COVERING SYSTEM OF A TRUCK

摘要

An apparatus for opening and closing a cover of a truck is disclosed. The apparatus includes a rotatable shaft that can be connected to multiple supports in order to provide a torsion force to each of the supports to pivotably rotate the supports and the cover between an opened position and a closed position. The shaft is hexagonal in cross-section. The supports are attachable to the cover and are pivotably attached at an end of each support to a side of the container, for supporting the cover and moving the cover between an open position and a closed position. A plurality of hinges are used to pivotably attach the supports to the container and to rotatably receive the shaft proximate to and parallel to the one side of the container. An actuator is used to provide rotary motion to the shaft. The actuator includes a hydraulic cylinder and a chain and sprockets for converting linear motion of the cylinder to rotary motion of the shaft.
