Product Details

Aiweiya Minibagger Kubota Engine 3 ton small excavator

The operating principles of a 3-ton mini excavator include the following key areas: power system, hydraulic system, control system, and work unit. Understanding these principles helps to better operate and maintain the mini excavator.

1. Power system

The power system is the core of the excavator, providing it with the required mechanical energy. A mini excavator is usually equipped with a diesel engine that drives a hydraulic pump that supplies pressurized oil to the entire hydraulic system. The engines of modern mini excavators usually have fuel economy and low emission characteristics to meet environmental requirements.

2. Hydraulic system

The hydraulic system is a key component of the mini excavator, which is responsible for converting the mechanical energy of the engine into hydraulic energy and transferring the energy to each actuator through the hydraulic circuit.
