Standard Weekly Maintenance for Hydraulic Breakers: Cut Failure Rate & Extend Service Life
To help customers lower maintenance costs and maintain stable construction efficiency, this popular science article covers standard weekly maintenance procedures for hydraulic breakers. Hydraulic breakers operate under constant high vibration and heavy dust exposure. Most common malfunctions including oil leakage, weak impact force and broken bolts are caused by insufficient periodic inspections.
Four core inspections shall be carried out after weekly shutdown: First, test the nitrogen accumulator pressure and fill pure nitrogen as required by model specifications. Abnormal pressure will directly weaken impact power and accelerate wear of internal components. Second, fully tighten all side plate and cylinder fixing bolts. High-frequency vibration tends to loosen bolts, which may lead to severe cylinder scratching. Third, check the wear condition of chisels and inner/outer bushings, and apply special grease to block sand and debris from entering the cylinder chamber. Fourth, inspect all hydraulic pipes and sealing joints for leakage, and clean dust on pipelines to prevent impurities from scratching pistons and valve assemblies.
All hydraulic breakers under Ramtec undergo rigorous heat treatment and structural optimization. Combined with standardized weekly maintenance, their service life can be greatly prolonged. Proper maintenance ensures consistent powerful performance, reduces downtime losses, and delivers higher returns for mining, municipal engineering, demolition and other working conditions. We will keep releasing equipment maintenance guides to provide full-cycle supporting services for global partners.
