The invention provides a crane for building. The crane structurally comprises a hanging bracket structure, a mover, a hoisting machine, a fixed seat and a movable chassis,wherein the mover is installed on the hanging bracket structure and is in sliding connection with the hanging bracket structure, and the lower end of the mover is welded to the upper end of the hoisting machine. According to thecrane, a buffering support plate structure is arranged, through the buffering effect of first buffering springs on thrust generated by a pushing and pressing plate, the situation that the position ofthe joint of the buffering support plate structure and a stand column is damaged due to too large pushing force is avoided, the temporary limiting and fixing effect on the joint is achieved, thereforea transverse rod can be effectively prevented from directly falling down, a warning structure is arranged, so that a warning ball is not limited by an upper sealing cover, the warning ball can be automatically ejected out under the action of a return spring, the warning effect on the worker is achieved, and the situation that the worker cannot receive the situation that the transverse rod inclines in time and cannot conduct treatment in time so as to cause a series of hidden dangers is avoided.
本发明提供一种建筑用的吊车,其结构包括吊架结构、移动器、起吊机、固定座、移动底盘,移动器安装于吊架结构上且滑动连接,移动器下端与起吊机上端相焊接,本发明通过设置缓冲支架板结构,通过第一缓冲弹簧对推压板所产生的推力进行缓冲的作用,避免推动力太大,造成缓冲支架板结构与立柱连接缝位置受损,且达到暂时性的对其进行限位固定的作用,从而能够有效的避免横杆直接掉落下去,对建筑器件及工作人员造成伤害,通过设置警示结构,使得警示球不在受上封盖的限制,警示球在回位弹簧的作用下,将会自动的弹出,以此对工作人员进行警示的作用,避免工作人员未能及时的接收到横杆发生倾斜,而未能及时的做出处理,造成一系类的隐患存在。
