Volvo Trucks - Tandem Axle Lift function

Tandem Axle Lift is available for the Volvo FM, Volvo FMX, Volvo FH and Volvo FH16.
The new function Tandem Axle Lift makes it possible to disengage and raise the second driven axle. This provides better road grip and up to four per cent lower fuel consumption when the truck is driven without a load.
By replacing the differential in the first driven axle with a dog clutch, the second driven axle can be disengaged and raised. The driver thus has access to both the power and capacity of two driven axles (6X4) and also the better manoeuvrability of a single driven axle (4X2). What is more, driving with the second driven axle raised also cuts the turning circle by a metre and imposes less wear on tyres and suspension systems.
Tandem Axle Lift also offers the driver better comfort when the truck is driven empty, which in many cases corresponds to 50 per cent of the operating time. The in-cab noise level is lower and steering wheel vibration is reduced when only the tyres of one drive axle are in contact with the road.
