Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulator for crane training, and more particularly to a simulator for training a container crane used on a quay of a container yard or in the same yard.

[0002]

2. Description of the Related Art Conventionally, as a quay-mounted container crane, there is known a container crane having a trolley 52 at a leading end of a main girder and a cab 55 as shown in FIG. That is, FIG.
In the figure, reference numeral 51 denotes (the tip of) a main girder of the container crane, and a trolley 52 is suspended on the main girder 51 so as to be able to traverse. Hoisting rope from above the trolley 52
Spread 53 is supported to ascend and descend via 54. Reference numeral 55 denotes a driver's cab suspended and supported integrally at one end of the traversing trolley 52, and reference numeral 56 denotes a spreader from a ship 57 berthing.
The container when it is landed using 53 is shown. Note that this type of crane is hereinafter referred to as a "trolley driver's seat type crane".

On the other hand, among container cranes used in the yard, there is a type in which an operator's cab 55 is provided independently on the crane main body and only the traversing trolley 52 traverses. This type of crane is hereinafter referred to as an "independent driver's seat type crane". Conventionally, the operation training of these container cranes has been performed using actual container cranes. That is, the method has been carried out by getting into a cab of a container crane provided in a container yard or the like and learning the driving operation from an instructor.

[0004]

By the way, the conventional method of training a container crane as described above has the following problems. Since an unskilled person moves the actual crane, there is a danger of getting on and off the crane, and there is also a danger of collision or damage to the lifting gear during operation training. Since an actual machine crane is used, emergency operation training in the event of a breakdown or the like is not possible. Also, the training location is inconvenient because it is far from ordinary transportation. As shown in FIGS. 4 and 5, in the "trolley type cranes", the spreader 3 must be moved up and down by about 50 m at the maximum. Therefore, the driver must carry out cargo handling by remote control at a long distance while looking substantially right below as indicated by the arrow A, and it takes time to learn the remote control, and it is necessary to use the actual machine crane for long-term training. . Also,
Costs increase, such as securing training space around the facility. An object of the present invention is to solve the conventional problem described above and to provide a simulator for container crane training capable of performing safe and efficient operation training of a container crane.

[0005]
