Forged - Quenched and Tempered.
Proper design, careful forging, and precision controlled quench and tempering gives maximum strength without excessive weight and bulk.
Every Crosby Swivel hoist hook has a pre-drilled cam which can be equipped with a latch. Simply purchase the latch assemblies listed and snown on pages 89-91. Even years after purchase of the original hook, latch assemblies can be added.
Load rating codes stamped on each hook. 322 Swivel Hooks use the same load rating code as 319 Shank Hooks, see page 84 for proper Hook Identification Codes.
Hoist hooks incorporate markings forged into the product which address two QUICK-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.
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.

Features
Bearings
The 4 1/2" Block is fitted with special bronze bush but can be fitted with taper roller bearings wIth special bronze bush if requested.
Capacity
The 4:1 capacity load given in the table are the maximum head fitting loads that should be applied to the Blocks.These capacity loads are based on a Fador of Safety of 4:1 and the Blocks are proof tested to twice this capacity load.The table also details a comparative capacity
load at Fador of Safety2:1 so that the users may compare the 'High Load' Blocks with alternative makes based on this Lower Safety Fador.
Double Sheave
Light champion snatch block as a double sheave block.
Drop forged swivel hook or swivel shackle.
Can be furnished with bronze bushing and roller bearings.
Opening features permits easy insertion of wire rope in both sheaveswith removal of one bolt.
Can be furnished with hook latch.
Pressurelube fittings.
Fatigue rated.
Proof Load Testing
After final heat treatment slings with accessories shall be tested as an assembly, multi- leg chain slings shall be tested in sections. Individual sections of the chain slings shall be subjected to 2.0 times the load to which the section will be subjected when the assembly is subjected to its working load limit in accordance with the plan.
Lifting capacity of sling / working load limit (MT)
Rating
Single Branch slings
Single branch slings shall have a working load limit equal to that of the Chain used in their construction
Multi Branch slings
Multi branch slings shall be rated at a uniform working load limit for an angle between branches of 90o-120o(45o- 60o to the vertical) or additionally a ta uniform working load limit for any angle between branches of 90o-120o(45o- 60o to the vertical ).
Uniform Load Method
Double branch slings
For all angles between branches from 0°- 90° (0°- 45° to the vertical)
WLL = 1.4 x WLL of a single branch made from similar chain. When additionally marked for angles between branches of 90°- 120° (45°- 60° to the vertical)
WLL = 1 x WLL of single branch made from similar chain.
Three and four branch slings
For all angles between branches from 0°- 90° (0°- 45° to the vertical)
WLL = 2.1 x WLL of a single branch made from similar chain. When additionally marked for angles between branches of 90°- 120° (45°- 60° to the vertical)
WLL = 1.5 x WLL of single branch made from similar chain.
