Crosby 'S319' Shank Hooks with Optional Safety Latch, WLL Range from 500kg to 30,000kg

S-319 Shank Hook With Latch S-319 Shank Hook No Latch Crosby 319 Shank Hooks

The Crosby S319 Hoist Shank Hooks from 500kg to 75 tonnes incorporate markings forges into the product which address two (2) QUIC-CHECK features. They are supplied designed with 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 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 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.
  • Patented trademark indicates QUIC-CHECK product.

Description

+

The Crosby S319 Hoist Shank Hooks from 500kg to 75 tonnes incorporate markings forges into the product which address two (2) QUIC-CHECK features. They are supplied designed with 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 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 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.
  • Patented trademark indicates QUIC-CHECK product.

Hook I.D. Codes

  • A - Alloy Steel
  • B - Bronze High Strength
