[Industrial applications]

 This proposal relates to a high-efficiency dedicated snow removal truck that combines three types of snow removal equipment for the purpose of all-oil type snow removal trucks used for snow removal work on roads.

[0002]

[Prior art]

 Conventionally, in the case of a snow removal-only vehicle having this type of snow removal device, the side wings are installed in front of the grader even if three types of devices are installed as shown in Fig. 1 of Japanese Utility Model Laid-Open No. 3-93817. Therefore, in the case of simultaneous construction, it is not possible to treat the snow discharged by grader with side wings. In Japanese Utility Model Application Laid-Open No. 63-31119 and Japanese Patent Laid-Open No. 52-15146, only two types of devices are used, and a combination of three types is impossible. Further, in the case of a motor grader, a side wing device is provided as in Japanese Patent Laid-Open No. 57-15708, but simultaneous work by two types of devices is limited, and high speed snow removal work is not suitable.
