FIG. 2

The invention relates to lifting devices, namely, devices to an overhead crane for mounting and dismounting.

The chain of the invention is the expansion of functional capabilities by providing for the installation and dismantling of crane gantries.

FIG. 1 shows a device for an overhead crane for mounting and dismounting, plan view; in fig. 2 shows a console, a plan view: in FIG. 3 is a view A of FIG. 2

The device contains a bridge crane 1, on the end beam 2 of which the console 3 is rigidly mounted parallel to this beam. At the free end of the console 3, a horizontal bypass device 4 is installed, comprising two lateral blocks located in the same horizontal plane at a minimum distance from each other. At the free end of the console 3, the hinge 5 is also hinged and can be rotated in the horizontal plane. On the console 3 mounted lever winches 6, the ropes 7 which are connected with the jib 5 so as to ensure the rotation of the jib in the horizontal plane. In addition, an electric winch 8 is mounted on the bridge crane 1. The load carrying rope 9 of which is passed through the said horizontal tap device 4, as well as through block 10. mounted on the free end of the jib 5. At the same time, the end of the load carrying rope 9 is connected to the lifting body (not shown ).

The operation of the device is as follows.

To dismantle the crane girder, the lugs 5 are mounted on the same straight line using lever winches. The sling beam to be dismantled is attached to the rope 9. They dismount the fastening elements of the beam to the building structures. Then turn on the electric winch 8 and lift the beam from the supporting tables of the columns. After that, using one of the lever winches 6 rotate the noose 5 at a given angle in the direction of the center of the bridge crane 1 so. to

0 beam went beyond the dimensions of the tables of columns. Then again include electric winch 8, but in the reverse direction, lowering thereby dismantling the beam. The installation of a new crane girder is carried out in a reverse order.

Claims (1)

Claims An apparatus for a bridge crane for mounting and dismounting, comprising a console mounted on a bridge crane parallel to the crane's end beams and a winch with a rope stored in the console-guided blocks, the free end of which is connected to the load-bearing unit, characterized by. that, in order to extend the functionality by providing installation and dismantling of crane girders of bridge cranes, it is equipped with two lever winches mounted on the console and a jib mounted on the free end of the console with the possibility of turning in the horizontal plane by the indicated lever winches, while the console 5 is mounted on the end beam of the crane, the guide blocks are mounted horizontally on the upper end part of the console, and the block around the free end of the jib is fitted with a load carrying rope.
