Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lifting materials and equipment using a loading platform.

[0002]

2. Description of the Related Art There are widely known techniques for lifting and unloading a cargo receiving gantry provided outside a building by using a mobile crane such as a stationary tower crane for construction or a truck crane.

[0003]

However, in the above-mentioned technology, if the operation time of the tower crane is restricted or avoided, it is necessary to separately prepare, for example, a trek crane. There is a problem of cost and time.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lifting device using a simple cargo receiving gantry that does not affect the operation of a tower crane and does not require a moving crane.

[0005]

According to the present invention, there is provided an apparatus for lifting materials and equipment using a loading gantry.
A running rail (3) on which a hoist (4) runs is provided on a plurality of beams (2) protrudingly provided on the upper floor of the building, and the hoist (4) is connected to a material (7) via a wire (5). ), And each floor of the building (1) is provided with a load receiving gantry (8) protruding so as not to overlap in plan.

[0006]

DESCRIPTION OF THE EFFECTS AND EFFECTS Since the present invention is constructed as described above, a lifting machine that travels on the traveling rail provided on the upper floor can move from the cargo handling area provided on the ground to any of the loading receiving platforms that do not overlap in plan. Can selectively lift materials and equipment. In addition, the equipment can be changed from a loading gantry on one floor to a loading gantry on another floor.

[0007] Since a dedicated hoist is used, the hoist for a building such as a tower crane is not affected.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, members having the same functions are denoted by the same reference numerals, and description thereof will not be repeated.

In FIGS. 1 and 2, a traveling rail 3 is attached to a plurality of beams 2 protruding from an upper floor (a roof in the illustrated example) of a building 1, and the traveling rail 3 is a lifting machine. A hoisting machine 4 is provided. The hoisting machine 4 is configured to lift the material 7 with the wire 5 and the suspending wire 6.

A loading gantry 8 is attached to each floor (the second floor 11 to the fourth floor 13 in the illustrated example) outside the building 1, and a tip 8 a of the loading gantry 8 is attached to a floor beam 16 by a rod 9. It is supported and a safety fence 8a is mounted around it.

Reference numeral 10 indicates a ground floor, and reference numeral G indicates the ground.

Therefore, the span 20 on which the loading gantry is not installed is used as a loading place, and the material 7 is lifted by the hoisting machine as shown by a chain line, and the loading gantry 8 on the desired floor (in the illustrated example, the second floor 11) is lifted. What is necessary is just to move by the traveling rail 3 to the installed span, and to unload the load on the loading gantry 8.

[0014] Similarly, it is possible to easily change the materials and equipment from the receiving gantry to another receiving gantry.

[0015]

The present invention has the following advantages because it is configured as described above.

(1) It is possible to easily lift directly from the ground to a loading gantry installed on each floor, and to directly change equipment between each floor.

(2) Since it is a dedicated lifting machine, it does not affect the tower crane and the like, and it is not necessary to separately prepare a truck crane and the like.

(3) There may be only one cargo handling area on the ground.

(4) Therefore, the construction period can be shortened and the cost can be reduced.
