The weight transfer makes the carriage much safer to use and improves the driving comfort.
The weight resting on the hitching gear is distributed on the 4 wheels of the tractor and the shocks are absorbed by the hydropneumatic hitching suspension.
Triple-axle vehicles have the front lifting axle in their standard equipment.
An inner partition is bolted at the front of the tank (1/3) and allows to keep as much weight as possible on the eyelet when spreading, thereby improving grip and drive.
The volumes before and behind the partition are simultaneously set under depression in order to fill the tank completely.
The volume behind the partition is pressurized (rear volume) in order to keep the front part filled.
When the slurry level reaches the lower edge of the partition, an air in-draft is created towards the front part in order to empty it.
This weight transfer system is particularly suitable to tankers fitted with a rear spreading implement.
