Description

P34401NLO0
A MOBILE HEAVY LIFT CRANE SYSTEM The present invention relates to the field of mobile heavy lift crane systems.
In the art of heavy lifting mobile crane systems are known, e.g. as disclosed in WO2010/121134, WO2019/050405. An example of a heavy lifting mobile crane system is the SK10,000 crane system that has been developed by the company ALE.
Generally a mobile heavy lift crane system is composed of a crane comprising: - a crane carriage, comprising a base and track engaging members that are configured to engage with a corresponding track of a crane track assembly, - a main boom, that is pivotally relative to the base of the crane carriage about a main boom pivot axis, and has a main boom tip, - a back mast, that is pivotally relative to the base of the crane carriage about a back mast pivot axis, and has a back mast tip, - an adjustable length arrangement between the back mast and the main boom, - a counterweight, that is suspended from the back mast, - a track arrangement configured to be installed on the ground and comprising: - a circular slew track assembly extending over at least a slew arc about a slew center, comprising at least a pair of concentric first and second slew tracks.
The crane is so large that it is commonly assembled at the location of the hoisting job, e.g. at a refinery, power plant, etc. Commonly the main boom and the back mast are each assembled from modules. The track assembly commonly comprises load spreading boards on which the tracks are mounted, so that loads are distributed in view of the allowable ground pressure.
2.
The present invention aims to provide mobile heavy lift crane systems having an enhanced versatility and/or enhanced operational efficiency. The present invention provides a mobile heavy lift crane system according to claim 1.
Herein, the design of the crane carriage in conjunction with the design of the track arrangement, allows for an operation wherein the crane is moved over the rectilinear track assembly into a transfer position wherein the track engaging members of the first and second swivelling chassis are each arranged at a junction of the track arrangement, where the track engaging members are brought into alignment with the respective circular slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly.
In practice, this may allow for placing the slew track assembly at the location where the actual hoisting job, e.g. of a refinery column, is to be done. Often, at this location there is limited or insufficient space available for the assembly of the crane, which often entails horizontal assembly of the main boom on the ground before bringing the assembled main boom (and any jib when present) into a raised position. In practice, the main boom, possibly with jib, may be over 100 meters long. The inventive system allows to extend the rectilinear crane track from said slew track assembly to a remote location where there is sufficient clear ground space for assembly of the crane, e.g. including horizontal assembly of the main boom, possibly with a jib. Once assembled, the crane can then be moved, with the main boom raised, over the rectilinear crane track to the slew track.
Due to the provision of junctions, and the pivoting functionality of the sets of one or more track engaging members, e.g. one or more skid members, these track engagement members can be brought into alignment with the respective circular slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly. The pivoting can be done by actuators, e.g. hydraulic actuators, that may be integrated with the carriage but can also be embodied as separate tools that are employed for this purpose. The swivelling functionality of the chassis of the carriage, allows for a difference of width between the rectilinear crane track and the slew track. As disclosed herein, the swivelling functionality may also allow for other configurations of the mobile heavy lift crane system.
In an embodiment, the track arrangement further comprises a rectilinear counterweight track assembly, that is configured to be arranged parallel to the rectilinear crane track assembly,
-3- preferably extending to the slew center, wherein the counterweight is configured to a moved over the rectilinear counterweight track assembly, e.g. in unison with the crane carriage of the crane moving over the rectilinear track assembly into the transfer position. The counter weight may thus assist in keeping the main boom, and possibly a jib, in raised position whilst travelling over the rectilinear crane track to the transfer position. For example, the counterweight is located at the slew center or in proximity thereof, during performance of a hoisting job with the crane. The provision of the rectilinear counterweight track assembly allows for assembly of the counterweight at a location remote from the slew track, e.g. also avoiding constraints related to the location where the actual hoisting job is to be performed.
In embodiments, the rectilinear counterweight track assembly intersects the circular slew track assembly, e.g. an end portion of said semi-circular slew track assembly. In embodiments, the counterweight is configured to be arranged in the slew center whilst performing a hoist job, and wherein a swivel is provided between the counter weight and the back mast. In embodiments, the crane has a main hoisting assembly comprising at least one main hoist load connector, e.g. a crane hook, a main hoist cable, and a main hoist winch, wherein said main hoist winch is mounted on the crane base. In embodiments, the slew track arrangement has a first and a second slew track, wherein the first and second rectilinear crane tracks respectively intersect the first and second slew track at two junctions.
