一、起重量的极限在自行式伸缩臂起重机的技术领域中,长期以来所探讨的问题是:这种起重机的起重量极限究竟可达多少?怎样才能进一步提高它的起重量? 现在世界上最大的伸缩臂汽车起重机已达2001吨级的起重量,如西德的哥特瓦尔德(Gottwald)公司的AMK200—103型、克虏伯(Krupp)公司的220 GTM型和美国格柔夫(Grove)公司的TM2500型等。AMK200—103型的参数:幅度4米时的起重量为200吨(稳定性系数75%);主臂最大长度为53米,付臂最大长度为42米;主臂全伸时的最小幅度和最大幅度分别为8米和44米;上车发动机功率为170马力;行驶自重为100吨;6轴底盘,最大轴
First, the limit of the lifting capacity In the technical field of the self-propelled telescopic crane, the long-term question is: How much can the lifting weight limit of this crane be? How can we further increase its lifting capacity? Now the world’s largest The telescopic crane truck crane has a lifting capacity of up to 2001 tons, such as the Gottwald AMK200-103 type in West Germany, the 220 GTM type from Krupp, and the United States Groove (Grove). ) The company’s TM2500 and so on. AMK200-103 parameters: 200 tons (45% stability) when the amplitude is 4 meters; the maximum length of the main arm is 53 meters; the maximum length of the arm is 42 meters; the minimum amplitude when the main arm is fully extended. The maximum range is 8 meters and 44 meters respectively; the engine power of the car is 170 horsepower; the driving weight is 100 tons; the 6-axis chassis, the largest shaft
