The clever manoeuvring system for commercial trailers

The AL‑KO MAMMUT CTRAIL manoeuvring system makes light work of positioning your trailer with millimetre precision. 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.

Optimum 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 CTRAIL and does not have to be installed and wired separately.

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
