The invention relates to engineering machinery, and provides a superlift side pulling device which comprises a superlift mast, the superlift mast comprises a superlift mast bottom section arm, a superlift mast standard section and a superlift mast top section arm which are sequentially arranged from bottom to top, and the superlift side pulling device further comprises a power cross beam and a side pulling cross beam. Power cross beams are arranged on the left side and the right side of the super-lifting mast bottom section arm respectively, power winches are arranged on the power cross beams, the power winches on the two sides are symmetrically arranged on the left side and the right side of the super-lifting mast bottom section arm, and side pulling cross beams are symmetrically arranged on the left side and the right side of the super-lifting mast top section arm respectively. And a side pulling cable led out by the power winch bypasses the side pulling cross beam positioned on the same side of the super-lifting mast and can be connected with the top of a main arm system of the crane so as to play a side pulling role on the main arm system. The side pulling device is used on the crawler crane, and the lifting performance of the crawler crane under the working condition of an ultra-long boom can be improved. The invention further provides a crawler crane.

    本发明涉及工程机械,提供了一种超起侧拉装置,包括超起桅杆,超起桅杆包括从其底部至顶部依次设置的超起桅杆底节臂、超起桅杆标准节和超起桅杆顶节臂,超起侧拉装置还包括动力横梁和侧拉横梁,超起桅杆底节臂的左右两侧分别设置有动力横梁,动力横梁上设置有动力卷扬,两侧动力卷扬对称布置在超起桅杆底节臂的左右两侧,超起桅杆顶节臂的左右两侧分别对称设置有侧拉横梁,动力卷扬引出的侧拉拉索绕过位于超起桅杆相同一侧的侧拉横梁并能够与起重机的主臂系统的顶部连接,以对所述主臂系统起侧拉作用。本发明起侧拉装置用于履带起重机上,能够提升履带起重机在超长臂架工况下的起重性能。本发明还提供了一种履带起重机。
