The model 8140 S.A.M. truck scale combines the proven reliability of a mechanical lever system with the added benefits of an above ground low profile design. Thurman's 8140 Series are low profile, steel deck truck scales rugged enough to handle a high volume of heavy capacity weighing. This scale achieves its low profile design by allowing the connecting backbone pipe to run outside of the main beams and parallel to the length of the weighbridge. Available in the economical 60K CLC, the heavy duty 90K CLC, and even the extreme duty 120K CLC!
