Multi-function crawler DTH drilling rig for selling!HFDZ350 high cost performance DTH drilling rig

Main applications:

  HFDZ350 Multipurpose drilling rig is a simple effective and multi-function crawler-type driller. Mainly applying to drilling of wells monitoring wells, air-conditioner hole of ground coupled heat pump and other drilling holes. Especially to project with effective and close air-conditioner hole of ground coupled heat pump. It is also applied to drilling work in hydroelectric power, Metallurgy , highway ,construction materials, railways and national defense, etc. It is suitable for rock drilling, especially for medium hard and hard rocks, as well as for blasthole drilling and anchor wire hole in prestress, etc. IT is self-moving multipurpose drilling rig, driven by diesel engine, which is easy for removing.

This drill rig can be applied to down-hole drilling for various ground levels with compressed air. The uplifting and lowering for drilling tower, up and down for drilling materials, installation and dismantling of drilling pipes, gyration and feeding up, ground jack, hoisting and moving, etc are all realized by the hydraulic system. This has greatly decreased the labor intensity, and has improved the construction efficiency and project quality.

Main characteristics:

(1)     This drill rig adopts all-hydraulic transmission, which helps realize the integration of machine, electricity and liquid. The transmission is stable with less noise and concentrated operation, and it is convenient, easy, safe and reliable, as well as low failure rate and high cost performance.

(2)     The power unit of drill rig is driven by lower-speed with a big torque. Broad rotating range can be applied to various drilling technique and rotating speed and torque requirement for different drilling holes diameters.

(3)     Drilling rig is arranged with orifice set, drif diameters is large, and use easily, which could realize automatically screw off.

(4)     Drilling rig takes the drilling mode of motor driving chain, pluse-pressure is equal to reducing pressure and feed pressure. Feeding course is long and it could add three meters adrill stem which reduces service working rime effectively.

(5)     Drill rig is equipped with bit pressure meter and hydraulic system pressure gauge, which observe service behavior and in-hole state timely.

(6)     Drill rig is driven by diesel engine and is equipped with hydraulic steel pedrail, which could make self-moving with strong crossing performance.
