Safety Information - Read and Follow
|
| 1.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.
|
| 2.For
hooks used in frequent load cycles or
pulsating loads, the hook and threads
should be periodically inspected by
Magnetic Particle or Dye Penetrant.
(Note: Some disassembly may be required.)
|
| 3.Never
use a hook whose throat opening has
been increased, or whose tip has been
bent more than 10 degrees out of plane
from the hook body, 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.
|
| 4.Never
use a hook that is worn beyond the limits
shown in Figure 1.
|
| 5.Remove
from service any hook with a crack,
nick, or gouge. Hooks with a crack,
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.
|
| 6.Never
repair, alter, rework, or reshape a
hook by welding, heating, burning, or
bending.
|
| 7.Never
side load, back load, or tip load a
hook. (See Figure 2.)
|
| 8.Eye
hooks, shank hooks and swivel hooks
are designed to be used with wire rope
or chain. Efficiency of assembly may
be reduced when used with synthetic
material.
|
| 9.Do
not swivel the S-322 swivel hook while
it is supporting a load.
|
| 10.The
use of a latch may be mandatory by regulations
or safety codes; e.g., OSHA, MSHA, ANSI/ASME
B30, Insurance, etc.. (Note: When using
latches, see instructions in ñUnderstanding:
The Crosby Group Warningsî for further
information.)
|
| 11.Always
make sure the hook supports the load.
(See Figure 3). The latch must never
support the load (See Figure 4).
|
| 12.When
placing two (2) sling legs in hook,
make sure the angle from the vertical
to the outermost leg is not greater
than 45 degrees, and the included angle
between the legs does not exceed 90
degrees* (See Figure 5).
|
| 13.See
ANSI/ASME B30.10 ñHooksî for additional
information. |
*
For angles greater than 90 degrees, or more
than two (2) legs, a master link or bolt
type anchor shackle should be used to attach
the legs of the sling to the hook.

|
WARNING |
|
•Loads
may disengage from hook if
proper procedures are not

personnel hoisting by cranes
or derricks. A Crosby
319, 320, or 322 hook with
a PL Latch attached (when
secured with bolt, nut and
pin) may be used for lifting
personnel. A Crosby
S-320N Hook with a S-4320
Latch attached (when secured
with cotter pin or bolt, nut
and pin) may be used for lifting
personnel.
|
|
•Threads
may corrode and/or strip and
drop the load.
|
|
•Hook
must always support the load.
The load must never be supported
by the latch.
|

•Never
apply more force than the
hookÍs assigned Working Load
Limit (WLL) rating.
|
|
•Read
and understand these instructions
before using hook.
