Product Name:HH Series DTH Hammer
Products Features:
HHSeries DTH hammers are widely used in ground project for diving all kinds of mid-hardness,high-hardness and somehow worse drillability rocks,characteristics are as follows:
1HH low pressure DTH hammers belong to air exhaust centre- valve hammers,which have a good effect in exhaust rock power,reduce re-breaks of rocks’power,and lessen the damage of drill to advance drilling efficiency.
2Under the most-advanced drilling theory using in inside measurement design,hammers have more expected energy transmission,and let hammers have more power every single time,more speeder in drilling,less wind exhaust.
3Choosing the most high-quality raw material and most advanced technique,hammers have a more stable ability and longer servicing life.
4,More easilier in disassembly and assembly,lower trouble,more convinient in repairment.
Products Scope:
boosting holes in mine,roads projects,drilling holes in protacting landslides and dams and so on.
