The working device’s boom, arm, and bucket are driven by hydraulic cylinders for flexible movement. The bulldozing device is used for site leveling, with connecting rods and pins ensuring tight component connections.
In the upper part, the engine and main pump are the core power sources. The engine shock absorber reduces vibration, and the main valve controls the flow of hydraulic oil. The slewing frame supports the upper structure; the seat and canopy enhance operating comfort; and components like the slewing bearing enable smooth rotation.
In the lower part, the traveling frame supports the entire machine. Like the rubber tracks commonly used in hydraulic crawler excavators, they have low ground pressure and are suitable for various terrains. The guide wheel, support wheel, drive wheel, and tensioning device work together to ensure smooth travel.
(3)Working Principle
Mini digger machine operates based on hydraulic transmission. After the engine starts, it drives the main pump to convert mechanical energy into hydraulic energy. High-pressure hydraulic oil is delivered to each hydraulic cylinder through pipelines.
For digging, oil enters the boom cylinder to extend or retract it, lifting or lowering the boom. Similarly, the arm cylinder and bucket cylinder work together to complete digging and loading operations. The slewing motor drives the upper part to rotate 360°, and the travel motor drives the tracks, allowing the equipment to move flexibly to the working position.
On a farm in Australia, manual digging of irrigation ditches was inefficient and struggled to maintain uniform specifications. After introducing mini digger excavator, one operator could finish the work in one day that previously required five people for three days. The ditches had uniform depth and width, greatly improving irrigation efficiency and providing better water conditions for crops.
During a pipeline renovation in an old community in India, large equipment could not enter due to narrow roads. The construction team used hydraulic crawler excavator, which, with its compact and flexible body, moved freely between buildings and dug trenches for pipeline laying accurately. The construction caused no significant damage to surrounding buildings or greenery, completing the project on time and winning praise from local residents.
In a school playground renovation project in the United States, removing the old runway was challenging: manual work was slow, and large demolition equipment risked damaging surrounding facilities. The constructor used mini track excavator with a crushing attachment to break the old runway quickly. Its built-in leveling function also prepared the site efficiently, laying a good foundation for the new runway and significantly shortening the renovation period, saving time costs.
