BALLAST PLATE

Description

[0001] The invention relates to a ballast plate, in particular for a crane.

[0002] When using cranes to lift a specific load, a corresponding counter-torque must be generated. Special ballast weights are provided for this purpose. While the ballast is located at the rear of the slewing platform during crane operation, it is removed from the slewing platform during crane transport and is usually placed and transported on a separate transport vehicle.

[0003] Various forms of ballast weights are known from the prior art. Typically, the ballast weights consist of corresponding ballast plates, such as those known from DE 20 2005 016 815 U1 or DE 20 2008 006 356 U1. Furthermore, document CN104627864A discloses a ballast plate according to the preamble of claim 1.

[0004] However, such ballast slabs can be difficult to handle due to their large dimensions and comparatively high weight. Handling these comparatively heavy and bulky ballast slabs requires complex and time-consuming transport logistics. Not only are appropriately large lifting systems required to handle the ballast slabs, but the transport vehicles must also be of a suitable size.

[0005] The object of the invention is to simplify the transport logistics and handling of ballast plates.

[0006] According to the invention, this object is achieved by the features of claim 1.

[0007] Preferred embodiments emerge from the subclaims following the main claim. Advantageously, the supports and the panels connected to them of two adjacent partial panels are arranged relative to one another in such a way that, in the assembled state, they adjoin one another and can be connected to one another via connecting elements.

[0008] The connection can be advantageously made using connecting elements designed as plug-in bolts or screws secured with nuts. Plug-in bolts can be secured with safety pins to prevent them from falling out of the connecting holes.

[0009] According to a preferred embodiment of the invention, the ballast plate or the respective partial plates are made of concrete. The beams are partially cast into the concrete partial plates. Advantageously, the beams can be U-shaped steel beams.

[0010] According to a particularly preferred embodiment of the invention, the ballast plates are stackable. For this purpose, the respective partial plates can have at least two projections and two recesses of a matching shape, which interlock when several partial plates are stacked. This allows the corresponding partial plates or even the entire plates to be stacked on top of one another in an easy and secure manner when assembled.

[0011] Further features, details, and advantages of the invention are illustrated by an embodiment shown in the drawing. Figure 1: several views of a two-part plate according to the Figure 2 and 3assembled ballast plate according to the embodiment of the present invention shown here; Figure 2: three views of a first partial plate of the ballast plate according to the invention and Figure 3: several views of a second partial plate of the ballast plate according to the invention.

[0012] In Figure 1 A ballast plate 10 is shown, which in the embodiment described here is formed from two partial plates 12 and 14, which are connected to each other via a multi-part connecting element 16. The two partial plates 12 and 14 are mirror-symmetrical.

[0013] Within the scope of the invention, however, more than two partial plates can also be joined together to form a ballast plate. These partial plates can also be asymmetrically shaped.

[0014] The partial plates 12, 14 forming the ballast plate 10 each consist, in a manner known per se, essentially of a preformed concrete part. For easier stacking, they each have two projections 18 on their upper side and two recesses 20 of matching shape on their underside. When stacked, the projections 18 of one partial plate 12 engage the recesses 20 of an overlying partial plate 12, preventing the partial plates from slipping relative to one another. For easier centering, bevels can be arranged on the edges of the projections 18, as shown in the figures.

[0015] The two partial plates 12, 14 are detachably connected to each other via the connecting element 16. The structure and connection mechanism of the connecting element 16 is particularly evident from section AA of the Figure 3 The individual components forming the connecting element 16 are shown in the Figure 2 and 3(there also from sections AA).

[0016] In Figure 2 The first partial plate 12 is shown. Embedded in the concrete body are U-shaped beams 22, 24, which protrude laterally and parallel to the sides. These are screwed to a solid metal plate 30 via screw connections 26, 28. (see section AA of the Figure 2 ).

[0017] In Figure 3 The corresponding second sub-plate 14 is shown. Similarly, two parallel U-shaped beams 32, 34 are embedded in the concrete body. The projecting ends of the beams 32, 34 are also connected to a solid metal plate 36 via a screw connection 38 (see section AA of the Figure 3 ).

[0018] The respective supports 22, 24 on the one hand and 32, 34 on the other hand, as well as the metal plates 30 and 36 connected to them, are arranged in such a way that they come to lie next to each other when the partial plates 12 and 14 are joined together, as shown in section AA of the Figure 1 is recognizable.

[0019] In the U-shaped supports 22, 24 and 32, 34, respectively, in the assembled state, through-holes 40 are provided, arranged next to one another, through which bolts 42 can be inserted to connect the partial plates 12, 14. Split pins 44 can be used to secure the bolts, which can be inserted through transverse holes in the bolts 42 (see section AA in Figure 1 ). The partial plates 12, 14 can be separated again by simply pulling the bolts 42.
