Abstract

PROBLEM TO BE SOLVED: To make cranes having performance and ability travel when necessary in a travelling area, in which such performance and ability are not provided, without deteriorating working efficiency even if a carrying equipment is housed not in a two story building which limits the travel range of the cranes but in one plane. SOLUTION: This carrying equipment is to make cranes travel independently of each other in two areas adjacent to each other. A parallel arm 5 is made to travel on two cross rails 4. Two hoists 8, which travel in a material stock area 2, are made to travel on one cross rail 7. This carrying equipment is constituted in such a way that these cross rails 4 and 7 are laid in the same plane and the same direction so that the parallel arm 5 can go into the material stock area 2 utilizing the cross rail 7 of the two hoists 8. As a result, unloading work can be done in each work area effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport facility used for producing large structures such as buildings, ships, bridges and the like.

[0002]

2. Description of the Related Art In a construction site where two work areas are arranged adjacent to each other, for example, a material stock area for storing structural parts and a module assembly area for sequentially transporting and assembling steel materials stored in the material stock area. When producing a large structure such as a bridge, the required crane performance and capacity differ between the material stock area and the module assembly area.

Conventionally, when such cranes having different performances and capacities are used in combination, the construction site described above is operated as a two-story building in the height direction, or a necessary work area is required for each work area. It was common to arrange cranes of high performance and capacity so that they fit within one plane.

[0004]

However, in the former case where the two-story building is operated in the height direction, the support of the building must be enlarged, and depending on the use condition of the crane, the first floor side may be used. There is a problem that the operating range of the crane on the second floor is limited.

[0005] In the latter type, in which a crane having the required performance and capability is arranged for each work area so as to fit within one plane, the crane required in the corresponding area is a crane that is used less frequently. However, since they must be arranged in the corresponding area, there is a problem that the efficiency is reduced both economically and operationally.

[0006] The present invention has been made in view of the above-mentioned problems of the conventional transport equipment when operating an independent crane in two or more adjacent work areas, and the operating range of the crane is described. Even if the two-story building is restricted to a single floor, the crane with the performance and ability not in the work area can be operated in the applicable work area when necessary without deteriorating the work efficiency. The purpose is to provide a transfer facility that can be used.

[0007]

In order to achieve the above-mentioned object, in the transport equipment of the present invention, the crane operating in one of the work areas is a multi-rail crane traveling on a plurality of parallel rails, In addition, the cranes operating in the other work area are a plurality of single-rail cranes traveling on one rail, and the rails of the multi-rail cranes and the rails of the single-rail crane are laid in the same direction on the same plane. The plurality of rail cranes can use the rails of the plurality of single rail cranes to enter the other work area. In this way, even if the crane's operation range is limited to a single plane instead of being two stories in which the operating range of the crane is limited, the work area can be moved to the appropriate work area when necessary without deteriorating the work efficiency. It is possible to operate a crane having performance and ability not in the work area.
