Abstract
A suspension assembly for securing a wheel to opposed sides of a container carrying frame. A pivoted wheel support arm is secured at a forward pivot end to a pivot pin retained in the frame. A wheel axle assembly is secured at the rear free end of the pivot arm and adapted to connect a wheel thereto and has a shock absorber connecting bracket. A shock absorber connecting member extends above the pivot pin and is pivotally displaceable in facial alignment with a stationary shock absorber connector secured to the frame. A shock absorber is retained captive between the shock absorber connecting member and the stationary shock absorber connector to absorb vertical displacement loads transmitted to the pivotal wheel support arm.
