Description

  • These blocks are built to carry the increased loads of synthetic fiber ropes.
  • All hooks are heat-treated alloy steel.
  • You can now use a smaller size rope, and in turn, a smaller block, providing capacities which were previously not possible.
  • Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements.  Importantly, these blocks meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
