Description

(54) SUSPENDED MULTI-SPAN CRANE

one

This invention relates to lifting machines.

Suspended multi-span cranes are known that contain a supporting metal structure from interconnected sections by hinges, suspended on running trolleys, moving along tracks fixed to the building’s overlap, and movable along rails mounted on the supporting structure, a loading trolley with a lifting mechanism. However, the known suspended multi-span cranes have a significant construction height due to the location of the lifting carriage under the supporting metal structure. In addition, the passage along such cranes for servicing the mechanisms and trolleys is difficult and requires the construction of special transition ladders and platforms under each driving way,

In order to reduce the construction height of the crane, as well as to improve the maintenance of the supporting metalwork, an u-shaped shape was made, on the side walls of which there are mounted driving beams, carrying on the lower floor for the passage of the service personnel, and on the upper side, the trolley guides.

FIG. 1 schematically shows the proposed crane, a general view; on . 2 is a section along A-A in FIG. one.

Sections 1 are interconnected by hinges 2, which allow the sections to rotate in vertical plane and self-adjusting when the cranes pass through sections of the track with different elevations. Meta; crane construction was suspended from the driving track m 3 by means of trolleys 4 and mixed on them along the workshop. Driving beams 5 of the crane are interconnected by flooring 6, and to the top of them they are attached to the right of the 7, along which the load trolley moves. The carriage contains a metal structure 8 with two winches 9 having common ropes. Traverse 11 is equipped with a hook, blocks and a movement mechanism (not shown) with single-edge rollers 1 2.

The proposed crane works as follows

in a way. The interconnected sections 1 by means of the movement mechanism (not shown in the drawing) and the undercarriage 4 move along the driving track m 3 along the span served. The cart is moved perpendicularly to the direction of movement of the crane along the top along the driving beams 5 by means of rollers 12. One or two winches are activated to lift the load, depending on the required speed.

Subject invention

Suspended multi-span crane containing a supporting metal structure made of interconnected shargshrami seki ı suspended on traveling trolleys, moving along paths fixed to the building’s overlap, and movable along rails mounted on the supporting structure, a cargo trolley with a lifting mechanism distinguished by so that, in order to reduce the construction height of the crane and improve its maintenance, the metal construction is made and -shaped, on the side walls of which the driving beams are mounted, carrying It is located on the lower floor for the passage of service personnel, and on the upper floor, the guides of the load carriage.
