随着高速公路建设的发展,30～50m大跨度桥梁被广泛应用。DJ50/160步履型伸缩臂式单导梁架桥机就是为架设公路桥梁50m及以下跨度预应力钢筋混凝土梁片而设计制造的,是中铁三局邯郸工程机械制造有限公司在多年设计、制造公路架桥机的基础上开发出来的新一代架桥机。该机结构新颖、性能优良、自动化程度高,使用维护方便;整机采用伸缩臂式导梁引导过孔作业,安全可靠;机臂能上下升降、前后伸缩、左右摆头,整机可横向移动,实现全幅梁片一次落梁到位,并能连续架设直线桥、斜交桥和曲线桥。
With the development of highway construction, 30 ~ 50m long-span bridges are widely used. DJ50 / 160 walking telescopic single-girder bridge erecting machine is to set up a bridge 50m and below the span of prestressed reinforced concrete beam designed and manufactured, is the third railway station in Handan Construction Machinery Manufacturing Co., Ltd. in many years to design, manufacture of highways Bridge machine based on the development of a new generation of bridge machine. The machine has the advantages of novel structure, high performance, high degree of automation and convenient use and maintenance. The machine adopts a telescopic guide beam to guide a through hole operation, which is safe and reliable. The arm can be lifted up and down, , To achieve a full beam beam fall in place, and can be erected straight line bridge, ramp bridge and curved bridge.
