WARNINGS AND APPLICATION
INSTRUCTIONS

Important Safety Information -
Read and Follow

  • A visual periodic inspection for cracks, nicks, wear, gouges and deformation as part of a comprehensive documented inspection program, should be conducted by trained personnel in compliance with the schedule in ANSI B30.10.
  • For hooks used in frequent load cycles, pulsating loads or severe duty as defined by ASME B3010, the hook and threads should be periodically inspected by Magnetic Particle or Dye Penetrant. (Note: Some disassembly may be required.)
  • Never use a hook whose throat opening has been increased 5%,not to exceed 1/4", or shows any visibile apparent bend or twist from the plane of the unbent hook, or is in any other way distorted or bent.  NOTE:  A latch will not work properly on a hook with a bent or worn tip.
  • Never use a hook that is worn beyond the limits shown in Figure 1.
  • Remove from service any hook with a crack, nick, or gouge. Hooks with a nick or gouge shall be repaired by grinding lengthwise, following the contour of the hook, provided that the reduced dimension is within the limits shown in Figure 1. Contact Crosby Engineering to evaluate any crack.
  • Never repair, alter, rework, or reshape a hook by welding, heating, burning, or bending.
  • Never side load, back load or tip load a hook. Side loading, back loading and tip loading are conditions that damage and reduce the capacity of the hook. (See Figure 2).
  • S-326A can be used for limited rotation (infrequent, non-continuous).

    WARNING

  • Loads may disengage from hook if proper procedures are not followed.
  • A falling load may cause serious injury or death.
  • Positive locking latch will unlock when trigger is depressed. Never use hook unless hook and latch are fully closed and locked.
  • Keep body parts clear of pinch point between hook tip and hook latch when closing.
  • Keep hand(s) from between throat of hook and sling or other device.
  • Do not use hook tip for lifting.
  • Shank threads may corrode and/or strip and drop the load.
  • Remove securement nut to inspect threads for corrosion or to replace S-326A bearing washers (2) and or S-3326 thrust bearing.
  • Never apply more force than the hook’s assigned Working Load Limit (WLL) rating.
  • See OSHA Rule 1926.550 (g) for personnel hoisting by cranes or derricks.  A Crosby 316A, 317A, 318A, 326A, 3326, 1316A, or 1317A hook may be used for lifting personnel.
  • Use only genuine Crosby parts as replacements.
