Definitions

  • the present invention relates to a port dock crane for lifting and handling loads, in particular containers.
  • the dock cranes are moved into position in order to prepare for the actual loading or unloading. These cranes are positioned on the dock in front of the ship with their jibs up.
  • the cranes are each equipped with their own spreaders. For some years now these so-called “twin-lift” spreader models have been utilized. These are able to handle one forty-foot container or two twenty- foot ones per cycle, and unload up to 35/40 forty-foot containers or about 60/70 twenty-foot containers per hour.
  • the port is activated for all the successive sorting and distribution activities of the containers from the inbound dock to the yard or vice versa.
  • the unloading of containers is done:
  • the port is equipped with self-loading and self- unloading equipment such as fork-lift trucks, reach-stackers or straddle carriers that can transfer the unloaded containers to the yard where they are then stacked.
  • self-loading and self- unloading equipment such as fork-lift trucks, reach-stackers or straddle carriers that can transfer the unloaded containers to the yard where they are then stacked.
  • the dock cranes are able to increase their productivity. The reason for this is because by placing the container directly on the ground rather than having to place it on a trailer they can work more quickly and securely.
  • the high daily layover costs of a ship in a port, in particular for large ships also have to be taken into account.
  • ports that are able to release ships in a shorter time are the ones which will be able to acquire more and more traffic and attract new shipping companies. Therefore it is of great importance for ports to increase their productivity during all phases of the container handling, so that port operators can release ships as soon as possible.
  • the main object of the present invention is to speed up activities of loading and unloading off and on ships, starting from the system of unloading containers on the ground in order to avoid any downtime in the area under the cranes.
  • Another object of the present invention is to reduce containers loading and unloading time, on equal number of cranes used.
  • the present port dock crane for lifting and handling loads, in particular containers, which comprises at least a first and a second vertical structure sliding on the ground, at least a scaffold frame mounted substantially horizontally on said vertical structures, and at least a substantially horizontal jib which extends overhanging from said scaffold frame, characterized in that at least two sliding trolleys along said jib are mounted, and each one connected to respective loads lifting units suitable for operate contemporarily with each other in order to lift and/or lower different loads to each other.

  • a substantially horizontal jib 5 extends overhanging from the scaffold frame 4a, 4b.
  • Two sliding trolleys 6 along the jib 5 are mounted and provided with a pulleys series 7 which create the funicular movement of these trolleys and the relative load lifting and lowering, with respective lifting units 8 suitable for working contemporarily to lift and/or lower a plurality of containers 9 different to each other.
  • the first vertical structure 2a, 2b is composed of a plurality of vertical legs 2a mounted on a carrier beam 2b which connects them and which lays on an orthogonal direction respect to jib 5.

  • the second vertical structure 3a, 3b is composed of two vertical legs 3a mounted on a carrier beam 3b which connects them and which lays on an orthogonal direction respect to the jib 5.
  • the second vertical structure 3a, 3b is approximately positioned at the median portion of the space defined between the first vertical structure 2a, 2b and one end of jib 5.
  • the first vertical structure 2a, 2b is located near the edge of the dock 10 for loading/unloading the containers 9 on/off the ship 1 1 with jib 5 which extends itself to completely cover the hold of the ship 1 1 in order to carry out the lifting and the placing of the containers 9 off and on said hold.
  • To the carrier beams 2b, 3b are associated two series of wheels 12, 13 sliding on respective rails (tracks) 14 and having handling means suitable for making the entire crane 1 mobile along an orthogonal direction respect to jib 5 and parallel to the edge of the dock 10.
  • These handling means aren't shown in the figures and are composed of motorized gearboxes mounted in a number to meet the necessary power requirement for handling the crane 1 on tracks 14.
  • the wheels 12, 13 are made of steel and are mounted in double pairs on appropriate supports or wheel boxes 15, associated to respective motorized gearboxes suitable for allowing their movement.

  • the cylinders (hydraulic jacks) 17 are connected together by a hydraulic circuit 15 that allows the transfer of the same level of oil and pressure between one cylinder and another and which hydraulic circuit is controlled by a central unit that constantly maintains the preset pressure depending on the load in any movement.
  • the entire scaffold frame 4a, 4b is mounted on the top of legs 2a, 3a and consists in a perimeter structure formed by cross beams 4a, which are parallel to the carrier beams 2b, 3b, and by longitudinal beams 4b, which connect the cross beams 4a and which are parallel to jib 5.
  • the cross beams 4a are associated with jib 5.
  • Jib 5 is formed by a moving front section oriented towards the sea which can be raised, and if lowered, is stretched out on the whole of the hold of the ship 1 1 , and by a rear section oriented towards the land, which is fixed and integral with the cross beams 4a, which in turn are connected to the vertical legs 2a, 3a.
  • the length of the rear section is almost equal to that of the front section of jib 5 to allow containers 9 to be unloaded also in the rear part of the crane 1 as well as from the part between the vertical bearing structures 2a, 2b and track 14 in order to distribute containers 9 rationally and efficiently in an optimized space in order to distribute them to the yard.

  • Jib 5 has normally two sliding trolleys 6 along the same jib and a machine room which has two lifting units (lifting winches) 8, one for each trolley 6.
  • Each trolley 6 supports at least two spreaders 19 and since the crane 1 is equipped with two trolleys 6, there is a preferably total number of four spreaders 19 that can be handled simultaneously and independentlyof each other, in order to load or unload four forty-foot containers or eight twenty-foot container.
  • Each trolley 6 has an equipped crosspiece 20 for holding the spreaders 19 in order to handle containers 9.
  • a spacer element 21 is mounted which connect two spreaders 19, which contemporarily handle two containers 9 keeping these containers distanced to each other up to two meters (figure 8) or adjacent (figure

  • a ottimale work cycle could be: beginning from the load or unload phase of ship 1 1 the first trolley 6 of jib 5 will start to unload the last container
  • rear trolley will start which will take containers 9 of row group 25, reaching for first on dock 10 and it will unload in the farthest place from ship 1 1 (covering B route of figure 1 up to D unloading zone) in order to cover almost the same distance covered by the front trolley and synchronizing themselves up to the complete end of loading and unloading operations of containers 9 on the ground or on the ship 1 1. Since distances to cover are essentially equals for both trolleys 6, work cycles are practically the same, up to the end of bay portions covered by jib 5 and by their four spreaders 19.
  • Crane according to the invention, has the peculiarity to have a control cabin for each bringing spreader trolley which allows every operator to operate and control all the operations in a simply and securely way.
