Definitions

  • the invention has for its object to provide a crane adapted to be used as a hoisting apparatus when erecting a building and to travel on a track supported at the building.
  • the legs of the platform which each are provided with one or more travelling wheels are mounted for vertical adjustment at the corners of the platform carrying the circular track for the jib, said 4 legs being adapted to be locked in their adjusted position and at least two supporting rollers being mounted at the under side of the platform at each corner thereof on opposite sides of the leg.
  • the platform carrying the circular track for the crane jib may be lowered in accordance with the height to which the load is to be elevated, so that the active length of the legs and their buckling length is reduced.
  • the supporting rollers at the under side of the platform may take over the load on the respective corner of the platform by moving the platform with said rollers onto the track of a higher storey of the building and thereafter the legs belonging to said supporting rollers may be raised.
  • the same operation may be repeated for the corners at the opposite side of the platform, so that the crane reaches a higher storey.
  • FIG. 1 is an elevation and FIG. 2 is a plan view of the crane travelling on tracks supported on transverse walls of a building in the state of erection.
  • FIG. 3 is an elevation of the crane as viewed in a direction at right angles to the elevation shown in FIG. 1 and the legs at one side of the platform being raised to the track of a higher storey.
  • FIG. 4 is a sectional elevation on a large scale of a rectangular casing for interconnecting the crossing beams in a corner of the platform.
  • FIG. 5 is a horizontal section of the casing taken on line V-V of FIG. 4.
  • FIG. 6 is a sectional elevation on enlarged scale of the lower end of one of the legs of the platform.
  • the crane by means of legs is supported on tracks 4 of I-shaped section, said tracks being supported on transverse walls 1 of a building having longitudinal beams 2.
  • the legs 3 carry a platform consisting of pairs of beams 5, 6 of I-shaped section.
  • On the platform 5, 6 a circular track 8 is mounted on which the horizontal jib 7 of the crane is supported for swinging movement by means of rollers 9 mounted at curved feet 10.
  • a winch 11 is mounted and is provided with e.g. two drums 12, 13 for hoisting a load and for moving a crab 43 on the jib.
  • the crossing beams 5, 6 at each corner of the platform are interconnected by a casing 14, in which the leg 3 is guided at the upper wall at 15 and at the lower wall at 16.
  • Each beam 5 and 6 completely extends through the casing 14 and the beams are supported and secured at the vertical walls of the casing by means of bolts 19, 20 in a frame 17 and 18 respectively provided at the walls of the casing.
  • a toothed rack 21 is provided at each leg, said rack meshing with a worm 22 journalled with its shaft 24 in a gear box 23 secured to the sides of the casing 14 by means of cheeks 25.
  • the gear box 23 also contains an electromotor 39 adapted to drive the wormshaft 24 through the intermediary of a pair of toothed wheels 26, 27 and a pair of bevel gear wheels 28, 29.
  • the leg 3 is locked in its position to the casing 14 by two locking bolts 30 acting in two perpendicular directions and which may be constituted by screw bolts screwed in a sleeve.
  • a rotatable sleeve 32 extends into the lower end of each leg 3 and an axle 34 carrying two travelling wheels is rotatably supported in said sleeve, one of said wheels having a toothing meshing with a bevel pinion 37 secured on a shaft 36.
  • the shaft 36 extends upwards through the leg 3 and at its end projecting out of the leg is coupled to an electromotor 38 by a toothed gearing 42.
  • the track 4 is provided with rails 40 on which the wheels 33 run, so that the crane will travel when the motor 38 operates.
  • a climbing construction crane comprising a substantially rectangular platform for support of a hoist mechanism and rotating jib, legs at the comers of said platform each provided at the bottom with at least one travellingwheel, means mounting said legs for independent vertical adjustment, and at least two supporting rollers mounted at the under side of the platform at each corner on opt posite sides of the corresponding leg.
