| Mine Roof Simulator |
The Mine Roof Simulator provides unique capabilities to evaluate the integrity, stability, and load performance characteristics of large specimen structures and equipment. The simulator´s biaxial load frame can accommodate specimens up to 16 feet high, 20 feet wide, and 20 feet long. Precision load testing is achieved by closed-loop, servo controlled actuators with six degrees of freedom control of the lower platen. Up to 3 million pounds of vertical force can be applied through a 24-inch stroke of the lower platen. Horizontal loads of up to 1.6 million pounds can be applied simultaneously by horizontal displacement of the lower platen through a 16-inch stroke.
