Auto body tram gauge: 

Our mechanical measuring tram gauge is a high precision tram gauge to measure auto body frame and chassis dimensions for collision repairs. 

Measuring principle: The left-right symmetric comparison method and the three-point one-line observation method. The measuring instrument can measure the height difference of the left and right parts of the chassis very intuitively and exactly, and can measure whether the center line of the car chassis is uniform.

Features:

1. It is small in size, light in weight, easy to operate, fast in measurement speed and short in time, and can be used by a single person.

2. The body of the telescope tram gauge  is made of precision aluminum alloy material, equipped with custom-made horizontal grooves, and the gauge is engraved by laser, with high measurement accuracy.

3. Using the principle of three points and one line, the positioning is accurate, the operation is fast, and the reading is clear at a glance.

4. It can measure the deviation of the body chassis and the girder, with small limitations, and can be used for all models of cars.

5. Hanging bracket, easy to operate, simple and fast.

6. When in use, it can be measured without disassembling and assembling auto parts. This is a time-saving, labor-saving, accurate and fast measuring tool.
