Abstract

This invention relates to a lifting and transport machinery. The purpose of the invention is to expand the operational capabilities by increasing the lifting height. The traverse contains a carrier beam 1 with elements 2 for attaching to a lifting mechanism at the ends and a hinge 3 in the middle part. A swivel 4 is connected to the hinge 3. Above the beam 1 with the swivel 4 is located the crossbar 6 of the cargo beam 5, which is made U-shaped with the supports 7, which are provided with gripping bodies in the lower part. The center of mass in the beam 5 is located below the axis of the hinge 3. The load 11 is connected to the gripping bodies. Below the hooks of the lifting mechanisms, only beam 1 and load 11 are located in height, which allows the load 11 to be transferred over the previously located high-mounted structures. 1 hp ff, 2 ill.

The invention relates to a lifting and transport engineering.

The purpose of the invention is to expand the operational capabilities by increasing the lifting height.

FIG. 1 shows the proposed traverse, general view; in fig. 2 shows section A-A in FIG. one.

The proposed crossbar contains a carrier beam 1, which has ends 2 for attachment to lifting mechanisms (not shown) and a hinge 3 in the middle part. Swivel 4 is connected to hinge 3, which is in turn connected to cargo beam 5 ,. made U-shaped with a crossbar 6 and racks 7, while the bar 6 interacts with the swivel 4, located above the carrier beam 1, and the center of mass 8 of the portal is located below the axis of the hinge 3. The gripping bodies 9 interacting with pins 10 mounted equipment 11.t.

Traverse works as follows.

Suspended elements 2 to the two lifting mechanisms of the traverse are supplied by the gripping bodies 9 to the pins 10 of the equipment to be mounted 11 and are connected and further mounted on the equipment 11, in which, due to the fact that the center of mass 8 of the cargo beam 5 and the gripping bodies 9 are below the axis of the hinge 3, the cargo beam 5 with the swivel 4 retains (rotating around the hinge 3) its vertical position

in space (regardless of the inclination of the beam 1 due to non-synchronous operation of the lifting mechanisms) and, if necessary, can be rotated somewhat

together with equipment 11 around its vertical axis (turning relative to swivel 4).

The use of the proposed cross bar allows mounting of vertical telescopic equipment by two lifting mechanisms in height-constrained conditions, which makes it possible to carry out pre-assembly and welding of this equipment at the assembly site in a comfortable and safe environment and reducing installation time.

Claims (2)

1. Traverse, containing a carrier beam with hinge elements on the load-lifting the mechanism and a cargo beam hinged to it with grip bodies at the ends, characterized in that, in order to expand the operational capabilities by increasing the lifting height, the cargo beam is U-shaped with the crossbar located above the supporting beam, and the gripping bodies are located on the ends of racks. 2. Traverse under item 1, characterized in that the cargo beam is made with the center masses located below the axis of its swivel with the carrier beam.
