  • Dual-stage mounting system for vibratory compactor drum
    Patent number: 5716162
    Abstract: A dual-stage mounting system having an auxiliary support. A first set of elastomeric mounts connects the vibratory compactor drum to the auxiliary support and a second set of elastomeric mounts interconnect the auxiliary support to the vehicular frame. The dual-stage mounting system reduces by more than 70% the vibration transmitted from the drum to the primary support by a single-stage isolation mounting system thereby extending the life of the vehicle and improving operator comfort.
