The invention relates to the field of lifting and transport machinery, but rather to the extension outriggers, mainly hydraulic craniomandibular installations placed on the chassis of the vehicle, providing resistance against rollover accide the support-rotating devices craniomandibular installations, cranes and various specialized lifting vehicles both domestic and foreign developments (see, for example, ABT. mon. SU N 370160, M. class. B 66 C 23/88, from 15.11.73,; bids N 1465289, MKI B 60 S 9/10 from 02.03.77,, 1467128, MKI B 60 S 9/10 from 16.03.77,, 1496291, MKI B 60 S 9/00, 9/12, 9/22 from 30.12.97, the UK; bids N 58-44495, MKI B 60 S 9/12 from 04.10.83,, 1-195162, B 60 S 9/12, B 66 C 23/78 from 07.08.89, Japan, and others).

In most of these analogues remote outriggers hinged or rigidly fixed at the ends of the retractable from the body frame to the Foundation beams. When this extension beams (removal outriggers) is carried out usually by means of specially provided for this cylinder.

However, many of them are complex in design and have a large mass. Moreover, because of the presence of Autonomous drive movement of the beams on the basis of the cylinders in such a remote outriggers requires additional hydraulic control channels. But, despite this, for many lifting transport vehicles, primarily heavy class used in the above analogues technical solutions in General justified.

For craniomandibular installations easy and in some cases ivalsa removal outriggers, virtually no, because the extension beams attached to them outriggers can be implemented manually. At the same time to provide normalized values attached to the manual effort required to nominate beams, in some cases, take special measures, for example, associated with relief of moving parts, reducing friction in the movable joints, etc.

In addition, construction of the extension of the outriggers of this kind due to the nature of their execution, as a rule, provide for appropriate mechanisms commit nominated beams in the extreme positions.

However, even taking into account these peculiarities of such external outriggers much simpler in design and cheaper in terms of value, compared with the known above counterparts.

From among the known analogues of the proposed technical solution closest (prototype) can serve as a remote support (outrigger) craniomandibular installation ISS-4032 development CJSC "BACM" (, Balashikha-1, Moscow region), the construction of which is given in the Manual for operators on the safe operation of cranes", N. A. Shishkov, M., NGOs MBT, 1995 (BBK 32.816 N P, UDC[621.856.8-5:658.382.3]: 658.386.06), p. Oh posted by manually retractable beam mounted on it with an outrigger, and located on the side wall of the stationary beams off the transom clamp-type locking retractable beams in the extreme positions.

The clamp is equipped with mechanisms forcible withdrawal of the bolt from mating with holes in the side wall of the sliding beams, for example, lever-wedge-type locking it in this position and the reverse input in them when translating the outriggers from one position to another and Vice versa.

To translate the extension of the outrigger from the transport position into the working position in the prototype first manually turn the lock lever in the circumferential direction.

When turning the lever is kinematically interacting with an inclined bevel housing latch and overcoming the resistance of the spring force displays rigidly associated bolt from the corresponding openings in the side wall of the sliding beams. After the withdrawal of the bolt from engagement with the sliding beam it separat in this position by setting the lever on a flat supporting-the installation space of the housing of the latch.

Then by hand a little bit pull themselves retractable beam from the cavity of the base frame and again through corresponding rotation manually lead given ground bolt under the action of the spring instantly goes back all the way to the wall of the sliding beams. And only then finally pull retractable beam from the cavity of the base frame in the last (working) position. When nominating a beam bolt is in constant contact with its wall and in the final position, as just another hole in it at head with it automatically drops into it and securely stoparic beam in the extreme extended position.

After that, the outrigger is transferred into the working position, providing stability to the lifting of the vehicle against tipping.

After handling the outrigger transferred to the original position, and manually manipulating accordingly transom clamp, return the movable beam in the transport position, where she is now discussed above.

The shortcoming of the considered extension of the outrigger is the complexity of his service during the transfer from the transport position into the working position, and Vice versa, due to the need of manual control locking latch when all related work transitions (operations).

The present invention is the improved performance of the inventive remote Aurora retractable beam.
