Product Description

HT-120L directional drilling rig adopts steel track .The machine is mounted on a diesel engine, a hydraulic crane, a truck-Mounted extension guide, a mud mixing pump, and a rotary head. It is convenient to move in urban areas. Hydraulic system adopts shut circuit for high efficiency and minimal operating force

Product Feature

> The feed mechanism drives the gear-rack transmission.rn> The pushing and rotation adopt the shut circuit system, the two plunger motors with the planet box to provide high efficiency and minimal operating force.rn> Pushing structure is chained wheel mode to reduce bearing capacity of roller chain, increase drill rigu2019s pullback force storage, enhance safety factor, which can save 20kw engine power. rn> Comfortable driving cab and concentrated control tower make operation more conveniently.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 reduces the friction and improves the lifetime of extension guide.rn> Exclusive slide drill frame provides a range of setup angles for varying jobsites requirement.rn> 3.2t hydraulic crane makes assemble and disassemble drill rods and drill tools more conveniently and flexibly and improves work efficiently.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> The power station uses Cummins engine of America. And it is robust and reliable. rn> It equipped with 100hours high energy cell in order to complete long distance drilling.rn
