Description

one

The invention relates to hoisting and transport machinery, namely, tower cranes.

 The purpose of the invention is to improve performance.

FIG. 1 shows a crane, in a working position, side view; in fig. 2 - the same, in the installation position on flash ;. 3 shows section A-A in FIG. 2; in fig. 4 - cargo rope stocking; in fig. 5 — node 1 in FIG. 2; in fig. 6 — node II in FIG. 2; figure 7 - view of E in Fig.6.

The tower crane consists of a running frame 1, on which the turntable 2 is installed. On the latter is installed tower 3, load 4 and boom 5 winch. A stand 6 is installed on the side surface of the tower 3 with the possibility of vertical movement, which is simultaneously with the tip. The upper section 7 of the tower 3 has guide rollers 8 in which rack 6 is mounted. On the top section 7, on the one side, there is a pivotally attached boom 9, and on the other, a strut 10, which is in the working position of the crane supported by cable P, and in the installation position - the rope 12, the boom 9 is supported by the boom rope 13, going to the boom winch 5. Cargo rope 14, coming from the cargo winch 4, skirting the block 15 of the spacer 10, block 16, one of the blocks 17 of the upper section 7 of the tower, then on the end; block 18, blocks 19, 20 of cargo hopper 21 and hook holder 22 through block 17 is fixed in the upper part of rack 6. To dock hook holder 22 with boom 9 by means of cargo trolley 21 on clip 22 it is fixed with I through kronshtshynov 23 stop 24.

The end block 18 has a latch 25 position relative to the boom 9 and a buffer element 26. The load carriage 21 also has a buffer element 27 facing the element 26. The boom 9 in the mounting position is supported by a pull 28, and the boom rope 13 is resistant 29. The load the carriage 21 is moved by a winch 30. The post 6 is moved along the tower 3 by a hoist 3, and to the hook of which a rope 32 is attached

7 towers 3.

The installation of the crane is carried out as follows.

Move the trolley 21 with the help of a winch sine 30 to the tower 3 and pull the hook holder 22 to the trolley 21, resting against the stop 24. Using clamp 25, block 18 is detached from the boom, by further wiring the cargo rope 14 onto winch 4, moving it onto the root of the boom and fixing it.

28 are attached to the root part of the boom, the root and head parts of the boom are separated and, by loosening the rope 3, the head of the boom is lowered into a vertical position. The upper part of the crane is detached from the post 6, put the load rope 14 on the winch 4, lift the upper part of the crane and fix it on the post 6, forming a mounting opening. The hook holder 22 is lowered and the mounted section is secured. The mounted section is lifted to the height of the mounting opening and set into it. Join the lower and upper sections with the mounted. The stand 6 is detached from the lower section and, with the help of a hoist 31, is moved
