Definitions

  • the invention relates to a mobile crane, in particular a mobile harbor crane, with an undercarriage, a rotary connection mounted on the undercarriage for a rotatable superstructure, a tower attached to the superstructure, on which a boom that can be pivoted about a horizontal axis is arranged, the boom being attached by means of a Boom and rocker arm articulated on the tower is pivotally held on the superstructure.
  • a so-called pallet loader or unloader is known (DE-38 26 274 A1), which is usually used for a lower load capacity of e.g. 15 tons is designed and can load general cargo, such as pallets, containers and the like.
  • pallet unloaders are correspondingly weakly dimensioned, with a supporting frame being movable on rails, and a boom being articulated on the supporting frame, which can be pivoted upward via tension.
  • a counter jib track for a trolley drive is provided at the joint of the boom, the counter jib always remaining in the horizontal position and being held on the frame of the pallet unloader at most by means of tension.
  • the present invention is based on the mobile crane referred to at the outset, ie on a mobile harbor crane, with an undercarriage, a rotary connection for a rotating superstructure attached to the undercarriage, and a tower attached to the superstructure, on which a jib which can be pivoted about a horizontal axis is arranged is, the boom is pivotable by means of a pair of luffing cylinders arranged on the boom and on the tower and is held on the tower or on the superstructure by means of guy rods or ropes.
  • Such devices are designed for 100 tons and more and dimensioned accordingly.
  • the present invention has for its object to save a separate mobile harbor crane and an additional pallet unloader, i.e. only to use one or the other device.
  • the object is achieved according to the invention in that when the jib is in a horizontal position for operation with a trolley, the trolley track is extended to the end of a horizontally set jib.
  • the advantage of this measure is a second device, i.e. to save a separate mobile harbor crane for an additional pallet unloader, because simple measures now make it possible to use the mobile crane, in particular a mobile harbor crane, as a pallet unloader at the same time.
  • the effort for the design of such a crane is relatively small because only the counter jib and the trolley track are required to create the new device with double function.
  • One embodiment of the invention is that the horizontal position of the boom is held by a load rope.
  • the load rope is advantageously used here in a position which has little or no significance for handling cranes.
  • the counter jib can be pivoted out of the horizontal position or into the horizontal position by means of a retracting mechanism.
  • the retraction is required to return the mobile crane to its other function as a slewing crane, i.e. to move a loading or unloading crane.
  • the trolley when the crane is used as a handling crane, the trolley can be moved into a parking position within the boom linkage and the counter-linkage linkage. Accordingly, a trolley is parked in this tower portal when the device is used as a handling crane.
  • the pull-in mechanism is formed from a hoist with the smallest possible dimensions.
  • Another advantage is that when the crane is used as a handling crane, the counter jib is swung up. The weight of the counter jib partially acts as a counterweight to the main boom.
  • a further development of the invention consists in the fact that the working methods can be controlled from an operating cabin both as a handling crane and as a pallet loader.
  • the mobile crane 1 can be used in particular as a mobile harbor crane and is fixed to its place of use by the method.
  • the mobile crane 1 has an undercarriage 2, a rotary connection 3, which is attached to the undercarriage 2, for a rotatable superstructure 4, and also a tower 5, which is fastened to the superstructure 4 and on which a boom 7 which can be pivoted about a horizontal axis 6 is arranged
  • Boom 7 is pivotally held on the superstructure 4 by means of a rocking cylinder 8 articulated on the boom 7 and on the tower 5.
  • the mobile crane 1 operates here as a port handling crane, the jib 7 being pivoted up by means of the luffing cylinder 8 (or a pair of luffing cylinders) articulated on the tower 5.
  • the jib 7 picks up piece goods 10 from a piece goods load 11 of a transport ship 12 via the load suspension means 9.
  • the piece goods 10 are transferred by swiveling the tower 5 via the rotary connection 3 of the superstructure 4 to a vehicle (not shown) for removal.
  • This handling crane according to FIGS. 1A to 2B additionally has, in addition to the load rope 13 for crane operation, which also serves as a guy rope for the horizontal position of the jib 7.
  • Such load ropes 13 for crane operation are usually not used as guy ropes.
  • FIGS. 2 A and 2 B the handling crane shown in FIG. 1 A is now converted such that when the jib 7 is in a horizontal position for operation with a trolley 16, the trolley track 17 up to the end 18 of a horizontal set counter jib 19 is extended.
  • the counter jib 19 can be pivoted from the horizontal position or into the horizontal position by means of a retracting mechanism 20.
  • the horizontal position of the counter jib 19 is held by means of guy rods or ropes 15 and thus a pull-in mechanism 20 is relieved.
  • the tower 5 is designed as a portal 23 below the boom linkage.
  • the trolley 16 can be moved into a parking position 24 within the jib linkage 22a and the counter jib linkage 22b (FIGS. 2A and 1A).
  • the retractor 20 is formed from a hoist with the smallest possible dimensions.
  • the counter jib 19 is pivoted up as shown in FIG. 1A.
  • the operations of the crane 1 both as a handling crane (FIGS. 1A and 1B) and as a pallet loader (FIGS. 2a and 2b) can be controlled from an operating cabin 25.
