Application of Cluster Drilling Hammer:
A cluster drilling hammer runs several DTH hammers side by side on one drilling head, cutting ultra-large-diameter holes far faster than a single hammer could manage — used on hard-rock foundation work, wind-turbine foundations, large-scale micropiles, and limestone mining.
Features of Cluster Drilling Hammer
– Parallel hammer operation delivers 3–5× the drilling speed of a single hammer.
– Symmetrical bit arrangement keeps holes round and on-line.
– Modular build lets individual hammers be swapped without pulling the whole head.
– Vertical impact transmission limits vibration to surrounding structures.
– Covers working diameters from 160mm to 1010mm.
