Abstract
A high-lift lateral dump system for pavement/street sweepers ( ) includes a debris container ( ) positioned between laterally adjacent lift assemblies ( R, F), each lift assembly ( R, F) including a vertically extending upright ( ), a lift arm ( ) that is pivoted at one end to upper end of the upright ( ), and a single-ended double-acting hydraulic lift cylinder ( ) that functions to raise and lower the lift arm ( ). A torque control mechanism ( ) minimizes mis-phasing between the lift cylinders ( ) of each lift assembly ( R, F), and a manual safety stop mechanism ( ) allows an operator to selectively lock the debris container ( ) and the related structural components in the lifted position. An attitude-control system uses hydraulic fluid from the rod end ( r) of the lift cylinder ( ) to maintain the debris container ( ) in a horizontal or near horizontal attitude during the lift cycle.
