New technologies and new features 1. It is equipped with forehead cylinder, through which the pulley-yoke can automatically fold the mast, so as to reduce labor intensity and improve work efficiency; 2. This drill rig uses the most advanced electronic leveling device which can switch between manual operation and automatic operation and is capable of real-time monitoring the mast and carrying out automatic adjustment to ensure the mast is always in the vertical state during construction operation, and this can effectively ensure the pile-hole verticality meets the requirement of the engineering. 3. Hydraulic system uses advanced negative flow control technology, realizing the flow distribution as needed. In addition, the superposition of electric power can avoid overload, so as to maximize the use of engine power; the hydraulic system, with pilot proportional control valve, is high efficient and energy-saving and has high control accuracy. The drill rig can automatically adjust power head's torque and speed proportion according to the hard and soft degree of the stratum. This not only can ensure the high-efficient drilling and make sure the engine run stably, but also can reduce the requirements for operator's skill. 4. The electrical system adopts electro-hydraulic proportional control technology and CAN bus distributed control technology. This drill rig uses the most advanced electronic leveling device which can switch between manual operation and automatic operation, realizing high-precision detection of mast angle (accuracy ¡Ü0.1 degrees) and depth detection precision of ¡À0.5m (excluding cumulative error), as well as rotation detection accuracy of ¡À 0.05 (excluding mechanical error), so as to fully guarantee the quality of construction.
