2-arm universal puller with sliding, always parallel Pulling hooks

Description

The 2-arm universal puller with adjustable pulling hooks and grease-hydraulic spindle is used for the particularly safe removal of extremely tight bearings, gears and discs in all common sizes for trades, workshops and industry. The grease-hydraulic spindle achieves an average pulling force of 20 tonnes. It can be used to loosen any component that sits on a shaft and is freely accessible from the outside. The mechanical spindle can be used for pulling operations with a tensile force of up to 10 tonnes and/or where space is limited.

Area of application

  • For the particularly safe removal of extremely tight bearings, gears and discs in all standard sizes for trade, workshop and industry.

Benefits Operation

  • Screw connection enables easy loosening and particularly tight fastening of the pulling hooks with a hexagon wrench

  • Grease-hydraulic spindle guarantees easy and controlled removal of particularly tight parts with little effort

  • The mechanical spindle can be used where space is limited and direct access to the component is required

  • Mechanical spindle has a rotating spindle tip for secure positioning on smooth surfaces and for centring

  • 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

  • Variable adjustment to any span between xx - xxx mm

  • Shear-resistant suspension of the claw in the slide piece (Armlock 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 a spanner to fasten the hooks
  • Operate the hexagon on the spindle head with a ratchet or combination spanner
  • Adjust the hydraulic spindle until the component is released
