MUK 303 - Kröger Nutzfahrzeuge [EN]

An indestructible heavy worker which you can configure totally to meet your operational requirements. In a short and more compact design also suitable for trips in combination with a second trailer or in the longer design for solo use as a large volume vehicle. Our trough shape with angled side walls allows a flexible design of the trough dimensions both in the height and also in the length. Thanks to the angle system, the empty weight can be significantly reduced compared to conventional ribbed designs.
