Definitions
- the invention relates to a crane, in particular a large mobile crane according to the preamble of the present claim 1.
- Cranes of the aforementioned type essentially consist of a - often mobile - undercarriage or undercarriage, an upper carriage rotatable thereon about a vertical axis and at least one boom which can be pivoted in the vertical plane, at the upper end of which further booms can be articulated.
- various devices are known and also required, as is evident, for example, from DE-PS 29 33 382.
- a crane with the features mentioned in the preamble of claim 1 is known from FR-A-23 88 756.
- the invention has for its object to design a crane of the type mentioned in such a way that it can be produced with lower costs and at least the same load capacity while reducing the set-up time and shortening the set-up times compared to comparable devices at lower costs and yet has greater availability, in particular versatility.
- the solution according to the invention is based on the idea that the overall problems are not primarily met by constructive measures on the undercarriage, but in a fundamentally different superstructure concept.
- the superstructure is divided into at least two parts and its part facing away from the main boom (hereinafter referred to as “swivel part”) can be pivoted in a vertical plane relative to the part connected to the rotary connection (hereinafter referred to as “middle part").
- the invention has an extremely advantageous effect, since assembly for erecting the crane is considerably simplified, since a longer boom foot is now possible due to the lower superstructure weight with the same high load capacity of the undercarriage.
- the new design of the uppercarriage according to the invention still allows the central part to identify or carry a driver's cab on the side facing away from the pivoting part, preferably in the area of the main boom foot, so that the operating personnel need not change significantly.
- the central part is designed as a plate lying flat on the rotary connection and connected to it, over which the pivoting part extends at least partially.
- the dimensions of the plate can correspond to those of the slewing ring. With the same vehicle length, the swivel part can therefore be correspondingly longer and thus more effective in its mode of action and range.
- the swiveling part carries winches and is equipped with a roller head and rope pulleys for a pull-in mechanism
- the particular advantage of the invention is shown, since it achieves that the superstructure for winches and for the counterweight can now also be used as an assembly support with a set of rollers and as a counter jib while saving a second main jib foot.
- Another advantage of this design is that the cylinder (s) pivoting the superstructure or part of it against the horizontal also serves to accommodate the counterweight plates, the pivotable uppercarriage part being, so to speak, the jib of an auxiliary crane that in comparable devices for this set-up work is additionally needed and at least during this set-up time is missing in other work, which also saves set-up times and the desired goal for such large devices, driving at night, complete use during the day, can be achieved.
- the free end of the swivel part is preferably equipped with a counterweight receptacle, which consists of a hydraulic cylinder with a possibility of hooking in at its free end.
- a counterweight receptacle which consists of a hydraulic cylinder with a possibility of hooking in at its free end.
- a further advantageous adaptation of the counterweight effects to the respective use of the crane can be achieved if, according to a further advantageous embodiment, at least one hydraulic cylinder is articulated on the central part, which in the working position - preferably directed essentially horizontally - engages with its free end on the counterweight. This enables a continuous change of the counterweight lever arm.
- the invention provides a swivel connection, preferably a swivel cylinder between the middle part and the swivel part, which are connected via at least one swivel bearing with a preferably horizontal axis running perpendicular to the longitudinal axis of the superstructure.
- a swivel connection between the swivel part and the middle part opens up a variety of advantageous solution options for the structural design of the connection.
- the swivel bearing can be located at the level of the rotary connection, preferably on the side of the central part facing away from the driver's cabin.
- the swivel cylinder should be hinged to the middle part in the region of the upper edge thereof.
- the swivel bearing is arranged on the side of the middle part facing the driver's cab, there is a particularly simple but effective possibility in that the middle part is designed as a simple plate can be, which rests flat on the pivot connection and is connected to it, both the pivot bearing and the articulation point of the pivot cylinder on the middle part are approximately at the height of the pivot connection and the end connected to the pivot part to the driver's cab end of the middle part or the plate-facing pivot cylinder is hinged at its other end to the end of the middle part or the plate facing away from the driver's cab, so that the pivot part extends at least partially in a space-saving manner over the plate.
- the pivot bearing can also be located in the area of the upper edge of the middle part for certain purposes, either on the side of the middle part facing away from the driver's cab or in the middle above the rotary connection, which is readily apparent advantageous variants for introducing the forces, in particular the opposing forces in the superstructure and thus optimal utilization of the slewing ring.
- the swivel cylinder is expediently articulated on the side of the central part facing away from the driver's cab, approximately at the level of the rotary connection.
