Definitions

  • the present disclosure refers to a metal gantry for a lifting device suitable for the transport of materials in works. This disclosure is able to be applied when mounting a winch or a pulley on a window, balcony, between two "floor and ceiling” slabs, or even on a stairwell is intended, in order to raise or lower materials.
  • the present disclosure refers to a metal gantry for transporting materials in works.
  • a possible alternative of the present disclosure will be building a wooden structure, using beams, joists, screws and nails, to fix the winch or the pulley. However, it will always take at least two people to carry out this assembly, thus wasting time and money.
  • Another even bigger problem is that when there are only two people on the work site, and for some reason one of them has to be absent from the work site, either to get materials or any other situation and, meanwhile, it starts raining, it becomes very difficult to dismantle the structure. That happens because since it takes two people to dismantle the prior art structures, in such cases water often enters and causes some damage, especially when the floor is made of wood and is irreplaceable.
  • BRPI0505135A describes a portable combined crane, composed of a vertical column trolley, a cross beam and an electric hoist. Wherein the electric winch is arranged on the cross beam; a hook is arranged on the electric hoist.
  • the portable combined crane adopts a detachable combinable structure; a counterweight bearing structure which is arranged at the rear end of the cross beam; the vertical column trolley and the scale bearing structure are supported on the floor and the ceiling respectively.
  • the present disclosure refers to a metal gantry for a lifting device for transporting materials in works, when mounting a winch or a pulley on a window, balcony, between two "floor and ceiling” slabs, or even on a stairwell is intended, to raise or lower materials.
  • This structure was designed to be assembled between two Slabs (floor and ceiling), the structure is entirely metallic, being composed by: two bases, one for the floor and one for the ceiling, two round tubes, one entering inside the other, a male thread and a nut for adjusting the structure from floor to ceiling, a shaft and a washer, an arm in an Apollo rail with a length of one meter and twenty centimeters, where a trolley will slide wherein the winch or the pulley is fixed, two 125x25x14 3-knot eyes to connect to the tube and to the arm, one F1 Apollo rail, 50x08, 30x08, 30x05 iron bars, 12 rod, 45x3 square tube, two double power- 1 N.35 trolleys.
  • this structure was developed to be assembled between two slabs, firstly one should adjust the tubes between the slabs by raising the upper tube until it hits the top slab (ceiling) and then apply the shaft in the hole that best suits, the tubes must be upright, then tighten with the nut to create pressure between the slabs, after this operation just apply the arm with the two pivots, and it is ready to receive the sliding trolley with the winch or the pulley, the arm rotates from zero to one hundred and eighty degrees, being able to work in any of these positions.
  • the present embodiment describes a metal gantry for supporting a lifting device for transporting materials, comprising: a telescopic structure comprising an outer tube and an inner tube; an arm rotatably connected to the outer tube, for the displacement of the lifting device transverse to the telescopic structure; a nut for threading at the upper end of the outer tube; a shaft to hold the inner tube within the outer tube in said nut; wherein the outer tube comprises a base at the lower end for resting on a floor and a thread at the upper end; wherein the inner tube comprises a bearing for securing to the ceiling of a slab and a plurality of holes for fitting said shaft and holding the inner tube within the outer tube.
  • the metal gantry for supporting a lifting device comprising: a rail with a limit stop point on the rail; a trolley to slide in the rail and support the lifting device.
  • the arm comprises: a rail and a trolley to slide in the rail and support the lifting device.
  • the arm comprises: a lower connection point of the rail to the outer tube; an upper connection point of the arm to the outer tube wherein the connection points are connected to each other by a beam.
  • the arm further comprises a primary diagonal bar fixed between the upper point and a central point on the rail.
  • the arm comprises a supporting bar longitudinally extended along the rail between the central point and the limit stop point of the rail and further a secondary diagonal bar between the upper point and the limit stop point of the rail.
  • the limit stop point includes a ring and a screw-nut to allow the application of a pulley and to prevent the trolley from leaving the rail.
  • the nut comprises two side handles.
  • the arm is connected to the outer tube through an eye and a shaft at each of the lower and upper points.
  • the trolley comprises a handle.
  • the base is between 150 - 350 mm by 200 - 350 mm by 4-6 mm, preferably 250 mm by 250 mm by 5 mm.
  • the outer tube is between 1900 - 2500 mm by 60 - 80 mm by 2 - 4 mm, preferably 2000 mm by 70 mm by 3 mm.
  • the inner tube is between 1400 - 2000 mm by 50 - 70 mm by 2 - 4 mm, preferably 1500 mm by 60.3 mm by 2.9 mm.
  • the beam is between 200 - 400 mm by 20 - 40 mm by 7 - 10 mm, preferably 300 mm by 30 mm by 8 mm.
  • the primary diagonal bar is between 600 - 860 mm by 20 - 40 mm by 7 - 10 mm, preferably 650 mm by 30 mm by 8 mm.
  • the supporting bar is between 500 - 1120 mm by 40 - 60 mm by 7 - 10 mm, preferably 670 x 50 x 8 mm.
  • the secondary diagonal bar is between 1100 - 2000 mm by 20 - 40 mm by 7 - 10 mm, preferably 1200 mm by 30 mm by 8 mm.
  • the present embodiment further describes a method of applying a gantry for supporting a lifting device for transporting materials according to any one of the previous embodiments, comprising: joining said telescopic structure; adjusting the base to the floor and the bearing on the ceiling of a slab; holding the inner tube within the outer tube with the shaft; threading the nut and fitting the arm into the outer tube.
