Description

Electric gantry crane assembly {AN ELECTRIC GANTRY CRANE ASSEMBLY}

The present invention relates to an electric gantry crane assembly, and more particularly, in moving the disassembled boom post unit into a size that can be transported by an operator, the boom post having a high height is moved horizontally to prevent floor height interference and fall. It relates to an electric gantry crane assembly in which the boom post unit can be safely moved in a pivoted state, as well as an electric traction means connected to the boom post unit so that the boom post unit can be easily moved while transporting the transported material with a minimum number of personnel.

In general, semiconductor, LCD, PDP, LED, solar cell, secondary battery production facilities, etc. are installed and used in clean rooms that require strict cleaning conditions.

Conventional forklifts or crane equipment cannot be put into these clean rooms.

In order to bring in or take out various production facilities with large and heavy loads in the clean room with a weight of about several tons to dozens of tons, workers can disassemble and disassemble various production facilities into a small size that can be transported, or move, or conform to the size of the package. A large-sized transport cart with a plurality of wheels installed at the bottom was manufactured, and the transported object was placed on the transport cart, and several personnel pushed the transported object on the transport cart to move it.

However, the conventional method using a transport cart as described above has a problem in that it is necessary to directly manufacture a transport cart having a size suitable for the transported object, since it is possible to safely transport only when a transport cart corresponding to the size of the transported object is provided.

In addition, in the case of heavy loads and large-sized transported goods, a normal forklift or crane is used to load the transported goods into the clean room when they are brought into the clean room. There was a problem in that the worker could not put a large-sized package on the transportation cart, and eventually had to carry it after the dismantling operation in a small size.

The conventional prefabricated gantry crane (Korea Utility Model Registration No. 0466880) separates the main post and the sub post because the height of the main post and the sub post causes interference in the height of the building when moving the separated and disassembled lower moving support. There is a problem that needs to be disassembled, and it takes a lot of time and installation costs are excessive.

In addition, even when there is no interference in the height of the building, there is a risk of a safety accident that may cause a fall due to the center of gravity that is biased according to the height of the main post and the sub post.

In addition, a conventional prefabricated gantry crane equipped with a wheel start unit (Korean Patent No. 1283500) is configured to be easily transported to the wheel start unit, since the gantry crane requires a lot of force in a stopped state.

However, the conventional prefabricated gantry crane equipped with a wheel start unit has a problem that it is very difficult to match the moving balance because two wheel start units must be manually driven at the same time.

In more detail, since the second hinge plate 42 has a long groove H, the position of the second hinge plate 42 is adhered to with the fixing post 20, whereas the first hinge plate 41 has a hinge rod 43 and As the result is raised together, the boom post 30 to which the first hinge plate 41 is coupled is in a state spaced apart from the base frame 10 to a predetermined height.

Thereafter, since the boom post 30 has no rotational interference, the user can easily rotate the boom post 30 horizontally by 180° to mount it on the top of the fixed post 20.

Finally, both sides of the boom post 30 are in an unstable state. As shown in FIG. 7, the support posts 15 are fixed to both upper sides of the base frame 10 to stably support one side and the other side of the boom post 30. Move the boom post unit 100 to the state.

Meanwhile, after moving the boom post unit 100 to a desired location, the boom post units are aligned to a size corresponding to the size of the package.

In addition, a series of processes may be reversed to erect the boom post 30, and the gantry crane assembly 200 may be completed together with the girder 210 on which the hook 211 is formed.

As described above, although it has been described that the boom post unit of the electric gantry crane assembly of the present invention is combined into 2 sets 1 set or 4 sets 1 set, optionally 6 sets 1 set, 8 sets 1 set and Of course, it can be assembled by expanding it together.

In addition, the traction means may be configured by being connected to each of two to the front and rear of the electric gantry crane assembly.
