AL-KO HY4

The Fully-automatic motorhome levelling system with unique, decentralised hydraulics concept, is setting completely new standards. The chassis experts from Kötz are presenting the most sophisticated, most innovative and safest steady leg system for motorhomes based on the Fiat Ducato X250 with AL-KO chassis (permissible overall weight up to a maximum of 6.0 tonnes). Completely new in Europe and this class of product is the close affinity with high-quality, long-lasting and robust heavy load technology from major US leisure vehicles. The idea behind AL-KO HY4: Each of the four steady legs on the motorhome has its own, independent assembly. This saves the laborious and time-consuming installation of hydraulic hoses along the entire length of the chassis and avoids any loss of storage space in the superstructure. And because all components in the fully winter-proof system are installed securely in the chassis, the risk of leaks or any oil contamination in the superstructure is eliminated.

Another benefit is the fact that the weight of the high-quality supporting system is distributed perfectly between the front and rear axles thanks to its decentralised, “load-friendly” design. In other words, the permissible payload in the rear storage space or rear garage, especially in the 3.5-tonne class, is less affected than with other support systems. This means that the overall vehicle’s centre of gravity is shifted downwards, which has a positive effect on driving safety and driving dynamics. Conversely, AL-KO HY4 acts as an immobiliser when thevehicle is stationary, providing protection against theft.

The general rules that apply to steady legs also naturally apply to the AL-KO HY4: the fully automatic supporting system, in which all of the components are connected perfectly to the chassis, compensates uneven ground and guarantees a safe, level position for the motorhome while camping. And not only that: comfort functions, some of which can be custom-programmed -such as lateral tilting of the vehicle when draining the tank or adjustment of preferred sleeping positions at every pitch thanks to the corresponding basic alignment of the motorhome -mean that AL-KO HY4 can be individually adapted to every vehicle and therefore perfectly to the user’s own wishes.

AL-KO Fahrzeugtechnik / Vehicle TechnologyThe system is operated easily and intuitively via a cabled remote control featuring state-of-the-art LED technology and a central electronics unit, designed for installation in the underfloor area. Excellent control performance, short response times from the telescopic cylinders and the option to transfer the entire product with the purchase of another motorhome without causing installation damage to the expensive superstructure of the previous vehicle add the finishing touches to this maintenance-free, high-end system.
