Definitions

  • the invention relates to a crane as well as a method of transporting and installing such a crane.
  • Cranes that are designed and constructed for use in harbour areas for loading and unloading goods into and from a ship moored to a quay have increasingly large dimensions. This is particularly the case for cranes that are equipped for handling containers or mass goods such as ore. Especially in the design of container cranes time and again stricter requirements with respect to the size and handling capacity have to be met. One may recall the first generation container cranes being already relatively considerably large structures. Furthermore, a seventh generation container cranes is being built surpassing by far the first generation container cranes in size.
  • a main object of the invention is to provide a crane as well as a method of transporting and installing such a crane which offer a solution to the above problematical circumstances.
  • the invention provides a crane for loading and unloading goods, particularly containers, into and from a ship, respectively, comprising a superstructure and a substructure supporting said superstructure, wherein said substructure is to be provided with means for positioning the crane on a basis, e.g. a quay, and has structure members extending substantially vertically, and wherein said superstructure comprises a bridge structure such as a trolley girder, including structure members extending substantially horizontally, and further comprising means for attachment of said superstructure on said substructure, characterized in that said attachment means are releasable and are located in the lower part of the substructure so that the bridge structure is located in the lower part of the crane.
  • the crane of the invention is designed in such a way that the complete superstructure or topside can be mounted at a lower level than that of its final operation position.
  • the crane is assembled with the bridge structure in the lower part of the crane.
  • the crane is transported to a harbour by a transport vessel. Since the centre of gravity of the crane will be located at a level that is far beneath the level of a crane fully erected, the stability of the crane on deck will be improved to a great extent.
  • due to the sort of collapsed state of the crane dynamic forces that are borne on the wind and act on the crane will be reduced.
  • the crane is landed, whereupon the attachment between the topside and the substruc ture is released and the topside is lifted by any suitable means up to its working postition on top of the substructure and secured at this place by any proper securing means, such as the usual welds.
  • the crane of the invention may be erected on the quay of destination by means of floating cranes. It will be clear that the increasing sizes of the container cranes require larger constructions of these floating cranes, which will be very costly and may have to be taken care of time each time a new generation container cranes is introduced. Furthermore, this method requires the presence of such large floating cranes on the spot. In order to put an end to the need for floating cranes of the proper size for the actual installation of the crane of the invention which is very hard to fulfill in less developed harbours, the crane of the invention would preferably have hoisting means to be used for vertically displacement of said superstructure relative to said substructure after release of said attachment means towards a position wherein said superstructure is located at the top of the substructure.
  • said hoisting means comprise hoisting cable sheave means for engagement by and guidance of hoisting cable means engaging said superstructure and being connected at one end to a hoisting winch means.
  • the other end of the cable will be fastened to the superstructure or the substructure, depending on the chosen lay-out of the hoisting mechanism.
  • the invention also relates to a method according to which the crane of the invention is transported on deck of a transport vessel.
  • the method is related to preparing a crane for transport and subsequent transport of that crane, in particular a container crane, and comprises a superstructure provided with a bridge structure such as a trolley girder, and a substructure for supporting said superstructure, wherein said superstructure is releasably attached to said substructure at a location in the lower part of said substructure, and subsequently said crane is placed on deck of a transport vessel and said vessel is set to sail.
  • At least two cranes are prepared for simultaneous transport on a same transport vessel, wherein the superstructure of one crane is releasably attached to its substructure at a level that is different from the level at which the superstructure of the other adjacent crane is releasably attached to its substructure.
  • the substantially horizontally extending structure members of the lowered superstructures of adjacent cranes stored on deck may partly overlap one another so as to enable these cranes to be placed close to one another, thus saving space.
  • the method of the invention is related to the transport of a crane and subsequent installation of that crane, in particular a container crane, comprising a superstructure provided with a bridge structure such as a trolley girder, and a substructure for supporting said superstructure, said superstructure having been releasably attached to said substructure by a releasable attachment at a location in the lower part of said substructure, said crane having been stored on deck of a transport vessel, wherein the method comprises the following stages:
  • step d) said superstructure is guided by said substructure during lifting.
