Hamburg (Immersion) Wheel Trackers

Supports the following standards: AASHTO T324; EN 12697-22; Various State standards

The Hamburg test, or immersion wheel tracking has become an extremely popular test method over the last few years.

The Hamburg wheel tracker is built to withstand the demands of the busiest test labs. It is made of high quality stainless steel, uses the standard cantilevered arm system of loading the specimens and produces fully sinusoidal motion.
In the NCHRP report - Hamburg Wheel-Track Test Equipment Requirements and Improvements to AASHTO T 324, the Cox/Cooper Hamburg was clearly the best performing machine. Since then the heaters and water flow have been uprated, resulting in more rapid heating and improved temperature control.

A number of Hamburg wheel trackers fall purporting to meet the standard fall short of current AASHTO requirements and may fall further behind when the norm is updated. Please be sure to verify the important parameters in the standard are met by the machine. The Cox/Cooper machine meets all the requirements of the standards.
