GMH Engineering is the innovative leader in amusement ride testing. First, GMH Engineering developed the DataBRICK data acquisition system that is used by amusement parks, by roller coaster manufacturers, and by engineering firms specializing in roller coaster testing. Next, GMH Engineering developed the Delta DRS1000 Non-Contact Speed Sensor for the continuous measurement of roller coaster speed. This innovation was critical for accurately correlating the data gathered to an exact position on the track. Instead of telling an amusement park, or a manufacturer, that they may have a potential problem 27 seconds into the ride, GMH Engineering pinpoints the exact spot on the track.

	Regular testing of roller coasters should be part of every maintenance program. New test data should be compared with previous data to look for changes or for developing trouble spots. With regular testing, maintenance dollars can be targeted to where they will be most beneficial. Plus, having well documented test data on file is essential in case of law suits. A well maintained ride is the best insurance one can have.

After a long day of testing g-forces, Fred, our crash test dummy, likes to go on a few rides just for the fun of it. The picture to the left shows Fred holding his hands up as he goes over the first hill.
