Definitions

  • the present invention relates, in general, to the field of tower cranes, such as those used on construction sites. building construction. More particularly, this invention is interested tower cranes with "suspended" driving cabins and, even more specifically, it relates to a folding cabin-pivot unit for a crane to tower of this type.
  • the "suspended" driver's cab can be associated with the pivot located at the top of the mast, and serving for the orientation of the boom of the crane, to constitute a set designated as "cabin-pivot unit".
  • cab-pivot unit An example of a cab-pivot unit can be found in the document FR 2565950 A; the cabin here occupies a fixed position relative to the arrow crane, the cabin-pivot unit is not planned collapsible.
  • the present invention aims to avoid all of these disadvantages, by providing an improved cabin-pivot unit which, while retaining a simple and economical structure, allows in particular to achieve quick and easy way of bringing the cab into the service position, while allowing a folding of the cabin in minimum space and without addition protection elements.
  • the driver's cab is hinged to the mast element by a double hinge vertical section comprising, on the side of the mast element, an upper support and a lower bracket respectively attached to the top and bottom of the element of mast, and, on the cabin side, an upper support and a lower support fixed respectively on the top and on the base of the carrying structure of the cabin, the upper supports and the lower supports being connected by vertical axes, respectively upper and lower.
  • the means of fixing the lateral guardrail on the platform access to the cabin may include, on an outer edge of the platform, double corner boxes receiving the feet of the uprights of the guardrail, fixing, depending on the corner box used, the vertical orientation or oblique these amounts, so the rail.
  • the cabin access platform still supports advantageously, perpendicular to its lateral railing, a cabinet electric and accessible from this platform, the driver's cab coming, in folded transport position, to also be placed against said cabinet electrical system, so that the side glass part of the cab is also protected.
  • the invention also has as its object, as such, 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 (no represented) 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 made 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 element of mast 2, and a triangulated lower support 9, welded to the base of the mast element 2.
  • the hinge also comprises, on the side of the cabin 5, a top support 10 welded to a vertical beam 11 of the carrier 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 support structure 12 of the cabin 5, towards the base of this supporting structure 12.
  • the hinge comprises two axes vertical, an upper axis 14 connecting in an articulated manner the two supports 8 and 10, and a lower axis 15 articulately connecting the two lower supports 9 and 13.
  • the platform 4 which allows access to the driving cabin 5, has a side rail 16, which extends along one of its edges 17. This platform 4 also supports an electrical cabinet 18, which extends along its outer edge 19, perpendicular to the edge 17.
  • platform 4 comprises, on its outer edge 17, two double corner boxes 20, 21, provided to receive, removably, both feet of the uprights 22 of the guardrail 16, which has two fixing positions.
  • Corner boxes 20 allow to fix the guardrail 16 in a vertical orientation.
  • Others corner boxes 21 make it possible to fix the same railing 16 in an orientation oblique, projecting outwards with respect to the edge 17 of the platform 4. Pins ensure the securing of the attachment of the guardrail 16, to avoid any accidental release from the corner boxes 20 or 21.
  • the cabin 5 can be brought into a service position (FIGS. 1 and 2) or in a folded transport position (FIG. 3), the transition from one position to the other is done manually, by a 90 ° rotation around the axis vertical 6, in one direction or the other - see arrows F1 and F2 in the figure 1.
  • the driver's cab 5 located in the extension of the access platform 4, in front of the element 2.
  • the side rail 16, then fixed vertically on the mast outer edge 17 of the platform 4, is in the extension of a face 23 of the cabin 5.
  • the platform 4 thus gives access to the cabin 5, the rear face 24 of this cabin 5 being provided with a door 25 which opens towards platform 4.
  • the cabin 5 is thus brought over the platform 4 (and no longer ahead of this platform 4), which significantly 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 element 2, on the one hand, and the top of the carrier structure 12 of the cabin 5, on the other hand.
  • the action of the tensioner 31 press the base of the cabin 5 against a rubber stop 35 (FIG. 6), attached to the platform structure 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 orientation oblique on the outer edge 17 of the platform 4, so as to be placed in front of the front face 32 of cabin 5, taking into account the rounded shape of this front face 32.
  • the guardrail 16 thus ensures the protection of the face before 32 of the cabin 5, in particular of its lower glass portion 33, while that the electrical cabinet 18 protects the lateral face 23 of the cabin 5, in particularly its side glass part 34.
  • the entire cab-pivot unit is electrically pre-wired, so no electrical connection operation is to be performed at the time of its setting in service position, which contributes to simplicity and speed implementation.
  • the cab-pivot unit described above, is applicable to tower with "suspended" driver's cab, of any configuration.
