【正文】 , and many other advantages. At present, swinging arm type truck has a wide range of applications, garbage transportation already affected every part of our lives for the development of national economy, has an important significance. This paper introduces the modification of swing arm garbage design explains. For car, swinging arm device, hydraulic system and affiliates carried on the detailed design, and the different schemes are pared and analyzed, and guarantee the swing arm advanced and practical rolloff garbage trucks. Describes the modification process of rolloff garbage trucks swing arm of the problems and related to the working principle of special equipment, and the vehicle performance is analyzed.
