Definitions

  • a winch hoist of the type specified is fixed to a metallic pole support, such as a vertical tubular element of pipe scaffolding (on a building site), or a vertical tubular element interposed and fixed between two decks of a building structure.
  • a winch hoist of the type specified, according to known art, is shown in figure 1 accompanying this description.
  • a winch hoist of the type specified can weigh on average between 50 kg and 60 kg and is fixed to the respective metallic pole support at a height of around 2m from the supporting plane on which the workers who need to use the hoist are standing. Therefore, to mount the hoist, an operator needs to manually lift and support said hoist at the indicated height, until such time as the operations required to fix it to said pole support are completed, operations that are carried out by another operator.
  • a system of support struts needs to be provided for mounting said hoist. Therefore, at least two operators are required to mount said winch hoist, otherwise support means need to be provided beforehand.
  • Document no. GB2 087 346 A describes an apparatus for mounting and dismounting a swing winch hoist on a pole support, comprising:
  • the afore-mentioned known apparatus comprises winch means driven by a motor, which makes the structure complex and difficult to maintain, as well as costly.
  • the present invention intends to provide a solution wherein a manual winch hoist can be used.
  • an aim of the present invention is to provide an apparatus for mounting a swing wihch hoist on a pole support, which will make it possible to considerably reduce physical fatigue and simplify the work, thereby enabling a single operator to carry out all the required operations in safe conditions.
  • a further aim of the invention is to provide an apparatus for mounting a swing winch hoist on a pole support, which has a simplified structure, and is safe, reliable and easy to use.
  • Yet another aim of the present invention is to provide an apparatus for mounting a swing winch hoist on a pole support, that enables a single operator to carry out the required mounting operations, simply and safely.
  • the present invention provides an apparatus for mounting and dismounting a swing winch hoist on a pole support, the essential characteristic of which is the subject of claim number 1.
  • said apparatus is characterized in that said metal supporting overhanging arm comprises detachable fastening means with respect to said pole support, which include:
  • the apparatus for mounting and dismounting a swing winch hoist on a pole support is indicated as a whole by the number 10.
  • said metal supporting overhanging arm 11 comprises detachable fastening means 14 with respect to said pole support P, which include:
  • said detachable fastening member 15 consists of a fastening pin 15.1 with a plurality of transversal through-holes, which is arranged passing through a pair of corresponding through-holes, provided in the opposite prongs of said fork 14.1 and aligned along a transversal axis.
  • the pole support P has a plurality of pairs of diametrical through-holes (not visible in figure 2 ).
  • Said metal sleeve 16 in turn, has a corresponding pair of diametrical through-holes, axially aligned with a corresponding pair of diametrical holes of said pole P.
  • a fastening pin 16.1 is arranged passing through said two pairs of diametrically aligned corresponding holes of said sleeve 16 and of said pole support P, thereby assuring the detachable fastening.
  • said supporting overhanging arm 11 is formed of a substantially upside-down, "U"-shaped metal profile 11.3, comprising two substantially vertical sides 11.4 a substantially horizontal bridge 11.5 between said sides.
  • Said first end zone 11.1 of said arm 11 shaped as a fork 14.1 is formed of respective free portions of said sides 11.4 extended beyond said bridge 11.5.
  • a transverse spacer member 17 is fixed between said sides 11.4, distal from said bridge 11.5 and shaped to be partially coupled to said pole support P underneath said first end zone 11.1.
  • a plurality of further transverse spacers 17.1 are fixed between side sides 11.4, to stiffen the structure of said supporting arm 11.
  • supporting overhanging arm 11 comprises a substantially "L"-shaped side bracket 18, provided at an extended free portion of one of said sides 11.4 and on which a substantially "U”-shaped rigid metal bracket 18.1 is fixed, the free branches of which rotationally support the axis of said drum 12.1.
  • said lifting rope (not illustrated) is formed of a sturdy ribbon.
  • said guide roller 13 is rotationally supported externally to the side 11.4 of said supporting arm 11, on which said substantially "L"-shaped bracket 18 is provided.
  • said apparatus 10 for mounting a swing winch hoist on a pole support makes it possible to considerably reduce physical fatigue and simplify the work, thereby enabling a single operator to carry out all the required operations in safe conditions.
  • said apparatus 10 as described has a simplified structure, and is safe, reliable and easy to use.
  • said apparatus 10 as mentioned enables a single operator to carry out all the operations required for the above-mentioned mounting, in a safe, simple manner.
  • the present invention enables the aims listed in the introduction to be achieved simply and advantageously.
