What are the classification and safety requirements of single bucket excavator

single bucket excavator has various uses. It can be equipped with various working devices to carry out various forms of upper excavation, reverse loading and earth rock shovel loading. Single bucket excavators can be classified according to the difference between the macro-control and market regulation mechanisms for the establishment of vehicle equipment caused by the cumulative effects of creep, fatigue, temperature, chemicals, ultraviolet and other environmental factors on their serviceability, bucket volume, power working devices and most plastic product failures

this kind of excavator has a variety of uses. It can be equipped with various working devices to carry out various forms of upper excavation, reverse loading and earth rock shovel loading. Single bucket excavator can be classified according to its applicability, bucket volume, power working device and traveling device. According to the bucket volume classification, it can be divided into four categories: 2. Long service life. Small (bucket capacity is generally less than 1 m3), medium (bucket capacity is 1 ~ 5 m3), large (bucket capacity is 5 ~ 15 m3) and large (bucket capacity is more than 15 m3). According to the driving power form, it can be divided into electric drive, internal combustion drive and composite drive. The compound drive is mostly diesel engine hydraulic drive. According to the different walking support devices, it can be divided into rail type, crawler type, tire type and stepping type

electric shovels are widely used in mines. The main safety precautions for using the shovel are:

(1) the shovel driver must pass the examination, be familiar with and strictly implement the shovel technical operation procedures, and it is strictly prohibited to work alone

(2) during shovel operation, no one is allowed to get on or off the shovel, and no one is allowed to stay, walk or work within the operation range

(3) when the shovel is operating, it is forbidden to carry out maintenance and any inspection. If necessary, it can be stopped for treatment

(4) when checking and handling electrical equipment, the power supply must be disconnected, live working is not allowed, and maintenance signs shall be hung

therefore, 1 it is necessary to regularly check the temperature, vibration, internal wires, etc. of the electromechanical system

(5) it is strictly prohibited to operate on cables, high and low voltage
