第十九冶金建设公司建筑研究所与特种公司最近研制成功一种公路铁路两用多功能线路施工机械(PZ-151型,见附图)。适于在大型厂矿铺设分散、短线铁路之用。该机主要优点是:体积小、重量轻、耗用功率小、生产效率高。行走部分采用机械传动,由轮胎驱动,可在公路上行驶,自行开到施工工地,并可从平交道口和轨道端部自行上下铁道。机器前后端装有液压升降钢轮,供铁道行驶导向之用。机身中部装有夹轨器,保证作业
The nineteenth Metallurgical Construction Company Institute of Building Research and Special Company recently developed a road and railway dual-purpose multi-purpose line construction machinery (PZ-151 type, see attached drawing). It is suitable for laying scattered and short-term railways in large factories and mines. The main advantages of this machine are: small size, light weight, low power consumption and high production efficiency. The walking part adopts mechanical transmission and is driven by the tires. It can be driven on the highway, open to the construction site on its own, and can be traversed from the level crossing and the end of the track. The front and rear ends of the machine are equipped with hydraulic lifting steel wheels for railroad guidance. The middle of the fuselage is equipped with a rail clamp to ensure operation
