Heavy Off-Road Testing - Clark Testing

Heavy Off-Road Testing



Clark Testing brings years of experience in component testing and product validation for the heavy equipment testing. Clark’s lab in Michigan includes one of the largest structural mass test floors in the US with a structural capability of 1.5 million pounds. In addition to its structures floor, we can custom design test programs with multiple hydraulic systems and strong backs. Hydraulic power supplies combined with our large inventory of hydraulic cylinder with load capacities in excess of 2 million pounds.

In addition to our structural load capabilities, Clark has large shaker systems, dynamometers, thermal chambers and rotary fatigue test systems that are designed for large capacity and dimensions geared to the heavy equipment industry. We conduct our test programs under s stringent 17025 quality program utilizing the latest control and data acquisition instrumentation to ensure reliability and accuracy.

OSHPD Image

Seismic OSHPD Testing

California’s Office of Statewide Health Planning & Development requires products to pass unique and intense seismic testing under ICC Evaluation Service acceptance criteria. Due to the state’s geology, the OSHPD requires that tests be performed according to soil class and seismic profile. We tested the above 9,000 lb., 15(l) x 5(w) x 12.5(h) ft. unit for soil class D at an SDS level of 2.50, translating to an AFLX-Horizontal level of 3.2 g and -Vertical level of 1.68g. The table can generate up to 5g on units weighing 2,000 lbs. and has an overall capacity of 20,000 lbs., making it one of the largest triaxial seismic tables in the world.
