Abstract

The present invention is one kind of quayside container crane capable of hoisting three containers simultaneously. The quayside container crane includes one single sling holder with one sling, one double sling holder with two slings, one main hoisting mechanism, one bogie with one pulley block, one double sling holder pulley block and one steel cable winding system. The single sling holder and the double sling holder are connected by means of oil cylinders and one connecting mechanism to constitute one combined sling holder system and have their hoisting mechanisms running independently and synchronously under the control of the electric control device. The quayside container crane has high adaptability and high handling efficiency.

Description

technical field [0001] The invention relates to a container crane, in particular to a quayside crane capable of hoisting three 40-foot containers at one time on the same trolley. Background technique [0002] The development of world trade has led to the rapid development of the container transportation industry, which puts forward newer and higher requirements for the loading and unloading equipment of the container terminal. Improving the efficiency of container loading and unloading has become a common research topic between container terminals and manufacturers. [0003] At present, nearly 4,000 container cranes used in the world can only lift one 40-foot container at a time, and their working efficiency is far from meeting the market demand. For the operation of one berth, in order to improve the operation efficiency of loading and unloading ships, the terminal usually needs to invest 6 to 8 cranes, and more lifting equipment is invested, but the use space of a single ...
