Definitions

  • the invention relates to a collapsible and relocatable small crane for use on construction sites with a plug-in into a base frame and rotatably mounted in the base frame at two bearing points, the base frame having lateral, provided with longitudinal rollers support feet, which are arranged on a receiving tube for the mast and a boom arranged at the upper end of the mast, which carries a load suspension device movable in its longitudinal direction and with a device for receiving a counterweight.
  • the purpose of the invention is to simplify the physically demanding, time-consuming and inefficient processing of large-format bricks on the construction site.
  • the large-format stones with weights of up to 40 kg are in most cases placed by the masons by hand on the wall crown and bricked up.
  • DE-GM 90 10 221 describes a small crane with the features specified above. Although this small crane can be dismantled and thus solves the problem of using the crane only with the help of large cranes, it still has a few disadvantages, which are described below:
  • This well-known mini crane has e.g. a continuous boom, the part facing away from the load side is used to brace and stabilize the system. On the one hand, this long boom hinders the transport stability of the device, which runs counter to the goal of dismantling.
  • this boom is also so heavy that it cannot be transported by two men if it is structurally correct.
  • the counterweight basket of this crane hangs so low that when the crane is pivoted, the basket swings into the body area of people and there is a risk of injury.
  • the invention is therefore based on the object, first of all to improve the above-described condition on the construction sites in favor of the humanization of the work areas and also to achieve significant advantages over the existing and introduced and described small cranes in which the crane, with the simplest construction, offers a maximum of safety and Maintains functionality and manages with the smallest possible components and the lowest weights, and easy transportability is also achieved with regard to the spatial expansion.
  • the basic idea of the invention is to construct a small crane so that the boom does not protrude beyond the pivot point on the mast, which makes it particularly short and light and the device for receiving the counterweight is designed so that the counterweight is above the head height can be arranged by people, the boom and counterweight are connected via a simply constructed guy device, so that the forces of the boom can be easily introduced into the receiving arm.
  • the small crane according to the invention is designed so that it meets the standards and regulations of the building trade association.
  • the small crane according to the invention has the additional advantage that it can be constructed in a simple manner in different types, which for example start from the same base frame and have different boom lengths and are designed for different lifting forces.
  • an entire crane system can consist of a base frame and several jibs, which allows great flexibility in the use of the small crane.
  • the small crane according to the invention is designed in such a way that no special tools are required for the construction. Rather, simple plug-in connections and bolts can be used, which are attached captively by a safety chain. This simplifies the set-up, since no time has to be spent searching for small accessories.
  • the small crane shown in its entirety in FIG. 1 has a mast 1 which is inserted into a receiving tube 16 which, together with support feet 17 arranged thereon and having swivel castors 18 on its underside, forms a base frame.
  • a tubular receptacle 2 into which the inner end 14.2 of a receiving arm 14 is inserted, at the outer end of which a counterweight 15 is suspended via a plate-like suspension 14.1.
  • the counterweight 15 is designed as a so-called tractor weight, which has a recess 15.1, by means of which it is suspended in the suspension 14.1.
  • the outer end of the receiving arm 14 is after kinked above, whereby it is achieved that the counterweight 15 is above the head height of the operators.
  • a square tube 31, on which a cable winch 12 is arranged, the function of which is explained below, is slipped onto the inner end of the receiving arm 14, which is designed as a square, before being inserted into the receptacle 2.
  • a boom 6 which is articulated to the mast 1 at the fastening point 5 and extends from this point in only one direction.
  • the boom 6 carries a trolley 7 (see FIG. 5) which can be moved along its longitudinal direction on a T-rail 6.1 and on which a chain hoist 8 and an operating device 9 are suspended.
  • the forces acting on the boom 6 are derived via a guying device which has a guy linkage 10 which engages approximately in the middle of the boom and which is connected to a deflection frame 11.
  • the deflection frame 11 has a substantially triangular shape in a side view, the tip of the triangle lying in the attachment point 5 of the boom, which is connected to the bracing linkage 10 at one corner point and the other corner point is connected to the receiving arm 14 for the counterweight 15 via a guy chain 13 is. Furthermore, the deflection frame 11 is connected to the cable winch 12 in the vicinity of the last-mentioned corner via a cable 12.1.
