Abstract
A load handling vehicle includes a bucket side tilt mechanism with a supporting H-framework comprised of first and second side frame members and a cross-frame member. The side frame members are each coupled at a first end to the body of the vehicle and at a second end to the bucket, while the cross-frame member is pivoted at each end to a respective one of the side frame members so that the cross-frame member pivots during tilting of the bucket and relieves stress on the framework. A pair of dump cylinders coupled between the framework and bucket are provided for emptying the bucket. In addition, a hoist cylinder extends between the framework and the body of the vehicle, at each side of the vehicle, for raising and lowering the framework and thereby the bucket. A tilt cylinder is tandem with one of these hoist cylinders is extended and retracted to tip the framework and in turn tilt the bucket relative to horizontal as desired. A low-pressure relief mechanism is provided for relieving hydraulic pressure at the bucket side of the dump cylinders to minimize stresses applied to the bucket as the tilt cylinder operates.
