Crosby® Shank Hooks

The most complete line of shank hoist hooks. Available 3/4 to 300 metric tons
Hook Identification code forged into each hook
Available in carbon steel, alloy steel, and bronze
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 101 - 103. Even years after purchase of the original hook, latch assemblies can be added
Type Approval and certification in accordance with ABS 2006 Steel Vessel Rules 1-1-17.7, and ABS Guide for Certification of Cranes

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 tip, 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 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 between two sling legs
Chemical analysis and tensile tests performed on each PIC to verify chemistry and mechanical properties
