Axle Load Equipment

Axle load surveys provide invaluable and essential information that are required for cost effective pavement design and preservation of the existing roads. ACC have their own SAW III – Portable Dynamic Scale System  in order to undertake the Axle Load Survey of the existing roads. Applications and Advantages of SAW III – Portable Dynamic Scale System are:

Applications:

  • Dynamic measurement for overload indication
  • Dual-scale system configuration with computer-based processing for reporting, protocol printing and data archiving.

Advantages:

  • Both for static & dynamic weighing operation
  • Pre-selection of overloaded trucks
  • High vehicle throughput
  • High accuracy
  • Very efficient weight enforcement
