The CTR450 boom-type roadheader is 21 meters long, 4.1 meters wide and 5.1 meters high, with a cutting power of 450/350 kilowatts, a single positioning cutting range of 9.3*8.2 meters, a de-dusting air volume of 1,500 cubic meters per minute and a total weight of 188 tons. The product is uniquely designed with a telescopic cutting arm with a maximum elongation of 1.2 meters, enlarging the cutting area by 20%. The design team of China Railway Engineering Equipment Group Co., Ltd. (CREG) has conducted a series of targeted designs to improve the cutting efficiency and lower the consumption rate of cutting picks, and has solved the technical problem of the contradiction between low temperature start-up and high temperature heat dissipation of the equipment. The technical team also developed the cab with patented technology, which greatly improves the construction safety. CTR450 is a 'powerful weapon' for tunnel construction, and is applicable to single-track, double-track, double-arch tunnels (channels) and underground tunnels of different sizes and types, in railways, highways, subways, water conservancy projects, municipal projects and mines.
