Definitions

  • the present invention is related to tower cranes that are used primarily in construction sites, proposing a boom or counter-pen structure for cranes without straps, with an embodiment that provides technical and economic advantages over the solutions currently used in construction. formation of these structures.
  • a tower crane is a lifting device of discontinuous operation, intended to lift and distribute in the space suspended loads of a hook or any other means of apprehension.
  • the most common use of these cranes is in construction sites, being their temporary installation, so they are usually subjected to frequent assemblies, disassembly and transfers.
  • This type of crane is made up of a series of fundamental structural parts, which are: base, tower, turntable, boom, backlight, counterweight, cusp, ballast, boom carriage and load seizure element.
  • the base is the element that supports the tower of the crane and the ballast necessary to ensure stability.
  • the tower is a vertical structure comprised between the base and the top of the crane.
  • the turntable is an adjustable structure thanks to a rotating crown located at the top of the tower.
  • the boom is a structural component capable of supporting the lifting loads in the corresponding ranges.
  • the counter-pen is a structural component that supports the crane's counterweight.
  • the counterweight is a mass that is held in the counter-pen and whose function is to counteract and balance part of the actions of the payload and some parts of the crane, in operation.
  • the cusp is a structural element that integrates the rotating part and is capable of supporting and transmitting the stresses coming from the structures of the pen and the counter-pen.
  • the ballast is a mass that is held in the base, with the function of contributing to the stability of the crane's structural assembly.
  • the pen carriage is a carrier device for the load-seizing organ, being movable along the boom.
  • the apprehension organ is a device that has the function of suspending the loads, being able to take the form of a hook, spoon, electromagnet, etc., depending on the type of loads to be handled with the crane.
  • two main versions of tower cranes are known, which are cranes with braces and cranes without braces; using tower cranes with braces a large cusp, to which tension braces are attached that help support part of the weight and part of the load transmitted by the boom and counter-pen structures; while towerless tower cranes employ a cusp smaller than the equivalent of tower cranes with braces.
  • a boom and / or counter-pen structure of a tower crane without braces is proposed, with which characteristics are obtained that provide advantages for the formation of cranes of this type of great capacity and ease of transport.
  • This structure object of the invention is formed by partial sections that allow the composition of a pen or a counter-pen by joining successive similar sections, each section comprising a lattice bottom that determines at the ends some couplings destined for the union with other consecutive sections, and an upper lattice formed by panels that are arranged articulated or removable on the lower lattice, incorporating these panels on the opposite edge of the union with the lower lattice links for the union between them and the union in turn with other consecutive sections; determining the lower lattice a truncated pyramidal formation, while the upper lattice determines a triangular profile formation on the upper base of the lower lattice.
  • a structure is thus obtained in whose sections the panels of the upper lattice can be disassembled or folded on the sides of the lower lattice, whereby said component sections of the structure can be transported in containers of small dimensions, for once at the destination , by deploying or assembling the panels of the upper structure, form the sections of the structure with a large section and, consequently, of great resistance.
  • the recommended structure is therefore very advantageous for the formation of feathers and counter-feathers of tower cranes of great capacity without straps, acquiring its own life and preferential character for said application.

  • Said structure object of the invention has the purpose of allowing the construction of tower cranes of this type with a capacity similar to that of the large tower cranes provided with tie rod (8), as shown in Figure 1, determining the boom ( 1) and the counter-pen (2) with a structural resistance that allows to eliminate the braces (8) and, consequently, reduce the cusp (3), and at the same time with an embodiment that allows a folding or disassembly for transport in conventional containers .

  • Each partial section of said structure object of the invention ( Figures 3 and 4) comprises a lower lattice (9) determined according to a truncated pyramid formation, and an upper lattice (10) that is arranged by determining a triangular profile formation on said lower structure ( 9).
  • the lower lattice (9) is formed by a fixed structural assembly, having at the ends some couplings (11) for joining with other consecutive sections; while the upper lattice (10) is composed of lateral panels (12), which are joined by an edge to the upper part of the lower lattice (9) by means of couplings (13), which can be articulated or removable , while on the other edge said panels (12) have other couplings (14), for the union between them and with other consecutive sections.
  • the panels (12) of the upper lattice (10) can be removed from the lower lattice (9) or collapsed on the sides of the lattice, in a simple and fast way, which allows transporting the component sections of the Conventional container structure of small size, thus facilitating the transport of cranes between different locations of using them.
