挖掘机是一种集挖掘、装载、卸料于一体的高效土方工程机械。据测算,一台斗容量1米3的挖掘机,其台班生产率相当于300~400人的日工作量,被农民广泛用于农田冬修水利、鱼塘开挖和参与城市道路、市政、建房基础坑的开挖工程之中,对减轻体力劳动、加速工程进度、提高劳动生产效率起着十分重要作用。一、挖掘机的分类1.按行走装置不同可分为履带式和轮胎式。履带式稳定性好,应用广泛。2.按传动方式不同可分为机械式和液压式。液压式
Excavator is a set of excavation, loading, unloading in an efficient earthmoving machinery. It is estimated that a bucket capacity of 1 m 3 excavator, its class productivity equivalent to 300 to 400 people daily workload, is widely used by farmers in winter farmland water conservancy, fish pond excavation and participation in urban roads, municipal services, Construction of foundation pit excavation project, to reduce manual labor, speed up the progress of the project, improve the efficiency of labor production plays an important role. First, the classification of excavators 1. By walking device can be divided into different types of crawler and tire. Tracked stability, wide range of applications. 2. According to different transmission can be divided into mechanical and hydraulic. Hydraulic
