BK hydraulic hammers hydraulic hammers handheld portable hydraulic impact hammers BK hydraulic power station hydraulic breaker hammers Hammers supporting ongoing management and troubleshooting, BK hydraulic hammers "fighting rule violation" special action, so that the investigation does not stay dead, remediation leaving troubles; deepen key areas, mining supervision of law enforcement to crack down not approved the first building, unlicensed production, hand-held hydraulic hammers "three ultra" and other illegal violations. Solid job hidden causal factors control work to strengthen "one through three defenses" management, strict gas prevention and control capability assessment, grade identification and other sectors, so that a reasonable system, hydraulic impact hammers good facilities, adequate air flow, air flow stability and ensure safety. strengthen the "three staff positions," and full of training and education, strict implementation of the separation of teaching and testing system, effectively grasp the culture of safety experts. 1, hydraulic ho is to provide hydraulic power from the gasoline engine or electric hydraulic power station, drive within ho body piston blow-ho brazing operations, internal combustion hammers through ho who own a small two or four-stroke gasoline engine directly drives the piston blow-ho brazing operations. 2, hydraulic ho needs with a hydraulic power station, a set of hydraulic pipes, picks one; the internal combustion engine with a pickaxe picks one, alone, more convenient mobile transitions. 3, closed or poorly ventilated spaces for hydraulic ho use. 4, hydraulic ho underwater construction type. 5, hydraulic pickaxe self-lubricating, longer life, hydraulic transmission, power output more stable 6, hydraulic pickaxe can not use the tilt angle limit. 7, hydraulic ho expensive, lower combustion ho prices.
