All qualified persons responsible for assembly, disassembly, operation, inspection, and maintenance shall read and understand all the contents of this manual to avoid serious injury, death, or property damage. Keep this manual.

​

Your new Model 34, Four Point Spreader Beam, is a load supporting lifting attachment, which only supports loads up to the maximum capacity when loaded correctly. The Model 34 is for specific tasks, withstanding forces based on the unit’s maximum capacity. The assembly, disassembly, operation, inspection, and maintenance instructions in this manual are typical of the Model 34. Use the following guidelines in this manual for your protection and for optimal operation of your equipment. The safety precautions listed in this manual are not all-inclusive. The owner or user is responsible for understanding and acting according industry standards and any other location, city, state, and federal regulations.


Also, your unit may look different than the pictorial images in this manual, however, the information: safety, operating, loading, and disassembling applies to your lifting unit.


Equally important, modifications to your lifting equipment without prior written approval from
The Caldwell Group voids your warranty. Refer to ASME B30.20, regarding liability of
repaired or modified lifters

  • An appointed person shall visually inspect the lifter on a daily
    or weekly schedule, depending on the severity of service.

  • Establish a regular inspection schedule:

Inspecting

SAFETY

Visual examination by the operator before and during each lift.

Visual examination by the operator or other designated persons - records not required.

Normal service…………………….. monthly
Heavy service……………………….weekly to monthly
Severe service……………………...daily to weekly
Special or infrequent service……...qualified person recommendation

Visual inspection by a qualified person,keeping records for continuing evaluations.

Normal service…………………….. monthly
Heavy service……………………….weekly to monthly
Severe service……………………...daily to weekly
Special or infrequent service……...qualified person recommendation

Inspect the Model 34 for any visible damage:

​

—cracks, excessive wear, deformation, any damage:

 

  • end pipes

  • hook attachment points

  • fasteners

  • slings

  • hoist ring

  • shackle

  • end fitting

—loose, damaged, or missing:

 

  • fasteners

  • slings

  • hoist ring

  • end fitting

  • product safety labels

BEFORE attaching the load, verify the following:

 

  • The top rigging is securely attached to all four end fittings.

  • The four end pipes are securely fastened into all four end fittings.

  • The bottom rigging is securely attacked to all four shackles.

 

1. Know the:

  • weight of the designated load.

  • size of the designated load.

  • location of the load’s center of gravity.

  • Model 34’s rated capacity.

​

2. Confirm the weight of the load is equal to or less than the Model 34’s rated capacity.
 

3. Confirm the Hoist’s rated capacity is equal to or greater than the combined weight of the load and the Model 34.
 

4. Confirm the bottom rigging’s rated capacity is equal to or greater than the Model 34’s rated capacity.
 

5. Slowly position the Model 34 above the load.

​

6. Confirm the center of both the hoist and the Model 34 top rigging is in-line with the load’s center of gravity.

​

7. Attach the bottom rigging slings to the load.

​

8. Again, verify the center of the hoist is in-line with the load’s center of gravity, front view and side view.
 

9. Verify the load’s center of gravity is symmetrically located between the bottom rigging hooks, front view and side view.
 

10. Perform a test lift of several inches, verifying:

 

  • the load is secure and properly balanced.

  • the load is level and horizontal.
     

11. Do NOT suddenly accelerate or decelerate a loaded or unloaded Model 34 , while lifting or transporting.

4. After removing the end pipes, the top rigging remains connected to all four end fittings.

Page 10
_34_FSB__4ptSpreadBeam___REV_00-11 copy.jpg

Top rigging must be at a 45 degree angle, as shown below.
Hoist ring socket head cap screw must meet manufacturer’s torque specs.
For manufacturer's specs, see http://www.thecrosbygroup.com/html/en-US/pdf/pgs/182_184.pdf

Disassembling

DISASSEMBLING

1. To remove the top rigging from the Model 34, loosen the hoist ring socket head cap screw.

When re-assembling the top rigging, confirm the rigging angle is 45 degrees from the inside of all four end fittings and chain legs; and confirm the hoist ring manufacturer’s specs have been met.
