一、液压挖掘机的基本特点 单斗液压挖掘机是在机械传动式正铲挖掘机的基础上发展起来的高效率装载设备。该设备主要由工作装置、回转装置和行走装置三部分组成。在液压挖掘机的动力装置与工作装置之间,采用了液压传动系统。 液压挖掘机的工作装置,其动臂结构有铰接式和伸缩臂式。回转装置有全回转和非全回转。行走装置可分为履带式、轮胎式、汽车式和悬挂式、拖式等。矿用液压挖掘机通常为履带式。
First, the basic characteristics of hydraulic excavators Single bucket hydraulic excavator is a mechanical transmission type shovel excavator is based on the development of high-efficiency loading equipment. The equipment mainly consists of working device, revolving device and walking device. Between the hydraulic excavator power plant and work equipment, using a hydraulic drive system. Hydraulic excavator work device, the boom structure has a hinged and telescopic boom. Rotary device with full rotation and non-full swing. Walking device can be divided into crawler, tire, car and hanging, trailing and so on. Mining hydraulic excavators are usually tracked.
