More Information
Summary:The utility model relates to a device which provides a safety protection measure for a discharging platform used for a construction lifting frame. The utility model aims at changing a common manual driving simple sliding door into a mechanical driving normally closed folding door. The utility model is characterized in that a door body (10) is connected with a head pulley (6) by a working steel rope (3), and is connected with a bobweight block (9) by a bobweight steel rope (11). A bracket (2) is used as the upper stopping point of the bobweight block (9). The head pulley (6) and a movable pulley set (5) are matched to be used. The device which provides a safety protection measure for a discharging platform used for a construction lifting frame not only eliminates the potential safety hazard existing on the discharging platform, but also can not baffle building construction.
