  • the work platform also has a mobile boom that can be rotated about a vertical axis and at the end of which the pivot bearing is attached.
  • the mobile jib is a pneumatic crane.
  • a fastening point for the end of the crane rope is provided on the column in order to raise and lower the column with the crane rope.
  • the swivel bearing is connected to the boom by detachable coupling elements.
  • the coupling organs have both on the swivel bearing and on the boom, corresponding connecting parts that can be connected to each other by plug pins.
  • the catwalk is attached to both the upper and lower pillar ends.
  • a drive is also provided in order to pivot the sliding bearing.
  • DE-OS 30 11 945 describes an attachment device for a mobile crane with a length-adjustable boom that can be pivoted in the vertical direction and rotatable about a vertical axis.
  • This attachment is characterized by an L-shaped carrier, which has a fastening device for fastening to the boom end and a horizontal pivot axis at one leg to the free end of the other leg.
  • a support arm pivotally mounted on the pivot axis is provided, which can be pivoted by a hydraulic motor.
  • the support arm is connected to a work platform.
  • the support arm can be pivoted between two end positions, being oriented approximately parallel to the free leg in one end position and at right angles to it in the other end position.
  • DE-OS 39 11 677 discloses a working and manipulating device with a working mast composed of a plurality of arms which can be pivoted at their ends and which can be folded and unfolded, the basic arm of which is mounted on a swivel bracket which is expediently arranged on a chassis.
  • the end boom of the latter can be equipped at its front end with a tool which can be pivoted about an axis perpendicular to its longitudinal extent.
  • the implement can also be rotated about an axis parallel to the longitudinal extension of the end boom by at least 190 ° with respect to the end boom.
  • DE-OS 29 35 944 is a telescopic boom mounted on a trestle and pivotably arranged relative to the trestle provided, at the free end of a work platform is arranged so that the work platform is always aligned horizontally regardless of the inclined position of the telescopic arm.
  • the invention has for its object to provide an add-on crane that is independent of external energy supply, thus energetically self-sufficient, and with which it is also possible to lift components in the form of bulky plates and long beams or frames and / or a work platform and to position exactly, without it being necessary that this exact positioning is to be carried out with the construction or mobile crane and the like. Rather, it is sufficient to place the components and / or the working platform by means of the construction or mobile crane only in the vicinity of the assembly site bring to.
  • an automatically vertically aligning leveling module is arranged at the free end of the crane boom, that a vehicle-side rotating module is provided behind the leveling module, with which to rotate the components connected to the rotating module about an axis that is always vertically oriented by the leveling module are that a linear module is provided behind the rotary module and that a work platform or a working device is arranged on the linear module.
  • an energy module for example a hydraulic and / or electrical and / or pneumatic energy source driven by an internal combustion engine, can be provided for driving the attachment crane on the working platform or another component of the attachment crane.
  • the add-on crane is independent of the supply of external energy, for example via an electrical cable, so that it can also be used at locations or construction sites which are not connected to an electrical supply network, for example.
  • the energy module can expediently have additional connections for supplying energy to the connectable positioning device and the tools of the fitters. - This means that the positioning device and the tools of the fitters are independent of the supply of energy from outside.
  • the horizontally and / or vertically operating linear module is advantageously oriented in the vertical direction and is height-adjustable in relation to the rotary module.
  • a telescopic linear module is expediently mounted so that it can pivot about two parallel horizontal axes behind the vertical rotary module on the vehicle and is designed as a telescopic mast.
  • the telescopic linear module can have one at both ends at right angles to the longitudinal axis of the telescopic linear module have horizontal horizontal axis of rotation, which transmits the vertical alignment of the leveling module to the modules or positioning device or work platform connected on the assembly side via an arrangement for positive synchronism.
  • the add-on crane is expediently designed in such a way that a working platform is arranged on the linear module and is height-adjustable, horizontally adjustable and rotatable relative to the leveling module. - This enables all movements required in practice.
  • a vertically aligned rotating module can be provided between the rotating module and the working platform or the positioning device.
  • a working platform is expediently provided at the free end of the linear module.
  • a lifting module is arranged at the vehicle-side end of the positioning device, which is to be connected to the add-on crane or the work platform and, in relation to this or this, is adjustable in height by means of a lifting drive and can be fixed at the desired height, that at the front the lifting module a sliding module is slidably mounted on both sides and can be moved by means of a sliding drive and can be locked in a desired side position that a spacing module is provided on the front of the sliding module and can be lengthened or shortened in the longitudinal direction by means of a spacing drive and kept in the desired position and that a swivel module is movably mounted on the front of the spacing module and can be swiveled by means of a swivel drive and locked in the desired swivel position.
  • An inclination module can be provided between the sliding module and the spacing module, which is inclined by means of an inclination drive in both inclination directions about an inclination axis oriented in a plane parallel to the corridor plane at right angles to the longitudinal direction of the front attachment.
  • a rotary module can also be provided between the spacer module and the swivel module, which is to be rotated in both directions of rotation by means of a rotary drive about a vertical axis of rotation extending through the central longitudinal axis of the spacer module.
  • a frame which is firmly connected to the mobile working device and on the working side vertical rotary module a mounting-side frame is provided that both frames are pivotally connected to each other via a horizontal pivot axis and that the free end of the vehicle-side frame and the free end of the mounting-side frame are driven by means of a thrust piston transmission.
  • the required rotary movement can also be carried out via a rotary piston drive.
  • the modules can be swapped or omitted for simpler applications.
  • a vehicle-side frame 14 is provided at its free end 11 via connecting members 12, 13, which is pivotally connected to a mounting-side frame 16 via a swivel joint 15.
  • the cylinder 17 of a thrust piston gear 18 serving as level control is connected in a joint 19, while the piston rod 20 of the thrust piston gear 18 is connected in an articulation 21 of the mounting-side frame 16.
  • a rotary module 24 is provided on the assembly-side frame 16 by means of a coupling 22, 23 and is rotatable about the axis of rotation 25.
  • a vertical linear unit 28 is provided on a coupling 26, 27 of the rotary module 24 and can be moved up and down in the direction of the double arrow 30 by means of a motor 29.
  • a horizontal linear unit 31 is arranged on the vertical module 28 and can be moved forwards and backwards in the direction of the double arrow 33 by means of a motor 32.
