HW920/920-1Separated DTH Surface Drill Rig


  • This model is equipped with a dual-motor rotary head and a multi-way valve with adjustable rotary speed. The rotary torque can reach 2200N.m, which meets the needs of 76 drill pipes and 130 bores. The rotation speed can reach up to 150 revolutions, which meets the needs of some customers for high-speed drilling in soft rock formations. At the same time, the 920 series models are equipped with engineering tracks and plunger motors as standard, which increase the leveling function, improve the climbing and cross-country performance of the equipment, and can adapt to complex terrain conditions. Vertical holes can be drilled for slopes to meet the needs of different working conditions.

  • Features:


    • 1. HW920 model uses double cycloid motor slewing head, with large torque and fast speed, which can meet the requirements of 76mm drill pipe and 130 hole diameter.

    • 2. The HW920 series is equipped with engineering crawlers and plunger motors as standard, which makes the product quality more reliable, stronger driving force, and can better adapt to the complex geological and road environment of open-pit mines.

    • 3. The centralized control console is easy to operate, improve work efficiency, and increase the safety and comfort of operation.

    • 4. The HW920 series drilling rig has added leveling function, which improves the climbing and cross-country performance of the equipment, can adapt to complex terrain conditions, and can drill vertical holes for slopes to meet the needs of different working conditions.
