Definitions

  • a bridge crane for loading and unloading containers or packing crates into and from a vessel comprises a support structure including a horizontal girder on which one or more carriages are supported for movement each provided with hoisting and propelling devices.
  • a positioning member is also supported for movement along the girder independently of the carriage and is provided with sighting means for determining the position of the positioning member along the girder with respect to the vessel therebelow.
  • a device which may be in the form of an arm for actuating a switch is mounted on the positioning member to halt the carriage at a predetermined distance from the positioning member. In the case where two carriages are provided, one is superimposed on the other and is capable of travelling in a vertical plane therewith and therepast with a load suspended therefrom.
  • the invention relates to a bridge crane in particular for loading and unloading containers or packing crates, the load being unloaded or loaded from and into a vessel respectively by means of at least one carriage adapted to travel over the girder of the bridge crane and provided with hoisting and propelling devices.
  • an arrangement is provided by which the aforesaid period of time is ap preciably shortened and which also permits fully auto matic operation.
  • This arrangement comprises a positioning member adapted to travel over the girder, and provided with sighting means for fixing the position of the positioning member on the girder with respect to one or more points of a vessel, while means are provided to stop a carriage at a predetermined distance from said positioning member.
  • the lowest point of the one carriage with the load suspended therefrom in the topmost position being at a higher elevation than the highest point of the other carriage, so that the carriages are permitted to pass each other in superimposed relationship.
  • the capacity of the crane can be doubled, as it were, since a container can be unloaded from the vessel with one carriage, and simultaneously the other carriage can place a container unloaded from the vessel on a truck on the dock, for instance, while the carriages operate in the same vertical plane, so that in unloading or loading a plurality of loads from or in the same position in the vessel, containers from or in the same stack, for instance, the entire crane need not to be displaced at every turn.
  • the means for stopping a carriage may comprise a projecting bracket on the positioning member, which bracket can cooperate with a switch, or a member operating a switch, on the carriage.
  • the means for stopping a carriage comprises a counting device on each carriage and a counting device in the positioning member with which the respective positions of a carriage and the positioning member on the girder can be determined, and a computer connected to said counting devices, which at a predetermined distance between the carriage and the positioning member produces a control signal in order to stop the carriage.
  • the computer may be connected in such a way with the hoisting device of at least the upper carriage that at a predetermined distance between the two carriages it is ensured that before the carriages pass one another, or lie above one another, the hoisting device of the upper carriage has hoisted the load to its highest position. Owing to these last measures there is thus obtained an automatic safeguard against the danger of impact.
  • the sighting means in the positioning member may be optical means, such as a monitor or a telescope.
  • the positioning member is advantageously formed by a drivers cabin adapted to travel over the girder.
  • the driver positions the cabin, and thus the stopping position of the carriage, with the help of an image of the upper portion of the vessel shown on the monitor in the cabin by means of a Television camera, while the holes of the catches of the containers or of the container guide ways in the vessel may form the points of orientation.
  • the girder may consist of two parts extending in parallel spaced apart relationship, the lower carriage, seen in front view having the shape of a box or trough which, at the end portions of the vertical sides, is supported by the girder, whereas the upper carriage, seen in front view, has the form of a gate which, at the ends of both legs, is supported by the girder.
  • the upper carriage seen in front view, has the form of a gate which, at the ends of both legs, is supported by the girder.
  • the upper carriage may be provided with hoisting means mounted for a rotational movement about a vertical axis, so that a container suspended from the hoisting ropes can be rotated through and be positioned with its largest dimension extending in the longitudinal direction of the girder and the distance between both parts of the girder need only be constructed for accomodating the width of a container.
  • FIG. 1 is a side view of a load handling crane according to the invention with one carriage.
  • FIG. 2 is a side view of a load handling crane according to the invention with two carriages.
  • FIG. 3 is a back view of the load handling crane of FIG. 2 on an enlarged scale.
  • the crane comprises supporting structures I and 2 which are provided with wheels 3 with which the entire crane can travel over dock 4. These supporting structures 1 and 2 support a girder 5 over which a carriage 6 can travel to and fro with the aid of the wheels 7.
  • the carriage 6 is provided with a hoisting device 8 by which the container 10 and/or the yoke 11 can be raised or lowered through the hoisting ropes 9.
  • a positioning member 12 which consists of a drivers cabin adapted to travel over the girder.
  • the member 12 is provided with sighting means in the form of a Television camera positioned at the end of one or more brackets 13 connected with the member 12. Through said camera the driver receives a picture of the upper portion of the vessel 14, so that the driver in the cabin 12 can accurately direct and position the cabin 12 with respect to the openings of the catches of the containers on the vessel.
  • the positioning member 12 has an arm 15 which is adapted to cooperate with a switch on the carriage 6, so that as soon as the switch comes into contact with the arm 15 the carriage will stop.
  • the carriage will always stop at a distance determined by the arm 15 of the positioning member 12, and as the positioning member 12 is accurately located with respect to the vessel, the carriage will also be accurately positioned with respect to the vessel.
  • the driver in the cabin 12 has only to actuate the hoisting device on the carriage 6.
  • the load handling crane shown in FIGS. 2 and 3 comprises supporting structures 21 and 22 which, at their bottom ends, are provided with wheels 23 by which the entire crane can travel over clock 24.
  • These supporting structures 21 and 22 support girder 25 which consists of two parts 26, 27 (see FIG. 3).
  • An upper carriage 28 and a lower carriage 29 are adapted to travel over the parts 26 and 27 of the girder.
  • the upper carriage 28 has a gate-shaped structure which, at the end of its legs is provided with wheels 30, by which the carriage is adapted to travel over the parts of the girder 26 and 27.
  • the carriage 28 is moreover provided with a hoisting device comprising hoisting drurns 31 which are mounted on a platform 32 which is mounted for a rotary movement about a shaft 33 mounted on the carriage 28.
  • the container 35 suspended from the hoisting ropes 34 can be rotated through 90 such that the container can be positioned with its largest dimension in the longitudinal direction of the parts of the girder 26 and 27, so that the distance between the girder parts 26 and 27 need only be constructed to accommodate the width of the container 35.
  • the lower carriage 29 consists of, as seen from the front, a box-like shaped structure which, at the end of the vertical parts, is provided with wheels 36 by which the carriage 29 can travel over the girder parts 26 and 27.
  • the carriage 29 is provided with a hoisting device comprising two hoisting drums 37 by which the container 39 can be raised and lowered through the hoisting ropes 38.
  • a positioning member 40 which comprises a drivers cabin, and which is adapted to travel over the girder parts 26 and 27.
  • the member 40 is provided with sighting means comprising one or more Television cameras at the end of an arm 41 connected with the member 40.
  • the member 40 has arms 42 and 43 which can cooperate with a switch or a similar member on the carriages 28 and 29 respectively.
  • the driver in the cabin 40 receives through the Television camera a view of the upper portion of the vessel 44 and can thus position the mobile cabin 40 with respect to the vessel 44 with the aid of said picture, his bearings being formed by the openings of the catches of the containers on and in the vessel, or the container guide ways in the vessel.
  • the drivers cabin 40 is thus positioned in respect to these orienting points, the projecting arms 42 and 43 having such a length that on engaging the switch on the carriage, whereby said carriage comes to a stop, the carriage is also positioned accurately in respect of said orientating points, so that the driver in the cabin has only to actuate the hoisting device on the carriage, whereupon a container is automatically picked up in the correct manner, or a container is placed in the vessel in the correct manner.