  • the upper part 1a of the mast consists of a thin-walled tube material than the lower part 1b of the mast, which is inserted into the receiving tube 16. This ensures that the entire mast 1 becomes lighter, which serves for portability, but nevertheless the high absorption forces which act on the mast in the lower region are absorbed by the wall reinforcement located there.
  • a bearing 4 is arranged in a two-part bearing shell, the upper bearing shell part 19 being welded to the lower part of the mast 1b.
  • the bearing shell lower part 20 lies on a flange 24 arranged at the upper end of the receiving tube 16.
  • the bearing shell 19-20 serves to accommodate a large-dimensioned tapered roller bearing 21, via which the forces acting radially and axially on the mast can be absorbed.
  • the two bearing shells 19 and 20 are connected at the opposite outer edges by means of a felt strip 22 which is inserted into an annular groove made in the outer edge and seals the interior of the bearing shell 19-20.
  • a mounting ring 28 is slid onto the lower part 1b of the mast below the bearing shell 19-20 and screwed onto the mast to support the lower bearing shell part 20 before assembly.
  • a bearing receiving ring 23 is welded onto the flange 24 at the upper end of the receiving tube 16, which ensures the centering of the bearing during assembly.
  • a bearing journal 25 is welded, which engages in a bore which is arranged coaxially to the central axis of the mast 1 in a flange 26 arranged at the lower end of the receiving tube 16.
  • Fig. 3 shows a detail in the region of a fastening point of a support leg 17 on the receiving tube 16.
  • the receiving tabs 27 are welded to the receiving tube 16 so that the tabs are arranged opposite a receiving block 29 connected to the supporting leg 17, a bolt through the receiving tabs 27 and the receiving block 29 is passed in the horizontal direction.
  • the outer end of the receiving arm 14 has a shackle holder 33, to which the guy chain 13 is fastened via a chain tensioner 32.
  • the power supply cable 35 is suspended on the guide rail 6.1 of the arm 6, by means of simple trapezoidal wire clips 34, the open side of which is pushed over the T-profile of the guide rail 6.1, on which the trolley 7 runs.
  • a snap hook 36 is in each case suspended, which in turn is connected to the cable 35 by means of a loop clamp 37, the cable 35 being still protected by means of a hose piece 38 placed in between.
  • the necessary for the power supply socket and the main switch can be attached to the small crane in a manner not shown and known per se by attaching a permanent magnet in a disc-shaped form to the socket on the back of the switch, which is designed as a common component, with the aid of which the component can be magnetically attached to the small crane.
  • the small crane shown in FIGS. 1 to 6 is built up by first placing the receiving tube 16 on the floor and suspending the support feet 17 in the receiving tabs 27 and fastening them there with the bolts 30. First, three support feet 17 are attached to the receiving tube 16. Then the mast 1 is inserted into the receiving tube 16 and then the boom 6 is attached to the mast at the fastening point 5 by bolts. Then the deflection frame 11 is fixed to the mast head by bolts and the guy linkage 10 is connected to the deflection frame 11.
  • the small crane can then be erected by pushing the boom and simultaneously loading one of the support feet 17 until the mast 1 is perpendicular to the base. Then the fourth support leg 17 is attached to the receiving tube 16 in the manner described above, so that the small crane receives the necessary stability. Then the mounting arm 14 is mounted.
  • the tube 31 carrying the cable winch is first pushed on and then the end 14.2 is inserted into the receptacle 2, so that the parts are firmly connected to one another without screw connections or other expenditure.
  • the counterweight 15 in the receiving arm 14 By hanging the counterweight 15 in the receiving arm 14, the whole is loaded and thereby additionally fastened.
  • the boom 6 can now be erected by actuating the cable winch 12, the guy chain 13 can be hooked in and fine-tuned by means of the chain tensioner 32. Before the trolley 6 was folded down, the trolley 7 and the chain hoist 8 were attached to the boom 6 and the cable 35 was arranged in the manner described with reference to FIGS. 5 and 6.