In embodiments, the circular slew track comprises concentric first, second, and third slew tracks, wherein the crane track has first and second parallel rectilinear crane tracks, where the first crane track intersects the first slew track and the second slew track at at least one junction, and wherein the second rectilinear crane track intersects the second and third slew track at at least one junction, so that — in operation - the crane is movable over the rectilinear track assembly into a transfer position wherein the track engaging members of the first and second swivelling chassis are each arranged at a junction of the track arrangement, where the track engaging members are brought into alignment with the respective circular slew track, such that one set of track engaging members of the first swivelling chassis engages on the first slew track, the other set of engaging members of the first swivelling chassis engages on the second slew
-4- track, and one set of track engaging members of the second swivelling chassis engages on the second slew track, the other set of engaging members of the second swivelling chassis engages on the third slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly.
In embodiments, the counterweight carriage comprises sets of one or more track engaging members, e.g. one or more skid members, each set being configured to engage with a corresponding track of the counterweight track assembly, wherein each track engaging member is pivotal about a respective vertical pivot axis, wherein the rectilinear counterweight track assembly intersects the circular slew track assembly at junctions, so that — in operation — the counterweight is movable into a transfer position wherein the track engaging members of the counterweight carriage are each arranged at a junction, where the track engaging members are brought into alignment with the respective circular counterweight track. The present invention also provides a twin mobile heavy lift crane system comprising two cranes and a track arrangement configured to be installed on the ground to support the two cranes. Herein each of the two cranes comprises: - a crane carriage, comprising a base, a first swivelling chassis and second swivelling chassis, the first and second swivelling chassis being adapted to support the base, each chassis being swivelling relative to the base about a corresponding first and second vertical chassis swivel axis respectively, wherein each chassis has a set of one or more track engaging members, e.g. skid members, at opposite sides of the respective swivel axis and each set being configured to engage with a corresponding track of a crane track assembly, wherein each track engaging member is pivotal relative to the respective chassis about a respective vertical pivot axis.
The track arrangement comprises a circular slew track assembly extending over at least a slew arc about a slew center, wherein the circular slew track comprising at least concentric first, second, and third slew tracks, wherein the second track is intermediate the first and third track, and wherein the crane base is configured such that one set of track engaging members of the first swivelling chassis engages on the first slew track, the other set of engaging members of the first
-5.
swivelling chassis engages on the second slew track, and wherein the crane base is configured such that one set of track engaging members of the second swivelling chassis engages on the second slew track, the other set of engaging members of the second swivelling chassis engages on the third slew track.
This twin crane arrangement allows to perform hoisting jobs where both cranes are used to handle the load. The ground pressure is relatively limited as the two cranes stand on at least concentric first, second, and third slew tracks.
In a practical advantageous embodiment, the main boom pivot axes of the two cranes are aligned with one another in at least one relative position of the cranes with respect to one another on the circular slew track. This allows, for example, for identical and synchronized luffing motions of the main booms of the two crane.
In embodiments, the track arrangement further comprises a circular counterweight track assembly, that is configured to be arranged concentric with the crane track assembly, extending about the slew center, wherein each counterweight is configured to be moved over the circular rectilinear counterweight track assembly, e.g. in unison with the crane base of the crane moving over the slew track assembly during slewing of the cranes.
In embodiments, the circular slew track comprises concentric first, second, and third slew tracks, wherein the crane track has first and second parallel rectilinear crane tracks, where the first crane track intersects the first slew track and the second slew track at at least one junction, and wherein the second rectilinear crane track intersects the second and third slew track at at least one junction, so that — in operation - the crane is movable over the rectilinear track assembly into a transfer position wherein the track engaging members of the first and second swivelling chassis are each arranged at a junction of the track arrangement, where the track engaging members are brought into alignment with the respective circular slew track, such that one set of track engaging members of the first swivelling chassis engages on the first slew track, the other set of engaging members of the first swivelling chassis engages on the second slew track, and one set of track engaging members of the second swivelling chassis engages on the second slew track, the other set of engaging members of the second swivelling chassis engages on the third slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly.

