The bearing device of the crane for constructional engineering comprises a trailer head, a trailer plate is fixedly connected to the lower portion of the right side of the trailer head through a fixing plate, a bearing base is fixedly connected to the top of the trailer plate through a fixing plate, and a cab is arranged on the right side of the top of the bearing base. The invention relates to the technical field of engineering machinery. According to the bearing device of the crane for constructional engineering, the bearing base is installed at the top of the trailer plate, the connecting base and the multi-section air cylinder are arranged in the bearing base, when a first motor is started, the multi-section air cylinder can extend out under the action of a tooth column, but due to the action of a rotating piece, the multi-section air cylinder can naturally droop and is started, and the multi-section air cylinder can be driven to rotate; by means of the arrangement, the extending length of the multi-section air cylinder is reduced, vehicles and pedestrians are prevented from being blocked, and meanwhile the contact area between the multi-section air cylinder and the ground is increased through the supporting bottom plate.

    本发明公开了一种建筑工程用起重机的承托装置,包括拖车头,所述拖车头右侧的下方通过固定板固定连接有拖车板,所述拖车板的顶部通过固定板固定连接有承重底座,所述承重底座顶部的右侧设置有驾驶舱,本发明涉及工程机械技术领域。该建筑工程用起重机的承托装置,通过在拖车板的顶部安装有承重底座,并在承重底座的内部设置有连接座和多节汽缸,当第一电机启动时能够在齿柱的作用下将多节汽缸伸展出去,但由于转动件的作用,多节汽缸会自然下垂并进行启动,使得支撑底板会支撑在地面,此项设置不仅减小了多节汽缸伸展出的长度避免阻挡车辆和行人,同时也通过支撑底板增大与地面的接触面积。
