CONCRETE DISTRIBUTOR AND CRANE COMPRISING MASTER}

The present invention relates to a master shared concrete distributor and a crane, and more specifically, a concrete distributor and a crane that can share a master by selectively installing a concrete distributor and a crane for high-rise work in one master, and a master shared a crane. It is about.

In general, a concrete pump car is widely used as a device for transporting concrete to high places when constructing high-rise buildings.

Conventional concrete pump cars are equipped with a placer boom that is folded in multiple stages with a concrete pump, so when constructing a high-rise building, there is an advantage in that it can pump and supply concrete to a high place, while its volume is very large. There are disadvantages in that it takes up a lot of space and expensive operation costs. Especially, the placing boom provided in the above concrete pump car cannot be used in a high-rise building higher than the length of the placing boom because the length of the standing boom is limited. It is pointed out as a disadvantage.

In addition, there is a method of transporting and supplying concrete using a concrete pump, but this has a problem that it is very difficult and time consuming to move the concrete pump itself to the next floor according to the number of floors to be built.

In order to solve this drawback, a concrete distributor that can be installed and used on a building site by combining the placing boom through the master has been proposed.

Concrete distributor according to the prior art is made by the combination of the unit mast and the master is installed on the building site; It is composed of a placing boom detachably coupled to the master. The placement boom includes a rotating body rotatably coupled to the master, a plurality of booms installed on the rotating body and folded to each other, and a weight balance for preventing overturning of the placing boom.

The master may be configured to be mounted in an elevator installation space that is necessarily built in a high-rise building, and at the same time, it may be configured to increase by one floor according to the number of floors of a building to be built in stages.

According to the concrete boom of the prior art described above has the following problems.

When distributing concrete while the booms of the boom are unfolded, a separate weight balance should be used to prevent the boom from being broken or rolled over from the master due to the resistance along the length of the booms and the concrete distribution pressure. There is a disadvantage.

On the other hand, cranes are used to transport various materials in the construction of high-rise buildings.

Conventional crane is built to the height of the building by the combination of the unit mast, there is a hydraulic or the like.

As described above, both concrete distributors and cranes are used together in the construction of concrete buildings, particularly in the construction of high-rise buildings.

However, conventional concrete distributors and cranes have a lot of space limitations because they have to be installed in different places through each master. For example, if a concrete distributor is installed in an elevator space, the crane must be installed elsewhere (perimeter of the building). That is, concrete distributors and cranes are installed through each master, so it is essential to secure space for installation of the master.

The present invention is to solve the above problems, concrete distributors and cranes used in the construction of concrete high-rise buildings and concrete distributors that can be selectively installed in the same place, for example, only one master in the elevator installation space of the building The purpose is to provide a master that the crane is shared with.
