  • Small to medium arc travel length is typical
  • Operator boom access is not needed

The Scarab Series

The Scarab Series could be right for you if:

  • You need to handle loads up to 3,000 lbs
  • You need 6–30 ft lift and reach range
  • Medium to long arc travel length is typical
  • You would benefit from operator boom access
