TAR12A Anchor Drill Rig

　　The prowess of TAR12A anchor drill rig and TR550D rotary drilling rig highlights technological responsibility
　　TAR12A anchor drill rig, a high-quality equipment with super power for drilling through mountains and holes in construction. Anchor drill rigs are the main equipment for anchor support engineering, mainly used for landslide anchoring, culvert and tunnel hole wall support, deep foundation pit support, etc. Beijing CSR Times Locomotive and Rolling Stock Machinery Co., Ltd. has independently developed and launched the TAR12A anchor drill rig, which is mainly suitable for grouting operations such as slope anchoring in engineering construction, sheet pile anchoring in foundation pit support, tie rod anchoring in railway fill foundation, pipe roof construction, drilling and grouting of foundation, water stop and rock reinforcement in tunnel construction, detection and discharge of water inflow and gas in tunnel construction, exploration drilling and core sampling, water finding and water well drilling, etc.
　　The TAR12A anchor drill rig independently developed by CSR Beijing Times has super power for drilling through mountains and holes in construction, mainly because the product's engine, power head, and main hydraulic components all use original imported parts, ensuring product reliability. The luffing and slewing mechanism is controlled by multiple oil cylinders, enhancing the flexibility of the drill rig and enabling multi-directional rotation or tilting of the drilling system, thus ensuring the drill rig can work under various working conditions and greatly enhancing its adaptability to the construction environment. A set of adaptive oil cylinders is installed on the drill rig chassis, which can adjust the angle of the upper platform relative to the lower chassis, so that the drill rig can adjust its center of gravity to the optimal position through self-adjustment when working on uneven ground. Its outstanding performance and features are: first, convenient loading and unloading of drill pipes. During operation, the plane of the power head trolley guide rail can be adjusted to be perpendicular to the vertical plane or at a small angle, facilitating the loading and unloading of drill pipes. When unloading drill pipes, workers do not need to lift and connect drill pipes; the drill pipes fall freely and are then transported to the designated location, avoiding accidents of pinching or hitting workers during loading and unloading.
　　Second, forward rotation maintenance function. During normal operation, pressing the forward rotation maintenance button can conveniently keep the drill pipe rotating forward without the need to hold the operating handle for a long time, making operation easier. At the same time, it has excellent waterproof performance. The operating platform is designed to be waterproof, so no matter wind or rain, it will work as long as you do.
　　Third, it adopts the German Eurodrill HD5012 power head with a maximum impact energy of 650 N•m, ensuring adaptability to various strata. In addition, it uses a maintenance-free hydraulic drive chassis with low center of gravity and good stability, and has a pair of adaptive oil cylinders, allowing the whole machine to be adjusted within ±10° from the horizontal plane, ensuring the stability of the whole machine during operation.
　　Fourth, the chassis is equipped with two independently adjustable rear outrigger oil cylinders. By cooperating with the adaptive oil cylinders, the whole machine can conveniently adjust the levelness of the body in working environments with poor ground flatness. At the same time, the luffing and slewing mechanism is controlled by six hydraulic oil cylinders, which is easy to operate and maintain. The multi-directional and multi-angle adjustability ensures adaptability to complex working environments. Because the product uses imported Cummins engines, the whole machine has very strong power. 　　TR550D rotary drilling rig, the product that won the 2015 Construction Machinery TOP50 Application Contribution Gold Award. The "2015 Construction Machinery Product Development (Beijing) Forum and China Construction Machinery Annual Product TOP50 Award Ceremony" was held in Beijing on April 10 this year. The TR550D rotary drilling rig of CSR Beijing Times was the only rotary drilling rig product shortlisted and awarded the Gold Award. 　　At the award ceremony, Huang Zhiwen, General Manager of CSR Beijing Times, received the award and spoke.
