Definitions

  • the present invention relates to a crane with an undercarriage on which a superstructure is rotatably mounted about an upright axis, and a plurality of preferably hydraulic control units for generating crane movements and provided on the superstructure crane motor for driving the control units.
  • the present invention seeks to remedy this situation. It is the object of the invention to provide an improved crane of the type mentioned above, which avoids the disadvantages of the prior art and the latter develops in an advantageous manner. Preferably, for the transport of the crane its weight and possibly its dimensions should be significantly reduced, without delaying the buildability of the crane at the site noticeably.
  • the crane motor provided on the superstructure, which usually can be a powerful diesel engine, disassembled for transport and to transport it separately from the rest of the superstructure.
  • the crane motor is mounted on a superstructure frame part that can be dismounted from the rest of the crane superstructure and transported separately. So far, it has always been assumed that the crane engine must remain on the superstructure in order to be able to drive the control units with the crane motor for the construction of the crane at the construction site and to be able to move the crane accordingly. However, this is surprisingly not necessary contrary to the previous insistence of the experts. Due to the dismountability of the crane motor and its separate transport, the weight of the superstructure can be considerably reduced. In addition, there is a smaller space requirement of the revolving stage.
  • the crane motor is mounted on a winch frame which carries at least one crane winch.
  • This winch frame, together with the crane motor mounted thereon and the at least one crane winch, can be disassembled for transporting from the remaining superstructure of the crane, in particular can be scraped off, so that the winch frame, the crane motor and the at least one crane winch are separate Transport unit, for example, on a suitable truck can be loaded.
  • the arrangement of the crane motor on the demountable winch frame achieved in addition to the weight savings for the transport in particular a reduction in space requirements in the revolving stage itself.
  • the invention is provided in a further development that provided for the basic functions of the crane actuators, which are arranged on the superstructure, connectable by a drive connection with a undercarriage engine and the latter are drivable. It is advantageously not provided that these actuators always, ie in regular crane operation, are driven by the undercarriage engine, but that the actuators are selectively driven by the provided on the uppercar crane engine and the undercarriage motor.
  • all the actuators on the crane superstructure with the exception of the removable winch frame arranged winch-Stellaggregate of the undercarriage engine so to speak are alternatively driven, if the actual crane motor on the superstructure is not yet grown.
  • the control units comprise according to an embodiment of the invention, a plurality of pumps which are connected to a superstructure arranged on the pump transfer gear, which is selectively connectable to the provided on the superstructure crane engine or the undercarriage engine.
  • the pump distributor gearbox may be preceded by a valve device which has a connection for the undercarriage motor and has a connection for the crane engine.
  • the advantageously hydraulic drive connections can optionally be switched through to the crane motor and to the undercarriage motor.
  • the drive connection between the undercarriage engine and the positioning units arranged on the superstructure can advantageously extend through the rotary transmission leadthrough, in particular the slewing ring, between the undercarriage and the superstructure.
  • the crane 1 shown in Figures 1 and 2 comprises an undercarriage 2, which may be formed substantially as a multi-axle truck, and a superstructure 3, which is arranged around an upright pivot axis 4 on the undercarriage 2.
  • FIG. 1 shows, a crane jib 5 is articulated up and down on the superstructure 3 about a lying rocking axis 6.
  • the crane motor 10 designed as a diesel engine is mounted on the winch frame 7.
  • the crane motor 10 is arranged laterally on the winch frame 7 next to the crane winches 8 and 9.
  • the lateral arrangement of the crane motor 10 increases the superstructure length and thus the necessary pivot radius in crane operation.
  • other arrangements of the crane motor 10 on the winch frame 7 are possible in principle.
  • control units on the winch frame 7 include the pumps P5 and P6, which serve to drive the two crane winches 8 and 9.
  • the control units on the non-degradable part of the superstructure 3 include the pump P1, P2, P3 and P4, of which the pump P1 drives a luffing cylinder to raise and lower the crane jib 5, the pump P2 drives a telescoping cylinder for telescoping the crane jib 5 , the pump P3 drives an auxiliary winch 12 and the pump P4 drives the slewing gear for rotating the superstructure 3.
  • Said pump P1 to P4 are connected to a pump distributor gear 13, which is arranged on the uppercarriage 3.
  • all the actuators ie the pumps P1 to P6, are driven by the crane motor 10 to generate the positioning movements of the crane.
  • the pumps P5 and P6 are connected directly to the winch frame 7 with the crane motor 10.
  • said crane motor 10 is connectable to the pump distributor gear 13 to drive the further pumps P1 to P4.
  • the pump distributor gear 13 is connected by a drive connection 15 through the rotary feedthrough between the undercarriage 2 and the uppercarriage 3 with the undercarriage motor 14.
  • the pump distributor gearbox 13 is preceded by a valve device 16, which on the one hand has a valve port A for connection to the undercarriage motor 14 and, on the other hand, a valve port B for connection to the crane motor 10.
  • valve device 16 When the valve device 16 releases the valve port A, the pump distributor gear 13 and thus the pumps P 1 to P 4 are driven by the undercarriage motor 14. On the other hand, if the valve device 16 switches to the valve connection B, the crane motor 10 on the winch frame 7 can drive the pump distributor gear 13 and thus the pumps P1 to P4.
