description

The AV280 Pin Cover adopts upgraded thickened high-density modified rubber-plastic composite material, with thicker wall thickness and higher structural rigidity than ordinary pin covers. It balances super elasticity and strong tensile & tear resistance, no permanent deformation under long-term extrusion and vibration of large excavator working devices. The product is added with anti-UV and anti-aging auxiliary ingredients, with upgraded surface anti-fouling and anti-corrosion treatment, which can adapt to harsh working environments such as quarry heavy excavation, long-term open-air exposure and muddy water impact. The optimized large-size wrapping structure is designed for the large gap of large-tonnage pin shafts, with higher fitting degree and better overall dust-proof and mud-proof performance. It completely covers the matching gap between pin shaft and bushing, keeps internal lubricating grease clean, avoids dry friction and abnormal wear. All finished products pass strict dimensional calibration, elasticity test and fatigue resistance test, with stable quality and strong interchangeability, which is a special heavy-duty protective wearing part for large excavators.

advantages

  • Thickened Reinforced Heavy-duty Structure: Adopts exclusive thickened wall design for large excavators, solving the defects of thin and fragile ordinary pin covers. It is resistant to heavy extrusion and impact of large working devices, no cracking or tearing under long-term heavy-load operation.
  • High-strength Modified Material Upgrade: The upgraded rubber-plastic formula greatly improves tensile strength and anti-fatigue performance. It adapts to all-day high-frequency operation of large excavators, not easy to harden and age, and maintains stable elasticity and sealing performance.
  • Super Dust-proof & Mud-proof Ability: Optimized large-range wrapping structure, perfectly fits the large gap of large-tonnage pin shafts, effectively blocks heavy mud, sand and fine dust intrusion, thoroughly solves the problem of easy ash entry of ordinary protective covers for large excavators.
  • Effective Protection for Large Pin Shaft Assembly: Keeps the internal lubrication environment of large pin shafts clean, avoids dry friction and bushing scratching caused by dirt accumulation, significantly reduces the failure rate of pin shaft jamming and working device jitter of large equipment.
  • Strong Environmental Adaptability: Enhanced anti-UV and anti-corrosion performance, resists harsh environments such as strong sunlight, rain erosion and muddy water scouring, suitable for long-term outdoor open-air construction.
  • Cost-saving & Efficient Maintenance: Special for large excavators with high matching accuracy. Snap-on installation without tools, effectively reduces frequent replacement frequency of ordinary thin-type pin covers, and cuts long-term maintenance costs.

FAQ

  • Q1: What is the difference between AV280 and ordinary AV107 pin cover?
  • A: AV107 is a universal standard model for 12–25 ton excavators, suitable for conventional light and medium working conditions. The AV280 is a thickened heavy-duty upgraded version, specially customized for 25–35 ton large excavators, with thicker wall, higher strength, better mud resistance and longer service life, focusing on heavy-load harsh working conditions.
  • Q2: Can AV280 be used on medium and small excavators below 25 tons?
  • A: It can be installed optionally, but the AV280 has a larger wrapping range and thicker structure, which is more biased towards large excavator heavy-load protection. For 12–25 ton conventional models, AV107 standard model is more cost-effective and fits better.
  • Q3: How to identify that heavy-duty pin cover replacement is required?
  • A: For 25-ton and above large excavators, if the original pin cover is frequently torn, deformed or has poor dust-proof effect under heavy-load operation, it needs to be upgraded and replaced with AV280 heavy-duty thickened model.
  • Q4: Does AV280 installation require modification?
  • A: No modification is required. It adopts standard snap-on size for large excavators, plug-and-play, tight fit after installation, no loosening or falling off.
  • Q5: Why are large excavators more suitable for AV280 heavy-duty model?
  • A: Large excavators have larger pin shaft gaps, heavier working device impact and harsher working conditions. Ordinary thin pin covers are easy to damage and fail. AV280 thickened upgraded version can cope with high-intensity operation and provide long-term stable protection.
