2. Description of the Related Art FIG. 7 shows an example of a construction lift device conventionally considered in the construction of a high-rise building. In this example, the top floor of a building is jacked up with a core 2 of a building 1 as a fulcrum. A jib crane 4 or an overhanging crane 5 is temporarily installed on the main construction structure 3 so that the material can be transported from the ground 6 to a higher-rise construction floor outside the building 1.

FIG. 8 shows another example of a conventional construction lifting device. In this example, an overhead crane 5 is temporarily installed on the roof of a construction structure 3 and under a beam, and the building 1 is also constructed.
The gate-shaped frame 7 which is in contact with the outer side of the building and whose height is increased by the jack-up sub-joint is temporarily installed. The gate-shaped frame 7 is used as a fulcrum, and the materials are hoisted by the hanging beam 9 that moves up and down by the winch 8 on the ground 6. I am trying to carry the floor up to the construction floor below.

However, in the above-mentioned conventional example shown in FIG. 7, as the building height increases, the lift height of the material by the cranes 4 and 5 increases, and when the suspended load is shaken by wind or the like during the lifting, the swinging of the suspended load occurs. There is a problem that it is difficult to stop and it is difficult to prevent the load from falling when the hoisting rope slips or is cut. In addition, in the above-described conventional example shown in FIG. 8, since the portal frame 7 is used, it is easy to implement measures to prevent sway and fall, but a large number of machines are used for assembling the portal frame 7 and raising it, and There is a problem that it requires time for assembling and disassembling and is dangerous.

Therefore, the present applicant first applied for a new construction lift (apparatus), which is an improvement of the above-mentioned conventional construction lift apparatus, in order to solve the above problems (Japanese Patent Application No. 3-2).

It is possible to prevent the occurrence of horizontal vibration and to suppress horizontal shaking when the suspension beam is moved up and down.
