FIELD: construction industry. SUBSTANCE: loading equipment has manipulator, manipulator raising-lowering hydraulic cylinders, rear jaw pivotally connected to front jaw, and double-armed lever coupled to rear jaw. Rear jaw rotating hydraulic cylinder is connected to one arm of double-armed lever and pivotal tie-rod is connected to other arm of this lever. Auxiliary pivotal tie-rod has one end coupled to front jaw and other end coupled to pivot joint, which connects double-armed lever to manipulator. Longitudinal axis of auxiliary tie-rod is extending at higher level than jaw connecting pivot joint. EFFECT: increased efficiency and simplified bucket jaw control. 2 dwg
