Work Capability Factors for Dozer and LoaderTires Operating in Load and Carry Service 750574

Demands of the earthmoving industry for indepth tire knowledge and performance capabilities has placed increased responsibility on the tire manufacturer for establishing operating limits. The challenge of meeting these demands has resulted in an increasing amount of controlled tire testing conducted under simulated field conditions. One of the areas of required information has been for the establishment of Dozer and Loader tire capabilities when operating in Load and Carry service.
Since tire heat becomes a major potential problem in Load and Carry service, a method was required to determine the performance capabilities of Dozer and Loader tires so that optimum tire life could be achieved. This paper covers the need for tire limits; basic Dozer and Loader tire design requirements; the method established for determining tire capabilities in Load and Carry service, and finally the factors differentiating this rating system from the TMPH system which is used for transport type vehicles.
