Lashing Points for Welding

User Instructions

  1. Usage only by authorized and trained persons.
  2. Before each usage please check the Lashing Points in regard of cracks within the weld seam, strong corrosion, wear, deformations etc.
  3. The material construction to which the Lashing Point will be attached should be of adequate strength to withstand forces. The contact areas must be free from dirt, oil, colour etc. The material of the forged welding block is S355J2+N (St52-3,1.0577+N), B:S:4360.50 D or AISI 1019
  4. The quantity and the arrangement of the Lashing Points on vehicles have to be determined acc. EN 12640 or EN 75410 (for RoRo traf c; Roll-on - Roll-off) as long as the vehicles are not designated acc. their design and mechanism for the transport of speci c goods with special demands for load securing. The Lashing Points shall be arranged as wide as possible to use the full loading area and they should not protrude in steady position.
    Execute the position of the Lashing Points with the load in such a way that unacceptable stress like twisting or tilting will be avoided.

    Warning: Lashing Points must not be used for Lifting of loads.

  5. Determine the required, permitted Lashing Capacity acc. EN 12 195-1 „Load securing devices on road vehicles“ - calculation of Lashing Capacities and acc. VDI 2700. RUD-Lashing Points are marked at the welding block with the permitted lashing capacity „LC“ in daN.
  6. The Lashing device must be free moveable within the LPW. During hang up and unhinge of the lashing devices there must no crush, cutting or traps occur for the handling.
  7. Suitability of temperature use: RUD-Lashing points LPW are suitable for the temperature range from -20°C up to 400°C. For the use within the following temperature range, the WLL must be reduced by the following factors:
    200°C up to 300°C: by -10 % and
    300°C up to 400°C: by -25 %
    The Lashing points LPW can be stress-relieved one-time in an unloaded condition, together with the load (e.g. welded construction): Temperature < 600°C (1100°F) The evidence of the suitability of the used weld metal must be mentioned by the respective ller material manufacturer.
  8. Please make Lashing Point easy visible by using a contrasting colour as paint.
  9. The weld seam arrangement „continous HV-weld seam“ fullfils the requirements acc. to DIN 18 800 (structural steel works). At structural steel constructions in outdoor usage or especialy when corrosion endanger oc- curs, the weld seams must only be carried out as circulating , shut llet weld seams.
  10. The distance lugs assist in achieving the correct air gap for the root of seam weld (approx. 3 mm, or 1/8“) Lugs must not be removed!
  11. After welding, or sooner if conditions dictate, an annual inspection should be undertaken by a authorized person to check the continuance of the appropriateness.

Inspection criteria concerning paragraph 2 and 11:

  • Completeness of Lashing Point
  • Complete and readable marking of Lashing Capacity as well as manufacturer sign
  • Deformation at supporting structures like Basic Components and Lashing Rings
  • Mechanical damage like strong notches, particully in areas with tensile stress
  • Reduction of cross sectional diameter caused by wear > 10 %
  • strong corrosion (fittings)
  • Cracks on supporting structures
  • Cracks or any other damage of the weld seam

Warning: Failure to read, understand and follow the instructions, Lashing Capacity and speci cations in this and other RUD publications could result in serious injury or property damage!