  • Said lifting is preferably carried out by using hoisting cable sheave means on said substructure and/or said superstructure, hoisting winch means and hoisting cable means connected at one end to said superstructure or said substructure and at the other end to the hoisting winch means.
  • the crane of figure 1 comprises a substructure 3 and a superstructure 2, 2' which is depicted in dashed lines when it is in the lowered position to form the crane of the invention (see reference numeral 2) as well as in full lines when it is in lifted, final position on top of the substructure (see reference numeral 2').
  • Substructure 3 comprises four postmembers or legs 12, 13, i.e. waterside legs 12 and landside legs 13 which are connected to one another at the lower ends by means of transverse or tie beams 14, and moreover, by leg-diagonals 15.
  • the lower ends of the waterside legs 12 are connected to one another by a transverse sill beam 17 and the lower ends of the landside legs 13 are connected to one another by a transverse sill beam 18.
  • Near the connection between the post members 12, 13 and the sill beams 17, 18 roller sets or bogies are to be mounted in order to enable the displacement of the crane in use.
  • On top of the posts 12,13 upper hoisting assemblies 23, 25 are mounted. A more detailed description of this upper hoisting hoisting assembly is given below.
  • Superstructure 2, 2' comprises a trolley girder 19 (trolley is not shown), including two parallel, horizontally extending beams 16, each of which comprises a landside part 5 and a waterside part or boom 4, which are articulated at 9 in order to enable the boom to be held in a position in which it projects upwardly and is inclined at an angle to the landside part 5.
  • Such an orientation of the boom 4 is advantageous during transport as it permits an adjacent crane to be stored on deck in a position close to the first crane.
  • the super structure 2, 2' also comprises two transversely extending trolley girder support beams 20, 21.
  • the superstructure 2, 2' comprises an upstanding, so-called "A"-frame 11, which is supported by and fastened to the waterside trolley girder support beam 20 and diagonal support bars 6 extending between the landside trolley girder support beam 21 and the top beam of the "A" frame 11.
  • tension bar strings 7 and 8 are provided which extend from the top beam of the A-frame 11 to the boom 4 and to the outer end of the landside part 5 of the trolley girder 10, respectively so as to suspend the sections of the trolley girder projecting horizontally outwardly from the substructure 3.
  • Lower hoisting assemblies 22, 24 are mounted onto the ends of trolley girder support beams 20, 21, respectively, and are described further below.
  • the superstructure 2, 2' is provided with a machine house 10 for operating the trolley.
  • FIG. 3A and 4A the upper hoisting assembly mounted onto the upper end of each of the waterside legs 12 is shown.
  • a transverse upper spreader 27 carrying four sheave boxes 29 is removably secured to console assembly 36 at 39 and 40, said console assembly 36 being bolted to the upper end of leg 12.
  • the sheave boxes 29 are bolted to the lower flange of upper spreader 27 and each of them comprises two, three or four parallel, coaxially placed sheaves 31 for cable 40.
  • an additional sheave box 32 having a single sheave is arranged perpendicular to the other sheave boxes 29.
  • the upper spreader 27 projects horizontally out of the circumference of leg 12 so that the sheave boxes 29 have sheaves 31 that are arranged such as to receive a cable extending upwardly from the lower hoisting assembly.
  • the lower sheave assemblies 22, 23 are shown which are arranged at both ends of trolley girder support beams 20 and 21, respectively.
  • the lower sheave assembly 22 comprises a lower spreader 26 which is secured to the lower side of support beam 20, on top of which, at either side of the support beam 20, sheave boxes 28 are mounted, each of which comprises two or three parallel, coaxially positioned sheaves 30.
  • the sheaves 28 are arranged such as to lie substantially vertically beneath sheaves 29.
  • winch assemblies 33-35 are mounted onto respective ends of sill beams 17, 18.
