Definitions

  • the invention relates to a crane arrangement, and more specifically to a crane arrangement for use on board a ship.
  • Such an arrangement can be used for almost any type of cargo and has a high operating efficiency. Its weight lies within limits which also allow it to be readily built into existing ships.
  • An especially wide-tracked support of the car is thus achieved so that a wide reach can be obtained with sufficient stability even without additional supporting means.
  • the car advantageously extends beyond the vertical swinging plane and is provided with an opening for the passage therethrough of the cargo.
  • Pendulum-like swinging movements of the load when using high working speeds can be effectively reduced it the load hangs on two points of the boom head arranged spaced apart in the plane of movement of the boom head.
  • the head of the boom may be of T-shape.
  • the two cars with their booms and lifting mechanisms can be driven in synchronism with the aid of a common control device. By switching on or switching olf this device it is then possible to use the cars individually or jointly.
  • the two 3,228,534 Patented Jan. 11, 1966 "ice cars are advantageously arranged for being coupled with each other, in which case only one of the two cars is provided with a travelling mechanism.
  • FIG. 1 is an elevational view of a crane arrangement according to the invention
  • FIG. 2 is a plan view of FIG. 1;
  • FIG. 3 is a side elevation of part of the crane arrangement of FIGS. 1 and 2.
  • the crane arrangement illustrated comprises two cars 2 which bridge a cargo hatch 1 of a ship, the cranes having booms 4 which are swingable about horizontal axes 3.
  • the cars have supporting wheels 5 by means of which they can travel in the longitudinal direction of the ship, on rails 6 arranged longitudinally of the hatch.
  • the booms 4 are swingable on the axes 3 so that the boom heads 8 move in vertical planes 7.
  • the plane 7 for each boom head 8 is ollset relative to the vertical plane passing through the boom foot 29.
  • the cars 2 extend beyond the vertical swinging plane 7 and are provided with a joint opening 9 for passage therethrough of the cargo being loaded.
  • each boom hangs on two points which are separated from each other in the swinging direction, one point 10 being a fixed suspension point on the boom head 8 and the other being constituted by a cable pulley guide 11.
  • the boom head 8 is formed as a T-shaped transverse head, which lies in the swinging plane 7.
  • Each boom is provided at its mounting end with a short lever arm 4a on which a hydraulic drive for effecting the rotation of the boom about the axis 3 engages, the hydraulic drive comprising two pivotally mounted cylinders 12 with piston rods 13.
  • the load cable 14 extends from the fixed point 10 on the boom head, over a load supporting pulley 15 to the guide pulley 11 on the transverse head of the boom and from there to and fro in a plurality of passes over pulley blocks 16, 17 provided on the head of the boom and on a column 18 of the car, and finally over a last pulley of the pulley block 17 on the car column to the winding mechanism diagrammatically shown at 31 which is provided in the column of the car. Due to this arrangement of the load cable 14, a horizontal path of moveemnt for the load is achieved on swinging of the boom, as is indicated in FIG. 1 by the broken line 19.
  • the point 20 of intersection of the line of the cable 14 with the axis of the pulley block 17 is arranged perpendicularly above the point 21 of intersection of the centre line of the boom and the axis of rotation of the boom.
  • the two cars and booms can be operated independently or alternatively commonly driven. Joint operation of the cars and booms is illustrated in FIG. 2.
  • the two load supporting pulleys 15 are coupled together and the two crane arrangements are driven in synchronism.
  • a common control device illustrated diagramatically at 30 in the drawing is provided.
  • the two cars simply abut against each other by their ends which face one another, or may alternatively be coupled together.
  • Each car is provided with a brake (not shown).
  • separated travelling mechanisms may be provided, but alternatively, one
  • travelling mechanism may be dispensed with so that one of the cars can only be displaced with the aid of the travelling mechanism of the other car.
  • said boom body portion being incline-d with respect to said axis whereby said boom head portion has a plane of movement displaced longitudinally of and substantially parallel to a vertical plane passing through said foot of said boom perpendicular to said axis.
  • said car being mounted for movement fore and aft of a ship
  • said boom having a foot, a head and a body portion and being mounted on said car for movement with said car and for pivoting about a substantially horizontal axis extending fore and aft of said ship, said boom body portion being inclined with respect to said axis whereby said boom head portion has a.
  • said loading means comprising a pulley block on said boom head
  • a further pulley block mounted on a column provided by said car, a load supporting cable, a winding means for said cable, said cable extending in a path from said winding means over said first and further pulley block,
  • each of said cars being synchronously driven by a common control means whereby said cars cooperate to lift a single load therebetween.
