ABSTRACT:
A rollover protective structure (ROPS) for use with construction machinery includes a base, four upright posts attached to the base and cross members attached between the posts to define generally a box-like structure. Two of the posts define a forward side of the structure. The other two posts define opposing ends of the structure. First and second reinforcing members are attached within the first and second posts to the forward sides, respectively, for selective reinforcement of the forward sides. Third and fourth reinforcing members are attached within the third and fourth posts to the opposing ends for selective reinforcement of the opposing ends, respectively. The first and second reinforcing members extend between the base member and cross member, and the third and fourth reinforcing members extend between the base member to above the cross member.