  • the winch assemblies 33-35 comprise a mounting frame 33 for mounting onto the sill beam, a winch drum 34 rotatably mounted into frame 33 and a motor 35 for rotating winch drum 34.
  • the winch assembly is arranged so as to enable a winch cable to extend substantially vertically up to sheave 32 of the upper hoisting assembly as shown in figures 3A and 4A.
  • the area in which the cable can extend is indicated by dash lines.
  • trolley girder part 5 is shown which is connected to beam 20 by the mounting part 40 in order to support beam 20 by way of suspension thereof.
  • the support beam 20 (as well as support beam 21) is provided with mounting flange 37a which is releasably attached by means of bolts to a mating flange 37b on the inner side of post 12, in the lower part thereof.
  • a mounting flange 38b is provided at the upper end of post 12, at the inner side thereof.
  • Mounting flange 38b corresponds to mounting flange 37b, so as to enable an attachment of mounting flange 37a thereto.
  • Figure 5A, 5B and 5C show vertical cross-sections along lines VA-VA, VB-VB, VC-VC, respectively, of the releasable connection of support 20 to post 12.
  • the flange plate 37a of support beam 20 is attached to flange plates 37b of post 12 by means of bolts 41.
  • pinlike members 44 are fastened which fit into holes 46 provided in support block 45 fastened to the upper side of lower spreader 26.
  • a recess 48 At the side facing the inner side plate 47 of post 12 lower spreader 26 is provided with a recess 48 in which a roller 42 is rotatably mounted.
  • Inner side plate 47 is strengthened by a transverse plate 43.
  • FIG 6 the rigging diagram is shown in the arrangement at the end of lifting or hoisting operations.
  • Cables 50 are attached to winches 34 at one end and wound up on the winch by the operation of motors 35 until the flanges 37a have reached a position facing flanges 38b. In that position the upper side of support beams 20, 21 may abut the lower side of upper spreader 27 so as to facilitate the positioning thereof.
  • cables 50 are guided upwards and downwards etc. between the lower sheaves 30 and the upper sheaves 31 and are finally fastened at 49 to the upper end of posts 12, 13.
  • the support beams 20, 21 are fastened with therein flanges 37a being connected to flanges 37b on posts 12, 13. Due to the low level of the flanges 37b this operation can be easily performed, even if very large superstructures are involved.
  • the crane of the invention would already permit transportation by a transport vessel, e.g. the dock ship as shown in figure 7. In that case hoisting means could be mounted only at the destination and removed again after completion of the lifting operation.
  • the crane may, however, be advantageous to equip the crane with the complete hoisting mechanism or parts of it prior to its transportation.
  • the upper spreaders 27 with sheaves 31 are mounted on top of the posts 12, 13, the lower spreaders 26 with sheaves 30 are placed somewhere on deck, and the winches 33-35 are mounted on sill beams 17, 18. Cables 50 may or may not have been rigged already through the sheaves.
  • the crane is embarked by moving it along the outriggers at the stern of the dock ship of fig. 7.
  • the lower spreaders 26 with sheaves 30 and bearing block 45 on their upper side are positioned below the ends of support beam 20, 21 so that pins 44 are inserted into holes 46 in bearing blocks 45.
  • the rigged cable is tightened by operating the winches in such a way that the cables are able to take over the weight of the superstructure 2 during the removal of the bolts, so as to permit disconnection of the flanges 37a from the flanges 37b.
  • the hoisting operation can be performed until the flanges 37a are at a level permitting their attachment to flanges 38b at the upper ends of posts 12, 13.
  • the lifting operation vertical, downwardly directed forces are exerted on the upper ends of posts 12, 13 at the sheaves 32, as a result of which a bending moment (see Arrow A in fig. 4A) is exerted on posts 12, 13.
  • roller 42 The main function of roller 42 is to exert a horizontal force on the inner sides of the legs 12, 13, so that the displacement resulting from the moment A is equalized and the support beams 20 and 21 are given free way in their upward movement.
  • the lower spreader may be easily removed by paying out the cables 50 again.
