Problem:

Poor quality and wear can cause the Thrower Arm to function poorly or break.

  •  Excess wear can impede the thrower arm from opening the coupler knuckle
  • Poor casting quality can create fit issues and prevent smooth operation of the coupler
  • Poor material quality can cause premature failure of the thrower arm

Solution:

Pennsy’s line of Thrower Arms

To ensure proper function and universal fit in interchange, Pennsy’s line of Thrower Arms were designed using 3-D scans of a multitude of Throwers and Coupler bodies.
Thrower Arm dimensions and material properties are routinely checked to verify product conformity.

Results:

  • Thanks to Pennsy’s database of scanned coupling components and quality control system, Pennsy avoids many of the fit issues found in the field
  • Pennsy’s strict material controls prevent premature failures in the Thrower Arm
  • All Pennsy products are clearly marked and identifiable
