AL-KO AIR PREMIUM X4
Full air suspension for AMC chassis
(Front and rear axle(s))
Air-PREMIUM X4 is the latest development in air-suspension systems from AL-KO.
Air-Premium X4 provides unprecedented stability and comfort on any journey, and is particularly suitable for fragile loads & equipment, and / or passenger transport, such as emergency vehicles.
Four independent suspension systems (two on the front and two on the rear axle) work together to dampen vibrations from uneven driving surfaces, and ensure loads and passengers are safe and secure.
Fully air-sprung front axle struts with level sensors
An intelligent, electronic control system actively regulates and adjusts each system separately, according to the current load.
In addition to the unique and comfortable drive quality, the AIR-PREMIUM X4 keeps the vehicle level, independent of the load
without the driver having to do anything. The result: the highest
standards of ride comfort available today.
Compressor with electronic control
Fully air-sprung back axle with level sensors
Excellent ride comfort due to an electronic fully automated air-sprung system for front and back axle (4 circuit system).
Modern electronic controls coupled with 4 level sensors provide a constant level for your vehicle - independent of the load.
Lift/lower the whole suspension with the flick of a switch - possible up to speeds of 25km/h.
Front Axle: lifts circa 60 mm/lowers circa 40 mm
Back Axle: lifts circa 55 mm/lowers circa 65 mm
Optional Auto-Level Function Switch. When the vehicle is at standstill, it automatically adjusts its level within the springs margins to a horizontal level.
Optimised AL-KO high performance shock absorber with front and back axle flat tyre compensation
If during loading or unloading axle load differences occur, the drive level will be electronically regulated by air being pumped in or out of the spring air reservoirs - provided the ignition is switched on.
Dynamic differences in axle loads will not trigger the regulation process as they occur below the response time of the electronic system.
To ensure equal distance between chassis and road, four level sensors constantly measure spring movement and evaluate it electronically.
With the ignition on, the drive height is automatically adjusted between the front and back axle, according to factory setting.
This occurs independently from the load level.
STANDARD RAISE / LOWER FUNCTION
Raise / lower the entire chassis by pressing a button, while travelling at maximum speed of 25km/h.
Front Axle: lifts circa 60 mm/lowers circa 40 mm Back Axle: lifts circa 55 mm/lowers circa 65 mm
AUTOLEVEL FUNCTION (OPTIONAL)
Just by pressing a button, level the vehicle within the available axle spring stroke range independently in any position to a horizontal comfort level.
Maintenance-free air suspension system and trailing link axle(s)
Control electronics diagnostics.
Wide service network coverage.
USE Factory- and retro fitted with AMC chassis.
Based on Fiat Ducato, Peugeot Boxer and Citroen Jumper (X250 model) with 2 and 3 axles.
Arrows - on switch below lift and Lower whilst stationary and at speeds of up to 25 km/h.
The red button activates the optional Auto-Level function - the vehicle adjusts to a horizontal level at its pitch.
Air reservoir for quick response
With the ignition on, the drive height is automatically adjusted between the front and back axle according to factory setting. This occurs independently from the load level.
