Construction Machinery Parts: Long-Life Hydraulic/Structural Parts
Welcome to explore JOC Machinery’s Construction Machinery Parts! We cover excavators, loaders, cranes, and focus on wear-resistant chassis, buckets, hydraulic parts—ideal for mining, heavy-duty work. Custom solutions and in-stock supply are available, bringing reliable performance to your projects.
Products Introduce
JOC Machinery’s Construction Machinery Parts are built for harsh construction environments, fitting excavators, loaders, and cranes to cut downtime from wear, shock, or corrosion. Our key components include wear-resistant buckets (high-manganese steel + heat-treated boron steel, hardness ≥ HRC55), undercarriage parts (rubber track pads), leak-proof hydraulic fittings, and specialized wear parts (e.g., alloy steel crusher hammers). With 30%-50% longer life than standard carbon steel, 1000+ hours salt spray resistance for coastal sites, and batch interchangeability, they suit mining (reinforced parts), coastal (corrosion-resistant) and urban (quiet track pads) projects. We offer in-stock standard parts (48-hour delivery) and custom solutions (72-hour quoting from drawings) for all scales.

Product Advantages
To clearly highlight the core competitiveness of JOC Machinery’s Construction Machinery Parts, we summarize its advantages around two key dimensions that matter most to construction operations:
Superior Material & Performance (Long-Lasting Reliability)
JOC’s Construction Machinery Parts stand out with durability-focused designs: Made of high-manganese steel (shock resistance) and heat-treated boron steel (cutting edge hardness ≥ HRC55), they offer 30%-50% longer service life than standard carbon steel parts. For harsh environments, special protective coatings pass 1000+ hours of salt spray testing (ideal for coastal/chemical sites), while dimensional jigs ensure batch interchangeability—parts can be directly replaced without reworking, cutting maintenance time.
Scenario Adaptability & Flexible Supply
Tailored to diverse construction needs: Reinforced parts for mining/heavy-duty work, corrosion-resistant components for coastal projects, and quiet rubber track pads for urban infrastructure (protecting roads). Supply is equally flexible: Standard parts (e.g., track pads, buckets) are in-stock for 48-hour delivery, and custom solutions (via drawings) come with 72-hour quick quoting—supporting both small batches and large-scale project demands.
Technical Specifications
To provide clear, actionable performance references for your equipment matching and procurement decisions, the technical specifications of JOC Machinery’s Construction Machinery Parts are detailed below from three core dimensions—material performance, dimensional precision, and working condition adaptability—covering key indicators that directly affect part durability and compatibility:
Material Performance Parameters
Wear-Resistant Materials: Cutting edges and bucket bodies use heat-treated boron steel (hardness ≥ HRC55) and high-manganese steel (Mn content: 11%-14%), with impact toughness ≥ 18J/cm² (at -40℃) for resistance to crushing and deformation. Corrosion-Resistant Coatings: Components for coastal/chemical scenarios adopt epoxy zinc-rich primer + polyurethane topcoat, with coating thickness 80-120μm; salt spray resistance ≥ 1000 hours (per ASTM B117 standard), no rust or peeling. Hydraulic Component Materials: Hydraulic fittings are made of 304 stainless steel (for low-corrosion environments) or carbon steel with chrome plating (surface hardness ≥ HV800), ensuring pressure resistance up to 35MPa without leakage.
Dimensional & Precision Standards
Interchangeability Tolerance: Key components (e.g., undercarriage rollers, cutting edges) follow ISO 8062 H9 tolerance grade; batch size deviation ≤ ±0.3mm, enabling direct replacement without on-site reworking. Structural Fabrication Precision: Welded parts (e.g., bucket frames) use robotic welding (welding seam height ≥ 5mm) + NDT ultrasonic testing (no internal defects ≥ φ3mm); 3D scanning fitting accuracy ≤ 0.5mm, matching original equipment dimensions. Standard Part Sizes: Common products cover mainstream specifications—rubber track pads (e.g., 250×70mm, 300×80mm), hydraulic connectors (1/2" to 2" NPT threads), and crusher hammers (weight range: 5kg-50kg) for immediate compatibility.
Working Condition Adaptation Parameters
Load-Bearing Capacity: Mining-specific reinforced buckets can withstand maximum impact loads up to 80kN; undercarriage parts (e.g., track links) have static load capacity ≥ 300kN, suitable for heavy-duty operations like ore loading. Temperature & Environmental Adaptability: Parts maintain performance in -30℃ to 80℃ ambient temperature; rubber components (e.g., track pads) use EPDM rubber (aging resistance: ≥ 5 years outdoors), avoiding hardening or cracking in extreme weather. Noise & Road Protection: Urban-use rubber track pads have a noise level ≤ 75dB (at 5km/h), 15dB lower than steel tracks; surface anti-slip patterns (depth ≥ 3mm) prevent skidding while protecting asphalt/cement roads from scratches.
Application
Mining & Quarry Operations
Tailored for high-wear, heavy-impact environments like ore extraction and stone crushing. Key applied parts include reinforced buckets (made of high-manganese steel + boron steel cutting edges) for digging hard rock, alloy steel crusher hammers (impact toughness ≥ 18J/cm²) for crushing ore, and undercarriage components (static load capacity ≥ 300kN) that resist deformation from heavy loads. These parts solve common issues like frequent bucket edge wear and crusher hammer cracking, reducing maintenance frequency by 30% for mining fleets.
Coastal Infrastructure Projects
Ideal for coastal roads, ports, and offshore engineering where saltwater corrosion is a major threat. Applied components feature corrosion-resistant designs: hydraulic fittings made of 304 stainless steel, structural parts with epoxy zinc-rich coatings (salt spray resistance ≥ 1000 hours), and rubber track pads with anti-aging EPDM material. They prevent rust-induced leaks in hydraulic systems and extend part life in humid, salt-laden air—critical for long-term coastal project stability.
Municipal & Urban Renewal
Adapted to urban construction needs like road repair, building demolition, and subway construction. Quiet rubber track pads (noise ≤ 75dB at 5km/h) minimize disturbance to residential areas; clip-on rubber pads protect asphalt/cement roads from scratches during equipment movement. Additionally, standard parts (e.g., small-sized hydraulic connectors, light-duty bucket edges) are in stock for 48-hour delivery, supporting the fast-paced schedule of municipal projects that require quick part replacements.
Customized Special Engineering
Serves niche scenarios with bespoke solutions. For example: waste treatment plants use wear-resistant alloy steel crusher rotors (custom-sized via drawings); high-altitude infrastructure projects adopt low-temperature-resistant undercarriage grease (maintains performance at -30℃); water conservancy projects use stainless steel investment-cast water meter components (corrosion-proof for long-term water contact). All custom parts come with 72-hour quoting, matching the unique needs of non-standard engineering.