The swivel 52 then allows for the slew motion of the crane 1 about the slew center 101. The crane system shown in figures 1 and 2 can be installed at a hoisting site to hoist a load using the following method: - installing the circular slew track 100 assembly at the hoisting site, - installing the rectilinear crane track assembly 120, extending from said hoisting site to a crane assembly location, - assembly of the crane 1 at the assembly location, e.g. including assembly of the main boom in horizontal orientation and raising of the assembled main boom into a raised position (see e.g. figures 15a-i),
-15- - moving the assembled crane 1 over the rectilinear crane track assembly 120 into a transfer position wherein the track engaging members 15, 16, 17, 18 of the first and second swivelling chassis are each arranged at a junction 131, 132, 133, 134 of the track arrangement, bringing the track engaging members into alignment with the respective circular slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly. The figures 3a-c illustrate the above method, wherein the crane 1 is assembled at location A and then moved over the track 120 to the transfer position shown in figure 3a. Here, the track engaging members 15, 16, 17, 18 are moved out of there alignment with track 120 and into alignment with the track 100. In particular with skid type members 15, 16, 17, 18 this can be done rather easily, as the junction effectively needs to be no more than a break in the skid rails and an extended skid surface at the junction to allow the re-alignment of the members 15, 16, 17, 18. Due to the load, e.g. due to weight of the crane, during this alignment, actuators 170 are provided to perform the pivoting motion (see figure 3c). As preferred, skid actuator, e.g. hydraulic skid actuators 170, are used for the alignment. In embodiments, the same actuators 170 are used to skid the crane or counterweight of the associated track(s). Figures 4 and 5 illustrate that the crane 1 cannot only be used in combination with a two track rectilinear crane assembly, or two track slew track assembly, but also with a tri-track slew track assembly which is discussed in more detail with reference to figures 16 — 26. This is in particular due to the provision of the swivel functionality of the chassis 11, 12 of the carriage of the crane 1 in combination with the pivoting functionality of the members 15, 16, 17, 18.
It is shown in figure 5 that the circular slew track 101 is a tri-track having concentric circular first 101, second 102, and third slew tracks 103.
The carriage allows for positioning of the crane 1 on the slew track such that one set of track engaging members 15 of the first swivelling chassis 11 engages on the first slew track 101, the other set of engaging members 16 of the first swivelling chassis 11 engages on the second slew track 102, and one set of track engaging members 17 of the second swivelling chassis 12 engages on the second slew track 102, the other set of engaging members 18 of the second swivelling chassis 12 engages on the third slew track 103. This allows the crane to perform slewing motion about the slew center 101 whilst supported on the slew track assembly. The loads are distributed more even than with a support of the crane on just two slew tracks.
-18- The figures 7 — 9 illustrate the hoisting of a load, e.g. a column of a refinery or other chemical plant. Figure 10 illustrates a variant wherein a further rectilinear crane track 160 adjoins the circular slew track as an extension thereof, angled relative to the crane track 120, e.g. perpendicular to the crane track 120 as shown here. Figure 10 illustrates that a further rectilinear counterweight track 145 extends from the slew center 101 parallel to the further rectilinear crane track 160, angled relative to the track 140, e.g. perpendicular to the track 140 as shown here. Figures 11a, b and 12 illustrate a possible embodiment of the modules 300 of the legs of the main boom 20. Each module 300 forms half of a section of the leg, and has two longitudinal chords 301, 302 interconnected by a latticed web 303 in one plane, preferably a top plane or a bottom plane of the module. The side planes of the module are formed by diagonal trusses 304, 305 in a zig-zag formation on the respective chord. The trusses adjoin in pairs at connection points 306 remote from the chord. The connection points 306 are provided with tabs allowing two modules to be joined with their connection points 306, e.g. by providing a pin or bolt through aligned holes in the tabs as shown here.
For example, one module 300 can be transported on a trailer of a lorry. Figure 13 shows the counterweight 50 and the associated carriage 51 having a base 51a and four sets of one or more track engaging members 55, 56, 57, 58, e.g. one or more skid members. Each set is configured to engage with a corresponding track of the counterweight track assembly, and each track engaging member is pivotal about a respective vertical pivot axis 55a, 56a, 57a, 58a relative to the base 51a. Figures 15a — 15i illustrate the horizontal assembly of the main boom 20 and jib 25 of the crane 1 at the assembly site, remote from the location of the slew track 100, e.g. at the end of the track 120. A regular road travelling mobile telescopic boom crane 400 is used to handle the modules 300 of the boom 25 during the assembly thereof, as well as modules of the jib 25, and other parts like the stay mechanism of the jib.
