Field Diagnosis & Quick Fixes for Road Sweeping Attachments
During intense road construction schedules, equipment downtime can delay bitumen spraying and asphalt paver operations. Knowing how to diagnose and resolve hydraulic broomer issues on site ensures continuous workflow and protects hydraulic components from severe damage.
Symptom 1: Broom Core Rotates Slowly or Stalls Under Load
Possible Causes:
- Low Hydraulic Oil Flow: Check tractor or loader auxiliary hydraulic flow settings. Ensure quick-disconnect couplings are fully engaged.
- Worn Hydraulic Motor Seals: Internal bypass in the hydraulic motor reduces output torque. Replace motor seal kits or orbital motor assembly.
- Excessive Ground Pressure: Operator has lowered the broom too far, causing mechanical binding against the road surface.
Symptom 2: Severe Shaft Vibration During Operation
Possible Causes:
- Imbalanced Brush Core: Uneven bristle wear or missing brush wafer segments create centrifugal imbalance. Replace worn sections to restore balance.
- Bent Main Shaft or Worn Bearing Blocks: Inspect end bearings for play and replace pillow block bearings if play exceeds 1.5mm.
Symptom 3: Rapid Bristle Melting or Deformity
Possible Causes:
- Sweeping on freshly hot-milled asphalt surfaces without water spray cooling.
- Using low-grade recycled poly bristles with low thermal melting points. Upgrade to virgin polypropylene heat-resistant broomer brushes.
