The invention relates to mounting devices and can be used primarily for mounting gantry cranes.

The purpose of the invention is to simplify the design.

FIG. 1 shows a gantry crane before installation, general view; in fig. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. 2; in fig. 4 - bolt with mounting carriage.

The device for mounting a goat stool contains a tightening device and a rope 2 connected to the winch. The tightening device includes a straightening device 3 and a locking element, which is a bypass unit 4, fixedly mounted on the rail track 5, and the tie made sectional and fixed at one end on the leg 6 of the crane, the other on support 7 of the other leg of the crane. At the same time, a carriage is mounted on the rail track 5, having a frame 8, two support rollers 9 and four stop rollers 10 installed with the possibility of contact with the rail head cap 5. On the frame 8 of the carriage, the ends of the straps 3 are fixed, which have a compensating tension plot in the form of a spring 11. On support 7 a polyspasny block 12 is fastened, through which a rope 2 is routed, which goes to the winch. The bridge 13 of the crane before mounting is placed on a stand 14, and one of the supports is fixed by an emphasis 15.

The installation of the crane is carried out as follows.

The bridge 13 of the crane is placed on a stand 14 (for example, on a rail stand with sleepers), legs 6 are attached to bridge 13. On the track 5, a trolley is mounted, which is tangled with brace 3. Under the support of one of the legs, the stop 15 is attached and 7 opposite legs attached

polypask block 12, through which the rope 2 is thrown, moving to the winch 1. When the winding winch 1 is turned on, the second leg support 6, resting against the stop 15, remains stationary, and the foot 7 leg moves along the rail track 5 and the bridge 3 rises and the bypass unit 4 provide stabilization of the crane position during lifting.

Claims (2)

Invention Formula A device for mounting a gantry crane, comprising, for each pair of legs on a crane rail, a tensioning device, comprising a locking element fixed by a crane rail, and a clamp attached at one end to the crane leg, and connected to said locking element, mounted on the support of the crane is a polyspast block and stored in it, associated with a winch, which is distinguished by the fact that, in order to simplify the construction, the said fixing element is a bypass block, which bends around It is a flexible element of the ROCKET, the second end of the leg support fixed by the carrier carrying the polydisc block is Krkna, with the placement of the bypass block under the other leg of the crane, which carries the support fixed at the time of mounting the crane with the outer leg relative to the foot of the first leg. 2. The device according to claim 1, characterized in that the tie is made sectional, and the device is provided with a frame mounted by means of support and thrust rollers on the track, on the ends of which are oriented along the rail, the ends of adjacent sections of the tie are fixed, at least two of which are associated with a tension spring with the possibility of change; chi the total length of the tie. dzlss rl Yu FIG. 3 5 8 j
