HR-1000 Swivel Hoist Ring
Instruction Manual

Hoist Ring Application Assembly Safety

• Use swivel hoist ring only with a ferrous metal (steel, iron) or soft met(i.e., aluminum) load (workpiece). Do not leave threaded end of hoistring in aluminum loads for long time periods due to corrosion.
• For subsea or marine environment applications, use the HR-1000CTseries Hoist Ring only.
• After determining the loads on each hoist ring, select the proper size hoist ring using the Working Load Limit ratings in Tables 1, 3, and 5 for UNC threads and Tables 2, 4 and 6 for Metric threads (on next page).
• Drill and tap the workpiece to the correct size to a minimum depth of one-half the threaded shank diameter plus the threaded shank length.See rated load limit and bolt  torque requirements imprinted on top of the swivel trunnion (See Table 1 through Table 6 on next page).
• When a hoist ring is used in a side load application, ensure equal loadingon the pins by aligning the bail as shown in (Fig. 3).
• Always be sure total hoist ring bushing mating surface is in contact with the (workpiece) surface. Drilled and tapped hole must be 90 degrees to load (workpiece) surface.
• Install hoist ring to recommended torque with a torque wrench makingsure the bushing flange meets the load (workpiece) surface.
• Never use spacers between bushing flange and mounting surface.
• Always select proper load rated lifting device for use with Swivel HoistRing.
• Attach lifting device ensuring free fit to hoist ring bail (lifting ring) (Fig. 1).
• Apply partial load and check proper rotation and alignment. There should be no interference between load (workpiece) and hoist ring bail (Fig. 2).
• Special Note: Recommended thru hole clearance is 1/32″ for bolts smaller than 1″ and 2/32″ for bolts 1″ and larger in diameter.

Hoist Ring Inspection/Maintenance

• Always inspect hoist ring before use.
• Regularly inspect hoist ring parts.
• Never use hoist ring that shows signs of corrosion, wear or damage.
• Never use hoist ring if bail is bent or elongated.
• Always be sure threads on shank and receiving hole are clean, not damaged, and fit properly.
• Always check with torque wrench before using an already installed hoist ring.
• Always make sure there are no spacers (washers) used between bushing flange and the mounting surface. Remove any spacers (washers) and retorque before use.
• Prior to loading always ensure free movement of bail. The bail should pivot 180 degrees and swivel 360 degrees.

WARNING

• Loads may slip or fall if proper Hoist Ring assembly and lifting procedures are not used.
• A falling load may cause serious injury or death.
• Install hoist ring bolt to torque requirements listed in tables 1, 2, 3, 4, 5, & 6 for the HR-125, HR-1000, HR1000CT, HR-125M, HR-1000M and SS-125.
• Read, understand and follow all instructions and chart information.
• Do not use with damaged slings, chain, or webbing. For inspection criteria see ASME B30.9.
• The tension of the sling must be calculated or measured and can not exceed the working load limit (WLL) of the load connection fitting.
• Use only genuine Crosby parts as replacements.

Operating Safety

• Never exceed the capacity of the swivel hoist ring, see Tables 1, 2 and 5 for UNC threads and Tables 3, 4 and 6 for Metric threads (See next page for tables.).
• When using lifting slings of two or more legs, make sure the forces in the legs are calculated using the angle from the horizontal sling angle to the leg and select the  proper size swivel hoist ring to allow for the angular forces.
