Surveying Targets

Pathfinder manufactures and produces two target systems for use in railway and structure surveying & monitoring environments:

1) EDM Target System

The EDM Target System is an innovative product design which offers safety and efficiency gains for engineers working in the rail industry. The features of the EDM system benefit engineers by providing a simple to use, durable and high accuracy system at a reduced cost. The target comprises of five components as can be seen in the image to the left.

The components are:

  * Base Plate — Fixes EDM Target system to rail and when  applied with approved adhesive, will securely adhere to any surface, wet or dry.
  * Target (or flag) — Provides a high quality reflective surface which can be easily targeted by the EDM system. The target has twelve directional settings so the flag can be positioned and repositioned to face any direction without disturbing the base.
  * Hood — Reduces glare from light source other than EDM and protects surface of prism from rain and debris prolonging the efficient operating life of the target.
  * Wedge — Snaps into the base plate and positions the prism at the optimum reflective angle on high canted rail. The same mechanism is used to improve the accuracy of acute angle close proximity readings.
  * Plug — Should a site lay dormant for a long period, the flags and prisms are removed and the plug applied. This protects the base plate from damage and fouling indefinitely. A site can the be re-opened at any time without additional effort. Read more

2) Rapid Rail Target System

The Rapid Rail Target System is a popular variant of our EDM target system. Innovative design features mean that it is suitable for application to the rail flat bottom and bullhead rails.

Unlike its predecessor, it is positioned in the web of the rail which makes it  highly suitable for particular application situations. It is also very  easy to use being a single component. These features have combined to make the Rapid rail target system a popular choice of engineers working on site.    Read more
