Description

No more inclined angles, no more unsteady ground under the feet. With HY4, the new, innovative support system from AL-KO, you can level your motorhome quickly and easily in the desired standing position. The new weighing function helps to avoid incorrect loading and dangerous overloading – simply by using your smartphone.

The system is available for all vehicles with an AL-KO chassis, as well as for X250/290 motorhomes and vans on a Ducato/Jumper/Boxer chassis. Also available for Mercedes-Benz VS30 motorhomes on AL-KO SLC and AMC chassis as well as original chassis and for Mercedes-Benz VS30 RWD panel vans.

The AL-KO HY4 and HY2 are the first hydraulic lift support systems to have a clearance certificate from Mercedes-Benz. This certifies the safeguarding of Mercedes-Benz brand values and basic vehicle characteristics with regard to safety, operational stability, driving dynamics, assistance systems, legal requirements and other important features. True to the AL-KO brand promise "Quality for life", our engineers think even further ahead.

Your benefits

  • Clean and space saving – no more bulky hydraulic components inside the vehicle.
  • Optimum weight distribution – thanks to four independent hydraulic assemblies mounted directly on the chassis.
  • Intuitive LED remote control – millimetre-precise levelling in only one minute.
  • High professional quality – certified mounting bracket from chassis specialists.
  • With clearance certificate from Mercedes-Benz

New: weighing function and app control

The system measures the gross weight and the respective axle load via measuring points on the longitudinal and transverse axes. This makes complying with weight limits easy and ensures payloads in the vehicle are optimally stowed. Control and display are via the AL-KO 2LINK app, which can be downloaded free of charge onto your own smartphone. This is based on installing the AL-KO 2LINK box with a Bluetooth interface.

Following this upgrade, it is even possible to level the vehicle via the 2LINK app. The smartphone user interface is similar to the standard remote control interface, and thus still very easy to use.
