600 Ton Test Stand

C.H. Bull Company, recognizing the needs of our customers, engineered, designed and fabricated a 600 ton (1,200,000 pound) test stand. Calibration of the large tonnage jacks can take weeks in some cases. We are able to respond to our customers’ needs in days.

PREPARING TO CALIBRATE A 500 TON TEST STAND

Caltrans and other states transportation departments and many government agencies require the hydraulic jacks to be calibrated. Jobs that often require calibrations would be pile testing and when lifting or supporting a bridge. Currently we have the capability to calibrate jacks through the full range of the jack up to 500 tons with a 1,000,000 pound load cell. Other facilities might only be able to test to 100 or 200 tons and then extrapolate the calibration to 500 tons.