- the swivel part can be braced as a jib, so to speak, of an auxiliary crane via the pull-in mechanism with the jib foot of the main jib, the jib foot possibly bearing a counterweight. Since the swivel connection between the middle part and the swivel part is infinitely adjustable in their angular position to each other (floating), in cooperation with another feature of the invention, namely the extensibility of the swivel part, a variable adaptation of the crane properties to local conditions with regard to possible building and other conditions spatial obstacles as well as possible with regard to the load differences.
- the uppercarriage is now not only designed for counterweight support by the invention, the uppercarriage can also be used as the main boom for normal crane operation, the main boom being able to remain in the driving position, ie, and the guying of the swivel part provided for crane operation as Boom can be done on the main boom or its foot. This possible application offers particular advantages when working inside buildings where there are only relatively low room heights.
- the swivel part can be bolted in front of the front middle part, that is to say in the direction of view of the driver's cab, in a further embodiment of the invention.
- a heavier telescopic crane boom can also be attached to the rear part, so that the optional use of lattice boom and telescopic booms is possible without the need for several devices, the extraordinary mentioned for all possible uses and structural configurations The advantage of eliminating a separate assembly support and additional accessories, which saves weight, manufacturing costs and time.
- the further proposal of the invention serves to make the superstructure, in particular its pivoting part, extendable.
- This extension can be done in stages, by arranging one or more, preferably differently long, intermediate pieces after the roller set has been bolted between the roller head and the winch part of the swivel part, or also continuously by equipping the swivel part at least over part of its length as a telescopically retractable and extendable carrier .
- a combination of gradual and infinite extensibility is also possible within the scope of the invention.
- the stepless and / or gradual extension of the swivel part should be accompanied by a corresponding vertical extensibility of the counterweight receptacle, for example by means of correspondingly long hydraulic cylinders for suspending the counterweight, which may be equipped with intermediate pieces.
- the pivoting part can consist of a main support and a guy support.
- This solution becomes structurally particularly simple when the guy support lies flat on the main support in the resting or driving position and extends almost over the entire length of the main support and is preferably adapted in outline to the main support.
- the tensioning beam can be pivotally connected at one end to the main beam near its roller head, while its other end is attached to the pivot cylinder. This design results in a particularly stable guying concept without increasing the weight of the superstructure, i.e.
- the uppercarriage which according to the invention is divided into two parts, into a central part and a swivel part, which are connected to one another in an articulated manner and are infinitely adjustable in terms of their longitudinal axes.
- the large crane shown in Fig. 1 consists of a crane chassis 1 with wheels 2, a superstructure arranged according to the invention, which is arranged thereon and which can be pivoted about a vertical axis 4 via a ball or roller rotating connection 3, which consists of a central part 5 and a pivoting part 6.
- a hydraulic swivel cylinder 13 is pivotally attached, with its free piston end in the area of the top edge of the swivel part at a corresponding articulation point 14 attacks such that in the transport situation shown in Fig. 1, the pivot cylinder 13 assumes a horizontal position.
- the swivel part 6 carries the cable winches 15 required for the crane and, at its free end, a roller head 16 with the cable rollers of a pull-in mechanism 17 shown in FIG. 2.
- FIG. 2 the crane is shown in FIG. 1 in the working position, which is essentially achieved in that the pivot cylinder 13 is actuated, ie in the present case is retracted so that the pivot part 6 pivots about the pivot bearing 9 in a vertical plane and thus the longitudinal axes of the two uppercarriage parts, in contrast to the transport position, now run at an angle to one another.
- a hydraulic cylinder 19 is provided for attaching a counterweight 18 to the free end of the swivel part 6, by means of which the counterweight 18 can be moved up and down in the vertical direction.
- the individual plates of the counterweight 18 can be suspended using appropriate ropes 21.
- two further hydraulic cylinders 22 are provided, which are articulated at their base in the area of the pivot bearing 9 and act on the counterweight 18 with their free piston end.
- these hydraulic cylinders 22 not only have the task of stabilization, but also make it possible in a simple and extraordinarily advantageous manner to change the position of the counterweight 18 horizontally, so that the hydraulic cylinders 19 and 22 enable a very sensitive and variably adaptable counterweight positioning depending on the position desired load capacity and the outreaches is possible, since both the height and lever arm of the counterweight 18 can be adjusted optimally and quickly.
- Fig. 2 further shows the lattice boom in a steep inclined position with shots 23 and 24 additionally bolted onto the jib foot, rearward bracing 25 taking place from the retractor 17 to the head of the main boom, via which the load rope 26 to be actuated by the cable winches 15 also runs.
