Boring and pile-driving machine BM-831

Minor-drilling machine BM-831

Minor-drilling machine BM-831 is designed for drilling in the soil for up to IV category SNiP IV-2-82, including forever frozen, as well as highly saturated moisture, and the availability of plyvunov and lenses, installation and clogging of reinforced concrete and metal piles in the construction of piled Foundations of buildings and structures, power lines, etc. Maintenance of machines permitted in temperate zones in the range of ambient air temperatures from minus 40 ° C to 40 ° C plus.
