CouplerView-Pin

F-Type coupler securement inspection


Trimble® CouplerView®-Pin is an automatic coupler pin carrier plate inspection system that inspects F-type coupler securement mechanisms using high-speed and high-definition imaging at mainline operational speeds.

Automated inspection of coupler securements to minimize derailments

The system utilizes high-speed digital line imaging cameras to acquire multiple images of every coupler pin securement for inspection. For F-type couplers, the system inspects the coupler vertical pin carrier plate, securement, and the corresponding fasteners. Different types of F-type securements, including ones with cushioning units, are handled as well.

If the coupler securement fails during train operation there is a high probability that the coupler will “pull out” of the car in a draft situation. In most cases this will result in the coupler falling between the cars and into the gauge of the track. If the train is operating at mainline speeds this can result in a derailment.

Sophisticated image processing with alarms that alert to issues

CouplerView-Pin is designed to operate on passing trains at mainline operational speeds of up to 60 mph (100 km/h). The CouplerView-Pin system’s processing algorithm classifies couplers into E and F types before the securement processing and only F-Type couplers are inspected.

CouplerView-Pin systems are installed on steel ties (sleepers) supplied by Trimble. Cameras and the illumination system are enclosed in sealed steel boxes mounted on the gauge side of the supplied steel tie (sleeper). The securement component images are analyzed for possible failure, deformation, and missing fasteners, and plates.

Dramatic time and cost savings, versus manual inspections

Automate and complete F-type coupler pin securement mechanism 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

CouplerView 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 CouplerView reduces manual and paper-based workflows saving time and money. Critical issues are flagged and reported automatically so that corrective actions can be taken with less impact on service.

Easy to install system minimizes disruption and cost

CouplerView requires no track structure modification for ease of installation.

Inspections & Measurements

Trimble CouplerView-Pin system inspections and measurements include:

  • Classification of E-type and F-type couplers.
  • Missing coupler pin plate detection.
  • Leaning coupler pin plate detection.
  • Missing fasteners detection.
  • Rotated coupler pin plate detection.
  • Combination of any of the above.

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