- Fig. 2 also shows that hydraulically laterally and vertically extendable support feet 27 relieve the wheels 2 during heavy work in the working position and ensure a safe and wide ground support.
- the swivel bearing 9 is, as in the previously explained embodiment, on the lower right side of the upper carriage middle part 5, while also in accordance with the previously explained exemplary embodiment of the swivel cylinder 13 with its articulation points in the upper region of the middle part 5 and the swivel part 6. Furthermore, in these embodiments, in accordance with the example according to FIGS.
- an infinitely variable adjustability of the swivel position of the swivel part 6 is possible by appropriately coordinated extension or retraction of the swivel cylinder 13 - of course, several swivel cylinders can also be arranged in parallel and then in each case accordingly with a smaller diameter - the end position is determined on the block position.
- Intermediate rings which can be attached to the piston rod, allow changeable angular positions of the superstructure swivel part, whereby the middle part and swivel part are mechanically locked using the swivel cylinder (s) for the standard load capacity. In the Working position for increased load capacity is not locked, so that the swivel cylinder is (is) in the floating position.
- an extension of the pivoting part is provided to approximately twice its length, wherein after the roller head 16 has been bolted off, an intermediate piece 28 is inserted between it and the rest of the pivoting part 6 and is releasably bolted. At the same time, a corresponding extension rod 29 or the like can be attached to the hydraulic cylinder 19 serving to suspend the counterweight 18.
- an even greater extension of the pivoting part is achieved by bolting in an even longer intermediate piece 31 with a corresponding extension of the counterweight suspension via a correspondingly longer rod 32.
- 5 shows the addition of the two extension options according to FIGS. 3 and 4, so that a very wide rearward outreach for the counterweight 18 can then be achieved.
- the swiveling part 6 is continuously and automatically extended by a push-out device 34 which extends or retracts the telescopic section 33 provided at least over part of the swiveling part 6 at its end. It should be mentioned in this context that there is also the possibility, in the case of the swivel part 6 provided with the telescopic part according to FIG. 6, intermediate pieces 28 and 31 between the roller head 16 and the swivel part 6 in the manner shown in FIGS. 3 to 5 to bolt in.
- the pivot bearing 9 is located laterally at the top right on the central part 5, while the pivot cylinder or cylinders 13 are articulated below at approximately the level of the rotary connection 3.
- the cantilever foot 7 is also mounted on the middle part 5, this articulation point 11 being located approximately at the level of the pivot bearing 9.
- the central part 5 is designed as a flat plate which rests on the rotary connection 3 and is connected to it in a rotationally fixed manner, via which plate is in the transport position (See FIG. 11) the pivot part 6 extends with its articulation area.
- the pivot bearing 9 is located laterally at the bottom left on the middle part 5 and also the pivot point for the pivot cylinder 13 lies on the middle part at approximately the same vertical height as the pivot bearing 9, the pivot cylinder 13 pointing with its other end in the direction of the main boom foot 7 and on the top side is articulated on the swivel part 6. As shown in FIG.
- the uppercarriage concept shown in FIGS. 1 and 2 is used and the swivel part 6 is used as a jib of an auxiliary crane, the foot 7 of the main boom being braced via the retracting mechanism 17 and preferably without Counterweight 35 works, so that the swivel part 6 can now be used, for example, as an auxiliary crane for receiving its counterweight; this can also be carried out with a higher load capacity with counterweight or ballast 35 on the boom foot 7.
- the pivot bearing 9 is in the embodiment of FIGS. 14 and 15 for the main support 6.1 laterally bottom right on the middle part 5 at about the height of the rotary connection 3.
- the or the pivot cylinder 13 is or are arranged on the top and directly with the free end of the guy support connected, which is articulated at its other end near the roller head 16 on the main carrier 6.1.
- a coupling member 36 between the main carrier 6.1 and the guy support 6.2 prevents the deflection of the guy under pressure.
- the main boom foot 7 is mounted on the middle part near the articulation point of the pivot cylinder 13 at 11.
- the pivot bearing 9 in the exemplary embodiment according to FIGS. 16 and 17 lies far outside the region of the rotary connection 3 on the central part 5, which extends relatively far in the direction of its longitudinal axis in comparison to the other exemplary embodiments 17, so that, according to FIG. 17, in the working position for the swivel part, in particular the main support 6.1, there is a vertical position which is advantageous for some applications.
- the counterweight 18 can be placed on a bracket 37 fastened in the region of the pivot bearing 9, as a result of which a stable positioning of the counterweight 18 is guaranteed.
