Abstract
The present invention provides a rollover protection structure that utilizes unitary corner members that are cast pieces that require no additional bracing. In addition, each corner member includes a leg portion that integrally defines an area of reduced cross-section. This reduction in cross-section creates an area of predictable deformation in the structure which will prevent the structure from collapsing on an operator stationed within the cab.
