All Crosby 320 Eye Hoist Hooks incorporate the following features:
♣ Designed with a 5:1 Design Factor.
♣ Chemical analysis and tensile tests performed on each PIC to verify chemistry and mechanical properties.
♣ The most complete line of Eye hoist hooks.
♣ Proper design, careful forging and precision controlled quenched and tempering give maximum strength without excessive weight and bulk.
♣ Every Eye Hook has a pre-drilled cam which can be equipped with a latch.
Even years after purchase of the original hook, latch assemblies can be added.
♣ Eye hooks are load rated.
♣ Available in carbon steel and alloy steel.
♣ Hoist hooks incorporate two types of strategically placed markings forged into the product which address two (2) QUIC-CHECK?features:
♣ Deformation Indicators and Angle Indicators (see following page for detailed definition).
The following additional features have been incorporated in the new Crosby S-320N Eye Hoist Hooks. (Sizes 3/4 ton Carbon through 22 ton Alloy.)
♣ Fatigue rated at 1-1/2 times the Working Load Limit at 20,000 cycles.
♣ Can be proof tested to 2-1/2 times the working Load Limit.
♣ Can be Metric Rated at 5:1 Design Factor.
♣ Low profile hook tip.
♣ New integrated latch (S-4320) meets the World class standard for lifting.
♣ Heavy duty stamped latch interlocks with the hook tip.
♣ High cycle, long life spring.
♣ When secured with proper cotter pin through the hole in the tip of hook,
meets the intent of OSHA Rule 1926.550(g) for personnel hoisting.
♣ 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. 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.
