Benefits Operation

  • Narrow pulling hooks grip optimally in narrow and poorly accessible spaces

  • Easy, manual release of the pulling hooks by means of turning the manually adjustable wheel (Quick Adjust Technology)

  • Easy application also with eccentric components due to free-moving pulling hooks sliding off the crossbar

  • Hexagon drive on the crossbeam, for safe counter holding

  • Quick-adjustable Pulling hooks guarantee immediate adjustment to any span between 4 mm - 350 mm

  • Shear-resistant suspension of the claw in the slide piece (Armlock Technology)

  • Secure positioning of the spindle thanks to the rotatable spindle tip, both on smooth surfaces and when centring (Switch Technology)

  • Optionally convertible from an external extractor to an internal extractor by reversing the pulling hooks

  • Anti-slip guard on the spindle head for safe working with wrench

  • Spindle riser protects the threading

  • Attach the Pulling hook to the part to be extracted from the outside
  • Slide the claws under the component
  • Use the hand knurl to manually fasten the hooks
  • Pull the spindle manually under pressure to fix it
  • Use a ratchet or combination spanner to move the hexagon on the spindle head until the component is released