-17- The carriage of the crane 1 is placed, e.g. assembled from components, on the track 120 at the assembly site, and then the main boom 25 is built horizontally from the carriage towards the tip of the main boom. Then the jib 25 and the related stay mechanism is assembled.
Figure 15f shows the assembly of the back mast 30, also from modules using a mobile crane
400. The back mast 30 is, as preferred, also assembled in horizontal orientation. Figures 15g — 15i illustrate the further assembly of the crane 1. The adjustable length assembly 40, also known as luffing assembly, is provided between the tip of the back mast 30 and the tip of the main boom 20, e.g. including a winch operated cable assembly 41 and pendant 42 to the tip of the boom 20.
As shown in figure 15g, the counterweight 50 can be assembled slightly offset from the back mast still in horizontal orientation.
Once the main components of the main boom 20, back mast 30, assembly 40, main hoist, etc. are assembled, the back mast 30 is raised first and connected to the counterweight 50 that is moved into position under the tip of the mast 30. Then the assembly 40 is used to bring the main boom 20, and jib 25, into a raised position, e.g. first to allow the crane hook 200 to be fitted.
Figure 16 shows a twin mobile heavy lift crane system comprising two cranes 1 as discussed above and a track arrangement configured to be installed on the ground to support said two cranes 1.
The track arrangement comprises a circular slew track assembly extending over at least a slew arc about a slew center, wherein the circular slew track comprising at least concentric first 101, second 102, and third slew tracks 103.
As discussed with reference to figure 5 the crane base is configured such that one set of track engaging members of the first swivelling chassis engages on the first slew track, the other set of engaging members of the first swivelling chassis engages on the second slew track, and wherein the crane base is configured such that one set of track engaging members of the second swivelling chassis engages on the second slew track, the other set of engaging members of the second swivelling chassis engages on the third slew track.
-18- It is shown that the main boom pivot axes 21 of the main booms 20 of the two cranes 1 are aligned in at least one relative position of the cranes 1 with respect to one another on the circular slew track 100.
The track arrangement further comprises a circular counterweight track assembly 180, that is configured to be arranged concentric with the crane track assembly 100, extending about the slew center 101. Each counterweight 50 is provided with a carriage 51 that is configured to be moved over the circular counterweight track assembly 180, e.g. in unison with the crane base of the crane 1 moving over the slew track assembly 100 during slewing of the cranes.
The figures 22 — 26 illustrate that the tri-track slew track assembly 100 is equally applicable in combination with a crane track assembly 120 having first and second parallel rectilinear crane tracks 121, 122, e.g. to allow assembly of the cranes 1 remote from the location of the slew track assembly 100.
As shown the first crane track intersects the first slew track and the second slew track at at least one junction, and the second rectilinear crane track intersects the second and third slew track at at least one junction, so that — in operation - the cranes 1 are each movable over the rectilinear track assembly into a transfer position wherein the track engaging members of the first and second swivelling chassis are each arranged at a junction of the track arrangement, where the track engaging members are brought into alignment with the respective circular slew track, such that one set of track engaging members of the first swivelling chassis engages on the first slew track, the other set of engaging members of the first swivelling chassis engages on the second slew track, and one set of track engaging members of the second swivelling chassis engages on the second slew track, the other set of engaging members of the second swivelling chassis engages on the third slew track, allowing the crane to perform slewing motion about the slew center whilst supported on the slew track assembly.
Figures 17, 28 illustrate a twin mobile heavy lift crane system comprising two cranes 1 and two track arrangements each configured to be installed on the ground to support one of said two cranes 1. The cranes 1 here are shown without jib 25. Here, each track arrangement is configured to be installed on the ground and comprises a circular slew track assembly 100 extending over at least a slew arc about a slew center, wherein the circular slew track assemblies are spaced apart, e.g. with as semi-circular slew
-19- tracks having center regions close to one another and end regions facing away from one another.
The hoisting of a load can then be done by the two cranes 1 as shown herein.
