The chassis with BDF frame
Standard BDF frames for trucks can be defied as additional equipment at the truck manufacturer (parking height and length of swap body) and a fitting, full air -suspended chassis will be found. Major data is the wheel base (due to charge axle load), the chassis frame height RH, the frame overhang at the back and the tires.
With the aid of this, the height and the function of the BDF frame (with or without adjustable height) will be chosen.
Important for the right choice is the combination of the ride height of the chassis (frame height RH plus overall height of the BDF frame B) and the parking height of the swap bodies in the fleet.
