各省、市、区交通厅、局: 一、民间运输是公路运输的一个重要组成部分。畜力车在陆上民间运输工具中,载重量最大。效率最高,占用劳动力最少。目前不仅在东北、华北、西北、华中等大部分省区普遍使用,自推行耕牛和骆驼拉车以来,畜力车在全国其他地区也逐渐代替人背肩挑和人力车辆等运输方式,成为公路运输中一支主力军。根据全国国营、运输合作社和人民公社专业运输队的畜力车估算。如果把现有的车辆效率平均提高50％每年即可增加约二十亿吨公里的运量可以大大节省农村劳动力。因此,千方百计地挖掘畜力车的潜在力量、具有十分重要的意 Transportation departments and bureaus of all provinces, municipalities and autonomous regions: 1. Private transport is an important part of road transport. Animal vehicles in land-based civilian transport vehicles, carrying the largest load. Highest efficiency, occupy the least labor. At present, not only is it widely used in most northeast, north, northwest and central China provinces and autonomous regions, since the introduction of cattle-raising and camel-pull trucks, the animal-powered vehicles have gradually replaced people’s backpacks and man-made vehicles in other parts of the country to become roads Transport in a main force.

Increasing the efficiency of existing vehicles by 50% on average and increasing the transport capacity by about 2 billion ton-kilometers annually can greatly save the rural labor force. Therefore, it is of great importance to do everything possible to tap the potential force of the animal car
