The invention relates to the technical field of hoisting equipment, and provides a superlift device and an operation machine. The superlift device comprises at least one mast, a first guide rope pulley, a second guide rope pulley, a superlift winch and a traction rope, the first end of the mast is connected with the cargo boom, and the first guide rope pulley is arranged at the second end of the mast; the second guide rope pulley is arranged on the cargo boom; the superlift winch is arranged on the mast; the first end of the traction rope is connected with the superlift winch, and the second end of the traction rope is connected with the cargo boom after bypassing the second guide rope pulley and the first guide rope pulley in sequence. According to the superlift device and the operation machine, the positions, located on the two sides of the mast, of the cargo boom can be pulled at the same time through the pulling rope, an original pulling plate structure is omitted, the overall weight of the superlift device and the complexity of the structure of the superlift device are reduced, independent transportation is not needed, and the superlift device and the operation machine are suitable for medium and small tonnage lifting operation machines; and the situation of clamping stagnation is not prone to occurring in variable-amplitude erecting and recycling.

    本发明涉及起重设备技术领域,提供一种超起装置及作业机械。超起装置包括至少一个桅杆、第一导绳滑轮、第二导绳滑轮、超起卷扬和牵引绳,桅杆的第一端连接起重臂,第一导绳滑轮设置于桅杆的第二端;第二导绳滑轮设置于起重臂;超起卷扬设置于桅杆;牵引绳的第一端连接超起卷扬,牵引绳的第二端依次绕过第二导绳滑轮和第一导绳滑轮后连接起重臂。本发明提供的超起装置及作业机械,能够利用牵引绳同时牵引起重臂位于桅杆两侧的位置,取消原有的拉板结构,降低超起装置的整体重量及其结构的复杂程度,不需要单独运输,适用于中小吨位的起重作业机械,且变幅立起和回收不容易出现卡滞的情况。
