SU397464A1 - METHOD OF INSTALLATION OF TRUCK TROLLEYES OF BRIDGES TYPE CRANES - Google Patents

Description

one

Known methods of assembling truck trolleys of bridge-type cranes, mainly bridge cranes with overhead trolleys and a cantilever arrangement of loading tracks, carried out by lifting the load trolley to the level of the sectioned running tracks, are set to the design position of the crane. the complexity of the installation work.

In order to eliminate this drawback, according to the proposed method, a freight trolley assembled at a lower level is lifted on a site of a temporarily unidentified section of underbog paths, and then displaced in a horizontal direction along the span, then mounted on an upright track.

For lifting and subsequent horizontal displacement of the cargo trolley, it is advisable to use a lifting device mounted directly on the crane span.

FIG. 1 shows a scheme for the implementation of the proposed method; in fig. 2 - bridge loader, front view; FIG. 3 - the same, Hades from the side.

On the span structure / installed in the design position of the bridge loader with the design stsoram.i 2 mount load-lifting device 3 with cargo polyspasts 4 and lifting beams 5, on which set assembled on n 1

the level of the suspended cargo trolley 6 of the bridge type to be installed. The cantilevered underfloor tracks 7 "in section 8 of the superstructure, where the lifting of the cargo trolley is carried out, before lifting

The latter is temporarily not installed. Raised to the level of partitioned undersized railways in section 8, a freight trolley is displaced horizontally along the span to position III. With

When mounting the truck, the truck occupies various positions, for example, I, II and III.

A lifting device mounted directly on the crane span may include supporting rollers 9, transverse beams 10 with cantilever parts and longitudinal beams 11.

The installation of the trolley can be carried out using various lifting means, which ensure its lifting after the crane span is installed in the design position to the level of underbody paths and subsequent displacement in the horizontal direction along the span of the crane until it is installed on the underrun tracks.

After the load trolley has been moved, the cart tracks are secured to the working position of the temporarily unspecified section of the underboard tracks.

Claims (2)

1. Method of installation of rpyaoiBbix trolleys of bridge-type cranes, mainly luster | Outlets for loading cranes with overhead trolleys and a cantilever arrangement of loading tracks, carried out by raising the load trolley to in order to reduce the labor-intensiveness of the installation work, the cargo trolley assembled at the lower level lifts the section of the temporarily undetermined section of the underboard tracks, and then displaces it into the horizon The tallest direction along the flying structure is installed on the undersurface tracks, after which the section is fastened to the working position. 2. A method according to claim 1, characterized in that. for the purpose of lifting and subsequent horizontal displacement of the load trolley, use a lifting device mounted directly on the superstructure the crane.
