The AL-KO 4WD Mammut TM4xx is for caravans with Twin axle caravans (4 WD). 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 (2.4 GHz) with joystick.
This mover has an operation with comfort. Thus making it possible to adjust the caravan a little left or right while manoeuvring forwards and backwards. You can also adjust the driving speed dynamically. 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 4500 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 belt. Before use, you have to release the safety switch. 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 3000 kg /15%. 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 3000 kg. The actual weight of the mover itself (our measurement) without battery is approximately 74 kg. The mover is relatively low in weight.
