1DESCRIPTIONAND INTENDED USE
THIELE-Lashing points weld-type (type TWN 1472 and
TWN 1473) are intended for attachment to steel
structures to enable connections with lashing means.
(TWN = THIELE standard)
Weld-type lashing points mainly consist of two forged
weld-on supports and a forged ring.
Lashing points can be
loaded to 100 % in all
tensile directions.
The rings are marked with the maximum lashing capacity LC in daN (Deka-
Newton). (LC = Lashing Capacity)
The rings of TWN 1472 are red powder coated, the rings of TWN 1473 are blue
powder coated. The weld-on supports are not coated.
The lashing points feature a safety factor of at least 2 based on the maximum
lashing capacity.
Usage for lifting is not permissible!
The lashing points must exclusively be used
•within the limits of their permissible lashing capacity,
•within the temperature limits prescribed,
•with properly laid welding seams.
2SAFETY NOTES
Risk of Injury!
Make sure to use lashing means free from defects.
•Operators, fitters, and maintenance personnel must in particular observe this
Instructions also from the used lashing chain assemblies, documentation DGUV
V 1 issued by the German Employers’ Liability Insurance Association, as well as
the Operating Instructions of the vehicle.
•Outside the Federal Republic of Germany the specific provisions issued locally
in the country where the items are used must also be observed.
•The directions given in these Operating Instructions and specified
documentations relating to safety, assembly, operation, inspection, and
maintenance must be made available to the respective persons.
•Make sure these instructions are available in a place near the product during
the time the equipment is used. Please contact the manufacturer if
replacements are needed.
•When performing work make sure to wear your personal protective equipment!
•Improper assembly and use may cause personal injury and/or damage to
property.
•Assembly and removal as well as inspection and maintenance must exclusively
be carried out by skilled and authorized persons.
•Structural changes are impermissible (e.g. welding, bending).
•Visually inspect the equipment prior to each use.
•Never put to use worn-out, bent or damaged lashing points.
•Only lashing loads the mass of which is less than or equal to the capacity of the
lashing points.
•Do not use force when mounting/positioning the lashing points.
•Do not bend the ring.
•Only remove lashing means manually (use your hands).
•In the event of doubts about the use, inspection, maintenance or similar things
contact your safety officer or the manufacturer!
•Transportation of persons is forbidden!
THIELE will not be responsible for damage caused through non-observance of
instructions, rules, standards and notes indicated!
Working under the influence of drugs, medications impairing the sense and/or
alcohol (including residual alcohol) is strictly forbidden!
3COMMISSIONING

5WELDING INSTRUCTIONS
5.1 General #
Material of the weld-onsupport: S355NL or S355J2
Material of the weld-onjoint: C22, S235, S355 or similar
The following general welding instructions must be observed:
•EN ISO 2560 Welding consumables –Covered electrodes for manual arc
welding of non-alloy and fine grain steel
•EN ISO 14341 Welding consumables –Wire electrodes and weld
deposits for gas shield metal arc welding of non-alloy
and fine grain steel
•ISO 3834-2 Quality requirements for fusion welding of metallic
materials
•EN 1011-1, 2 Welding –recommendations for welding of metallic
materials
•EN ISO 9606-1 Qualification testing of welders –fusion welding
•DVS 0702-1 / 0711 Factsheet - Requirements for operation and personnel
•SEW 088 Weldable unalloyed and low-alloyed steels –
Recommendations for processing#
Welding is only permitted by trained and authorised personnel in accordance
with the qualification according to EN ISO 9606-1.#
The positions of the welds are marked red in the sketch:
Take care to intermit the weld seam in the
center on the outside to enable water to
flow out.
Welding on the movable ring is not allowed!
5.2 Preparations
Make sure the welding surfaces are grinded down, flat, dry, free of impurity,
flawless and weldable (material see ISO/TR 15608 table 1, group 1).
Make sure the mounting place is able to absorb the maximum specified lashing
capacity multiplied with a safety factor of 1,25 without safety reducing
deformation.
5.3 Requirements
The mounting location for each lashing point has to ensure that
•no areas of danger are created (crushing point, shearing point),
•transportation is not restrained by overhang,
•used lashing means (e.g. hooks) are freely movable and will not be bended,
•lashing accessories will not be bypassed,
•incorrect use is avoided,
•lashing points cannot be damaged,
•they can be reached easily and without obstruction for attaching and detaching
the lashing means. #
Observe the welding instructions listed.
The lashing points must be inspected by an expert after welding and before first
use. This inspection must be documented.#
5.4 Welding dimensions
Sketch:
5.5 Welding sequence
1. Check the suitability of the attachment location especially concerning to
stability, weldability and a safety use.
2. Position the lashing point and mark the position of the first weld-on
support.
3. Fix the first support and make the root run.
4. Clean the root run and make the final runs.
5. Position the ring with one end into the first support and then the second
support atop the free end of the ring. Consider and check dimension E.
Fix the second support by tack-welding.
6. Check dimension E and check the ring can move to 180 °.
Readjust the second support if necessary.
7. Weld the second support as the first one.
8. Check a smooth movement of the ring at last.
Do it analogously the same way for an assembly of single rings within a steel
construction.
5.6 Miscellaneous
1. Minimum notched-bar impact strength values of ISO-V specimens KV=27J at
-40 °C (e.g. S355J4G3 or S355NL, EN10025)
2. When selecting material grades other than those listed above please contact
the base material and filler metal manufacturers for information.
3. The responsible welding supervisor on site must make sure the welding
current is correctly adjusted to suit the given welding position.#
4. Check the welds for cracks, inclusions and blowholes.
5. A procedure check is recommended to confirm the selected settings.#

6CONDITIONSOFUSE
6.1 Normal use
The ring of the lashing point must always be freely movable.
It must not rest on or be supported by other structural parts.
6.2 Influence of temperature
The temperature range for use is -20 °C to +200 °C.
If the lashing points have been exposed to temperatures exceeding the maximum
values specified they must no longer be used.
6.3 Environmental influence
Lashing points must not be used in environments where acids, aggressive or
corrosive chemicals or their fumes are present.
Hot-dip galvanizing or a galvanic treatment is prohibited.
7INSPECTIONS, MAINTENANCE, DISPOSAL
7.1 Inspections
Inspections and maintenance must be arranged for by the owner!
Inspection intervals shall be determined by the owner!
Inspections must be carried out and documented by competent persons regularly
but at least once a year, or more frequently if the lashing points are in heavy-duty
service. After three years at the latest they must additionally be examined for
cracks. A load test shall never be considered a substitute for this examination.
The results of the inspection shall be entered into a register (DGUV I 209-062 or
DGUV I 209-063) to be prepared at first use. The register will show characteristic
data of the lashing points as well as identity details.
Immediately stop using lashing points that show the following defects:
•missing or illegible identification/marking,
•deformation, fractures, cuts, notches,
•limited articulation,
•heating beyond permissible limits,
•severe corrosion,
•wear exceeding 10 %, for example in the ring diameter area,
•weld failures.
7.2 Maintenance
Maintenance and repair work must only be performed by competent persons .
Minor notches and cracks at the rings may be eliminated by careful grinding
observing the maximum cross section reduction requirement of 10 % and avoid
making more severe cuts or scores.
All maintenance and repair activities are to be documented.
7.3 Disposal
All components and accessories of steel taken out of service are to be scrapped in
line with local regulations and provisions.
7.4 Inspection service
THIELE offers inspection, maintenance and repair services by trained and
competent personnel.
8STORAGE
Lashing points are to be stored in dry locations at temperatures ranging between
0 and +40 °C.
