Super Tipper Truck Concept Published in Cars, Work Tags: truck 26 Mar Because tipper trucks in our days can only unload their cargo just one way and the driver should maneuver the car very carefully, Haishan Deng designed a concept where door access is on all four sides. The truck have the possibility to dump its junk in any direction the driver wants. Each set of wheels has its own powered motor and independent suspension. Independent suspension allows it to climb with ease. You can see how dirt can be dropped in any direction.
