Definitions
- the invention relates to a crane, preferably a derrick, with a movable Undercarriage, one rotatable on this superstructure, which with a ballast wagon is connected by a drawbar and on the rocking one Boom and a counter jib, to which the ballast wagon is attached, stored are.
- Cranes of this type are known, the weight of the ballast truck and the length the drawbar is designed for the highest load. Should with lighter weights can be lifted, the maneuverability of the Crane be affected in that the drawbar has a length that the For example, obstacles prevent the crane from rotating.
- the object of the invention is therefore to a crane of the type specified create, where the weight of the ballast wagon better to the load to be lifted is adapted and which is easier to maneuver.
- this object is achieved in that the drawbar from one telescopic carrier exists, which is telescopic to a length that the respective Load case corresponds to or is greater than this.
- the counter moment generated by the ballast only needs accordingly to be small, so that the load with a low extension state of the ballast car can be recorded, which is particularly special, for example
- the advantage is if there are obstacles that prevent the ballast carriage from being extended further to make impossible.
- the load during operation extended by rocking the boom can also while the operation of the ballast wagons are driven backwards to thereby to increase the counter moment.
- Such a method of the ballast car can take place when this is supported by its wheels on the ground and easier even if it is in a state of suspension due to the size of the load should.
- the telescopic carrier forming the drawbar is always telescoped so far that the ballast car generates a sufficiently large counter torque. Because of the breakdown of forces of the ballast wagon attached to the counter jib with a rope it follows that basically only a pressure force on the drawbar, however no moment works.
- a particular advantage of the crane according to the invention is that the lever arm, on which the counterballast created by the ballast wagon acts, too can be changed during operation, so that always an adjustment of the Counter-moment to the suspended load or changes in the suspended Load can take place.
- the crane operator can telescope and telescope the beam done by hand or automatically.
- the wheels of the ballast car are controllable.
- a controller is provided which is the wheel axles corresponding to each extension state of the carrier aligns so that they intersect the axis of rotation of the superstructure. This configuration ensures that the ballast wagon when the The upper carriage can also be easily turned when it is not in suspension but is supported on the ground by its wheels.
- the support frame of the ballast car is expediently symmetrical to Cross center plane carried by two sets of wheels.
- These wheelsets can by controllable drives can be rotated about their central vertical axis, namely spinning over 360 ° In this way, wheel sets can be quickly and simply turn to the desired position.
- the wheelsets turn to a position in which they turn below the Chassis frame are parallel to its cross-center line.
- the Support frame in its central plane containing the support with laterally projecting Outrigger is provided.
- These jacks stabilize the ballast wagon during separate transport on the platform of a transport vehicle.
- the jacks also allow for appropriate extension and retraction to pivot the drawbar to a height to the superstructure that a easy coupling to the superstructure is possible.
- the telescopic support expediently consists of tubes, so that it can twist about its longitudinal axis if, for example, the lane of the Chassis of the ballast wagon and the lane of the crane different Have bank slopes.
- the clutches can consist of bolt connections, for example.
- the described invention can be implemented not only in a ballast car, but also, for example, for a crane with a suspended ballast.
- the invention therefore also relates to a crane, preferably a derrick, with a movable one Undercarriage, one rotatable on this superstructure, on which a jib and a counter jib to which a suspended ballast is attached is stored.
- the object is achieved according to the invention in such a crane solved that the suspended ballast opposite by a telescopic carrier the superstructure is supported.
- the carrier is expediently controlled, preferably automatically Control that can be extended and retracted according to the luffing angle of the boom.
- Cranes of the type claimed are usually equipped with overload protection devices, the permissible extension states according to the respective load Payload tables can be read out in the crane control in so-called ROM's are stored. Is an automatic control of the extension states of the the ballast wagon or the suspended ballast extendable and retractable telescopic Carrier provided, the extension states are from the crane control the load capacity tables of the overload protection.
- the derrick seen in Fig. 1 in plan view without jib and counter jib consists of an undercarriage 1 with two crawler tracks and one on this revolving superstructure with a slewing gear 2, on which the boom and counter jib, which are not shown, are pivotally mounted.
- a telescopic Carrier 3 which consists of the shots 4 and 5, a ballast 6 coupled.
- the ballast car 6 consists of a chassis 7, which is symmetrical to it Longitudinal median plane in which the telescopic support 3 is located, two lateral ones Has wheel sets 8, 9, each with six wheels, about vertical axes 10, 11 can be rotated by an endless rotary drive.
- This endless rotary drive can a gear and a meshing with this pinion, which by one Motor, for example hydraulic motor, can be driven.
- the drives of the wheel sets 8, 9 are by a control device by hand or also controllable automatically.
- Fig. 1a shows the position of the wheel sets when driving the crane straight ahead in the Longitudinal center plane telescopic carrier.
- Fig. 1b shows the crane when cornering, in which the wheelsets of the ballast car are controlled to be able to drive in a tight curve radius.
- Fig. 1c shows the crane in a state in which the wheel axles the axis of rotation of the Cut the uppercarriage so that the ballast carriage can also be loaded with the uppercarriage can be rotated.
- Fig. 1d shows the crane when driving straight ahead with offset moving alongside the crane Ballast car.
- the outer telescopic tube 4 as can be seen from FIG. 4, with the chassis 7 of the Ballast car coupled.
- the inner telescopic tube 5 is by a bolt connection 14 can be coupled to the uppercarriage 2.
- the inner telescopic tube 5 is in the outer telescopic tube 4 slidably mounted.
- the displacement of the telescopic tubes relative to each other is carried out by a hydraulic cylinder 15, the cylinder of which the outer telescopic tube 4 closing base plate 16 is fixed.
- a stabilizing rod 20 is provided, which with the articulation of the one piston-cylinder unit on the support frame and the cylinder of the other Piston-cylinder unit 17 diagonally articulated in the manner shown in FIG. 5 connected is.
- FIG. 7 shows a derrick crane without a jib, on its counter jib 30 a suspended ballast 31 is attached via a rope 32.
- the undercarriage and the Superstructures are basically designed in the same way as it is based on the Fig. 1 has been described.
- the suspended ballast 31 is connected to the superstructure 33 of the derrick by one telescopic carrier 34 connected.
- the telescopic carrier 34 is in the 8 evident way by a bolt connection 35 with the superstructure 33rd and by a bolt connection 36 to the suspension of the suspended ballast 31 articulated.
- the telescopic carrier 34 is shown in FIG. 7 Way according to the respective load case or according to the respective Rocking angle of the boom, not shown, can be telescoped or extended, so that in a simple manner by telescoping the Suspended ballast is the counter moment corresponding to the swing angle of the boom can be generated.
