ATJ International supply Thwaites articulated 4x4 site dumpers to New Zealand contractors. From a 1 tonne hydrostatic hi-tip to a manual 10 tonne front tip, we have the dumper that will do the job. In Europe, Thwaites distinctive yellow dumpers are one of the most common sights on any construction site; their versatility means they can handle anything from major infrastructure to pipe line, rail or utility projects as well as general building projects. Dumpers offer the most economic earth moving option for small to medium sized site work. They can be easily manoeuvered with minimal impact on the surrounding site, are relatively compact and offer accuracy and safety to the operator and others working on site;  the open cab offers high visibility (360° view) and easier communication.
