Product features:

①Multi-column support, good overall frame stability, stable and reliable working resistance;

②The front end of the device is equipped with front and rear combined cantilever beams, and the access mode can be selected according to different working conditions;

③The beam adopts an integral articulated connection, which is convenient for installation and disassembly and has good connection with the top;

④This device can be used in conjunction with a tunnel boring machine, an anchor drilling vehicle, a two-wheeled vehicle, and a self-moving machine tail to achieve rapid tunnel excavation operations and greatly improve tunnel excavation efficiency;

⑤The top beam is welded with high-strength steel plates to meet the support strength while reducing the thickness of the top beam, increasing the working space under the machine body, and making the drilling rig construction more flexible during support;

⑥Each action of the device is controlled by a hydraulic system, the system performance is stable and reliable, and the unit failure is low;

⑦The front and rear frames of the device are pushed and pulled by hydraulic cylinders to achieve step-by-step movement, with a large step-by-step movement distance, and safe and reliable frame movement
