The invention relates to a fire extinguishing and bedding bridge in the form of an extendable ladder with side walls Use in particular on fire-fighting boats, which can be raised from their horizontal booth position and pivoted through 360 ° is and carries a work platform at its upper end.

Fires from ships can mean in the port from land Use of fire engines or, if this is not possible or expedient, from the waterside out by fireboats. The fire fighting attack from the fire boat

can be done directly or indirectly. With direct or Even for individual fire-fighting, hoses are laid from the fireboat to the burning ship in order to deal directly with the To carry fire water from the fire water pumps built into the fire boat to the source of the fire «In the case of indirect fire fighting fire-fighting cannons are used. However, indirect fire fighting is only used when a direct extinguishing attack, for example due to excessive heat radiation or risk of explosion or the like, is not possible, since the effectiveness of this fire fighting method is of course not as good as direct fire fighting and also high water damage cannot be avoided.

Since the hoses carrying the extinguishing agent have to be laid on the burning ship in the event of direct fire fighting, it is inevitable that the fire-fighting teams from the fire-fighting boats, which are very small compared to the overseas ships, use hook ladders or rope ladders on the ship's sides of the burning ships are lowered, and not only Λτ δ .Q / "kVi" IcSnr * Vio os \ nA c * ~ y * v \ esöwt-T * i λ V * ^ c * TX ο λ V ^ τη α + a ^ t oil cr \ i * ί τ αϊΐΑ ^

have porting, borrowings are seldom-thereby under very difficult conditions from the fireboat to the deck of the burning ship, height differences of up to 9 m to overcome «, this difficult translation and transportation has often led to accidents. Furthermore, it is hardly possible to find the one carrying the extinguishing agent To guide hoses in such a way that they are not caught and pushed off by the mutually moving ships or be destroyed.

A retractable fire ladder usually treads do not encounter these difficulties when fighting a fire, because when fighting fires on land, starting from an optimal angle of attack and the required extension length the fire-release ladder the vehicle chassis that supports it, usually correspondingly far from the object to be extinguished can be set up remotely'and no relative movements between the two by'die fire extinguishing and Rescue bridge connected parts, for example between the building to be extinguished and the one carrying the turntable ladder Vehicle chassis, occur during fire fighting on burning ships, especially overseas ships, is usually a very large ship in relation to the fireboat, which is capable of responding to the wave movements of the Water is sluggish or not at all, depending on its strength follows, while the relatively small fire-fighting boat makes strong Sehlinger movements even in a shallow valley executes, which is enlarged by the fire extinguisher bridge that is fixed at the angle of attack Lever arm to an intolerably extensive back and forth movement between the top of the fire ladder and

ropes connected to the bridge have been an option so far A fire extinguishing and rescue bridge in the form of an extendable ladder, like her, was out of the question with conventional mobile turntable ladders is known to be accessible at all for use on fire boats because the relatively small fireboat performs significantly different movements than a large ship, whereby the "putting on" of a ladder is forbidden, while just over such a ladder or, over a catwalk, who "connects the fireboat with the burning ship, not just without great difficulty

could be moved the delete-carrying hoses to the burning ship _s but it would also be possible to create other deleted material or equipment on the burning ship or injured or mountain rigging this Settungsbrücke on! fireboat überzuaetzeno '■'

In special cases, however, a similar problem can also arise with turntable ladders of the conventional type that can be moved on land, namely when they are not used in the conventional way for fighting fires on fixed objects, such as on or in houses, thanks, refineries or the like are used, but for rescuing people from moving waters. As is well known, conventional mobile fire brigade turntables with a working platform arranged at the top of their ladder are used for shipwrecked people who are on a 2 ¹ IoB or the like near a dike or dam or, for example, on a capsized sailing boat in a moving water surface.

