According to the way of work
Single-bucket excavators and multi-bucket excavators, common excavators are single-bucket excavators, and only bucket-wheel excavators are used in large mines, with many buckets and rotating operations.
According to drive mode
Internal combustion engine drive, electric drive, compound drive (hybrid)
by way of walking
tracked and tires
According to the working device
Front and Backhoes
The whole machine can be divided into three parts structurally: chassis assembly, working device assembly, and upper platform assembly.
The composition and function of the chassis assembly: 1. Support the weight of the upper part of the excavator. 2. Power source and actuator for walking and steering. 3. Support the reaction force of the working device during excavation.
The main components of the chassis: 1. The lower frame body (welding parts), 2. Four wheels and one belt (guide wheels, driving wheels, supporting sprockets, rollers, crawlers). 3. Dozer blade and cylinder. 4. Central rotary joint. 5. Swivel raceway ring (slewing bearing). 6. Travel reducer and motor.
A brief summary consists of three parts: engine, hydraulic system, and electrical components! The hydraulic system consists of: hydraulic pump, distributor, rotary, walking, and pilot control parts
Standard big and small booms, excavator extended booms, and extended big and small booms (including two-section extended booms and three-section extended booms, the latter is the demolition boom). 2. Standard buckets, rock buckets, reinforced buckets, gutter buckets, grid buckets, screen buckets, cleaning buckets, inclined buckets, thumb buckets, and trapezoidal buckets. 3. Bucket hook, rotary hydraulic grab, hydraulic claw, pliers, wood grab, mechanical claw, quick change joint, ripper. 4. Excavator quick connectors, excavator cylinders, breakers, hydraulic shears, hydraulic rammers, vibration hammers, bucket teeth, tooth seats, crawlers, supporting sprockets, and supporting wheels.
