Синтез направляющих механизмов для навесного крана

Abstract

The boom lifts of mobile machine assemblies are hinged lever systems with a hydraulic drive. For two-level loading of containers, the executive hook suspension must move strictly vertically. To this end, methods of exact and approximate synthesis of directing mechanisms with an extended rectilinear section of the trajectory are proposed. The optimal position of the power cylinder, providing approximately uniform motion of the executive point, is substantiated. For the forklift truck, a parallelogram system is provided, giving the executive body a strictly translational motion.