  • FIGS. 7 to 11 An embodiment of a small crane is shown in FIGS. 7 to 11, which differs in some details from the previously described embodiment.
  • FIGS. 7 to 11 components that are identical to components from FIGS. 1 to 6 are identified by the same reference number.
  • FIG. 7 and 8 show that in this embodiment the receiving arm 14 'is not angled, but is straight.
  • a frame 14.3' is arranged with plate-like suspension elements 14.1 ', in which the counterweights 15' are suspended in two rows one above the other. With this shape it is possible to increase the static properties of the small crane by using a larger number of counterweights.
  • the winch 12 'already mentioned is arranged directly fixed on the receiving arm 14', which saves a further individual part.
  • a cable block 40 with a cable pulley 61 is connected between the turnbuckle 13.1 'and the guy chain 13' and is connected to the turnbuckle 13.1 'via a cabin hook 41.
  • the rope 12.1 'coming from the winch 12' is guided around the rope pulley 61 and its free end is connected via a fastening eye 12.2 'to an eyelet 39.3 fixedly arranged on the receiving arm 14'. This guidance of the rope 12.1 'leads to a reduction in the forces which occur when the boom is raised, since the rope block 40 acts as a pulley block, which halves the forces which occur.
  • the tubular receptacle 2 arranged on the mast 1 is held by an upper support strut 3.1 and a lower support strut 3.2.
  • cross connections 43.1, 43.2, 43.3 are used between the mast 1 and the upper support strut 3.1, which can be used as ladder rungs.
  • the boom which is denoted overall by 6 ', can be composed of two parts.
  • the inner part 6.2 is connected to the mast 1 via a connecting element 6.4, while the outer part 6.3 is connected to the inner part 6.2 via a connection, which is shown in more detail in FIGS. 10 and 11.
  • the inner base part 6.2 of the boom has on its underside a T-beam 44 which is connected via braces 60 or 60 'to pipe supports 42 or 42' on the top side, so that the cross-section of the boom, as shown in FIG. 11 can be seen, essentially has a triangular shape.
  • the outer part 6.3 serving as a cantilever extension is designed in an analogous manner. It has a T-beam 45 on its underside, which is suspended from two tube supports 46 on the upper side via struts 62.
  • a flat steel 47 is welded in the area of the connection of the two parts of the bracket to the underside 44.1 of the T-beam 44, at the free end of which there is a bore 48 designed as an elongated hole.
  • a flat steel piece 49 is welded, which is designed so that it when assembling of the two parts 6.2 and 6.3 of the boom engages in the bore 48, so that a positive connection is formed at this point.
  • the two pipe supports 42 and 42 'and 46 are connected to one another via an insertion sleeve 51, the connection being secured by means of plug-in bolts 50.
  • the guy rod 10 (see FIG. 1) is connected to an extension 10.1 'via a connecting strap 52, the connection also being secured by insert bolts. All insert bolts are captively attached.
  • the shape of the flat steel pieces 47 and 49 arranged on the undersides 44.1 and 45.1 of the T-beams 44 and 45 ensures perfect functioning of the trolley running along the boom (see FIGS. 1 and 5).
  • the assembly aid is designed as a triangular linkage 53 which is attached at one end to a bracket 54 which is arranged on the upper support strut 3.1 of the small crane. Fastening is also done here by means of a plug pin 55. Wheels 59 are located on the tip of the triangular assembly aid 53 sitting on the floor. Furthermore, a chain hoist 62.3, which is driven by an electric motor, can be suspended in an eyelet 56 arranged on the assembly aid 53. The chain 62.1 of the chain hoist is guided over a first deflection roller arranged between the wheels 59 and over a second deflection roller 57 which is arranged at one end of a chain 58, the other end of which at the lower end of the receiving tube 16 of the small crane is attached. The other end of the chain 62.1 is hooked onto the lower end of the receiving aid 53 in a manner not shown.
  • the chain 62.1 is pulled in by actuating the control switch 62.2 of the chain hoist 62.3.
  • the distance between the receiving tube 16 and the lower end of the receiving aid 53 is shortened and the crane is raised.
