These cargo insurance devices have a relatively complex structure.

Traverses of Gauss magneti firm (Italy) are known, in which at the moment of cargo capture the arms are pulled apart, thereby increasing the dimension of the traverse in width, which may impede the dense storage of cargo. (www.gaussmagneti.it).

These cargo-insurance devices have a relatively complex structure, increase the dimensions of the beam and exclude the possibility of using the beam in physically limited, narrow spaces.

Known electromagnetic traverse for overloading the possibility of their lifting under the action of magnetic attraction of workpieces made of iron, or steel, or other magnetic materials, having at least one longitudinal beam with at least one electromagnet located on it as a load gripping device, while on the longitudinal at least one movable carriage of a load-securing device with at least one fur mounted on it is located on or on the side of the beam by winch-type anism for unwinding, respectively reeling in the safety sling and thereby loosening it, respectively tensioning, the carriage of the cargo-insurance device is set in motion by an electromechanical drive. RF patent No. 2293055, IPC В66С 1/04, published on 02/10/2007.

This load-securing device has a relatively complex structure, when the load falls, a slit and rupture of the sling with the sharp edge of the falling load is possible.

The objective of the invention is to increase the reliability and safety in operation by preventing accidental drop in cargo and expanding the technological capabilities of the device by increasing the size range of the transported goods.

The problem is solved due to the fact that in an electromagnetic traverse with a load-securing device, slinged on a hook of a crane containing a load-bearing longitudinal beam with electromagnets mounted on it, the load-insurance device includes transverse beams fixed to the ends of the load-bearing longitudinal beam, in the guides of which are installed with the possibility moving the beams with guide tubes fixed at the ends, while moving the beams in the guides allows you to customize the size s overloaded traverse dimensions under load in width, and guide tubes installed in a tube fixedly secured to the lower end of the pickup having the ability to rotate around its axis in the guide tube and longitudinally displaceable relative thereto.

In addition, a gear wheel is mounted on the upper end of the guide tube, fixed axially by means of half rings and rotatable relative to the guide tube, meshed with the gear of the drive unit.

In addition, in the upper part of the pipe with a fixed pickup, one or more longitudinal grooves are made in which the protruding ends of the pins are located.

In addition, an external thread is made in the upper part of the pipe with a fixed pickup and a nut is installed, which ensures adjustment of the pipe position in height.

In addition, at the upper end of each pipe with a fixed pickup, a signal flag is fixed, the direction of which coincides with the pickup direction.

The invention is illustrated by drawings.

The electromagnetic traverse contains a supporting longitudinal beam 1 with electromagnets 2 mounted on it, which slings 3 are hung on the hook 4 of the crane. The cargo insurance device 5 includes transverse beams 6 fixed on the ends of the supporting longitudinal beam 1, having guides 7 located on both sides, two on each side of the transverse beams, holes are made between the guides 7, the beams 8 are located in the guides 7, which can be moved in the guides , while the movement of the beams 8 in the guides 7 allows you to adjust the dimensions of the beam to the dimensions of the loaded cargo in width, when setting a given size, they are fixed with a bolt connection from holes, and at the end of each beam 8, a guide tube 9 is fixedly fixed, at the upper end of which a gear wheel 10 is mounted, fixed axially by means of half rings 11 and being able to rotate relative to the guide tube 9, engaged with the gear 12 of the drive unit 13. B each guide pipe 9 has a pipe 14, which can rotate around its axis in the guide pipe 9 and longitudinal movement relative to it, with a fixed catch 15 at the lower end. One or more longitudinal grooves 16 are made in the upper part of the pipe 14, and pins 17 are installed in the hub of the gear wheel 10 so that their protruding ends are located in the longitudinal grooves 16 of the pipe 14. An external thread is made in the upper part of the pipe 14 and a nut 18 is installed, leaning on the end face of the hub of the gear wheel 10 and providing the adjustment of the position of the pipe 14 with pickup 15 in height. At the upper end of each pipe 14, a signal flag 19 is fixed, the direction of which coincides with the direction of pickup 15, while the position of the signal flags indicates to the crane operator about the open or closed position of the pickups 15.

The work of the electromagnetic traverse with a cargo insurance device is as follows.

The nut 18 is installed pipe 14 with pickup 15 under the size of the loaded goods in thickness.

In the initial position, the beams 8 are installed in the guides 7 so that the gap between the side surface of the load and the guide tubes 9 is minimal, when setting a given size they are fixed with a bolt connection, the grips 15 are oriented along the longitudinal beam of the traverse.

The electromagnetic beam lowers onto the overloaded load until the ends of the electromagnets touch the surface of the load. In the case when the load lies directly on the surface, the grips 15 of the pipe 14 are supported on the surface, the pipes 14 are moved upward in the guide pipes 9, the pin 17 thus slides in the grooves 16 of the pipe 14. The load is captured. The load is raised above the surface by 200 ... 300 mm.

The drive units 13 are turned on, the gear 12 and the gear wheel 10 are turned, acting through the pins 17 on the grooves 16 of the pipes 14, the pipes 14 are turned so that their grips 15 are turned 90 ° and take up a position under the load.

Now, when the power supply of the electromagnets is lost, the load will rely on pickups 15 and they will be kept from further falling. Then the traverse with the load is moved to the place of unloading and lowered to a height of 200 ... 300 mm above the level of the storage surface. The drive units 13, through the gears 10, acting through the pins 17 on the grooves 16 of the pipes 14, turn the pipes 14 so that their grips 15 are turned 90 ° and out of the load.

In the proposed design, the cargo insurance device is made in the form of rotary levers, due to which the gap between the stacks of goods is less, the storage density is greater.
