HFW-300L 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,etc.
The rig is a unique patented products：Top drive rotary power head and a hydraulic rotary disk rotating mechanism, hydraulic motors, hydraulic winch chain propulsion for deep hole drilling in institutions and mast. The driller adopts the rotary drilling technology of reverse circulation drilling technology, mud, compressed air DTH hammer drilling technology, can finish cover layer, sand gravel, sand, rock layer stratum, large diameter deep hole construction. The drill, drill pipe rack lift unloading, leveling supporting legs, lifting, walking and other auxiliary movement by the hydraulic system, not only can improve the working efficiency, and reduces the labor intensity of operators.
* Guide lane matches with roller skate, it can reduce the sliding resistance,and also reduce friction and improve the lifetime of extension guide.
* Hydraulic power head and a hydraulic rotary disc motor chain, drilling and hydraulic winch binding, new drilling method, reasonable power matching.
* Set covering layer, stratum two kinds of method in one construction drill
* Travelling to tracked self-propelled structure, optional 6x4 heavy truck to car type well drilling.
* The rig is very convenient with air compressor and DTH hammer, using compressed air DTH hammer drilling technology, complete the bedrock drilling operation.
* The rig is equipped with patent technology hydraulic rotary disk, mud pump, hydraulic winch, the mud can be completed normal circulation drilling technology.
* Drill carriage slipway and roller skate matching，Namely, reduce sliding resistance, and reduce the slide wear. To extend the service life
* Two-speed hydraulic regulation 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 ensure hydraulic system keep continuous and efficient operation under the high-temperature weather conditions of different regions.
* Four strenthened hydraulic jacks can become selfloading system, to ensure rotation easy and save lifting costs.
