overview

It is widely used in the construction of large and medium-sized tunnels and the reinforcement of small pipes, advanced supports and other projects. Its well-designed shape, configuration, system control and other aspects will provide customers with more high-quality anchor construction and reinforcement experience.

Innovative design, one positioning can meet the needs of multiple construction techniques, that is, drilling, anchoring, injecting, and drilling, injecting, and anchoring fully automatic integrated construction, highly mechanized, low labor intensity, and less manpower requirements.

Grouting and mixing integrated body layout design, efficient construction and flexible transfer. The information monitoring and reading system can monitor, download and store the data of the construction slurry water-cement ratio and single-hole grouting volume.

The design of one arm and one platform enables this bolting rig to have more functions. In addition to the integrated construction of drilling, anchoring and grouting on the main working arm, the service platform can be used for measurement, supplementary bolts, auxiliary installation of bolts, grouting, prying, etc. , One machine with multiple uses.
