Small excavators are construction machinery mainly used for excavating earth and stone,and are widely used in soil and construction sites of various construction projects.There are many varieties of small excavating machinery.According to their working methods,they can be divided into periodic working type and continuous working type.The periodic working type includes single-bucket small excavators and backhoe loaders;the continuous working type includes multi-bucket small excavators,multi-bucket machines and tunnel boring machines.wait.The single bucket excavator is the most widely used mechanical equipment among small excavating machinery.This section will focus on the small bucket excavator.
A small excavator is a machine that uses a bucket-shaped working equipment to excavate soil or other materials,or to break away from the soil.It is divided into two types:crawler type and tire type.We often see giant machines showing off their skills on construction sites.The appearance design is a bit like a robot.Most of them are crawler-type small excavators.Small excavators are composed of three parts:working equipment,rotating equipment and operating equipment.Hydraulic crawler-type small excavators use volumetric hydraulic pressure between the power system and working equipment.The transmission system directly controls the movement status of each system organization,so that the small excavator during excavation can be divided into two types:full hydraulic transmission and non-full hydraulic transmission.
If the movements of key mechanisms such as excavation,rotation,and walking are all hydraulic transmission,it is called full hydraulic transmission.If the action of one of the organizations adopts mechanical transmission,it is called non-full hydraulic transmission.Normally,for small excavators,the working equipment and rotating equipment must be hydraulic transmission,and only the traveling mechanism can be hydraulic transmission or mechanical transmission.
The working equipment structure of a small excavator has different types of boom structures,such as articulated and telescopic boom.Rotary equipment is also divided into full rotation and non-full rotation.Circulation equipment can be divided into crawler type and tire type according to different structures.
