Definitions

  • the invention relates to a mobile working platform with a flexible working position.
  • the well-known mobile working platforms work on the one hand on the principle of the scissor lift and on the other hand on the principle of the rotating car crane. All known mobile working platforms have the disadvantage that they only rotate around one point. This means that when the work platform is swung out, only the front sides of the stage are available as the working width for side work (cf. DEPS 39 13 645 C 1, DE OS 24 18 158).
  • the object of the invention is to design a work platform in its entirety with two pivot points. This makes it possible to use pivot point 1 via the basic principle of the mobile crane. A ball swivel connection between the load arm construction and the platform allows the platform to be rotated when the load arm is pivoted out. This means that the entire stage area can be used in every working position. Both the lifting and the pivoting process of the pivot point 1 and the pivoting process of the pivot point 2 are operated by using the on-board hydraulics. The work processes are controlled by solenoid valves and can be carried out in any working position from the work platform or carried out by the ground staff in an emergency.
  • the preferred area of application of the invention is assembly, disassembly and revision work on overhead lines for electrically powered locomotives.
  • the invention is characterized in that the rotatable neck support and the swivel ball connection between the support structure and the work platform as two pivot points in the overall system allow the flexibility of the work platform. Due to the flexible working position, it is possible to choose the stage working position in such a way that the optimal working surface is always used at the installation site.
