A wheel excavator is a versatile construction machine equipped with a large, toothed bucket at the end of a hydraulic arm, mounted on wheels for enhanced mobility across different types of terrain. Its design allows for efficient digging, lifting, and loading operations, making it ideal for tasks such as trenching, landscaping, and road construction.

A backhoe loader, often referred to simply as a "backhoe," is a multipurpose construction machine combining the capabilities of a front-end loader and a rear-mounted excavator arm (backhoe). With its front loader bucket for scooping and lifting tasks and the rear backhoe for digging and trenching operations, it's widely used in construction, landscaping, and agricultural projects for its versatility and efficiency.

A mini excavator is a small mechanical device whose main purpose is for light earthmoving and mineral mining. Due to its small size, convenient and flexible operation, and low cost, it is widely used in urban construction, infrastructure construction, farmland construction and other fields.
