The invention discloses a self-propelled hydraulic lifting method and belongs to the technical field of gantry cranes. The method is characterized by comprising the following steps of a, overturning afirst gantry leg, a second gantry leg and a girder of the self-propelled hydraulic lifting gantry crane from a horizontal state to a vertical state through a first overturning oil cylinder and a second overturning oil cylinder; b, tying one end of a weight to be lifted to a first rope, tying the other end of the weight to be lifted to a second rope, and respectively upward lifting the first ropethrough contraction of a first lifting oil cylinder and upward lifting the second rope through contraction of a second lifting oil cylinder, thereby completing lifting of the weight to be lifted. Theself-propelled hydraulic lifting method has simple lifting operation and a flexible lifting mode, operation of different working conditions can be met, the lifting stability is good, and the lifting efficiency is high.
本发明公开了一种自行式液压提升方法,属于龙门吊起重技术领域,其特征在于,包括以下步骤:a、将自行式液压提升龙门吊的第一门腿、第二门腿和主梁通过第一翻转油缸和第二翻转油缸从水平状态翻转至竖直状态;b、将待吊装重物的一端系在第一绳索上,待吊装重物的另一端系在第二绳索上,分别通过第一提升油缸收缩向上提升第一绳索和第二提升油缸收缩向上提升第二绳索,完成待吊装重物的吊装。本发明吊装操作简单,吊装方式灵活,能够满足不同工况运行,吊装稳定性好,吊装效率高。
