Jack Hammers (<=5m) serve as critical tools in construction demolition and tunnel support due to their portability and high-frequency impact technology (2000-3000bpm). Key advantages include: ① lightweight design (<=30kg) enabling single-operator use in confined spaces; ② optimized drill bit diameters increasing rock-breaking efficiency by 25%; ③ intelligent vibration damping systems extending daily operation to 8 hours. In metro station projects, integration with hydraulic booms achieves 0.8m/min drilling speed - 4x faster than pneumatic picks.
