The invention relates to the technical field of cargo booms, in particular to a cargo boom for a crane, which comprises a first boom section, the rear side of the upper end of the first boom section is fixedly connected with a fixing seat, the upper end of the fixing seat is fixedly connected with an air blower, the front end of the air blower is fixedly connected with a pressurizing air pipe, and the front end of the pressurizing air pipe is fixedly connected with a heating treatment box. A heating chamber is formed in the rear side in the heating treatment box, and an electric heating pipe is fixedly connected to the inner side in the heating chamber. According to the crane boom for the crane, heated high-pressure gas is sprayed out through the gas spraying opening in the front end of the first boom section, air can be blown to the cleaning rods fixed to the two sides of the box body and the heating treatment box, the cleaning rods are made to rotate, and dust and sand falling on the second boom section and the third boom section are cleaned; and wet soil can be prevented from adhering to the cleaning rod by blowing out hot air, so that abrasion of dust, grit and the wet soil to a sealing layer at the connecting position of the suspension arm is reduced, and the service life of the sealing layer is prolonged.

    本发明涉及起重臂技术领域,特别涉及一种起重机用起重臂,包括第一臂节,第一臂节的上端后侧固定连接有固定座,固定座的上端固定连接有鼓风机,鼓风机的前端固定连接有加压风管,加压风管的前端固定连接有加热处理箱,加热处理箱的内部后侧开设有加热室,加热室的内部内侧固定连接有电热管。本发明的一种起重机用起重臂,通过第一臂节前端的喷气口喷出加热后的高压气体,可以对着固定在箱体与加热处理箱两侧的清洁杆吹风,使得清洁杆旋转,对滚落在第二臂节与第三臂节上的灰尘沙砾与进行清理,通过吹出热风可以防止潮湿泥土粘在清洁杆上面,从而减轻灰尘沙砾与潮湿泥土对吊臂连接处的密封层的磨损,延长了密封层的使用寿命。
