Driven by diesel engine;Suitable for scaling operations in tunnels and non coal mine hill andvarious underground projects.

Here is the English translation of the paragraph:

The folding working arm is equipped with a hydraulic hammer driven by a rotary cylinder and a mechanical parallel linkage, enabling full-scale operation on the working face, roof, side walls, and floor. The hydraulic system features proportional pilot control, offering flexible operation and smooth movement. With its compact structure, good mobility, small turning radius, and strong climbing ability, this equipment significantly improves the efficiency and safety of scaling operations.
