Once the formal installation phase begins, the mini excavator installers act like "precision surgeons," moving among the steel components and using their professional skills to complete precise assembly after assembly.

The first step in installation is usually "chassis assembly." Workers first connect the track frame to the drive wheels and guide wheels, adjusting the track tension to ensure the tracks don't jam or loosen during rotation. This step requires multiple people working together; some are responsible for positioning, others for tightening bolts, and every action must be coordinated seamlessly. Next comes the installation of the main body, hoisting the cab, engine, and other core components onto the chassis and then securing them with bolts. During hoisting, the workers are fully focused, controlling the angle and force of the hoisting to prevent components from colliding with other structures.

The installation of the hydraulic system is both the most challenging and crucial part of the entire process. The hydraulic lines, like the "blood vessels" of a mini excavator, are responsible for transmitting power. Improper installation can range from affecting equipment performance to causing hydraulic oil leaks and potentially leading to safety accidents. The workers meticulously connect each hydraulic pipe precisely according to the blueprints, securing them firmly with pipe clamps and sealing the joints to prevent leaks. After installation, they test the hydraulic system, checking the flexibility and coordination of each movement to ensure the excavator's digging, rotating, and lifting functions operate normally.

Finally, the electrical system is installed and tested. The workers connect the wires according to the circuit diagrams, install the instrument panel, control handles, and other control components, and then test the operation of the electrical equipment, such as whether the lights are working properly, whether the instrument panel display is accurate, and whether the control handles are responsive. Only when all systems are tested and approved is a mini excavator truly considered installed and ready for operation.
