Detection of the position and angle of a turntable ladder

In order to position a turntable ladder accurately and to be able to act immediately in an emergency, it is essential to accurately record the position of the turntable and the angle of the ladder in relation to the undercarriage. By using the WDGA 36J absolute encoder, it is possible to precisely repeat the motion sequences for positioning the aerial ladder. The robust and compact design of the WDGA 36J, which is available with various interfaces (for example CANopen), makes it an excellent sensor solution.

Important features:

  • EnDra®: Maintenance-free and environmentally friendly
  • CANopen, single- and multi-turn
  • Communication profile CiA 301
  • Device profile CiA 406
  • Single-/Multiturn (max. 16 bit / 43 bit)
  • Trend-setting technology with 32 bit processor
  • 2-colour LED as display of operating status and error message according to CiA 303-3
  • Protection class IP67 + IP69K (high pressure / steam jet cleaning)
  • High bearing loads: 300 N axial / radial

Precise extension of a turntable ladder with the assistance of a Draw-wire system

The SZG165 cable pull system is used to precisely control the extension of the aerial ladder. It allows the determination of the exact length of the extended ladder. Intelligent design and robust mechanics ensure high repeatability. The SZG draw-wire systems, which are available in various lengths, are therefore perfectly suited to this application.

Important features draw wire system SZG60:

  • Ball bearing mounted swivel
  • Stainless steel measuring cable
  • Plain bearing guide
  • Quick mounting option
  • High resolution
  • Incremental and absolute versions
  • High precision mechanics with high linearity
