  • Patent number: 5794852
    Abstract: A boom assembly is provided for use on a vehicle. The boom assembly utilizes various suspension components which absorb and damp a significant amount of various loads imparted on the boom assembly during operation of the vehicle. The boom assembly reduces the loads imparted on the booms when the vehicle pitches and rolls. By reducing the loads created by vehicle pitching and rolling, the booms receive a softer and smoother ride which increases the lifetime of the booms and lengthens the time between repair of the booms.
