Stanray Underfloor Wheel Truing Machine

Upon receipt of an old machine, the unit is completely disassembled. All piping and wiring as well as worn parts are replaced. The steel castings are cleaned and inspected, built up by welding, and then completely re-machined to the latest OEM specifications. Purchased components as well as manufactured parts are thoroughly inspected. All new hydraulic valving, piping, and actuators as well as new electric motors, controls, and wiring are installed. Sub-assemblies are functionally checked, and the final assembly is factory and site tested to assure that it meets Simmons’ and the customer’s expectations.
