Means to reduce oscillatory deflection of vehicle

Abstract From the Canadian patent

Abstract of the Disclosure A rough terrain vehicle comprises a vehicle chassis resilient terrain-engaging wheel assemblies connected to the chassis and enabling vertical and angular deflection of the chassis relative to the terrain during vehicle movement a, telescopic crane boom carried by the chassis a pivot pin, for connecting the boom to the chassis and enabling limited reciprocable angular deflection of the boom relative to the chassis as the vehicle moves across supporting terrain and a hydraulic boom hoist cylinder to raise and lower the boom. A deflection reduction system is connected between the chassis and the boom to reduce or eliminate vertical and angular deflection (bouncing …
