Recently, the newly developed miniaturized ZYS123AG-FL full computer three-arm rock drillingtrolley of Railway Construction Heavy lndustry is suitable for the construction of a tunnel of Plateaurailway. The driling trolley is responsible for the excavation of the face of the hand, auxiliary charge.pipe shed, and anchor procedures. The average drilling speed of the trolley is 3.5 meters/min, theequipment failure rate is low, the excavation footage of each shift is more than 3.2 meters, and thedrilling operation time is about 2.5 hours.

The ZYS123AG-FL all-computer three-arm driling rig can solve the problem that the existingconventional three-arm driling rig in the market is difficult to enter and exit the tunnel due to itsrelatively large size. The length of the machine is 15.7 meters, the width is 2.65 meters, and thewingspan boom structure is adopted. The maximum working height is 12.6 meters, the maximumworking width is 15.8 meters, and the maximum driling depth of a single pole is 4.6 meters. Thetruck is equipped with a full computer control system, with efficient and accurate driling, anti-sticking dril, fault diagnosis, construction log recording and storage functions; At the same time.according to customer demand, the function has been expanded and upgraded, so that the threearm driling rig has the functions of anchor rod construction and exploration hole construction.

China Railway Construction Heavy Industry will continue to adhere to customer demand as theguide, carry out independent innovation, vigorously develop information and inteligent constructioneauipment, and contribute to the intelligent construction of tunnels in China.
