胜利油田的汽车式起重机主要用于在油田钻井,其工位与公路之间地质松软,多为沼泽地带。冬季以外的季节,起重机进、出工作现场极为困难。特别是雨季,地面承载力极低,起重机轮胎常被泥浆淹没,导致起重机难以自行移动,需要使用其他机械拖拽。这对起重机进入和离开沼泽地带的能力,特别是前梁结构强度提出了特殊要求。 Shengli Oilfield truck crane is mainly used for drilling in the oil field, the station and the road between the soft geology, mostly wetlands. Outside the winter season, cranes into and out of the work site is extremely difficult. Especially in the rainy season, the ground carrying capacity is very low, crane tires often flooded mud, resulting in the crane is difficult to move on their own, the need to use other mechanical drag. This poses particular requirements for the crane’s ability to enter and leave the swamp, in particular the strength of the front beam structure.
