ー上に乗せておくことができる。Lifting devices of the type described above are commonly used in swing tower cranes having a superstructure. The superstructure is supported by a tower, which must be extended by incorporating additional tower sections as the construction progresses. To dismantle a swing tower crane, the superstructure must be lowered and individual tower sections must be removed. Lifting devices of the type mentioned at the outset are well known for installing or removing tower sections. To elevate the superstructure or tower section before installing another tower structure, the lifting frame is mounted on the base of the superstructure, i.e. on the support of the swivel ring supported by ball bearings, or on the tower section to be lifted. Fixed at the lower end, the connection between the superstructure and the next lower tower section or the connection between two tower sections is eliminated. The lifting frame is then raised in steps and the superstructure or detached tower section is raised until a new tower section can be inserted into the lifting frame through the open side of the lifting frame. The tower division is
It can then be connected to the superstructure and / or previously installed tower sections in the usual way. For the ascending operation, the press shoe is lowered to engage the central part of the upper crossbar of the lift web of the tower section, and the lift crossbeam joined to the press shoe is supported on the corner post of the tower section and perpendicular to the crossbar. Make sure that the load is applied only in the direction. Horizontal forces are exerted on the corner posts by the lifting transverse parts. The lifting web of each tower section has an upper transverse bar with a central theory where the upper ends of the two diagonal bars meet, the lower end of said diagonal bar being adjacent to the corner post and pivoting to the end of the next lower transverse bar. I'm wearing it. When the lift frame is raised one step, the support shoes of the support, after some withdrawal of the press, are lowered until they are supported on the side bars of the lifting web, so that the support shoes firmly engage the side bars. The horizontal bars of the tower crane lifting web must once again absorb the vertical force, but the horizontal reaction force, because the transverse beams joined to the supports are supported on the corner posts of the lifting frame. No need. The hydraulic press can be retracted as soon as the lifting shoe engages the lateral bar, so that it can be placed on the next upper lateral bar before the next lifting step.

法を大きくしなければならないということを意味する。Particularly heavy, large and tall towers are produced, for example chimney towers. In order to build such a tower, it is necessary to form an upper platform for passengers. This platform can also support a crane and must be supported on a tower that must be extended as the work progresses. When using conventional lifting devices for such towers, at least the lifting assembly of each tower section must be designed to be of greater strength only to be able to absorb the thrust forces of the tower or lifting device. I have to. this is,
It simply means that the dimensions of each tower assembly have to be increased simply because the tower sections for extending the tower have to be installed in the lifting device.

It is achieved by providing. In a preferred embodiment according to the prior art part of claim 2 there are two hydraulic presses, these presses having a press shoe and two lifting crossbeams spaced between the lifting frames. It is pivotally attached to the bar and is provided with two supports, which are intended to be supported on another transverse bar of the lifting web of the tower section, these supports being provided with supporting crossbeams.

る。The present invention is mainly based on the fact that simply providing a plurality of supports provided with a hydraulic platform and support shoes does not increase the lifting force that can be exerted by the elevating frame. This is because the lifting force must be exerted on the lateral bars of the lifting assembly of the tower section by means of two supporting shoes and two press shoes, one supporting body at two points and the lateral bars with the forces balanced. It is based on the recognition that it is to bring about a static indefinite system so that uniform support is not performed until the deformation of. On the other hand, the force exerted on the press shoe can be hydraulically balanced by connecting the press cylinders and thus the force acting on the support shoe of the support cannot be balanced. These support shoes
Lateral bars located at different heights act on the lifting assembly.

できる。For this reason, the present invention is not solely concerned with providing a plurality of supports with hydraulic presses and support shoes, but in particular with balancing means associated with the support shoes,
It is to balance the thrust force acting on both support shoes. For balancing the thrust forces as described above, use a lifting device with a lifting frame having two hydraulic presses and a support with ends supporting shoes that engage different transverse bars of the lifting web of the tower section. Yes, this can be done without having to oversize the tower section.

Pivotally attached to the lower end of 39, these rockers basically have an isosceles triangular shape with the apex angle pivotally attached to the upper support rods 38, 39. The inner part of the base 42 of the balancing rocker constitutes a support shoe, which is supported on the transverse bar of the lifting web of the tower section 1. The lower support rods 46, 47 are pivotally attached by pivot pins 44, 45 to the outer portions of the two triangular balancing rockers. The support shoe is constituted by the lower ends of the lower support rods 46, 47 and is supported on the lower transverse bar 48 of the lifting web of the tower section.

51 is fixed to the upper support rods 38, 39 and the lower support rods 46, 47 so that the support rod can also be suspended with an inward inclination. As a result, each of the press shoes and each of the support shoes come to a position where they are supported on the transverse bar by the lifting assembly without having to lift them for said purpose. Since the lifting crossbeams and supporting crossbeams are supported on the corner posts of the tower section and lifting frame, only the vertical thrust is exerted on the horizontal bar of the lifting assembly of the tower section and the bending force acting in the horizontal direction is exerted.
