Brake air hose inspection

Trimble® AHView is an automatic brake air hose inspection system that inspects all air hose arrangements using high-speed and high-definition imaging at mainline operational speeds.

Inspection and measurement of air hose arrangements, at mainline speeds, even in tough environments, day or night

Diagnosis of air hose separation to minimize train stoppage

AHView wayside brake air hose inspection system provides high resolution images of every air hose arrangement for inspection and measurement. Air hose arrangements and their diagnosis is complex and an automated system is highly beneficial for rail operators as air hose separation is one of the leading causes of train stoppage in freight operations.

Sophisticated image processing with alarms that alert to issues

AHView provides automated alarms based on the condition of the air hose arrangement and detects the ones that have the highest probability of separation. It is designed to inspect many conditions of the air hose assembly and can detect defects like peaked air hose coupling, air hose height, glad-hand, air hose angle, coupling position, and more.

Dramatic time and cost savings, versus manual inspections

Complete brake air hose inspections quicker, minimizing time taken, costs, and issues that disrupt service.

Rolling stock stays in service for longer

With accurate measurements at mainline operational speeds there is minimal disruption to rolling stock schedules.

Limits risk to personnel, works 24/7, even in tough environments

AHView works in even the toughest environments and at night so field workers are not in unpleasant or unsafe working conditions thereby reducing the risk to their safety.

Digital accurate records, with automated alerts of issues

Providing digital records that are usable across operations and maintenance AHView reduces manual and paper-based workflows saving time and money. Critical issues are flagged and reported so that corrective actions can be taken with less impact on service.

Inspections & Measurements

Trimble AHView system inspections and measurements include:

  • Air hose orientation.
  • Air hose angle.
  • Air hose height from top of rail.
  • Glad-hand angle.
  • Alarm on peaked and horizontal coupling.
  • Air hose support inspection.
  • Coupler shank movement.
  • Coupler height.

Depending on the rolling stock types and requirements, the system’s inspection and measurement outputs may require optimization or customization.