The invention set itself, therefore the task. To a fire ·

to create a fire-fighting and rescue bridge, which despite the | divide-like movements of two parts moving relative to one another i with simple and cheap means using known turntable ladders in conventional fire brigade turntable ladders vehicles, the creation of the working platform arranged at the top of the ladder allows and it; furthermore allows not only the extinguishing agent, but also electricity for lighting purposes or as energy for tools to be transported across the bridge and furthermore to ensure particularly safe additional traffic across the bridge, so that its work platform is constantly kept in the working position on the harvarist will _o

Starting from a fire extinguishing and rescue bridge in the form of an extendable ladder with side walls, as is known in conventional fire brigade turntable ladder vehicles, which can be raised from its horizontal rest position and pivoted through 360 ° and carries a work platform at its upper end, this task is achieved and according to the invention thereby for the first time created the possibility of equipping a fireboat with such a ladder bridge in such a way that it can boil in the requirements of meeting the requirements, that the bridge in the case of changes in the relative position caused by pivoting movements between the two parts connected by the bracket, for example between the ship to be extinguished and the fireboat, can be tracked by an automatic control in such a way that the relative position, once set, between the part not supporting the working platform, "for example the burning ship, and the working platform remains almost unchanged _β

Via such a fire-dissolving and Setirong bridge, not only can the extinguishing agents be carried on to the working platform and from there to the burning ship through conventional hoses or pipes, regardless of their position, but fire-fighting materials and equipment can also be carried to the burning ship or the injured or objects to be rescued are salvaged on the fireboat. Further, the application of this bridge is also applied to a relative to Feuerlöschboot moving ship or a moving relative to arranged on the Leiterspitge working platform of a stationary onshore stationary turntable ladder vehicle raft, boat or the like possible, the invention provides an immediate 2Tachführen the rescue bridge or _o, adjusting to the relative movement between fireboat and burning ship or fixed turntable ladder and moving raft or boat, control being possible both from the fireboat or turntable ladder and from the working platform arranged at the head of the rescue bridge _o According to a preferred practical embodiment According to the invention, the laughing control can be designed electro-hydraulically _o

Position makes the rescue bridge steeper or flatter, so is even with frequent and rapidly changing distances between the rescue bridge and the burning ship an immediate tracking of the rescue bridge and thus uninterrupted Connection between fireboat and burning ship ensured, for example »

Unpredictable circumstances can cause the usual swaying between the fire boat and the burning ship so amplified that the automatic tracking of the The bedding bridge is not done quickly enough. It has proven to be very useful for this case that for Erecting and lowering the fire extinguishing and rescue bridge is a hydraulic cylinder that can be acted upon from both sides serves whose pressure side when erecting with a spring-loaded Damping piston and its opposite Side ait is connected to an adjustable relief valve «If the distance between, for example, decreases Ϊ the two ships very quickly, so that the automatic the

possible that, from a certain pressure onwards, the pressure oil could flow out over the oil into the sump Sin retreat the conductor could now only take place against the pressure of the damping piston. Also this possibility can be switched off according to an inventive development in the inlet to the pressure side of the hydraulic cylinder be arranged when erecting a check valve, which is connected to the opposite side of the hydraulic cylinder connected auxiliary cylinder is controllable. The non-return valve causes the piston to retreat excluded, as the oil that has flown in via the damping piston can no longer escape «The rescue bridge will therefore remain in the position that has been shifted by the excessive pressure. When the rescue bridge is laid down the check valve through the auxiliary cylinder connected to the opposite side of the hydraulic cylinder opened, whereby the pressure oil can escape into the oil sump.

In the following, the invention is explained in the form of an embodiment example shown in the drawings Fire-fighting boat described in more detail, purely for example, "Show:

This moves the membrane 72 into the position marked 76 and closes a changeover contact which causes the fire extinguishing and rescue bridge to be erected A lowering of the fire extinguishing and rescue bridge causes the opposite changeover contact »Of course, this automatic tracking of the fire extinguishing and rescue bridge is subject to a time constant so that it cannot follow all too abrupt changes in position between the fire boat and the burning ship 10«. As a result, it is possible that the gas spring 71 is compressed so far that it can no longer yield and that as a result damage or even destruction of the fire extinguishing and rescue bridge occurs. the 3rücke is so committed "Even if no direct mechanical damage to the emergency bridge takes place, a violent change in position can still cause a malfunction in the hydraulic system, causing an unwanted drop in the conductor takes place, which can lead to serious accidents _o to prevent this, is the Hydraulic system for erecting and laying down the fire extinguishing and rescue bridge designed as schematically shown in FIG.
