Problems solved by technology

This kind of operation process has the following disadvantages: if there is no collection truck coming, it must wait for the collection truck to arrive, resulting in waiting time; the time of the trolley in the full-load and empty-load travel is not fully utilized during the entire operation process, resulting in low efficiency; If it is a crane in the form of a double-box spreader, it requires high operating skills of the driver, and it is difficult to work at heights with two boxes at the same time, and when it is lowered into the collection truck, it requires high requirements on the parking position of the collection truck and the driver's operation. caused the waiting time when adjusting

Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] Traditional container cranes generally use a single trolley operation method, that is, after the main trolley lifts the container from the container ship, it runs along the rail of the crane girder to the top of the collection truck, and then lowers the container to the collection truck. In addition to the road return, there is still waiting time for the main car caused by the absence of the collection truck. The longer reciprocating stroke of the main trolley and the waiting time caused by the failure of the truck to arrive reduce the operating efficiency of the crane.

[0023] Such as figure 1 As shown, the container crane according to the embodiment of the present invention includes a cra...

Abstract

The invention provides a container crane. The container crane comprises a crane girder (3), a main carriage (1), a main carriage lifting appliance (2), a support pillar (4) and a lifting platform (5), wherein the main carriage (1) is arranged on the crane girder (3) and can move along the crane girder (3); the main carriage lifting appliance (2) is arranged below the main carriage (1) and can move along with the main carriage (1); and the lifting platform (5) is arranged at the downstream of the main carriage (1) in the container unloading stroke in a liftable manner, and is used for lifting the to-be-unloaded container. The container crane provided by the invention can be used for well eliminating the generation of waiting time for a lorry, can be easily used for the improvement on old equipment, has greatly increased operation efficiency, and causes no increase in the cost.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a container crane. Background technique [0002] During the operation of the existing quayside container cranes (hereinafter referred to as quayside cranes), with the continuous development of large-scale ships, the requirements for loading and unloading efficiency of quayside cranes are getting higher and higher. Due to the limitation of wheel pressure, it is impossible to make the quay crane infinitely large, and it is limited by the driver's operating comfort, which also makes it impossible to increase the working speed of the quay crane mechanism infinitely. Therefore, we must start from the loading and unloading method and the container crane. Start with its own structure, and strive to find new loading and unloading techniques and methods. [0003] The traditional container crane is generally in the form of single trolley and single spreader (or double container spreader). Its operat...
