Definitions

  • the present invention relates to a crane and a method of assembling it; such crane is of the type that is used for moving goods from a means of transport to a fixed installation, particularly at construction sites, to build and/or repair houses.
  • the tower is erected by having it supported by an assist truck-mounted crane which supports the upper section, while operators mount the lower portions.
  • the object of this invention is to provide a crane that could obviate the above drawbacks, as defined in the annexed claims.
  • numeral 50 generally designates a crane of the type that comprises a tower T, at whose top a slewing member supports a counter-jib CF and a jib F for lifting and handling loads.
  • Such crane 50 has a hoist means 58 on the counter-jib part, in this example an auxiliary cantilevered hoist, which loads and positions the different elements E0, ... E14 of the jib F on corresponding sliding means, for successive assembly of the jib F.
  • the counterjib CF is comprised of a slewing member 55, a central element 56 and a winch and counterweight-holding end element.
  • the central element 56 and the slewing member 55 are adapted to hold, i.e. contain, an element E0, ... E14 of the jib F, and have the above mentioned sliding means.
  • the hoist means 58 is preferably attached to the element 56 so that the expected jib element may be attached thereto by means of a rope 58a.
  • a block pushing fork is contained in the counterjib CF and slides the element loaded by the hoist means 58 and held in the element 56 or in the central member 55.
  • the thrust action is conveniently provided by a hydraulic or pneumatic cylinder C1.
  • the elements E1, ... E14 of the jib F are successively loaded, one at a time, starting from the outermost lightest element.
  • the element loaded by the hoist means 58 is attached to the block pushing fork.
  • the crane 50 namely the tower T, has a climbing frame 54 for raising the counterjib CF /slewing member 55 unit to allow introduction of further successive tower elements 52 and increasing the height of the crane 50.
  • such climbing frame 54 comprises a hoist unit 10 which pushes the lower tower element 52 thereby lifting the upper element, its thrust action being given by a hydraulic cylinder 11.
  • the climbing frame 54 operates on and is fixed to a pushing member 53 located under the slewing member 55 and has an opening through which the tower element 52 to be added is introduced.
  • Such additional tower element 52 is lifted by the hoisting tackle 66 of the crane 50.
  • the elements E0, ... E14 of the jib are fastened together by pins and bolts.
  • Such cylinder C2 is attached to a beam 72 and its stem is attached to another beam 71, the former on the slewing member 55, the latter on the central element 56, so that, by operating the cylinder C2, the counter-jib CF rotates, due to its being pivotally mounted to the slewing member 55, and rises.
  • This arrangement is advantageous when the crane has to be rotated and an obstacle prevents rotation thereof.
  • the action of the hoist means 58 is also conveniently used for laying each jib element back on the ground once operation of the crane 50 is terminated.
  • the method of assembling the crane 50 includes a step of on-ground pre-assembling a tower section and counter-jib elements, such as a winch and counterweight-holding end element, a central element for loading the jib elements, including the slewing member and a pushing element; a step of assembling the jib, by loading and successively sliding the various jib elements that are loaded into the counter-jib CF by an auxiliary cantilevered host 58 located on the central element of the counter-jib CF; a step of fully assembling the tower by raising the counter-jib and/or the jib by means of a climbing frame; it being understood that the tower assembly step may precede the jib assembly step.
  • counter-jib elements such as a winch and counterweight-holding end element, a central element for loading the jib elements, including the slewing member and a pushing element
  • a step of assembling the jib by loading and successively sliding the various
  • the jib elements are loaded and attached from the lightest to the heaviest, i.e. from the outermost element, in this case the element E14 (tip element) to the centermost element, in this case the element E0.
  • each jib element is loaded and laid on corresponding sliding rollers and attached to a block pushing fork, which is driven by a hydraulic or pneumatic piston.
  • At least two elements 52 of the tower T are fastened together during on-ground pre-assembly.
  • the on-ground pre-assembly step starts with installation of the base 51 and relevant ballast.
  • the next steps are installation of a jib trolley limit stop with its support and power cord, application of trolley pulling ropes, and application of capacity signs and the safety rope.
  • the frame 54 has to be hung by the pawls 12 and the unit 10 on the corresponding tower element 52.
  • Such frame 54 also has upper 54b and lower platforms 54a.
  • hoist means 58 such as an auxiliary cantilevered hoist
  • hoist means 58 such as an auxiliary cantilevered hoist
  • such specification can also be extended to equivalent hoist means.
  • the hoist means 58 is located on a counter-jib CF element 56 or on the slewing member 55 in a cantilever relationship.
  • the on-ground pre-assembly step can be also carried out on vehicles.
