Abstract

The invention relates to construction equipment. The purpose of the invention is to improve the accuracy of installation of the cart and simplify its design. A cart for transporting a tower crane contains a frame 1 with traveling wheels, the ends of which are attached to the lower part of the chassis frame 2 behind the mounting position of the transport trolley, hangers 4 mounted on the frame 1 of the trolley, cooperating with guides 3, limiting stops for suspensions 4 and guides blocks 5, which are suspended under the turntable 6 of the crane and bend around the top with guides 3 stored on the control blocks 7. The latter are freely attached to the grippers 8 with stops, by which the blocks 7 are attached to the crane new rails 9. 2 ill.

about u

The invention relates to construction equipment, namely, carts for the transport of tower cranes.

The aim of the invention is to improve the accuracy of the installation of the cart and the impact on the design.:.

FIG. 1 shows a trolley for transporting a tower crane, a general view; in fig. 2 - scheme of stocking two trucks.

A cart for transporting a tower crane contains a frame 1, mounted under the chassis frame 2 of the tower crane, flexible directions, 3 and the end of which are connected to the lower part of the chassis frame 2 behind the installation site of the cart. On the trolley, the suspensions 4 are mounted, with the help of which the trolley is suspended on the guides 3. The guide blocks 5 are suspended under the turntable 6 of the crane using lugs and a hook (not shown) and bend around the flexible guides 3, which are stored on the balancing blocks 7. The latter loosely attached to special claws 8, which blocks 7 are attached to crane rails 9. Restraining stops 10 are mounted on the guides of the carriage on the guides 3. Guides 5 and balancing 7 blocks are pulleys, see they are axled in the holder.

The cart works as follows.

Tensioning the boom hoist (not shown) raises chassis frame 2 relative to the hinges of the front running carriages, while rigid guides 3 tighten as they are fixed to the rails 9. When tensioning the guides 3, the car is lifted and moved along the directions of the SLIEMI 3 to the installation site under the force of gravity. After fixing the cart

stops 10 on it lower the chassis frame 2. The length of the guides 3 depends on the height of the cart and the geometrical location of the points of attachment of the cart to the frame 2 and the suspensions 4 of the cart. The presence of balancing blocks 7 allows the guides to be evenly stretched.

To roll out the trolley from under the chassis frame 2 of the crane, the ends of the guides 3 are fixed to the frame 1 of the trolley and, by lifting the chassis frame 2, pull the guides 3, which pull the trolley from under the chassis frame 2 along the crane runway (FIG. 1 is shown by a dotted line). After that, the chassis frame 2 is lowered onto the rails 9 and the trolley moving device is dismounted.

For the simultaneous movement of two carriages, two loops of the guides 3 are used (Fig. 2).

Claims (1)

Invention Formula A trolley for transporting a crane, containing a frame with traveling wheels and a device for moving it, including suspensions mounted on flexible guides, with the possibility of attaching to the lower part of the suspension frame of the tower crane with their ends, envelopes mentioned guides, characterized in that, in order to increase the accuracy of its installation and simplify the construction, the device for moving the frame of the trolley is equipped with balancing blocks that can be fixed to the crane rails, and the guide blocks are installed with the possibility of mounting under the turntable tower crane.
