QUIC-CHECKâ
is a patented concept developed
by Crosby's Research and Development Department which represents Crosby's
ongoing commitment to Quality. QUIC-CHECKâ
incorporates the strategic placement of marking indicators on traditional
rigging products to indicate reference points designed to enhance the
safe and proper use of Crosby products.
U.S. Patents 5,193,480 & 5,103,755 and foreign equivalents.

SHACKLES
G-2130 |
All Crosby
Shackles, except for G-2160’s incorporate markings forged into
the product which address an easy QUIC-CHECKâ
feature. Angle indicators are forged into the shackle bow
at 45° angles from vertical. These are utilized to quickly
check the approximate angle of a two-legged hitch or quickly check
the angle of a single leg hitch when the shackle pin is secured
and the pull of the load is off vertical or side loaded, thus requiring
a reduction in the working load limit of the shackle. |

HOOKS
Hoist hooks incorporate markings
forged into the product which address two (2) QUIC-CHECKâ
features:
|
 |
Deformation Indicators — Two strategically placed marks, one
just below the shank or eye and the other on the hook tip, which
allows for a QUIC-CHECKâ
measurement to determine if the throat opening has changed, thus
indicating abuse or overload.
To check, use a measuring device (i.e. tape measure) to measure
the distance between the marks. The marks should align to either
an inch or half-inch increment on the measuring device. If the measurement
does not meet this criteria, the hook should be inspected further
for possible damage. |
 |
Angle Indicators
— Indicates the maximum included angle which is allowed between
two (2) sling legs in the hook. These indicators also provide the
opportunity to approximate other included angles betweem two sling
legs. |

TERMINATOR™
WEDGE AND SOCKETS
|
|
Wedges for Wedge sockets incorporate a two hole Go/No-Go guaging system
which allows for a QUIC-CHECKâ
inspection, ensuring that the proper size wire rope is being used.
The proper size rope is determined when the following criteria are met:
|
| 1. The wire rope should pass through
the "Go" hole in the wedge.
2 The wire rope should NOT pass through the "No-Go"
hole in the wedge. |

MASTER LINKS
|
A-342 and A-345 Master Links
incorporate markings forged into the product which address two (2)
QUIC-CHECKâ
features:
Angle
Indicators — Forged at 45° angles at each end of the link,
they are utilized to quickly check the approximate included angles
between two sling legs. |
| Deformation
Indicators — Two strategically placed marks one on each
side of the link, which allows for a QUIC-CHECKâ
measurement to determine if the link dimensions have
changed, thus indicating abuse or overload. |
| To check, use
a measuring device (i.e., tape measure) to measure the distance
between the marks. The marks should align to either an inch
or half-inch increment on the measuring device. If the measurement
does not meet this criteria, the Master Link should be inspected
further for possible damage. |

LINKS AND
RINGS
|
| Crosby 341 Pear Shaped Links
and S-643 weldless rings incorporate the QUIC-CHECKâ
angle indicators forged into the product. |
S-643 |
Angle Indicators — Forged at 45° angles at each
end of the link, they are utilized to quickly check the approximate
included angles between two sling legs. |
