Definitions

  • the invention relates to a load management on a mobile harbor crane for the combined Container and bulk goods handling, especially on a harbor crane with an am Tower articulated luffing jib, at the free end of which is used for loading and unloading Load suspension devices provided by ships are interchangeably attached.
  • the handling capacity of a mobile harbor crane depends, among other things, on the Pendulum movement that carries the load during transportation.
  • the pendulum length of a conventional luffing crane is inversely proportional to the jib radius, i.e. the minimum pendulum length is at maximum boom radius and maximum pendulum length with minimum boom outreach.
  • the problem of disadvantageous pendulum movement arises in particular when with strong luffing movements of the crane boom between maximum and minimum Boom radius must be worked. Pendulum movements of the load that are too strong Avoid crane operators when luffing the jib by reducing the Rocking speed. This leads to a strong limitation of the Handling performance.
  • the object of the present invention is based on the described Problems and disadvantages of the prior art, a load management on one Mobile harbor crane, especially one with a luffing jib articulated on a tower so that the pendulum length between Load guidance and load are as small as possible with all boom inclinations.
  • the invention provides that the hoisting ropes for the Load handling devices from the lifting devices arranged at the base of the crane Deflection rollers arranged in the area of the tower tip run to the jib tip and after triple reeving between the jib tip and the tower tip Below the luffing jib tip, large dimensioned pulleys are attached to the Lift frame of the load handler guided and fastened there, the Cable pulleys coaxial at the projecting end of one in the front half of the Luffing jib articulated handlebars are stored and using the Kinematic arrangement of the handlebars on the luffing jib on a approximately horizontal path are movable.
  • the cable deflection rollers are preferably fastened by one in their center Holding rope held, the over arranged on the luffing jib pulleys after also triple reeving into the area of the spire and there is attached.
  • the load path on the load handler also causes the middle of the rope pulley led what the further stabilization of the system and thus the prevention of Load pendulum movement serves.
  • Most of the dead weight of the load control works according to the intended arrangement of the tether as a tensile force caused by the Multiple friction of the tether prevents the resulting frictional forces.
  • the hoisting ropes below the Cable pulleys are guided in parallel, so this is an additional stabilization of the load suspension device and thus the load.
  • the size of the Load oscillation only by the luffing movement of the boom and its load certainly.
  • the pendulum length approximately between the deflection roller of the handlebar and the load handler remains the same, the intended increase in throughput and thus the Cost savings achieved when handling piece and bulk goods.
  • the present invention is based on the application of the The luffing crane known single-link system, combined with the partial advantageous use of the double link system ("discontinuous conveyor 1" by Prof. Dr.-lng. tech. h.c. F.KURTH, pages 138 - 139, point 3.6.2.3. and 3.6.2.4).
  • FIG. 1 the port crane provided for container handling is in its Working position shown.
  • the harbor mobile crane is labeled 1 in total, the front a quay 2 lying container ship with 3.
  • the mobile harbor crane consists of the Undercarriage 4, the support 5, the tower 6 and the luffing jib 7.
  • the minimum Outreach of the luffing jib 7 is shown in dash-dot lines at 7.1.
  • Two jacks 8.1 and 8.2 are arranged below the tower 6. That to the preferably four lifting ropes 9.1 and 9.2 attached load suspension means 10 is in For example, a spreader intended for ISO containers that receives the load 11.
  • the luffing jib 7 is adjusted by a rope-operated luffing mechanism 12, in the upper one Part of the luffing jib 7 is a link 13 pivotally mounted at 14. At the opposite end of the articulation point 14 are large dimensions Rope pulleys 15.
  • Figure 3 shows the geometric movement of the luffing jib 7 and the Handlebar 13 when rocking from one boom end position to the other Boom end position.
  • the minimum outreach of the luffing jib 7 is 7.1 designated.
  • Guided by the handlebar 13 and the tether 16 describes the middle the cable pulley 15 has a path 19 which runs approximately horizontally, specifically analogous to the horizontal load path 20 of the load 11.
