Here you can see the actual mechanism at work.

The load carried is angled (apporx 45 degrees) as it comes off the rails and as it makes contact with the ground the vehicle slowly moves forward keeping pace with the hydraulic arm until the load is safely on the ground.

The arm is retracted and the vehicle is ready to collect another load.

The most popular forms of load carried are the drop side cargo body which covers a multitude of roles, and the tanker which can be used to supply Fuel Oil or Gas or water be it drinking or as used for fire fighting.

As you can see both units emply the A-Frame arrangement onto which the Multi-Lift arm connects.

With a drop side body it the unit can also double up and be used as a tipping body.

By simply opening the rear side door and raising the arm, the unit is in effect working as a standard tipper body whilst still being able to fulfill multiple roles by simply changing pods.
