A single bucket excavator is a self-propelled excavator that uses a single bucket to dig soil or ore. Single bucket excavator is mainly composed of engine, hydraulic system, working device, traveling device and electric control. The hydraulic system consists of a hydraulic pump, a control valve, a hydraulic cylinder, a hydraulic motor, a pipeline, and a fuel tank. The electrical control system includes a monitoring panel, an engine control system, a pump control system, various sensors, and solenoid valves. During operation, the bucket is turned to the unloading point to unload the soil after the full bucket is excavated, and the empty bucket is returned to the unloading point for periodic operations. Single bucket excavators are widely used in construction, road construction, water conservancy, electric power, mining, oil, natural gas and national defense construction, and generally cooperate with dump trucks.
Single bucket excavators are widely used in construction, road construction, water conservancy, electric power, mining, oil, natural gas and national defense construction, and generally cooperate with dump trucks. Its main uses are as follows: excavation of building foundation pits in construction projects, demolition of old buildings, etc .; excavation of road cuttings in road construction projects, filling of embankments, bridge foundation pits, and various pipeline trenches on both sides of urban roads (launch Pipeline trench, gas, natural gas, communication, power pipeline trench, etc.); excavation of trenches and rivers in water conservancy projects, and excavation operations for stripping topsoil and minerals in open-pit mining projects; after replacement of working devices It can also be used for pouring, lifting, installation, piling, ramming and pile pulling.
The single bucket excavator is mainly an earthmoving machine. In construction engineering, single bucket excavators can excavate foundation pits, trenches, and clear and level the site. It is a very important machinery and equipment in earthwork construction. After changing the working device, it can also perform tasks such as crushing, loading and unloading, lifting, and piling.
The power unit of single bucket excavator includes diesel engine drive, electric drive (called shovel), steam engine drive and compound drive. Its transmission includes mechanical transmission and hydraulic transmission. Its walking devices include crawler, tire, track, walking and floating. The turntable can make 360 ° full or partial rotation. Commonly used in civil construction are diesel-driven, full-slewing, hydraulic transmission excavators.
