Overview

The ABT 4640 is a light-weight gauge that allows the user to safely take Height

and Stagger measurements of the OHL (Over Head Line) using laser technology.

Super-Elevation (SE) and Rail Edge to Face of Structure (REFOS) can also be

measured

The laser unit is positioned at eye-level and features a 90º viewing prism, enabling

the operator to easily set the laser location marker onto the OHL in all weather

conditions including bright sunshine. The Height reading is displayed on an

illuminated LCD screen on the laser. Stagger position is indicated on a reflective

scale for ease of use at night as well as day.

SE is displayed on an illuminated LCD screen and REFOS is measured by

transferring the laser unit to a separate bracket

The vertical beam folds down flat to the horizontal beam for storage and transport.

Assembly

To release the vertical beam, pull the lever towards you (See Figure 1).

Lift the vertical beam until it rests against the stop. Release the toggle

latches and fasten securely to the vertical beam (shown in Figure 2).

Additional laser units can be purchased to remove the requirement to swap laser positions when

measuring REFOS
