LOAD RESTRAINT GUIDELINECHS Tubes - hexagonal bundles

1. This guideline applies to:

2. Equipment requirements

• Trailer headboard should be above the entire load*. Typical load height is 1500 mm up to a maximum of 1750 mm.

• Side pins – minimum of 2 pairs of 1500 mm high above the bed of the trailer covering each length of tube.

• Base layer of square section timber dunnage to be used between the trailer bed and the load.

• Packing timbers shall be a minimum size of 60 x 60 mm square cross-section.

• All restraints must be web lashings compliant with EN 12195-2:2001 with a minimum lashing capacity of 2000 daN. Note that over-the-top lashings can be applied either under or over sheeting.

• Circular hollow section tubes, bundled and banded into hexagonal packs.

• Surface conditions: self-coloured, Rust Veto anti-corrosion coated, galvanised, shotblasted and painted, epoxy coated, polyethylene coated.

• The lowest friction factor determined as per EN 12195-1:2010 Annex B.1.2 is m = 0.29. This figure is valid in dry conditions - the majority of loads will be sheeted or transported in covered trailers.

This Load Restraint Guideline is designed and tested to meet the forces for road and sea transport as stated in EN 12195-1:2010 and VDI 2700.

* The restraint system does not rely on the trailer headboard, it will work with the load either to, or away from, the headboard - see Section 6.

3. Overview of restraint system

• Pyramid load build with a maximum of 2 bundles on top row or see Section 5.

• Load to headboard when axle loads allow.

4. Load build

P Apply timber dunnage to ensure clamping throughout the load.

P Where there are uneven bundle heights across the load, short lengths of dunnage should be applied at approximately 45o to fill the gaps.

P Apply full-width timbers between rows of tube bundles and ensure they are level and cannot topple off any shorter timbers.

P Full-width timbers must be a minimum of 75 x 75 mm square cross-section.

P No unblocked vertical gaps in top row.

P Maximum overhang of longer tubes on shorter tubes is 1m.

• All bundles within the load must be adequately clamped down by the straps. This will be achieved if timber dunnage is applied carefully during the load build.

• Top row of tubes must only contain a maximum of 2 bundles unless belly-wrap lashing are applied - see Section 5.

Incorrect load build

O More than 2 bundles on top row - centre bundle is not clamped down by over-the-top web lashings - use Section 5 method.

O Full-width timber is not level - risk of bundles sliding off.

O Insufficient packing timbers - bundles not clamped down.

O Do not double stack timbers in line with each other - risk of toppling off - place at 45o.

Maximum overhang 1m

Note: A variety of sizes of shorter length packing timbers will be required to ensure adequate clamping throughout the load.

Full-width timbers between rows minimum size 75 x 75 mm

5. Top layer with more than 2 bundles

In order to apply a belly-wrap lashing to the top layer of tubes with a ratchet tensioner on each side:

1. Thread a web lashing nearly all the way through a ratchet tensioner - leaving approximately 500 mm of free strap between the strap hook and the ratchet.

2. Put one and a half turns on this ratchet to secure the strap in the ratchet.

3. Attach the ratchet hook to a lashing point on the trailer (leaving the strap hook loose).

4. Throw the free end of the attached strap over the load.

5. Pass the strap back under the top layer of tube bundles.

6. Throw the free end of the strap back over the load and attach it to a lashing point on the other side of the trailer with a second ratchet tensioner.

7. Tighten the second tensioner.

8. Re-tighten the first tensioner.

An alternative method of applying a belly-wrap lashing can be found in the Technical Information Sheet TIS-0001.

Cross-sectional view of belly-wrap restraint showing ratchet tensioners on both sides

• The top layer must be restrained with 4 belly-wrap lashings.

• Each belly-wrap lashing must have a ratchet tensioner on each side.

• Apply belly-wrap lashings before the over-the-top lashings.

Note: Belly-wrap lashings must be applied before sheeting the load.

6. Blocking to the trailer headboard

The restraint system has been designed and tested to be compliant with the forces in EN 12195 without the need for any blocking, but blocking can be added to meet local enforcement requirements when transiting countries that insist on it.

7. Severe winter weather advisory periods

Whenever a load is either placed directly against the trailer headboard, or blocked with timber frames, then the trailer headboard should be rated to EN 12642 Code XL or equivalent to avoid the risk of damage.

Gap filled e.g. with Euro pallets

During severe winter weather advisory periods when there is a chance of ice forming on timbers, anti-slip matting must be applied to both sides of the full-width timbers between each row of tube bundles.

Other requirements remain the same.
