DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a stilting frame for the transport of containers provided with standardised corner castings to be engaged by latch bolts, or turn-lock fasteners, wherein the stilting frame includes corner posts, each of which comprises at its upper end a corner casting for a latch bolt of a transhipment equipment, and at its lower end a latch bolt for engaging a respective corner casting of a container arranged underneath, and wherein in at least one upper corner casting a switching member is arranged which may be rotated by the latch bolt of the transhipment equipment and can be operationally connected with the lower latch bolts.
RELATED ART
Adapter frames including such lock-on devices are employed for handling containers, in particular in harbors. The containers used there are frequently of the open-top type, such that the contents of the containers possibly extend above their upper edges, i.e. beyond the four top corner castings thereof. Thus these containers cannot be lifted and transported by using the customary transhipment equipment having only short post stumps at their corners inasmuch as the cargo prevents the transhipment equipment from being lowered by a sufficient amount. For this reason stilting frames are interposed between the container and the transhipment equipment.
Hitherto used stilting frames are mostly manually locked onto or disengaged from the container. Apart from the operator for the transhipment equipment, this requires a second person for manually operating the stilting frame.
In addition there are also fully automatic stilting frames which are, however, as a general rule of a very sophisticated design. Thus a stilting frame or overheight attachment including a storage frame is known e.g. from EP 608 254 A1. Automatically picking up or depositing this stilting frame by means of the transhipment equipment can only be performed in connection with the storage frame. Automated positioning on a container or in combination with a container is, however, not possible as latch hooks of the stilting frame remain locked with the transhipment equipment until actuating elements provided on the storage frame act upon them. This design furthermore requires a specific modification of the transhipment equipment as the locking portions for the latch hooks must additionally be arranged on the transhipment equipment.
DE 43 28 635 C1 discloses a stilting frame equipped with a hydraulic system. Its fully automated operation is achieved through the fact that, apart from the two rotary positions of the latch bolts of the transhipment equipment, three extended positions are provided. To this end, the vertical support columns of the stilting frame are adjustable telescopically. In the respective extended positions, the connections between the transhipment equipment and the stilting frame, or between the stilting frame and the container, respectively, may be established by means of a switching mechanism located inside the support columns. The synchronised hydraulic cylinders provided on each support column and coupled to each other ensure uniform telescopic adjustment of the support columns.
The telescopic design of the support columns does, however, suffer from the essential disadvantage of requiring a synchronising system to avoid tilting and ensure that the container will be picked up accurately. Expenditure in terms of construction is hereby increased substantially.
Moreover the hydraulic synchronising system itself presents more drawbacks with respect to reliability and upkeep of the stilting frame. Under practical circumstances the stilting frames are required to have a long service life and be virtually maintenance-free. For these reasons, maximum simplicity and operational safety are demanded from the construction of the stilting frames.
It is therefore the object of the invention to provide a stilting frame which has a simple construction while permitting fully automatic operation.
According to the invention, this object is attained in that the operationa
