AL-KO Mammut S21 Single-Axle Mover System

Those who want to position their caravan or trailer in the right place need excellent driving skills, strong helpers, or of course the AL-KO Mammut manoeuvring system. With the Mammut system, you can position your caravan or trailer precisely to the centimeter.

Type S21

You choose the type S21 under the following conditions:
- Max weight caravan: 2250kg
- Distance from axle to inner side of the tire is at least 130mm and at most 180mm.
- The height of "a" or "b" (see diagram), is greater than 184mm. If you want to mount your manoeuvring system for your axle, look at "a", if it's behind your axle, look at "b."
- You want to mount your manoeuvring system in front of or behind your axle, in front or behind your wheel is both possible.
- There is NO 'M' stamped on your chassis in front of or behind the axle.

Remote Control with Joystick

AL-KO Mammut is the only manoeuvring system with joystick control. Unlike a push-button system, the joystick system allows you to fully and smoothly steer, accelerate, and decelerate. With the very user-friendly soft start/soft stop system, you can move your caravan or trailer to your desired position without jerks or interruptions. You aim the remote control at your caravan or trailer and then use your thumb to determine the direction and speed. When you release the joystick, the caravan comes to an immediate stop and the wheels are locked. Especially useful on slopes and uneven terrain. In addition, your caravan or trailer can be steered and turned a full 360° degrees. It can also rotate completely around its own axis.

Optimal Security

To prevent accidental activation of the manoeuvring system or the remote control, the system must be released before use. To do this, you move your remote control past a sensor near your coupling. The system can then be used until it is switched off. After switching off, the system must always be released again.

Powerful, Stable, and Reliable

The powerful Mammut drive units ensure smooth, stable, and reliable driving of your caravan wheels. Each drive unit has two electric motors for driving the caravan wheels. One motor is responsible for driving the wheels using the drive rollers. The other motor is responsible for pressing the drive rollers against the tires. The electronic control of the pressure of the drive rollers ensures optimal grip on the tires. The powerful operation enables your caravan or trailer to move not only on flat terrain but also on slopes up to 28%. Ideal for mountainous terrain or a hilly campsite. In addition, the drive is powerful enough to overcome obstacles up to 4 cm high (values for a single-axle caravan). Stones or curbs are therefore no problem. Climbing ability: 15% at 2000kg, 17% at 1800kg, 28% at 1200kg.

Solid Housing

The drive units of manoeuvring systems have a lot to endure, such as splash water, snow, ice, dust, or flying stones. Thanks to the solid aluminum housing, your Mammut system is well protected against external influences (protection class IP65). Despite the solid aluminum housing, the complete system, including the transverse beam for top installation, weighs only 42kg for single-axle caravans.

Maximum Ground Clearance

An AL-KO chassis with a stamped 'M' in the chassis beams (single-axles from model year 2010) is equipped with mounting holes for the Mammut system. This means that the transverse beam necessary for stability does not take up any space under the chassis. This means that your ground clearance is fully maintained. This can prevent damage to your manoeuvring system.
