Definitions

  • the invention relates to a telescopic tower car working platform.
  • the known tower car working platforms of this type have the disadvantage that the constructional design of the lifting, swiveling and rotating platform means that there is a limited range of action which cannot comprehensively detect all the components belonging to the overhead contact line system.
  • the invention has for its object that an extension of the support arm is achieved by a hydraulic telescopic device, thereby enlarging the working area so that the use of another tool is unnecessary.
  • the enlargement of the working area of the assembly platform is achieved in that the support arm, which consists of two nested components, is designed to be variable in length via a double-acting hydraulic cylinder.
  • the preferred area of application of the invention is assembly, disassembly and revision work on overhead lines of the electrically operated traction vehicles and signaling devices.
  • Figure 1 General view of the telescopic tower truck working platform position 1 retracted condition Position 2 extended condition
  • the invention is characterized in that the support arm between the rotatable neck support and the support structure of the work platform is designed to vary in length.
  • the support arm which has a double design, can be modified by changing the length of the double-acting working cylinder.
  • the effective range of the work platform changes due to the double construction of the support arm.
