Play detector hydraulic for working pit until 20 t axle load

Information request

  AST-Pit delivery scope:
• Two floor assemblies with hydraulic cylinder for lateral and lengthwise movement
• Hot-dip galvanised test plates
• A high-performance hydraulic unit with control box, main switch, switching and controller elements
• Operating unit with rocker switch and 12m cable 

• The powerful, hydraulically activated test plates move against each other laterally and lengthwise
• The specific movement process of the test plates makes the disengaged or loose axle and steering parts immediately visible
• Both designs use hot-dip galvanised test plates with a width of 900 mm and a length 700 mm offer sufficient set-up area for both twinned wheels and also hold up against bending thanks to their 12 mm thickness.
• The compact control box, including main switch, is mounted directly on the hydraulic unit

All SHERPA play detectors of the type series AST-Pit comply, together with the respective options, with the current EU Directive 2014/45/EU.
