horizontal directional drilling machine HT-120L

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. This machine is also used to pave the big long distance pipe. Characteristics >>The feed mechanism drives the gear-rack transmission.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.Pushing structure is chained wheel mode to reduce bearing capacity of roller chain, increase drill rigs pullback force storage, enhance safety factor, which can save 20kw engine power.Comfortable driving cab and concentrated control tower make operation more conveniently.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.The carriage with rollers reduces the friction and improves the lifetime of extension guide.Exclusive slide drill frame provides a range of setup angles for varying jobsites requirement.3.2t hydraulic crane makes assemble and disassemble drill rods and drill tools more conveniently and flexibly and improves work efficiently.Rotary power head is driven by three Hydraulic motors with stable movement and high rotary torque. Meantime, they match with pullback force reasonably.The power station uses Cummins engine of America. And it is robust and reliable.It equipped with 100hours high energy cell in order to complete long distance drilling. Specification >>SpecificationsUnit120 LEngine PowerKw235+265Max.
