Technical Features
High-yield steel plate forms a rigid barrier that deflects rocks and debris away from rollers, idlers, and track links.
Reinforced gussets and full-length seam welds distribute impact stress evenly, preventing bending, cracking, or bolt loosening under continuous track vibration.
Factory-applied anti-corrosion primer and optional hardfacing on wear edges extend service intervals in abrasive mining and quarry environments.
Applications
- Mining: Protects undercarriage components from sharp ore and rock spillage.
- Road Construction: Reduces wear in crushed aggregate and milled asphalt conditions.
- Quarrying: Prevents rock ingestion between track links and rollers.
- Demolition: Shields track systems from concrete debris and reinforcing steel.
- Forestry: Guards against stumps, branches, and hidden ground obstacles.

Maintenance Guide
- Installation: Confirm bolt hole alignment; torque all mounting bolts to Doosan specifications and apply thread-locking compound.
- Routine Inspection: Every 250 operating hours, check for cracks, deformation, missing bolts, and excessive wear-edge thinning.
- Wear Replacement: Replace if wear-edge thickness is reduced by 30% or if mounting holes become elongated or cracked.
- Service Interval: In abrasive conditions, inspect monthly; typical replacement ranges from 3,000 to 5,000 hours depending on application.
