Abstract

A lid operation arrangement of a container includes an automatic operated unit for automatically operating a lid panel, a foot operated unit for manually operating the lid panel, and a motorized unit operatively linked with the automatic operated unit and the foot operated unit. When the motorized unit is activated by the automatic operated unit, the motorized unit is arranged for generating a torque enhancing force to move the lid panel from the opened position to the closed position and for generating a decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner. After the lid panel is lifted up to the opened position by the foot operated unit, the motorized unit only generates the decelerating force to move the lid panel back to the closed position from the opened position in a hydraulic manner.
