For over 25 years there has been the claim that a piece of lift 01. loading equipment was defective because of the failure of the manufacturer to install a proximity warning device (PWD). Recently the claims of defect for failure to incorporate a proximity warning device have been expanded to cover additional types of equipment and to incorporate claims of new uses for a device that is effectively the same over this 25-year period, The authors will detail the development of the claims of defect, the development of the details used in the evaluation of the claims of defect and the approach used in the defense of the product that is claimed to be defective without the installation of the proximity warning device. They will in this report further detail the test program that became a part of the development of data for a concrete placing pump product liability defense.
