Definitions

  • the invention relates to a hoisting crane, comprising a crane housing which can be slewed on a rotary slewing ring, a jib hingedly connected to the bottom part of said crane housing, luffing means in order to luff the jib in and out, a hoisting drum with drive motor fitted in or on the housing, and a hoisting cable which is to be wound on or off the hoisting drum and which runs over guide means at the top side of the crane housing and guide means at the free end of the jib.
  • Such cranes are commonly used on ships to load mixed cargo and containers into the holds and to unload them from the holds.
  • the problem of known cranes of this type is that, when the jib is in the fully luffed-in position, a vertical position of the jib is impossible, because the presence of the crane housing prevents this.
  • the hoisting apparatus suspended from the hoisting cable - usually a hoisting hook or spreader - will in this jib position therefore be at a horizontal distance which is not negligible relative to the crane housing, so that the mixed cargo cannot be placed directly below the crane housing in the holds of the ship. This leads to loss of hold space.
  • the object of the invention is to eliminate this disadvantage, and to this end the jib is designed as a lattice which is U-shaped in cross-section, and which accommodates a part of the crane housing in the fully luffed-in position, while the luffing means comprise at least one tension cylinder.
  • the pedestal crane shown comprises a crane housing 1 and a jib 3 hingedly connected thereto at 2.
  • the housing 1 contains a motor-driven winch drum 8 on which a part of a hoisting cable 6 is wound.
  • This hoisting cable forms a tackle and runs over tackle blocks 7 at the top side of the housing 1 and tackle blocks 8 at the free end of the jib 3 to a hoist hook 9 or other hoisting apparatus.
  • Two hydraulic tension cylinders 10 are connected at 11 hingedly to the crane housing 1 and at 12 hingedly to the jib 3, in order to luff the jib in and out.
  • the jib 3 is constructed from a lattice and is U-shaped in cross-section.
  • the design of the luffing means as tension cylinders 10 is also important for reaching of the vertical position of the jib in the fully luffed-in position thereof.
  • the tension cylinders have a small rotary cylinder radius during the luffing in and out of the jib.
  • Figure 3 shows that the part of the hoisting cable 6 extending between the hoisting hook 9 and the tackle block 8 runs at a short distance from the housing, so that piece goods can be placed and lifted below the crane housing 1.
  • the above-mentioned part of the hoisting cable with hook thus lies relatively far from the crane housing, so that the cargo cannot be placed directly below the crane housing. A considerable gain in loading capacity is achieved by means of the invention.
