200 Meter Rock Well Drilling Borehole Crawler Mounted Drilling Rig
Product Advantage:
1.Drilling rig uses automatic telescopic drilling rig(Julong patent),it uses two high-strength cylinders to support.There is a group of hydraulic valves to control supination of drill tower so that it saves time and effort, safe and reliable when user operates, the maximum for the user to create benefits.
2.The chassis uses a rubber belt track so that the weight is light,the cost of life cycle is lower.It can reduce noise of the vehicle walking mechanism,reduce car body's shake,redue the oil consumption.It can walk on the pavement of city and don't hurt the pavement.
3.The chassis comes with four high-strength threaded legs(or Hydraulic high leg) the threaded legs installate and adjust is fast and convenient, can be used for work plane leveling.It can make loading and unloading reduce the cost of to improve efficiency.It also can be used as auxiliary support when the track drilling rig is working.
4.Using 48V electric starting diesel engine is reduced the operate's labour intensity greatly.Especially in cold season,when diesel engine start hardly,it will show superiority vastly.
5.The machine is equipped with BW-160 independent mud pump,the pump flow and pressuer are big,the maintenance is convenient,the parts of the machine are convenient to buy all over the country.
6.There are several kinds of models,for example ST-300/ST-200/ST-180/ST-150/ST-100.

Matters Needing Attention in Drilling Process Of Crawler Drilling Rig
1. After drilling structure of crawler drill bit, the center drilling tool needs to be replaced in time. Firstly, the hole bottom needs to be cleaned, and then the residue at the bottom of the hole is blown clean. After the bit stops rotating, the drilling tool in the drilling rig is slowly lifted up. When the lifting force is good enough to lift the drilling tool, it is appropriate.
2. When the drill bit of crawler drilling rig is summarized in the drilling process, it is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and timely keep the hole clean when necessary, and the drill bit in the drilling rig is not allowed to pull out forcefully during the drilling process.
3. Sometimes more residual rock slag will be left at the bottom of the hole of crawler drilling rig, and the rotary part of the eccentric bit will be blocked by the rock slag, which will affect its closing production. At this time, it is necessary to transport compressed air, clean the hole again, and make the DTH hammer work for a short time, and then lift the central drilling tool again.
