Definitions

• the invention relates to a device for handling transport units, which has a base frame, two telescopic arms guided telescopically in the base frame, end cross members with locking devices held on the telescopic arms and at least one cross member mounted on the base frame with additional locking devices.
• Such devices are usually referred to as "spreader” and serve as a load handling device for the transport of containers, semi-trailers or other transport units.
• the transport units can be picked up, conveyed further and set down with the help of the spreaders.
• the locking devices generally consist of rotatably mounted locking bolts, so-called twist locks.
• the Locking bolts can, for example, be inserted into corner fittings of containers and, after a corresponding twisting, lead to a positive connection which enables safe handling of the containers.
• the telescopic booms are slidably guided in the area of the base frame, so that in particular handling of 20-foot containers and 40-foot containers is possible.
• the handling of containers with intermediate and oversized sizes is also possible, so that there is typically a working area for container dimensions in the range from 20 feet to 45 feet.
• the load-bearing capacity of the base frame and the telescopic boom are designed for a total weight of the largest manageable containers. This means that there is an unfavorable ratio of device weight to payload when handling small containers. It is therefore also known to enable two small containers to be handled with the aid of a handling device with the aid of additional locking devices.
• the additional locking devices are arranged on a cross member arranged in the middle of the base frame, so that two containers arranged one behind the other can be accommodated.
• a disadvantage of these devices for handling two smaller containers is that the spacing of the containers relative to one another is predetermined by the arrangement of the cross member. For applications in the field of ship technology, this is generally not disadvantageous, since there are firmly defined container distances for all applications. at universal applications, which also include container loading for road traffic or rail transport, the known devices cannot yet meet all requirements.
• the object of the present invention is therefore to construct a device of the type mentioned in the introduction in such a way that the flexibility of use is increased.
• cross members are arranged essentially parallel to one another and displaceably in a longitudinal direction of the base frame and in that one of the cross members is coupled to an end cross member.
• the independently movable crossbeams in combination with the end crossbeams it is possible to position the containers or other transport units along the base frame.
• the coupling of the crossmember to the end crossmember ensures that, despite the displaceability before a connection to the containers to be accommodated, a predetermined distance between the locking devices of the end crossmember and the additional locking devices of the crossmember is maintained in such a way that the corner fittings of the container to be accommodated is possible without additional adjustment work.
• a movable guide of the crossbeams which is functional even under rough operating conditions is provided in that a rail guide with guide profiles and guide rails is provided for the crossbeams.
• the coupling between the cross member and the end cross member has an idling.
• Adapting the spacing of the locking devices to predetermined container dimensions is also supported in that the cross member is supported by a spring against a stop.
• a particularly advantageous embodiment is that the spring is designed as a compression spring.
• An expedient embodiment for the coupling is that the coupling is made telescopically from a spacer tube and a draw tube.
• the draw tube be designed to be variable in length.
• an end stop be arranged in the area of the spacer tube and an end plate in the area of the pull tube, which provide a working distance between the additional locking devices and the locking devices.
• a resilient implementation for the additional locking device is that the additional locking devices on the cross member are designed as load hooks.
• twist locks be arranged so as to be height-adjustable.
• At least one actuating element be arranged in the region of the cross member for positioning the additional locking devices.
• a high degree of flexibility in the laying of the control devices is provided in that the actuating element is designed as a piston-cylinder arrangement.
• FIG. 2 shows a side view of the device with two containers held, 3: a top view according to viewing direction III in FIG. 2,
• FIG. 7 a view corresponding to FIG. 6 without a sectional view of the cross member and the container.
• Fig. 1 shows a container (1) which is held by a handling device designed as a spreader.
• the device has a base frame (2) which extends in the direction of a longitudinal axis (3).
• Telescopic booms (4) which protrude from ends (5, 6) of the base frame (2), are guided in the base frame (2).
• the ends (5,6) are reinforced by borders (7).
• the telescopic arms (4) hold end cross members (8), which are provided with locking devices (9).
• the locking devices (9) are designed as twist locks and can be fitted in corner fittings (10). of the container (1) are introduced. Locking takes place by twisting the twist locks.
• Fig. 2 shows a side view of the arrangement of two cross members (11) in the region of the base frame (2), which are guided displaceably in the longitudinal direction (3).
• a container (1) is held between each of the cross members (11) and one of the end cross members (8).
• the crossbeams (11) each have additional locking devices (12) which can be inserted into the corner fittings (10) of the containers (1).
• the base frame (2) has support elements (13) in the area of its vertical extensions in the vertical direction, which serve for a connection to an industrial truck, a loading bridge or loading cranes.
• extendable guide elements (14) extend parallel to the telescopic arms (4) and improve the Alignment accuracy when telescopic booms (4) are used.
• FIG. 5 shows an enlarged representation of a coupling (15) between the cross member (11) and the end cross member (8). It can also be seen that the cross member (11) engages with a guide profile (16) in a guide rail (17). In the direction of the telescopic boom (4), a range of motion of the guide profile (16) within the guide rail (17) is limited by a stop (18). Dashed lines in FIG. 5 show a positioning of the cross member (11) in the vicinity of the stop (18).
• the additional locking device (12) which is designed as a load hook, is pivotably guided by a cross member (11) on a bolt (19).
• the coupling (15) is designed as a spacer tube (20) in which a draw tube (21) is guided telescopically.
• the spacer tube (20) projects from the cross member (11) through a recess (22) in a guide plate (23).
• the cross member (11) is supported relative to the guide plate (22) by a spring (24).
• the spring (24) is expediently designed as a compression spring.
• the draw tube (21) When the telescopic boom (4) is extended, the draw tube (21) first slides within the distance tube (20). The cross member (11) remains with this Sequence of movement initially due to the tension with the spring (24) in its starting position. After a stop of the end plate (26) on the end stop (25), the pull tube (21) pulls the spacer tube (20) out of the recess (22) and the spring (24) is tensioned.
• the dimensions of the draw tube (21) and the distance tube (20) are chosen such that the locking devices (9) and the additional locking devices (12) are at a distance from one another which corresponds to the containers to be handled.
• draw tube (21) is variable in length.
• the change in length can be carried out, for example, by means of telescoping or a spindle-like adjustment. This embodiment makes it possible to handle transport units that are larger than 20 feet.
• a further embodiment consists of designing the additional locking devices (12) as twist locks.
• the idea here is to provide height adjustment of the twist locks in order to avoid disruptions when the spreader moves apart.
• FIG. 6 shows a cross-sectional representation of the arrangement of the hook-like additional locking device (12) in the region of the cross member (11).
• the additional locking device (12) engages with a hook end (27) in a side recess (28) of the corner fitting (10).
