Problems solved by technology

Its loading and unloading capacity is only half of that of the front trolley. After the current trolley lifts two 40-foot containers or four 20-foot containers or one 40-foot container plus two 20-foot containers to the transfer platform at one time, the rear trolley needs to go through two loading and unloading can only be transferred to the ground transport vehicle, which affects the further improvement of the productivity of the container crane operation

Abstract

The double-bogie container crane capable of hoisting two 40-feet containers simultaneously has the main structure including a gantry frame, a girder, a front bogie and a rear bogie on the gantry frame, tracks on the girder for the front bogie to run on and tracks on the cross beam for the rear bogie to run on, and a container transfer platform set below the cross beam. Each of the front bogie and the rear bogie has one sling system comprising one upper hanger and two slings suspended symmetrically below the upper hanger, so that the front bogie and the rear bogie can hoist two 40-feet containers or other container combination in the same weight. The present invention results in raised hoisting efficiency greatly.

Description

technical field [0001] The invention relates to a loading and unloading machine, in particular to a container crane with double trolleys capable of lifting double 40-foot containers at the same time. Background technique [0002] The strong demand for world container transportation and the continuous growth of container port throughput put forward newer and higher requirements for container handling technology and equipment. Crane productivity requirements. [0003] The container cranes in the prior art are generally equipped with only one trolley. The trolley runs on the rail of the girder and is far away from the ground transport vehicle. Therefore, it is difficult to cooperate with the ground transport vehicle, which affects the working efficiency. In addition, during operation, the loading and unloading of the container corner lock pins is generally completed by the workers on the ground with the container hanging close to the ground by a trolley. The trolley can only e...
