Description

(54) A LANDING DEVICE
(71) We, MASCHINENFABRIK AUGS
BURG-NURNBERG AKTIENGESELLSCHAFT, of
Katzwanger Strasse 101, 8500 Niirnberg, Germany (Fed. Rep.) a German Body Corporate, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to a landing device particularly, but not exclusively for enabling vehicles to drive on and off ferries, floating bridges or the like.
For reasons of economy ferries, floating bridges or the like usually have ramps which are so short that they permit loading and/or unloading or vehicles only from those shores which are shallow or of moderate height. It is common practice to employ so-called gantry runs for high shores. The installation of such gantry runs is however complicated and very time-consuming because the supports must be installed in water so that the installation personnel is often endangered, more particularly in cases of severe currents.
An object of the invention is to provide a
landing device of simply construction, suitable for both relatively high and/or steep shores, which can be readily installed on the shore and removed without the need for installation personnel to be in the water.
The invention provides a landing device comprising a first ramp for resting on a
shore, a second ramp pivotably connected thereto for extending from the shore and having support members pivotably attached thereto, means being provided for pivoting the second ramp relative to the first ramp, the said means comprising masts mounted on opposite sides of the first ramp and struts or ropes provided between the masts and the
second ramp for lowering and raising thereof.
In this way the landing device satisfies all requirements. It can be completely assembled on shore namely in that the first ramp is conveniently placed upon roller boxes to facilitate subsequent sliding, and the second ramp is serially placed thereon and is connected thereto by means of a pivot or pivots. The support members and means for pivoting the second ramp can also be brought into operation with only a few manipulations. Thereafter the entire device with the second ramp is slid over the river, the support members are then pivoted downwardly, and the ramp of the ferry or the like is placed on the second ramp. It is not necessary for personnel to enter the water in order to effect this operation.
Preferably, the first ramp is elongated and is provided with ballast to prevent tilting of the landing device when the second ramp extends in use away from the shore.
Preferably, the support elements are situated beneath the second ramp which has an undersurface shaped so as to accommodate the support members when pivoted theretowards so as to facilitate transportation of the device. To enable the support members to adapt themselves to the appropriate depth of the river bed they are preferably telescopically extensible and are constructed to be locked by known means in any desired position.
Alternatively, the support members are arranged on opposite sides of the second ramps, and are slidable longitudinally in guides pivotably connected to the second ramp.
Preferably, the guides are fixed to cross members pivotably connected to the underside of the second ramp, and the support members may be fixed in different positions in the guides by means of insertion bolts.
This enables the support members to be rigidly constructed.
Preferably, load distribution plates are mounted on the ends of the support members remote from pivotal attachment thereof.
In the light of knowledge of the water currents such load distribution plates should be oval, triangular or round so that slipping on the water bed is substantially prevented.
Preferably, one or more cover plates is pivotably connected to the first ramp for covering the pivotal connection between the ramps.
The landing device may be arranged perpendicularly or at an angle to the shore. In the latter case the first ramp may be provided with intermediate members for increasing the length of the first ramp.
The invention will now be described with reference to embodiments shown by way of example in the accompanying drawings, in which: Fig. 1 is a side view of a landing device according to the invention already installed on a shore;
Fig. 2 is a plan view of the landing device of Fig. 1;
Fig. 3 is a similar view to Fig. 1 of a modified landing device according to the invention;
Fig. 4 is a plan view of the landing device of Fig. 3; and
Fig. 5 is a section taken along the line V-V of Fig. 4.
In Fig. 1 a landing device comprises a first ramp 2 which rests freely on a shore 1 and a second ramp 4 which projects beyond the shore 1. The second ramp 4 is pivotably connected via pivots 3 to the first ramp 2. An upwardly-extending mast 5 is mounted on the first ramp 2 and is anchored by means of a strut 6, which may alternatively be a rope.
In the embodiment shown, a winch 7 is mounted on the mast 5 and carries a rope 8 connected to the outer end of the second ramp 4 so that the ramp 4 may be lowered and raised. Telescopic support members 10 with load-distribution plates 11 are pivotably mounted via pivots 9 at the outer end of the second ramp 2 and may be pivoted in the arrow direction x through more than 90″ to support the second ramp 2 over a river 12.
A cover plate 13 covers the gap formed above the pivots 3 when the second ramp 4 is lowered.
As can be seen from Fig. 2 the support ìnèmbers 9 are normally stored in a raised position beneath the second ramp 4. Each ramp 2 and 4 comprises five longitudinal members 2a, 2b, 2c, 2d, 2e and 4a, 4b, 4c, 4d, 4e respectively, which are coupled together with known means (not shown). The number of these longitudinal members may be increased as desired, depending upon the desired ramp width, in which case further support members 10 may be necessary. The cover plate 13 may also be seen more clearly from Fig. 2.
Zdentical parts in Figs. 3 and 4 have the same reference numerals as those in Figs. 1 and 2. In this case a landing device is shown in the operating position, i.e. the support members 14 bear by means of their load dist-ribution plates 11 on the river bed. Here, ‘the support members 14 are arranged on each side of the second ramp 4, and are constructed as rigid struts which are longitudinally slidable in guiseways 15. As can be seen from
Fig. 3 part of a ferry 16 has a ramp 17 which bears upon the second ramp 4. Further, pails of support members 14 may be provided along the second ramp 4 if necessary.
As can be seen from Fig. 5, the support members 14 together with their load-distribution plates 11 are supported so as to be longitudinally slidable in the guideways 15 and can be locked therein by means of insertion bolts 18. Every pair of oppositelydisposed guideways 15 are rigidly connected to each other by means of a transverse member 19 which in turn is connected by means of pivots 20 to the second ramp 4 arranged thereabove. In this way the support members 14 can always be stood perpendicularly, even if the second ramp 4 slopes steeply.
