DTH hammers use a low air pressure range of around 12 to 18 bar, which is significantly lower than the pressure used by conventional high-pressure DTH hammers. This means that they produce less noise and vibration and cause less ground disturbance during drilling.
DTH Hammers: Jinxin's DTH hammers are all simple structure, easy to assemble and disassemble, as well as reliable quality and long service life. Zhuzhou Jinxin has various hammer models suitable to drill holes from 64mm to 1000 mm (2-1/2” ~ 39-3/8”) in diameter; and come with three kind: low pressure (5 ~ 7 bars), middle pressure (7 ~ 15 bar) and high pressure (7~ 30 bars).
DTH hammers mainly be produced with shank type of DHD, QL, SF, COP, Mission, SD, BR, CIR and ACD series, Diameter ranging from 2” to 8” for mining and quarrying, and 6” to 32” for water-well drilling, oil-well drilling, foundation and so on.
