- A new generation of dedicated chassis, equipped with parallel multi-pump system and a dedicated main valv, 299kW engine power meeting Euro III emissions standard.
- High-efficiency energy-saving system: The power system is more efficient and the higher transmission efficiency; the hydraulic system has less losses and maximized output power.
- Professional control system to ensure high efficiency and energy saving.
- Optimized design of the large triangle booming system, with higher support position, small mast deformation, and high hole formation accuracy; the use of rear support can ensure the stability of the machine under high crowd force, effectively ensuring the verticality of the hole formation .
- The main winch adopts a variable displacement motor, and the maximum single rope tension force can reach 450kN to ensure the lifting capacity; the drum adopts a single-layer long drum, which effectively extends the service life of the wire rope.
- Exclusive dual-reducer motor slewing lock mechanism, which is equipped with a lock device for the upper chassis and undercarriage cylinders for complicated working conditions, which is more stable and reliable during drilling..
- Portable counterweights can be installed on both sides of the chassis, which can increase the whole unit weight by up to 16t. While increasing the stability, it also increases the maximum machine crowd force t, which greatly improves the rock-drilling ability of the equipment.
- The torque of the rotary head is 390KN • m, with dual spring ,used to simplify the structure of the rotary head buffer device.
- Realizing various foundation construction with additional tools such as hydraulic hammer, CFA, guide type diaphragm wall grab, trench cutter, etc.
