S-319 / S-319N Crosby® Shank Hooks

S-319 / S-319N

Hoist hooks incorporate markings forged into the product which address two (2) QUIC-CHECK® features.

• Deformation Indicators -- Two strategically placed marks, one just below the shank or eye and the other on the hook up, which allows for a QUIC-CHECK® 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 according to the dimensions in column "AA" on next page. 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 allow between two (2) sling legs in the hook. These indicators also provide the opportunity to approximate other included angles between two sling legs.

Chemical analysis and tensile tests performed on each PIC to verify chemistry and mechanical properties.

Patented trademark indicates QUIC-CHECK® product.

Hook ID Codes: A-Alloy Steel, B-Bronze High Strength, C-Carbon Steel.

* NOTE: Proof load is 2 times Working Load Limit. All carbon hooks - average straightening load (ultimate load) is 5 times Working Load Limit. Alloy shank hooks 1.25 ton through 300 ton - average straightening load (ultimate load) is 4 times Working Load Limit. All bronze hooks-average straightening load (ultimate load) is 4 times Working Load Limit.

+ New 319N style hook.

++ See column "Y" on following page for actual length.

The most complete line of shank hoist hooks. Available 3/4 to 300 tons.
Available in carbon steel, alloy steel, and bronze.
Quenched and Tempered.
Proper design, careful forging, and precision controlled quench and tempering give maximum strength without excessive weight and bulk.
Every Crosby Shank Hook has a pre-drilled cam which can be equipped with a latch. Simply purchase the latch assemblies listed and shown on pages 97-99. Even years after purchase of the original hook, latch assemblies can be added.
Hook Identification code stamped on each hook.
