The automatic levelling and support system

The AL-KO HY4 ­hydraulic steady leg ­system ­ensures stability in the living area for motorhomes up to 6 ­tonnes. ­AL-KO HY4 automatically takes care of the millimetre-accurate ­levelling of the ­motorhome at the pitch in about one minute. To ensure that no damaging forces act on the superstructure, the legs are always extended in pairs on the longitudinal or transverse axis.

Clean and space-saving

In contrast to other steady legs systems, where the support legs are supplied via hydraulic lines by a centrally located pump with an oil tank, each support leg of the AL-KO HY4 has its own pump with an oil tank. This can be mounted flexibly in the immediate vicinity of the leg. This reduces the installation effort and eliminates the need for components that block storage space inside the vehicle. Therefore, it is one of the most ­modern ­hydraulic systems on the market.

Once purchased, the steady leg system can be easily reconfigured when you change vehicles so that your new ­motorhome will also have a steady footing. AL-KO HY4 comes with the usual, excellent   AL-KO quality, is durable, robust, maintenance-free and quiet.

Intuitive and easy...

to use the AL-KO HY4 via the remote control in the ­driver's cab. Easy to understand buttons ­control the steady legs for manual and automatic ­levelling. In addition, two additional functions can be freely programmed in: for example ­your personal sleeping position and the ­tilt for emptying the waste water tank. Thanks to the built-in inclination sensor, the system informs in advance whether levelling is possible in the event of severe inclination.
