The invention provides a lifting appliance, a portal trolley and a double-trolley quay crane, and solves the problems that in the prior art, a double-trolley quay crane is large, heavy, high in cost and complex in operation and that the container transfer efficiency is low. The lifting appliance comprises an overturning spin lock device mounted above a lifting appliance body and a container receiving supporting device fixed below the lifting appliance body, wherein a container falling into a cavity is fixed in the lifting appliance by opening the overturning spin lock device and buckling the container receiving supporting device; and the container is fixed through the lifting appliance to enable the lifting appliance to grab the container by buckling the overturning spin lock device and opening the container receiving supporting device. The lifting appliance can directly receive and grab containers transported by other lifting appliances, the containers can be transferred by hands between the lifting appliances, the waiting time and the multi-time grabbing and releasing time of a transfer platform are reduced, and the working efficiency of the lifting appliance is improved.

    本申请提供了一种吊具、门架小车以及双小车岸桥,解决了现有技术中双小车岸桥都比较大比较笨重,成本高,操作复杂;而且集装箱转运效率低的技术问题。本申请实施例提供的吊具,包括安装在所述吊具本体上方的翻转旋锁装置;以及固定在所述吊具本体的下方的接箱支撑装置;通过打开所述翻转旋锁装置以及扣合所述接箱支撑装置,落入所述空腔内的集装箱被固定在所述吊具内;通过扣合所述翻转旋锁装置以及打开所述接箱支撑装置,所述吊具固定所述集装箱以实现所述吊具对所述集装箱的抓取。即该吊具可以直接接住并抓取其他吊具运输的集装箱,实现了吊具之间的手递手传递集装箱,减少等待和中转平台的多次抓放时间,即提高了吊具的工作效率。
