Pit Type Mechanical Truck Scales are installed in pit. The Rice Lake SURVIVOR PT-M is a mechanical pipe-lever design of the pit-type PT model. The mechanical lever system is precision-built from heavy-duty structural steel to provide higher strength and less stress breaks than competitive components. These mechanical scales are designed with a load cell inserted into its lever system. These levertronic designs are better suited for areas susceptible to heavy moisture. The in-ground installation is ideal for locations with limited space or access. It may also be installed above ground for special site applications. The PT-M is a cost effective investment for a long term, permanent installation, providing the highest accuracy with the lowest maintenance costs. Available in both steel and concrete decks and constructed with the same massive I-beams that support our PT and SR designs, the PT-M is a solid investment for many pit-type applications. We also offer electronic pit style truck scales.
