We did receive the scale and it’s working fine. Our employees are really happy, they say it was easy to install, it’s easy to work with, takes little space to store, and it doesn’t take away too much lengtי on our chain sling.  It’s a great product, many thanks !

Here are a few pics.

Balcones Technologies, LLC under contract with the US Army developed vehicle self-recovery poses for a vehicle equipped with an active suspension. The active suspension developed at the University of Texas Center for Electromechanics features high bandwidth controlled actuators on each of the vehicles wheels. A test approach was developed for the self-recovery poses which involved measuring the vehicles drawbar pull capacity while tires are spinning and slipping.  The tests were performed on asphalt, dry grass, and gravel. It was anticipated that the self-extraction poses would provide momentary improvement in the vehicle traction which could be detected by measuring the drawbar pull force. Baseline tests with active suspension off and then test were performed with the suspension while performing various poses. A light weight load cell with dynamic measurement capability was desired which led to the selection of the Ron Crane 4000 load cell. We chose it with the analog output feature and recorded it on the vehicles data acquisition system.  The vehicles 24VDC power  was used to power the load cell.

The Ron Crane load cell worked well in our application.  We were able to collect data at 100 samples/sec and demonstrated ability to cyclically improve vehicle traction

The attached photo shows the load cell in use.
