YZD4型多功能压路机兼有静作用式、振动式和振荡压路机的功能。在同样的压实效果前提下,比静作用压路机节约钢材近50%,降低能耗约40%。该机具有体积小、重量轻、激振力大、结构简单、操作方便、压实效果好等特点。主要用于基础压实、罩面、公路修补,特别适合高等级公路施工要求。该机日前由安徽公路机械厂研制成功,通过省级鉴定,外形见图1。 The YZD4 multi-function roller combines the functions of static, vibratory and oscillating rollers. With the same compaction effect, nearly 50% of the steel is saved compared to the static roller and the energy consumption is reduced by about 40%. The machine has the characteristics of small size, light weight, large excitation force, simple structure, convenient operation and good compaction effect. Mainly used for basic compaction, covering, road repair, especially for high-grade highway construction requirements. The aircraft was successfully developed by the Anhui Highway Machinery Factory. It passed the provincial appraisal and its appearance is shown in Figure 1.
