Good Performance High Speed ST 350 Meters Depth Crawler Mounted Drill Rig
Product Description
ST 350 Meters drill water well for farm /industry irrigating,
fresh water drinking or anywhere need fresh water. The drilling
depth for one time can reach 6.6 meters, which save the time to
load the drill pipes and also save the human resources;Adopting
double cylinder to lifting, lifting force can reach 24 tons;The
four strong legs can lift 1.7 meters, and the real ground clearance
can reach 1.45 meters, which easy to stable the machine and
convenient for the loading during the transportation;

Product Main Features
1, It has hydraulic automatic feed mechanism structure, improves
drilling efficiency, reduces labor intensity.
2, It adapts the ball chunk mechanism instead of the card holder
,it can implement non-stop down the lever, easy to operate, safe
and reliable.
3, Winch contains cage, forms a duplex structure supporting the
star wheel, it can withstand strong impact.
4, Four groups of vertical box bearing retainer to ensure that the
rotation has sufficient rigidity to deal with complicated
geological conditions gravel layer, gravel layer, etc.
Drilling Rig Working Attentions
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.
