Features:

• 1. HW-420B 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 HW-420B 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 HW-420B 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.
