Definitions

  • the present invention relates to a fall-protection counterweight apparatus for counterbalancing the weight of a user of a fall-protection element, in particular a fall-protection element of the type comprising a mast.
  • the counterweight apparatus is of the type comprising a mast receiving module for housing the mast of the fall-protection element, and a base module provided with a plurality of support legs for ensuring the stable support of the counterweight apparatus on a surface, either on a terrain, the floor slab of a building under construction, etc.
  • Document GB2330169-A discloses a deadweight anchor for use as a safety anchor to support a horizontal lifeline for workers on flat-roofed buildings in the event of a fall, comprising two deformable members in the form of strips or planks orthogonally disposed. The ends of each deformable member are connected by means locking members to weights and a pedestal with a point of attachment to the user's rope is provided at the upper deformable member, the pedestal being joined to the other member by means of a threaded shank.
  • the force applied to the deadweight anchor as a result of a fall causes the deformable members to buckle and absorb some of the energy of the fall and the anchor moves a distance along the roof surface.
  • an individual fall-protection device is the one described in patent document EP1400642-B1 , particularly indicated for work on horizontal surfaces in construction works, in which the anchoring means are made up of an anchoring element, suitable for being inserted into a mass of concrete or mortar in a fluid state, and remaining solidified to the same after the setting or hardening of said mass.
  • the safety device is essentially characterised in that the attachment means are made up of a mast, removably coupled at its lower part to said anchoring element with the possibility of pivoting on its vertical axis, and attached, at its upper part, to the upper end of a rope which, at its lower end is linked to the mentioned fastening means, the rope being able to rotate with respect to the vertical axis of the mast, such that the operator is firmly fastened with the possibility of moving freely within an essentially circular field of action, around said vertical axis.
  • the anchoring element is a sleeve which receives in its interior the lower end of the mast with the possibility of pivoting on its vertical axis.
  • the attachment means further comprise an upper rotating member, attached to the mast, with the possibility of rotating with respect to the latter on its vertical axis.
  • said upper rotating member comprises a rotating jib into the free end of which the upper end of the rope is fixed.
  • the device may comprise an arm fitted with a fixed or movable compensating ballast at the opposite end of the rotating jib.
  • the rope comprises energy absorbing means, adapted for preventing the operator from suffering an impact by the jerking of the rope in the event of an accidental fall.
  • FIG. 1 Another device example is the one described in patent application EP3002044-A1 , which discloses a fall-protection system for securely coupling a user to a support structure.
  • This fall-protection system comprises a mast arranged to be vertically mounted in a state of use, having a top end and a base end; a user connection assembly; and a tether connector; wherein the mast comprises a structure connection portion, in which the mast is arranged to be removably connected to the support structure, and an energy absorbing deformation portion positioned closer to the top end than the structure connection portion.
  • One of the figures of document EP3002044-A1 illustrates how the fall-protection system is mounted in a type of support structure, which consists of a transportable anchor, which in short comprises a frame structure and counterweights, such as concrete weights, placed in the frame structure.
  • the transportable anchor further has an anchoring member which receives the structure connection portion of the mast of the protection system.
  • the transportable anchor is used in situations when a user is going to work on the roof of a lorry.
  • Document ES2639164-T3 describes a fall-protection counterweight apparatus for counterbalancing the weight of a user.
  • the apparatus has a top module having a plurality of horizontal members that support a plurality of top leg couplers and a mast coupler; a base module having a plurality of horizontal members, each of the horizontal members extending between a pair of base leg couplers; a stowage module coupled to the base module and arranged within an interior region coplanar with the horizontal members of the base module; and a plurality of legs.
  • the top module In a fall-protection mode adapted for operation, the top module is spaced apart from the base module by the plurality of legs, each of the legs being releasably coupled at opposing ends to one of the top leg couplers and one of the base leg couplers. In contrast, in a low profile mode adapted for storage, the top module is directly coupled to the base module coupled by one of the corresponding top base leg couplers, each of the legs arranged within the stowage module.
