The ROCKA Box Muted Hydraulic Breaker is highly favored among hydraulic breakers due to its low noise level, energy efficiency, and environmental protection features.
Application:
1.Extraction and excavation of minerals, mining operations, crushing and screening of ores.
2.Processing of steel in metallurgical plants, removal of slag, dismantling of equipment foundations.
3.Repairing highways, breaking cement pavements, excavating foundations.
4.Constructing iron roads on mountains, driving through tunnels, demolishing road bridges, compacting roadbeds. Demolition of old buildings, breaking reinforced concrete structures.
Grease moving parts weekly to prevent corrosion.
Inspect hydraulic hoses for leaks or cracks.
Store indoors when not in use to avoid weather damage.
Replace worn striking caps to maintain driving efficiency.
