Definitions

  • the present invention relates to a lifting apparatus having a capacity not exceeding 200 kg.
  • a vehicle such as a truck
  • a vehicle is used provided with a lifting apparatus of less than 200 kg capacity but which nevertheless changes the axle loading of the vehicle, which has to be permanently modified overall by bracing and frame stiffeners, so that a road test becomes necessary.
  • An object of the present invention is therefore to obviate the aforestated drawbacks of known lifting apparatus.
  • Another object of the invention is to provide a lifting apparatus of the said type which can satisfy the same lifting requirements in different sectors (such as workshops, private garages, boats and D.I.Y. or hobby applications).
  • the first stated object is attained by the lifting apparatus of the present invention, characterised by being composed of parts, each of weight not exceeding 25 kg, which can be assembled and disassembled by one person. Each part can be formed from several elements.
  • the lifting apparatus is formed from at least six parts, namely: A) a support and rotation device for the part B;
  • G support means for bracing the part A on the vehicle or for its resting on the ground.
  • a seventh part F is provided consisting of a relative operating device.
  • Two or more of the aforelisted parts can be previously fitted together to form a unit, but which must not weight more than 25 kg.
  • the various parts or units are then fitted together, when required, to form the lifting apparatus.
  • At least one of the component parts of the lifting apparatus of the present invention is formed as several interchangeable variants in order to cover different requirements, however no part must weight more than 25 kg.
  • Figure 1 is a side elevation of a lifting apparatus of the present invention
  • Figure 2 is a side elevation of three possible variants of the part A of Figure 1 ;
  • Figure 3 is a side elevation of two possible variants of the part B of Figure 1;
  • Figure 4 is a side elevation of four possible variants of the part C of Figure 1 ;
  • Figure 5 is a side elevation of four possible variants of the part D of Figure 1 ;
  • Figure 6 is a side elevation of two possible variants of the part E of Figure 1 ; and
  • Figure 7 is a side elevation of four possible variants of an accessory part not shown in Figure 1.
  • the lifting apparatus or small crane, represented therein, and designed to lift loads not exceeding 200 kg, comprises a part A forming the crane support and rotation device which besides carrying the part B (forming the so-called rotatable column or turret) enables this part to rotate in a horizontal plane.
  • the part B carries the parts D and C, being respectively the crane telescopic arm and the relative device for supporting and varying the inclination of this latter.
  • the control device, indicated by E, is used to wind or unwind the cable (not shown, but carried by the part D), on one end of which the load to be lifted is hung.
  • Figure 1 does not show two (F and G) of the aforesaid parts, namely the operating devices for the various crane functions and the support means for bracing the part A on the vehicle or for its resting on the ground.
  • the part F is however shown in Figure 7 in four possible variants, whereas the part G is not shown, being obvious to an expert of the art once it has been decided whether the crane is to be fixed to the floor of a truck or boat (for example by means of a backing flange or bracket), or is to be provided with its own specific structure for its resting on the ground (for example via a movable support trolley).
  • the part A (which, as stated, forms the device which besides acting as the support base, also enables the column B to rotate about its axis) can for example be constructed in three variants, indicated respectively by A1 (also shown in Figure 1), A2 and A3, of which A1 is a conventional manual push rotation device with a friction stop brake, A2 a conventional worm-type rotation device with handle operation, and A3 a conventional worm- type rotation device with hydraulic operation.
  • the device A presents conventionally an upperly open cylindrical cavity (not visible) into which the lower end of the column B is simply inserted.
  • the column B can be constructed for example in two variants, indicated by B1 and B2, which differ only by being of different height.
  • both the columns B1 and B2 present an upper horizontal through hole 10 and a vertical intermediate connector 12 fixed to the side of the relative column.
  • the outer edge of the connector 12 presents a series of notches the function of which is evident observing Figures 1, 4 and 5.
  • Figure 4 shows four possible variants of the support and raising device for the arm D (indicated by C in Figure 1), of which C1 (also shown in Figure 1) is a conventional adjustable support strut, C2 is a conventional hydraulic cylinder of closed circuit type with a locking valve, C3 is a conventional single-acting hydraulic cylinder, and C4 is a conventional double-acting hydraulic cylinder with a safety valve.
  • an eyelet (18, 20 respectively) is provided in each of the two ends to receive a relative peg or pin which enables (as will be apparent from Figure 1) one person to very easily and quickly fit the part C to the parts B (using one of the notches present in the connector 12) and D (using the through hole 16).
  • Figure 5 shows four possible variants of the part D, specifically a pack of telescopic box elements for manual extension by one withdrawal, indicated by D1 (this being also shown in Figure 1), a pack of telescopic box elements for manual extension by two withdrawals, indicated by D2, a pack of telescopic box elements for manual extension by a male-female thread system plus a manual mechanical extension, indicated by D3, and a pack of telescopic box elements for hydraulic extension plus a manual mechanical extension, indicated by D4.
  • two through holes, 14 and 16 respectively are present to receive relative pegs or pins, which enable (as will be apparent from Figure 1) one person to very easily and quickly fit the part D to the parts B and C.
  • the part E can also be constructed in two variants, of which one, indicated in Figure 6 by E1 (also represented in Figure 1) consists of a common handle-operated mechanical winch, whereas that indicated by E2 is formed of a conventional electric winch with safety brake.
  • the part F is not shown in Figure 1, meaning that it either need not be provided or can have various locations. In this respect, it can be applied to the part A or, if appropriate, to the floor of a truck or boat, or to the crane support trolley if provided.
  • the control device F is constructed in four variants, of which that indicated by F1 is a conventional hand pump with operating handle, that indicated by F2 is a conventional electro-hydraulic mini- control unit with a rise/descent pushbutton pad, that indicated by F3 is a conventional electro-hydraulic mini-control unit with a three-function command distributor, and that indicated by F4 is a conventional electro-hydraulic mini-control unit with a three- function remote control pushbutton pad.
  • the parts A3, C4 and D4 can be used for the crane. If instead the variants F1 or F2 are used, only the part C3 can be used. It should be noted that if the support and raising device is the variant C1 , the part F is not necessary.
  • the lifting apparatus of the present invention can cover the most varied requirements in lifting loads not exceeding 200 kg, by simply combining the aforedescribed variants of its component parts.
  • the illustrated and described variants of the various crane parts 58 different versions thereof can be obtained, for use on small capacity vehicles, vans, boats, fixed sites or mechanical workshops, and also for domestic or D.I.Y. use.
  • the crane does not require testing by the LHA or by the Ministry of Transport, in that because of the ease with which it can be removed and broken down it can be considered to be equipment which does not permanently modify the axle loading of the vehicle to which it is applied.
  • the crane can be easily and quickly broken down into parts, which must however not exceed 25 kg in weight. If appropriate, two or more parts can be preassembled to form a unit, provided the weight of this unit does not exceed 25 kg. In this manner the user has fewer parts to assemble in position.
  • the parts C and D in particular can be preassembled.
  • the lifting apparatus of the invention can be assembled and disassembled very easily means that it can be sold as an assembly box with the option of numerous additional kits, so that even a private individual can purchase it directly in a shop or supermarket in the most suitable version and assemble it alone at home.
  • a single lifting apparatus of the invention can serve two or more different locations by simply providing just the base supports in the various locations and then mounting the lifting apparatus on the base of that location where it is required.
  • the lifting apparatus of the present invention is composed of parts which have been known for a considerable time, the inventivity of the invention consisting in particular of having solved a problem involving a long felt but unsatisfied market requirement.
