BK pneumatic hammers concrete and efficient hydraulic hammers hydraulic hammers coal industry standard models focus on the direction of change and turnaround pneumatic hammers further contraction in domestic consumption of coal, coal from the severe impact of future price movements in both directions. To this end, in 2020, Shanxi Province, in principle, to the new configuration of the portable hydraulic hammers coal resource; except off small on large reduction replacement, but no longer approve the construction of new coal projects; strict control of coal production capacity; to stop the approval annual output of 500 million tons for underground mining projects open to change; actively balance between supply and demand of coal resources, major issues of strategic reserves, hydraulic hammers futures model specifications, price formation mechanism, continue to promote coal management system to achieve new breakthroughs. Hydraulic hammers Overview: for crushing concrete and asphalt compaction ﹑ ﹑ piling work, is widely used in road maintenance ﹑ rescue and other water and gas. Product Features: maximum power to weight ratio; damping handle, the operator can reduce recoil; low noise, suitable for urban road construction work and road network; and can match a variety of drill rod to fit different crushing materials.
