Product Description
JL-420B/420B-1 is equipped with dual motor rotary head and slewing speed adjustable multi-way valve, with a slewing torque of up to 2200N.m, meeting the needs of 76 diameter drill pipe and 130 hole diameter. The rotation speed can reach up to 150 revolutions, which meets the needs of some customers for high-speed drilling of soft rock formations. At the same time, the 420 series models are equipped with engineering tracks and plunger motors as standard, which increases the leveling function, improves the climbing and off-road nature of the equipment, can adapt to complex terrain conditions, and can punch vertical holes for slopes to meet the needs of different working conditions.
