RA110 Spreader Beam

RA110 Spreader Beam

The spreader beam is designed for lifting and transporting equipment and cargo weighing up to 110t. It is adjustable every 1ft within the range of L=6ft to L=46ft, as specified in the manual. The spreader beam is intended to work solely in conjunction with lifting units equipped with appropriate chain or line slings.

Specification

Spreader Beam RA110 WLLmax=110t, Lmax=46ft consists of:

  • 2 end units RAK: 3ft
  • Struts RA used to adjust the span: 1ft, 2ft, 3ft, 4ft, 6ft, 12ft
  • 2 shackles WLL=55t and 2 shackles WLL=85t
  • Maximum weight of the spreader beam, according to the recommended configuration, is 2216,8 lbs
  • Carrying capacity from 15t to 110t
  • The α angle between the beam and sling is 45° or more
  • Use a bolt set to tighten (bolt+washer+nut) class 8.8. as per EN ISO 4014
  • Bolt tightening torque 260 Pound-Foot. Spanner size required 36mm
  • Torque wrench and ring spanner are recommended as additional equipment

Notice

  • The guidelines outlined in ASME B30.20 – 2021 must be followed when using the A-LIFT equipment.
  • Never exceed the indicated WLL; adhere to the WLL values listed in Table 2 for the specific sling angle used.
  • To ensure the safe use of the spreader beam, the top sling length is essential – refer to Table 2.
  • Under no circumstances should a load be suspended from the tube or flanges, as the spreader is designed for axial
    compression and not intended for bending.
  • Shackles are not a part of the spreader beam. They are an additional option selected as per customer’s needs.

COMMON RIGGING MISTAKES

  1. Correct sling set up example.
  2. Incorrect. Upper slings are not attached to the end units.
  3. Incorrect. The second pair of slings below cannot be attached to the spreader beams.
  4. Incorrect. Sling angle α cannot be less than 45°

Assembly Method

  • Verify the size of each A-LIFT component by checking its tag ID to ensure the correct size is being used.
  • Arrange the beam elements on a flat surface according to Table 1 to prevent rolling.
  • Before connecting, make sure that all elements and fasteners are free of any debris.
  • Assemble the components using the provided bolts, nuts, and washers. Tighten bolts to the torque values specified.
  • To ensure the safe use of the spreader, especially for longer spans, the quantity and quality of bolts are crucial.
  • Put the jaw of the top shackle over the jaw of the end unit and attach a top sling to the top shackle’s body.
  • Repeat the process for the other end of the spreader beam after inserting the top shackle pin through the shackle
    and the end unit jaw.
  • Attach the crane hook to the free ends of the top slings.
  • Attach lower slings and shackles to the lower holes of the end caps, and then connect them to the load to be lifted.
  • Prior to lifting, a competent person must conduct a comprehensive inspection of the assembled spreader beam and lifting rig.

Attention!

  • Ensure that the beam is loaded exclusively through the RAK end units only.
  • Ensure the use of the correct top slings and avoid needless twisting of any slings.
  • Keep obstacles away from the loaded spreader, as any contact could result in beam failure.
  • Do not exceed the specified WLL for a particular span. Refer to Table 2.
  • Avoid hanging any loads from the spreader tube, flanges, or support stands.
  • Use tag lines to control movement when moving or positioning long elements or assemblies.
  • Individual components might be heavy; therefore, exercise utmost caution when manual handling is necessary.
