Abstract

Roller compactors exhibit a high resistance to rollover which may be attributed to their low center of gravity, full width rollers, low speed, responsive braking system, high visibility, and operator profile. Tilt table testing of an Ingram pneumatic roller compactor demonstrates that its lateral stability normally exceeds or is comparable to other workplace vehicles. To eliminate or mitigate injuries resulting from roller compactor rollover excursions, a rollover protective structure (ROPS) and seat belt system has been widely debated as a proper countermeasure. Clearly, the roller compactor accident statistics demonstrate the potential of unbelted operators to suffer serious injuries inflicted by the ROPS safety device itself. In the face of reported low seat belt usage, the utilization of the ROPS and seat belt as standard equipment on a roller compactor is not straightforward and value systems are struggling with this dilemma.
