Heavy Vehicle Event Data Recorders (HVEDR)

Mecanica is one of four North American authorized service providers for Volvo and Mack data imaging.

Electronic Repairs & Chip Transfer

  • • Mecanica’s forensic electronics/electrical team has extensive experience in recovering data from damaged electronic assemblies including Electronic Control Units (ECU) whose memory chips may contain “blackbox” or Event Data Recorder (EDR) data.
  • • ECU’s can be damaged due to vehicle crush or thermal damage from fire, or water damage due to submersion.
  • • Mecanica’s electronics lab team are certified by IPC for 7711c and 7721c – Rework, Modification and Repair of Electronic Assemblies

Mobile Device Analysis (Cellebrite Tool)

Mobile Device Forensic Data Recovery & Analysis

● Universal Forensic Extraction Device
● Cell phones / tablets / mass storage devices
● GPS data history (position history)
● Phone call logs / Text message history
● Social messaging apps (WhatsApp, Kik, etc.)
● Digital photo and video recovery
● Incident-specific analysis (timeline)
● Analysis and incorporation with vehicle GPS based telematics data
● Incorporation into traditional crash reconstruction methodologies

Mobile Performance Based Brake Tester (PBBT)

PBBT’s allows a brake inspection to go above and beyond a visual inspection or mechanical inspection that is limited to the air brake chamber stroke measurement. The use of a Performanced-Based Brake Tester (PBBT) provides an actual quantitative measurement of the amount of brake force being generated at each braked wheel in 20 minutes or less.

The use of a PBBT as reported by the Commercial Vehicle Safety Alliance (CVSA) can help a fleet determine the following:

  • ● Evaluate which brake linings are appropriate for a fleet’s operations
  • ● The sources of uneven brake lining wear
  • ● Possibly determine the source of uneven tire wear
  • ● Root cause of air valve problems and other air system problems
  • ● Brake balance problems
  • ● Whether or not a vehicle involved in an accident had adequate braking capability
  • ● Whether or not the vehicle meets the minimum Department of Transportation (DOT) regulated brake performance standards

The Performance-Based Brake Tester (PBBT) is a dynamometer that can make direct measurements of brake forces at each axle end of a vehicle.
