Adopt 6th generation Kelly bar, integrated locking device, upgraded material, reinforced ring, increase strength by 25%, achieve strong impact resistance, increase crowd force by 15% and rock drilling capacity by 25%; for 5-section interlocking bar, the hard rock drilling depth can be up to 88 meters. Economy and energy saving: By collecting big data, the average comprehensive fuel consumption is lower than that of similar models in the industry. Adopt parallelogram structure, more flexible and free of site limitation. The whole machine design standard is high, the design life of structural parts > 20,000 hours. 1) HD touch screen, 3ms refresh frequency, no visual delay. 2) The display function of the locking device can accurately display and guide the locking and unlocking of the Kelly bar locking device, which reduces the wear and eliminates the accident. SANY owns the patent of this technology. 3) Roller bit auto drilling function: Set the speed of rotary drive to realize automatic drilling. 4) Wire rope pre-tensioning technology: The pre-tensioning force is always applied on the main rope to avoid random rope and twisting. Automatic centralized lubrication and combined counterweight, reduce dismantling time and improves transfer efficiency.
