Product Description

HT-20L directional drilling rig adopts full hydraulic and high intensity rubber track. The machine is mounted on a diesel engine, a truck-Mounted extension guide, a mud mixing pump, and a rotary head.

Product Feature

> Two-speed gear is used in rotary and thrust system which is in favor of hole clearance and pullback process, and to improve working efficiency and success rates. rn> Heavy-duty Hydraulic rotary power head adopts rock drill head. It can bear a larger impact load and it is more suitable for dry or wet drilling and improves lifetime in dry or wet drilling.rn> The carriage with rollers can reduce the friction and improve the lifetime of extension guide.rn> Rotary power head is driven by three Hydraulic motors with stable movement and high rotary torque. Meantime, they match with pullback force reasonably.rn> Feeding carriage has a clearance to protect the drill rod's threads and prolongs the life.rn> Hydraulic auger anchor device saves labor force and increase efficiencyrn> Two hydraulic clamps make assemble and disassemble drill rods more conveniently and effectively.rn> Optional available stress device makes pullback force come up to 32t, which used in dealing with drilling rod freezing.rn> The power station uses Cummins engine of America. And it is robust and reliable.rn> The main hydraulic parts (e.g. hydraulic pump, hydraulic valve, hydraulic motor, etc.) adopt imported products or famous domestic companies.rn
