龙门起重机(与装卸桥)是提高劳动生产率,改善劳动条件的起重装卸设备。与各兄弟单位相比,我们对龙门起重机(与装卸桥)所做的设计与研究工作都很少。近一两年来,曾经有不少单位来我所了解这类设备的设计计算问题。这篇材料是根据来访同志的提问,把日常工作中积累的一点零星材料加以整理,结合本人过去参加设计工作的点滴体会,发表出来供有关同志参考指正。
Gantry cranes (and loading and unloading bridges) are lifting handling equipment that improves labor productivity and improves working conditions. Compared with other fraternal units, we have done very little design and research work on gantry cranes (and handling bridges). In the past year or two, there were quite a few units that came to know the design calculation of such equipment. This material is based on questions from visiting comrades, sorting out a little sporadic materials accumulated in daily work and combining it with my experience in past design work to publish it for reference and correction by the relevant comrades.
