Abstract
The present invention is directed to a mechanism for angularly centering a boom structure as it is being elevated from a lower operating position to an elevated, transit position. A boom structure is pivotally mounted on a pin member. A hydraulic cylinder moves the pin member and the boom structure upwardly or downwardly. As the boom structure is moved from a lower, operating position to an upper, transit position, a pair of chains, one attached between the boom structure and the vehicle holding it on each side of a vertical plane passing through the pin member, self-centers the boom structure.
