一、国外概况近年来西方各国竞相致力干轻小型搬运车辆的研究与开发,逐渐形成了一个分支,称为“厂区搬运车辆”,国内尚处于起步阶段,暂以“轻小型搬运车辆”命名。这类机种的基本特征是:起重量吨位小、运行速度低、工作频率低、结构简单、价格低廉、对作业环境的适 I. OVERVIEW OF OVERSEAS In recent years, all countries in the western countries have been competing for the research and development of dry and light handling vehicles, and have gradually formed a branch called “factory-handling vehicles.” China is still in its infancy and is named after “light and light handling vehicles”. The basic characteristics of this type of machine is: small tonnage lifting capacity, low speed, low frequency, simple structure, low price, suitable for the operating environment
