Description

The AL‑KO MAMMUT manoeuvring system makes light work of positioning your trailer. Whether on rough ground or slopes, the system moves the vehicle easily and effectively. With just your thumb and without having anyone to help you.

Your benefits

  • Easy, smooth and infinitely variable manoeuvring thanks to joystick with soft start and soft stop technology
  • Immediate stop on inclines: Release the joystick and the trailer is braked to a halt immediately
  • Electric control of the drive rollers. The electronics make sure that the maximum permitted contact pressure is always applied. That means top grip under all conditions
  • Rotation on the spot up to 360° – with intuitive one- handed operation via the joystick
  • Powerful movement: Easily moves up inclines of up to 28% and can overcome kerbs and obstacles up to 4 cm high
  • Maximum contact pressure applied to the wheels by the electric wind on function of the rollers
  • Maximum ground clearance thanks to flat design
  • Lightweight, without battery from 32 kg (SA)
  • Perfect protection of the chassis thanks to solid, computer-optimised cross members
  • Robust solid metal housing with metal gear unit
  • No TÜV registration required thanks to general operating permit
  • Made in Germany
  • Power consumption: Peak current 120 A (SA), quiescent current max. 5 mA
  • CAN bus-compatible
  • Infinitely variable speed control via joystick (max. speed approx. 0.5 km/h)
  • LED displays in the hand-held radio transmitter for: System ready, maximum gradeability reached, maximum drive temperature reached, battery status of hand-held transmitter, battery status of drive
  • Manual emergency turn of positioning drive
  • Sturdy drive rollers that protect the tyres
  • Diagnostic capability at the diagnostic interface in the vehicle

Optimal grip

Two motors are integrated into every drive unit: one for the positioning drive and one for the wheel drive. One push of the button on the remote control and the sturdy sandblasted drive rollers mounted in double bearings press against the wheels. The permanent electronic control of the contact pressure ensures optimum grip under all conditions. The second motor in the drive housing is responsible for the wheel drive.

Fingertip manoeuvring

Only the AL-KO MAMMUT CTRAIL offers a manoeuvring system with joystick control. Contrary to button operation, you can use one hand to easily steer, accelerate and brake.

Playing it safe

To prevent inadvertent operation, the system has to be enabled via magnetic switches. The remote control is simply held against the sensor on the drawbar to activate the system.

Simple installation 

Weld the two drives to the frame via the cross member and adapter plates. Connect positive/negative cable to the battery. Mount magnetic switch on the drawbar. Ready to go! The complete control unit on the single-axle variant is protected in the MAMMUT and does not have to be installed and wired separately. In the tandem version, a small controller the size of a cigarette packet is additionally mounted to protect against moisture.

Battery/charger

We recommend maintenance-free AGM batteries with suitable and matching charging technology. For trailers with a permitted gross weight up to 1,800 kg without additional consumers (e.g. light, water pump), AGM batteries with a capacity of at least 80 Ah. AGM batteries with spiral cell technology should have a capacity of at least 66 Ah (SA without autonomy) or 75 Ah (SA with autonomy).

Jockey wheel

Manoeuvring drives may overload jockey wheels on soft ground. Narrow wheels can dig into the soft or loose ground. Consequently, AL-KO recommends:

  • Use a tall, wide wheel
  • Use a sturdy jockey wheel with a load capacity of more than 200 kg, e.g. the AL-KO Premium jockey wheel

Note

MAMMUT CTRAL can only be ordered as original equipment from dealers or body manufacturers!
