I. Overview

The insulated rail straightedge is primarily used for horizontal alignment, vertical alignment, and apex adjustment of rail ends during thermite welding of rails. It can also be employed to detect the surface wear flatness of rails. The ruler body is made of high-quality aluminum alloy material, the measuring surface utilizes wear-resistant and high-temperature-resistant insulating material, and the scale markings are produced using laser engraving technology, ensuring clear indications and high accuracy.

II. Main Technical Parameters

III. Usage Instructions

Before use, check the product's condition for any defects. Clean the measuring surface of the main ruler and inspect all parts for wear and dirt. Then, gently and steadily place the straightedge on the surface of the workpiece to be measured, and use a feeler gauge to detect the gap between the measured object and the straightedge.

IV. Usage Precautions

l Avoid severe collisions with any part of the tool during use and transportation to prevent damage.

l When not in use for an extended period, store the rail straightness measuring ruler in its packaging box.

l If the product is subjected to collision or dropped, it should be sent to the metrology department for inspection and only used after passing the test.
