Composition and Included Components of Excavator Parts

Excavator parts are mainly composed of two categories: mechanical parts and electronic parts.

1. Mechanical Parts: Pure mechanical components that provide power support, mainly including hydraulic pumps, grabs, booms, crawlers, engines, etc.

2. Electronic Parts: The drive and control system of the excavator, used to drive and properly operate mechanical components, mainly including ECUs, hydraulic flow controllers, angle sensors, diesel gauges, fuses, ignition switches, oil suction pumps, etc. Mechanical components and the drive control system are complementary. The electronic control system drives and coordinates the efficient and continuous operation of all mechanical components. The status of the mechanical system is fed back to the electronic control unit via electronic components, thereby coordinating the excavator’s operation more effectively to achieve maximum working efficiency.

Included Components of Excavator Parts:

1. Standard boom and arm, extended boom and arm, lengthened boom and arm (including two‑section extended arms and three‑section extended arms; the latter is also called demolition arm);
