The invention relates to the field of hoisting and transport machinery, namely, devices for evacuating maintenance personnel from a crane in the event of an emergency or de-energizing the crane when it cannot be lowered from the cab, because under it, for example, equipment can be provided.

The purpose of the invention is to increase the usability of the device.

Figure 1 shows a diagram of a crane with a device placed on it for evacuation of service personnel; figure 2 is the same, the view in the plan; on fig.Z - section in figure 1; on | mtg, 4 - Gazraz BB on fig.Z; on. {. ig, 5 ParBez Bb pa figure 2 ;. in Fig.6, the device for the evacuation, obtyp view; 7 shows an evacuation device suspended from a crane service platform; on fig.Z - section GG in figure 2; Fig. 9 shows an evacuation device suspended from a crane shaft.

The device for evacuating the personnel from the crane contains an Ellstich sleeve 1 with a wider upper end 2 to which the ring 3 is attached. The length of the sleeve 1 is equal to the length. Н1-Ш from the floor of the workshop to the floor of the cabin minus size G equal to 0.51 n. The device also has a flexible sleeve 4, made in the form of a funnel, the lower end of which has a diameter d n rigidly attached to the ring 3. The upper end of the sleeve 4 has a diameter

8, larger diameter d. The length of the sleeve 4 is equal to h - the difference between the levels of the location of the crane service area and the cab floor .. This is necessary; c1 height compensation when transferring the device from the cabin to other elements of the crane span, for example, to the service platform (Fig. 1). A ring 5 is attached to the upper end of the sleeve 4. The device is assembled in a bag and placed

in the case. In this case, the ring 3 is located inside the ring 5. The package in the case is located on a crane containing bridge 6, span beams 7, service platform 8 and cabin

9. In the cabin floor there is a hole (hatch) 10 into which the evacuation device is installed. The device can be installed anywhere on the service platform 8,

For this purpose, it has hatches 11, which are closed with hinged lids 12. When installed in a manhole on the service platform,

5 ring 5. In addition, the device can also be installed in any other place on the crane. For this purpose, the ring 5 is provided with a hook 13, which allows the device to be hung on the to-span crane beam 7 (Fig. 9), or a bracket 14 and a hook 15, which allows the device to be hung on the service platform 8 (Fig. 7). To place a device for evacuation

15 between the span beams 7, it is provided with support bars 16.

The device works as follows.

In the event of an emergency, such as a fire, de-energizing the crane, the attendants use one of the following evacuation options, depending on where the crane is located.

25 For evacuation from the crane cabin, a hatch 10 is opened in the floor of the cabin 9. The bag with the sleeve is opened. A ring 3 is installed in the hatch and a sleeve 4 with a large ring 5 is placed

30 on the cabin floor around the hatch. Sleeve 1 is dropped down. Then, the person kicks forward into sleeve 1 through his broad end 2 and down the sleeve to the floor of the workshop.

When evacuating from the crane site, the cover 12 of the hatch 11 selected for lowering is opened. A large ring 5 is installed in the hatch from the bag package. Then the sleeve is dropped down and the person is lowered.

In case there are no hatches in the deck of the crane service site, the bag with sleeves is attached by means of the bracket 14 and the hook 15 on the flexible rod 17 to the board of the flooring and the under-rail 18 (Fig. 7). The sleeves are then dropped downwards and the cnydK is applied over them.

 If it is necessary to descend between the span beams 7, the cantilever fastening of the bag to the beam can be used by means of a hook 13 hooked to the under-rail

55 19 (Fig.9).

Another option can be used, in which strips 16 fit between span beams on their upper deck of the uk3 flooring. A bag with sleeves is placed on the slats. Sleeves 11979844 are dropped down and descend. hMl
