BZC300CHW is truck mounted 300m water well drilling machine. It can drill in different layer(Clay layer, sandy soil layer, weathered rock, bedrock etc) with suitable drilling tools.With reasonable design, superior performance and complete tools, it can drill with different technology, eg. mud, air foam drilling, DTH drilling, air- lifting reverse drilling to suitable different stratum.
The rig has auxiliary rod relief cylinder which push the ratchet teeth reverse rotation to dismantle the first joint thread of drill pipe, then rotarytable reverse rotate,so lighten labor intensity and improve the life of spare parts.

Rotary table is the main part of drilling machine.Gear and bearing lubrication way is splash lubrication. When drilling, must put lubricating oil.Open the bolt on the rotarytable neck and open the oil spilling hole plug of the body, add the oil from the neck until the oil outflows from the spilling hole.Summer use85W/90GL-5 gear oil, winter use 85W/90GL-4 gear oil .
