Used Water Well Drilling Machine For Sale(hfw300l)
Brief Introduction
1.HFW300L is a kind of light and high efficient multi-functional water well drill rig with steel track, it is widely used in engineering construction for drilling wells, monitoring wells and ground-source heat pump air-conditioner, and also applied in hole blasting, bolting and anchor cable, ect.
2.Unique top rotary power head and hydraulic pushing mast. Adopt cone bit drilling, direct and reverse circulation covering, sand gravel layer, sand layer, bedrock.
3.Machine drilling frame lifting, drill rod assemble and disassemble, supporting leg leveling, winch, walking and other system shall all achieved by hydraulic system, and improving the working efficiency and saving labor force.
Techinical Characters
Guide lane matches with roller skate, it can reduce the sliding resistance,and also reduce friction and improve the lifetime of extension guide.Power head adopts separating mechanism, make drill pipe downhole operation easy.Two-speed hydraulic regulations is used in rotary,trust,lifting,shall make drilling specification more match with well working situation.
Hydraulic system equipped with separate air-cooled hydraulic oil cooler, and can optional install water cooler to ensue hydraulic system keep continuous and efficient operation under the high-temperature weather conditions of different regions.Lifting hoist can flexibly hoist drilling tools or assistant tools within it.
Four hydraulic jack can quickly level drill frame to ensure drilling accuracy.
Combination of drill rod lifter and hydraulic wrench make drill rod installed and disassembled safe,convenient,fast and save labor force intensity so as to improve working efficiency.
5.Four strengthened hydraulic jacks can become self-loading system, to ensure rotation easy and save lifting costs.
6. With 10-15 tons of truck provide by customer,the machine can be converted into a type of truck carriage water well drill rig HF300C.
