increased convenience in operation. The device contains two horizontal traverse 10 with suspensions, including blocks I1, the upper of which is connected with the cable 5 of the lifting mechanism 1, and the lower with a load 4, stocked on blocks 1 1 cable 6, which is fixed at one end on the traverse 10, anchor 18 with a delay 12 for the anchor, a counterweight 9, connected to the other end of the cable 6, the traction mechanism 19 with the traction cable 13. The cable harness 6 allows you to change the contours between the crossbars 10 when the load moves into the building opening under the action of the traction mechanism 19. The tension of the cable 6 is provided by the force of elastic stretching from the side 1 2 and counterweight 9. 1 Cp f-ly, 5 ill.

The invention relates to lifting equipment, in particular to lifting devices for supplying heavy loads to a simple building.

The purpose of the invention is improving the usability.

FIG. 1 shows the scheme of lifting and moving cargo in the building opening / in the plan; in fig. 2 shows section A-A in FIG. 1 (pendants are connected in a contour variable along the length by a traction rope); in fig. 3 shows the node I in FIG. 2} in FIG. 4 shows a section BB in FIG. 3) 15

Fig. 5 shows a section A-A (the suspensions are connected to the largest permanent contour along the length by a traction rope).

The device for lifting and moving loads comprises a load-lifting mechanism 20, for example a crane, with an arrow 2, a load 4 suspended on a hook 3, a cable 5 of a lifting mechanism and a cable 6 connected with the load 4 and a contour varying in length. The device is equipped with a fixed 7 and a movable 8 hangers connected to each other in the circuit / movement by a cable 6, the free end of which is fixed on the moving counter 30 and 9 and having traverses 10 with suspensions including blocks 1 1, a delay 12 for the anchor, cable 13 traction mechanism and removable lifting devices. In addition, the cable 35 is faithful 10 are equipped with full-turning with respect to their longitudinal axis 14 cargo lugs 15-17, for which blocks 11, a tie 12 for an anchor or a cable 40 13 of the traction mechanism and detachable load handling devices are fastened respectively. The fixed suspension 7 is hung on the hook 3 of the load-lifting mechanism 1 and is connected to the anchor 18 by a tie 12, 45

and the mobile suspension 8 is fixed on the load side 4 via a removable lifting device and is connected to the traction mechanism 1 9 by a traction cable 13. 50

The assembled device is hung on the hook 3 of the lifting mechanism. 1, the load 4 is attached to the removable load handling devices, and then rises to the 55 II position with the help of the lifting mechanism 1 to a height that provides the load 4 to the building aperture. The delay 12 for the anchor is connected to the anchor 18, and the traction mechanism is the 19th traction cable 13. After that, the traction mechanism 19 is activated, which pulls the load 4 away, moving it from position II to position III and positioning it over the installation site by increasing the length the contour of movement between the fixed and movable suspensions 7 and 8. At the same time, the load lugs 15-17 of the traverse 10 automatically orient themselves along the lines of action of the loads transferred from the moving load 4 and the traction mechanism 19 through removable load-bearing devices on the load 4 , cable 13 traction mechanism, rollers

11 with the envelope of the cable 6 on the lifting mechanism 1 and the anchor 18 through the cable 5 of the lifting mechanism 1 and the tie 12 for the anchor. Such automatic orientation of the earrings occurs due to their free rotation relative to the axis 14 of the crosspiece 10. The length of the displacement contour is carried out by involving the reserve of the length of the cable 6, on the free end of which a counterweight 9 is fixed. This counterweight is 9 by weight, providing the tension of the cable 6 to hold the load 4 . elevated position, moves along the plane of the platform behind the cord 6, compensating for the change in the length of the displacement contour. The installation of the load 4 in the design position by using the lifting mechanism 1.

In the case of application of the device in which the fixed 7 and movable 8 suspensions are interconnected to the longest moving contour by the Cable 6, and its ends are rigidly connected, the load moves as follows.

The device is assembled and fastened in the same way as described. Then the load 4 with the help of lifting mechanism 1 is lifted from position I to position II, to the maximum height of the building opening. Next pull

12 for the anchor is connected to the anchor 18, and the cable is the 13th traction mechanism 19. After this, the traction mechanism 19 is activated and the load 4 is moved, moving it from position II to position III, while simultaneously with the operation of the traction mechanism 19 the lifting mechanism 1 must lower the hook 3, compensating for the change in movement

load And with a movable suspension 8 by changing the lifting height of the stationary suspension / with a constant length of the bundle of fixed and movable suspensions 7 and 8. At the end of the movement, the load A is located above the installation site, after which by means of a lifting mechanism 1, the load A is set to the design position.

Claims (2)

Claim 1. A device for lifting and moving loads, containing two clips with 15 blocks, the upper one of which is connected with the cable of the lifting mechanism, and the lower one with the load, stocked on the specified clips cable fixed at one end to 20 of one of the clips, anchor and the traction mechanism associated respectively with the upper and lower clips, about t l and The reason is that, in order to improve ease of operation, it is equipped with a counterweight, an anchor tie and two horizontal crossbars with hangers pivotally mounted at one end on the crossheads with the possibility of rotation relative to them in the vertical plane of the bone and with the possibility of hinged connection of the other ends of the suspensions of one the traverse with anchor of the armature, the cable of the lifting mechanism and the upper cage of blocks, and the other traverse with the cable of the traction mechanism ^, the lower clip of the blocks and loads, while the other end of the cable with union of a counterweight. 2.
