- The hydraulic longhole drilling rig is equipped with heavy-duty aluminum feed beam, which is supported by hydraulic cylinders to ensure the smooth drilling operation; The hydraulic guide cylinders are used to ensure that bores are drilled with near perfect straightness;
- Trolley-type control panel offers easy operation and gives operator good visibility, and remote control is optional to improves the operation safety;
- The articulated chassis adopts a hydraulic drive system, and 1.6m wide drilling rig is suitable for small to medium-sized tunnels;
- Stepped piston is used in rock drill (drifter), which helps increase drilling speed, improve the efficiency of impact energy transfer from drill to rock, and reduce the consumption of drilling tools while maintaining the condition of the drill rig;
- The hydraulic longhole drilling rig can realize economical drilling with drill depth of up to 35 meters, optional rod handling system (27 1 rods) allows for one-person operation;
