Company adjustable jib

The invention relates to an adjustable jib and, more particularly, to a jib which can be adjusted to different lengths of containers in order to set them down for storage or to put them on and remove them from ships and the like. M.

In the transport industry, the use of containers or containers for handling splendor has become established. These Containers are generally gripped by a rectangular-shaped Kanbalken, the clamps or brackets for receiving of the container. This is then transported with a trolley. A crane beam typical for such cases is in U.S. Patent 3,078,115. Jib this one The way they have been used in the past can only hold containers of a single length. If containers are different Must be transported length, the crane beam must be replaced. This costs time and reduces the Efficiency. "

The object of the present invention is thus to create a crane beam with the container of any length without limitation can be taken up or down.

The present invention provides a trolley that runs on overhead runways that are spatially separated from one another horizontal cable drums and drives for these cable drums, with the cable drums and drives on the trolley are mounted on sliding plates, devices for moving the sliding plates on the trolley are provided, ropes vnn hang down each cable drum, a jib hangs on these ropes, this jib one main section and two on the Main section has end sections which can be slid into one another,

and means are provided on the main section for sliding the end sections. Preferably the end sections and the slide plates are operated by hydraulic cylinders. These are acted upon at the same time to the sliding plates and slide the end portions in alignment with one another.

Using the example of the embodiment shown in the drawing the invention will now be further described. In the drawing is:

FIG. 1 shows the trolley lo that runs on running rails 11. The trolley has two spaced apart sliding plates 12 and 13 on. Each sliding plate has a downwardly projecting shoe 14 which runs on rails 15. These rails 15 run on both sides of housing openings 16 and 17 provided in the trolley Io. Sitting on each slide plate 12 and 13 a hydraulic sliding cylinder 18. These have pistons 19 which are connected to one another via a universal joint 2o. the The trolley Io also has guide flanges 21 that are still dependent

on. A cable winch 22 is also located on each slide plate 12 and 13. Each cable winch 22 is driven by a gear 23 driven by a motor 24.

A rope 25, on which the adjustable crane beam hangs, runs from each of the two rope winches 22. This consists of a main section 26 with four parallel rails 27 »28, 29 and 30, which are equidistantly spaced apart, and two end sections 31 and 32. The end section 31 also has two parallel rails 33 and 34. These have the same distance from one another as the rails 27 and 3o and are below these. On each rail 33 and 34 there is an upright shoe 35 'and the * slides along and bears against the rails 27 3o thereto. The rails 27 and 3o have similar downwardly extending shoes 36 which abut the rails 33 and 34, respectively. A nylon sliding surface 37 is provided on each shoe 35 and 36. Likewise, the end section 32 has two rails 38 and 39 which are parallel to one another and which are at the same distance from one another as the rails 28 and 29 and lie below them. Likewise, each rail 38 and 39 has an upright shoe 35 which is identical to the shoes on rails 14 and 34. The rails 28 and 29, however, have downwardly projecting shoes 36 which are identical to the shoes on the rails 27 and 3o. The end section 31 also has a disk carrier 4o which projects vertically upwards and has a disk 41 over which the cable 25 runs. The end portion 32 | similarly has a pulley carrier 42 with a pulley 43, over which a rope 25 also runs. Two cylinders 44 and 45 are attached to the main section 26. The cylinder 44 has a piston 46 which engages the end section 31. In contrast, the cylinder 45 has a piston 47 which engages the end section 32. When the pistons 46 and are actuated, the end sections 31 and 32 are displaced relative to the main section 26. Each end section 31 and 32 also has a busbar 48 for supplying electrical energy. The constructions described in US Pat. No. 2,864,9o7 are suitable for this purpose. The crane beam receives its electrical drive energy from the trolley via a power cable 49 which is wound onto a cable drum 5o. This cable

109833/1385

drum 5o reels the power cable 49 when lowering the crane beam unwinds or rewinds it when the crane beam is lifted.

The construction according to the invention works as follows: The trolley Io is driven over a container to be lifted. At the same time, the cylinder located on the trolley Io will then be 18 and the two cylinders 44 and 45 on the crane beam. They move the winches 22 and the two end sections 31 and 32 so that the container is grasped and lifted can be. The crane beam is then hooked into the container and the container is lifted by the cable winches 25.

Figures 5 and 6 show a second embodiment. In this embodiment, only one slide plate 12a postponed. The sliding plate 12 a runs on wheels 6o and thus dispenses with the sliding shoes, as they are with the sliding plate 12 of the first embodiment can be used. The sliding plate 12a is with a hydraulic piston or a drive motor moved, which acts on the wheels 6o. These run on rails 61 in the direction of a stationary plate 62. The Otherwise, the crane beam and its mode of operation correspond exactly to that of the crane beam of the first embodiment. Even with this one Of course, impellers can be used instead of the sliding plates will.
