Adjustment of the container spreader to different container sizes

A spreader is essential for container handling in ports or inland terminals. Quick and reliable adjustment of the spreader to different container sizes is essential. Wrong adjustments can cause serious damage, for example by containers falling over. The encoder WDGA 58B is used for precise positioning of the holding device, determining the exact value and allowing the spreader to be adjusted accurately. Various interfaces are available for the absolute encoders.

Positioning of a crane boom

To extend a crane boom with positional accuracy, it is necessary to detect the angle of rotation and the position. With the encoder WDGA 58S, an accurate position can be detected and an angle can be precisely determined. Due to its robust and compact design, the encoder WDGA 58S with the CANopen interface is very well suited for this application.

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
  • Salt spray resistant according to DIN EN 60068-2-11
  • Protection class IP67 + IP69K (High pressure / steam jet cleaning)

Positioning of stabilisers and booms on mobile cranes

To ensure a mobile crane's stability, stabilisers need to be able to extend flexibly and adjust precisely. The high precision mechanics and reliable length measurement of the draw-wire system make it ideal for stabiliser positioning. They are available with measuring ranges up to 40 m and with absolute and incremental encoders. Specially designed for harsh environments, they are the ideal solution.

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
