Profile: China flying technology Limited provides tools & equipments for construction, quarrying & concrete demolition, cutting, drilling & bursting. Our products include hydraulic rock & concrete splitter, rock drill, splitting machine, rock jack, rebar cutter, crusher & concrete burster, diamond blades, stone crack expander, diamond core bits and down hole drill. Our QL-Y48 hydraulic rock drill is a hi-tech product driven by high-pressure hydraulic oil. It adopts advanced technologies and innovative structure, featuring low energy consumption, small size, light weight, huge impact energy, fast drilling, low noise, litter vibration & trivial labor intensity. It is widely applied to drill mines of marble, electric, granite, metal, non-metal and coal mines. Hydraulic concrete crusher employs the use of hydraulic jaws/pincers to crunch reinforced concrete/masonry into suitable-sized pieces for disposal. It is useful in locations such as walls and slabs that are difficult for robotic machines to access. These hydraulic concrete crushers have advantages that include silence operation, dust-free, vibration-free, easy handling and can be operated without water. Our hydraulic core drill produces a smooth positionally-accurate hole through reinforced concrete, brickwork and stone, with no dust in operation, high efficiency, smooth coring, and accurate sizing. These are applied in the areas of construction installation, earthwork quality inspection, installation of water, electrical, heating, and gas supply systems, reinforcement of railway, bridge & tunnels installation.
