Definitions

  • the present invention relates to a gripping and a lifting device of slabs.
  • the invention relates to a gripping and a lifting device of heavy slabs, such as for example marble or stone slabs, or slabs made of another material, for example for use in the stone laying sector.
  • hoists are used for moving slabs which comprise a hoist that can rest on a ground surface, which comprises a gripping organ of a slab which can be translated vertically by the hoist, for example by rotating a crank or a motorized device, for example screw device, between a lowered position and at least a raised position.
  • the gripping organs generally comprise a pair of lower arms spaced from one another and defining a horizontal lower rest plane for the lower surface of the slab located by a side (i.e. with the lie plane substantially vertical) and a vertically mobile upper arm, along an upright solidly constrained to the pair of lower arms, distancingly and nearingly from and to the lower rest plane.
  • the upper arm is constrainable to the upright, by means of threaded blocking organs, so that they can be rested on the upper surface of the slab (opposite the lower surface) and fixed in the rest position.
  • the lower arms are fixed to a common cross member, which is associated to a vertical slide of the hoist which enables vertical movement of the gripping organ.
  • the slab can be interposed between the lower arms and the upper arm and retained between them during the vertical movement imparted by the hoist to the gripping organ.
  • fixing pins on the vertical wall, which pins project from the wall, for example at least two lower and at least one upper pins.
  • the slab must therefore be positioned, using the hoist, resting on the lower fixing pins, so that it is vertically interposed between the lower fixing pins and the upper fixing pin.
  • blocking organs for example washers or stakes which engage on the pins so as to project radially therefrom.
  • this operation involves those originating from the use of personnel in stressful situations and forced often to work in precarious situations of equilibrium, high-up in relation to the ground surface and in environments that are not comfortable, and the risk of the slab falling vertically in the passage thereof from resting on the lower arms to resting on the lower fixing pins, with all the drawbacks that entails.
  • An aim of the present invention is to obviate the above-mentioned drawbacks in the prior art, with a solution that is simple, rational and, for example, relatively inexpensive.
  • the invention relates to a gripping and lifting device of slabs which comprises a support cross member able to support at least a gripping organ of a slab, in which the gripping organ of the slab comprises at least a bearing body inferiorly hung on the support cross member and provided with a support shelf defining a rest plane for a lower edge of the slab, and a gripping body provided with a gripping hook of an upper edge of the slab and slidably associated to the bearing body from a neared position to the support shelf to a distanced position therefrom, in opposition to elastic pushing means.
  • the slab can be manoeuvred and installed, even when it is a heavy and awkward slab that is to be installed in positions and locations that are not easy, in perfect safety while enabling the slab to be solidly constrained to the gripping organ during all the operations of movement thereof up to the secure fixing thereof to the wall.
  • the pushing means can comprise at least a spring.
  • the gripping organ is safe and at the same time economical and fast to assemble.
  • the support shelf exhibits a substantially C-shaped conformation having a concavity facing upwards and is able to envelop a portion of the lower edge and at least a portion of a face adjacent to the lower edge of the slab.
  • the gripping hook advantageously exhibits a substantially C-shaped conformation with a concavity facing downwards and is able to envelop a portion of the upper edge and at least a portion of a face adjacent to the upper edge of the slab.
  • the slab is solidly engaged between the support shelf and the gripping hook without any risk of accidental disengaging therefrom during the movement thereof.
  • the bearing body can advantageously be hung from the support cross member by means of at least a hooking element, for example a carabiner hook.
  • the bearing body is afforded several degrees of freedom which facilitate activation thereof by the operator, who in any case can manoeuvre the heavy slab from a raised position with respect thereto and therefore in conditions of complete safety.
  • the gripping organ is movably associated along a longitudinal axis of the support cross member.
  • the slab can easily be gripped by the gripping organ and always in the most advantageous position in terms of leverage and equilibrium of the centre of gravity of the device.
  • the support shelf advantageously comprises at least a fixed portion and at least a mobile portion able to be moved along the longitudinal axis of the fixed portion and blockable with respect to the fixed portion by releasable fixing means, the gripping organ being inferiorly hung from the mobile portion such as to be mobile along the longitudinal axis of the cross member.
  • the support cross member is fixed to at least a carriage that is mobile on a longitudinal guide, i.e. a guide bar, that is substantially perpendicular to a longitudinal axis of the support cross member.
  • the slab can be neared to and distanced, while maintaining the same height, to the wall to which it is to be fixed, while remaining solidly gripped by the gripping organ.
  • At least two of the gripping organs, distanced from one another, can advantageously be hung from the support cross member, along the longitudinal axis of the support shelf.
  • a lifting group of slabs which comprises a gripping and lifting device, according to any one of the preceding claims, wherein the hoist is able to move the gripping and raising device in a vertical direction.

  • the slab 20 must be lifted up to the height at which the lower edge 23 thereof is substantially coplanar (slightly higher) than the plane defined by the lower pins 61.
  • the slab 20 in the vertical position is brought substantially into a position superposed in plan view on the external axial part of the lower pins 61 (in which the lower edge 23 of the slab 20 is maintained at a minimum distance from the lower pins and the upper edge 24 is maintained, inferiorly of the upper pin 61, at a minimum distance therefrom, in this case minimum distance being taken to mean a distance not greater than the distance between the external jacket of the pin 61 and the most off-centre position of the broadened head 62).
  • the hoist 11 is activated so as to lower the slab 20, for example by an amount equal to the minimum distance mentioned above, down to when it rests on the lower pins 61, the plate 20 can be freed from the clamping action of the gripping organs 32.
  • the gripping body 323 is first brought into a distanced position from the support shelf 322, so as to free the upper edge 24 of the slab 20 from the gripping hook 24 and, thereafter, by pulling the bearing body 321 downwards the lower edge 23 of the slab 20 is freed from the support shelf 322, thus enabling distancing of the lifting group 10 and definitively securing the broadened heads 62 on the pins 61.
