With the strengthening of the traffic management department's governance of overloading transportation, under the weight-based charging system, the lightweighting of trailers has become a trend. At the same time, with the improvement of safety awareness, how to make side-tipping dump semi-trailers both light and safe has always been a difficult problem in the trailer industry.

Shandong Hezhong's side dump trailer uses Mallory type (T type), single cylinder floating connecting rod type (F type), or front direct top type hydraulic lifting mechanism. Hydraulic parts are from reputable domestic or international brands, which is always inspected and used strictly according to the requirements of quality system documents to ensure best performance.
