近年来,我国自卸车的发展向轻型化和重型化两极发展。重型自卸车里尤其7—8米长车箱8X4方箱自卸车发展速度快,需求年递增幅度较大。但就目前国内常用的自卸车而言,该系列自卸车的上装结构存在着两个无法克服的缺陷——重心高和自重大。长期以来,长货箱自卸车只是在国内现有产品上改良,无法从根本上解决这些因车体结构引起的问题,这导致车辆的使用成本居高不下,寿命偏低,在一定程度上制约了自卸车发展。
In recent years, the development of dump trucks in our country has been developing both lightly and heavily. In particular, the heavy-duty dump truck 7-8 meters long 8X4 square-box truck dumper development speed, demand increased by a larger margin. However, for the current domestic dump truck, the dump truck body structure there are two insurmountable defects - high center of gravity and heavy weight. For a long time, long-tipped dumpers only improve on the existing domestic products and can not fundamentally solve these problems caused by the structure of the vehicle body, which leads to the high use cost of the vehicles, low life expectancy and to some extent restriction Dump truck development.
