately 42 kg.
