Built for Deep & Difficult Jobs

The JH9215 provides the reach, digging depth and flexibility required for specialized excavation projects. Its telescopic boom allows operators to work deep below ground level while keeping the base machine safely positioned on the working platform.

Compared with conventional long-reach excavators, the telescopic arm excavator design provides greater digging depth, improved vertical stability, and higher productivity, making it an ideal solution for diaphragm wall construction, deep foundation pits, subway projects, underground utility installation, and shaft excavation.

Engineered for urban construction environments, the machine features a compact structure, low operating noise, and excellent operator visibility, allowing safe and efficient performance in crowded city job sites, tunneling projects, and restricted working spaces.

With powerful digging force, precise control, and reliable performance, the telescopic clamshell excavator ensures safe, stable, and highly efficient deep excavation operations, even in the most demanding geotechnical and underground engineering conditions.
