Definitions

  • the present invention relates generally to the technical field of tower cranes, such as those used on construction sites of buildings. More particularly, this invention is concerned with tower cranes with so-called “suspended" driving cabins and, more specifically, it relates to a folding cabin-pivot unit for a tower crane of this type.
  • the "suspended" driver's cab can be associated with the pivot located at the top of the mast, and used for the orientation of the boom of the crane, to constitute an assembly designated as "cabin-pivot unit".
  • cab-pivot unit An example of a cab-pivot unit can be found in FR 2565950 A; the cabin here occupies a fixed position relative to the boom of the crane, the cabin-pivot unit not being provided folding.
  • the present invention aims to avoid all of these disadvantages, by providing an improved cabin-pivot unit which, while maintaining a simple and economical structure, makes it possible in particular to carry out in a quick and easy way the supply of the cabin in a position of service, while allowing the cabin to be folded in minimum space and without the addition of protection elements.
  • the driving cabin is articulated to the mast element by a double vertical hinge comprising, on the side of the mast element, an upper support and a lower support respectively fixed at the top and at the base of the mast element, and at the cabin side, an upper support and a lower support respectively fixed on the top and on the base of the supporting structure of the mast element.
  • cabin, the upper supports and the lower supports being connected by vertical axes, respectively upper and lower.
  • the attachment means of the lateral railing on the access platform to the cabin may comprise, on an outer edge of said platform, double corner boxes receiving the feet of the rails of the railing, fixing, according to the corner box used, the vertical or oblique orientation of these amounts, so the guardrail.
  • the cabin access platform still advantageously supports, perpendicular to its lateral railing, an electrical cabinet thus accessible from this platform, the driving cabin coming, in folded transport position, also be placed against said electrical cabinet, so that the side glazed portion of the cabin is also protected.
  • the invention also relates, as such, to a tower crane comprising a foldable cab-pivot unit, as defined above.
  • the pivot 1 is intended to be fixed to the top of the mast (not shown) of a tower crane.
  • the upper mast element 2, orientable on the pivot 1, is provided to support the boom (not shown) of the crane.
  • the pivoting mounting of the cabin 5 around the vertical axis 6 relative to the upper mast element 2 is achieved by a double hinge.
  • This hinge comprises, on the side of the mast element 2, a triangulated upper support 7, welded to an upper frame 8 of the mast element 2, and a triangulated lower support 9, welded on the base of the element of mast 2.
  • the hinge also comprises, on the side of the cabin 5, an upper support 10 welded to a vertical beam 11 of the supporting structure 12 of the cabin 5, towards the top of this supporting structure 12, and a lower support 13, welded to the vertical beam 11 of the supporting structure 12 of the cabin 5, towards the base of this supporting structure 12.
  • the hinge comprises two vertical axes, an upper axis 14 hingably connecting the two upper supports 8 and 10 , and a lower axis 15 hingably connecting the two lower supports 9 and 13.
  • the platform 4 which allows access to the driving cabin 5, comprises a side rail 16, which extends along one of its outer edges 17.
  • This platform 4 also supports an electrical cabinet 18, which extends along its outer edge 19, perpendicular to the edge 17.
  • the platform 4 comprises, on its outer edge 17, two double corner boxes 20, 21, provided to receive, removably, the two legs of the uprights 22 of the railing 16 which has two fixing positions.
  • the corner boxes 20 make it possible to fix the guardrail 16 in a vertical orientation.
  • the other corner boxes 21 make it possible to fix the same guardrail 16 in an oblique orientation, projecting outwards with respect to the edge 17 of the platform 4. Pins ensure the securing of the fixing of the guardrail 16, to avoid any accidental release from corner boxes 20 or 21.
  • the driving cabin 5 can be brought into a service position (FIGS. 1 and 2) or in a folded transport position (FIG. 3), the passage of a position to the other being done manually, by a rotation of 90 ° around the vertical axis 6, in one direction or the other - see the arrows F1 and F2 of Figure 1.
  • the driving cabin 5 is situated in the extension of the access platform 4, in front of the upper mast element 2.
  • the lateral guardrail 16, then fixed vertically on the outer edge 17 of the platform 4, is located in the extension of a side face 23 of the cabin 5.
  • the platform 4 and access to the cabin 5, the rear face 24 of the cabin 5 being provided with a door 25 which opens towards the platform 4.
  • the cabin 5 is thus brought above the platform 4 (and no longer in front of this platform 4), which considerably reduces the size of the cabin-pivot unit.
  • the driver's cab 5 is locked, in its folded transport position, by a lantern tensioner 31 mounted between the top of the mast member 2, on the one hand, and the top of the support structure 12 of the cabin 5, on the other hand.
  • the action of the tensioner 31 presses the base of the cabin 5 against a rubber stop 35 ( Figure 6), fixed on the structure of the platform 4.
  • the lantern tensioner 31 is placed in a storage position, indicated (by a simple axis) in phantom.
  • the lateral guardrail 16 is then fixed in its oblique orientation on the outer edge 17 of the platform 4, so as to be placed in front of the front face 32 of the cabin 5, taking into account the rounded shape of this front face 32.
  • the guardrail 16 thus ensures the protection of the front face 32 of the cabin 5, in particular of its lower glass portion 33, while the electrical cabinet 18 protects the lateral face 23 of the cabin 5, in particular its lateral glazed portion 34.
  • the entire cabin-pivot unit is pre-wired electrically, so that no electrical connection operation is to be performed at the time of its setting in service position, which contributes to the simplicity and speed of the setting implemented.
  • the cab-pivot unit described above, is applicable to tower cranes with "suspended" cab, of any configuration.
