Energy-saving and efficient DTH hammer
Urban high-rise building construction, high-speed rail, highways, bridges, subway construction, hydroelectric stations, nuclear
power plant construction projects will involve the pile foundation project. With the increasing demand for hard rock drilling in these
projects, the new New Diamond designed Super series hammer and bits speciﬁcally for these types of projects is being developed
by most experienced engineering experience in large diameter boreholes and ultra-deep boreholes drilling, fully meet the requirements
of the pile foundation construction drilling work.
It has following advantages:
01 Bit without foot valve will avoid the problem of foot valve broken or thermal expansion
02 Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.
03 Less parts, simpliﬁed, and with parts proper heating treated.
04 Extend the life of using and easier to repairing.
