The invention relates to a method for transferring a super-lift counterweight of a crawler crane under a super-lift working condition, and belongs to the technical field of hoisting. The method comprises the following steps that a track is arranged on a ship deck, and the super-lift counterweight is placed on a counterweight trolley sliding along the track; a lifting arm of the crawler crane rotates to a lifting weight placing position in a no-load state, the angle of the super-lift counterweight needing to rotate around the crawler crane is determined, and a driving assembly drives the counterweight trolley to carry the super-lift counterweight to slide along the track; after the super-lift counterweight is in place, the super-lift counterweight and the hoisting weight are hung on the crawler crane, the crawler crane drives the super-lift counterweight and the hoisting weight to rotate to a preset position together, and the driving assembly drives the counterweight trolley to slide to the position under the super-lift counterweight along the track; and the crawler crane puts down the hoisting weight, and the super-lift counterweight is placed on the counterweight trolley. According to the hoisting method under the super-lift working condition, the hoisting transferring operation efficiency under the super-lift working condition can be improved, the labor intensity of constructors is relieved, the moving operation cost is reduced, and the transferring operation safety is improved.
本发明涉及一种超起工况下履带吊超起配重移运方法,属于吊装技术领域,该移运方法包括如下步骤:在船舶甲板上设置一轨道,将超起配重放置于沿轨道滑动的一配重台车上;履带吊的吊臂在空载状态旋转至吊重放置位置,确定超起配重需绕履带吊旋转的角度,通过一驱动组件驱动配重台车载着超起配重沿轨道滑动;超起配重到位后,将超起配重和吊重分别悬挂于履带吊,通过履带吊带动超起配重和吊重一起旋转至预定位置,通过驱动组件驱动配重台车沿轨道滑动至超起配重的正下方;履带吊放下吊重,并将超起配重放置于配重台车上。该超起工况吊装方法,能够提高超起工况吊装移运作业效率,减轻施工人员的劳动强度,降低移运作业成本,提高移运作业安全性。
