Maintenance of crane wheels: How often should maintenance be performed, and what does it entail?
· Daily pre-shift inspection (operator): Visual inspection + no-load test run
· Weekly inspection: Basic inspection, cleaning, and grease replenishment
· Monthly maintenance (Level 1): Tightening, lubrication, and clearance checks
· Every six months: In-depth measurement, wear inspection, and bearing condition assessment
· Annual comprehensive maintenance (annual inspection): Disassembly inspection, non-destructive testing, geometric accuracy correction, and coordination with the annual inspection of special equipment
What materials are used for crane travel wheels?
65Mn, high-carbon manganese steel, with a hardened tread (HRC 45–52); offers good wear resistance and high cost-effectiveness; corresponds to European Standard C67; 42CrMo, an alloy quenched and tempered steel, offers superior toughness, contact fatigue resistance, and impact resistance compared to 65Mn; 45# steel, the lowest-cost option with average wear resistance, is commonly used for the running wheels of small hoists and simple overhead cranes that are not used frequently; the tread is hardened. Equivalent to European Standard C45.
What types of bearing steel are typically used for crane travel wheels and drum bearings?
GCr15 (most commonly used), corresponding to international standards: SUJ2 / 100Cr6 / 52100; GCr15SiMn has better hardenability than GCr15 and is the preferred choice for large-size bearings; GCr15SiMo / GCr18Mo, with higher purity, are used for non-standard crane bearings subjected to extreme loads and requiring a long service life.
What materials are typically used for crane hooks?
· General-purpose workshop LD/LH cranes, A3–A5: DG20Mn (20Mn2) forged hooks
· Heavy-duty A6/A7, frequent start-stop operations, high-tonnage: 35CrMo forged hooks
· Ports / Metallurgy / A8, low-temperature conditions, extra-high-tonnage double hooks: 34Cr2Ni2Mo
· Metallurgy high-temperature conditions: laminated plate hooks Q355D
