Terminations for steel wire ropes - Safety - Part 4: Metal and resin socketing
This document specifies the minimum requirements for the molten metal and resin socketing of steel wire ropes within the scopes of EN 12385 4:2002+A1:2008, EN 12385 5:2002, EN 12385 6:2004,
EN 12385 7:2002, EN 12385 8:2002, EN 12385 9:2002 and EN 12385 10:2003+A1:2008.
The document is applicable only to those requirements that ensure that the socketing is strong enough to withstand a force of at least 100 % of the minimum breaking force of the rope (i.e. socket termination efficiency factor KT = 1,0).
NOTE Rope terminations made by socketing in accordance with this document can be used for determining the breaking force of wire ropes in accordance with EN 12385 1:2002+A1:2008, Annex A.
Socketing by the methods and materials described in this standard are for use within the temperature limits given in normative Annex E.
This document deals with all significant hazards, hazardous situations and events relevant to metal and resin socket terminations, when they are used as intended and under conditions of misuse which are reasonably foreseeable (see Clause 4).

Introduction
This document is a type C standard as stated in EN ISO 12100.
The procedures concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type B standards,
the provisions of this type C standard take precedence over the provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
The methods of socketing described in this standard are based on established procedures and following
them is considered to result in a rope termination having an efficiency of 100 % based on the minimum
breaking force of the rope.
It is assumed that the socket is:
— suitable for heating without changing the characteristics of the socket material when the socketing
medium is molten metal;
— strong enough for the rope;
— suitable for the purpose for which it is intended.

4 List of significant hazards
This clause contains all the significant hazards, hazardous situations and events for the molten metal
and resin socketing of steel wire ropes within the scopes of EN 12385-4:2002+A1:2008;
EN 12385-5:2021; EN 12385-6:2004; EN 12385-7:2002; EN 12385-8:2002; EN 12385-9:2002 and
EN 12385-10:2003+A1:2008, as far as these hazards are dealt with in this document, identified by risk
assessment as significant for socket terminations that require action to eliminate or reduce risk.
In particular, the hazard caused by accidental release of a load due to failure of the socketed portion of a
socketed rope termination puts at risk, either directly or indirectly, the safety or health of those persons
within the danger zone.
In order to provide the necessary strength of the socketed portion of a socketed termination, this
document gives requirements for the method of socketing to ensure specified levels of performance are
met.
Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being
specific and significant for socketed termination assemblies.

5.1 General
Procedures shall comply with the safety requirements and/or protective measures of this clause.
In addition, the rope assembly terminated in accordance with this document and which is designated
for lifting purposes shall be designed in accordance with the principles of EN ISO 12100 for relevant but
not significant hazards which are not dealt with by this document.
Socketing shall be carried out by a person trained in socketing.
5.2 Preparation of rope and socket
5.2.1 General
The position of the wires and strands of the non-socketed portion of rope shall remain undisturbed
during the socketing operation. Temporary servings or, alternatively, a mechanical device, e.g. clamp(s),
may be used for this purpose.
5.2.2 Length marking of rope
The rope shall be marked with the required length taking into account the length of the socket basket,
the length of the brush to be formed, any additional brush length for the hooking of wires and, if used,
the depth of any centralizing clamp.
5.2.3 Serving
Temporary servings shall be used to hold the strands and wires in position during the cutting operation.
Temporary servings shall also be used, when required by nature of the rope construction, e.g. spiral
rope, to maintain the lay of the rope etc. beyond the portion being socketed.
The rope shall be served with a permanent serving as shown in Figure 2. The permanent serving shall
be in position before cutting the rope. Unless specified otherwise by the socket manufacturer, the
serving shall allow for penetration of the socketing medium between the served rope and the bore of
the socket.
10
---------------------- Page: 12 ----------------------
SIST EN 13411-4:2022
EN 13411-4:2021 (E)
The material used for the permanent serving shall be tinned or galvanised soft wire or strand for
zinc/zinc alloy coated wire rope, and uncoated (bright), tinned or galvanised soft wire or strand for
uncoated (bright) wire rope.
5.2.4 Cutting of rope
The wire rope shall be cut by abrasive wheel, percussive or shearing methods, paying particular
attention not to disturb the position of wires and/or strands below the permanent serving.
If oxyacetylene or cutting methods that fuse the wire rope end – i.e. fuse and taper machine – are used,
then the rope shall be trimmed back with a disc cutter to remove the heat affected zone.
5.2.5 Cleanliness of socket
Dirt, grease, scale or residues shall be removed from the inside of the socket basket.
NOTE This does not preclude the use of a releasing agent when socketing with resin.
5.2.6 Inserting rope into socket
One of two procedures shall be used to insert the rope into the socket.
In the first method, the rope shall be inserted into the socket prior to the preparation of the brush.
In the second method, after the brush has been prepared in accordance with 5.2.8 to 5.2.10, it shall be
closed and compacted to enable it to be inserted by way of the bore into the socket basket without
damaging the rope.
5.2.7 Opening the brush
The temporary serving at the point of cut shall be removed and the strands fanned outwards to
facilitate the brushing operation.
The rope (including any steel core where appropriate) shall be unlaid into its constituent wires to form
an open brush (see Figure 2).
The opening angle of the brush should not exceed 45° from the vertical (see Figure 2).
Wires should not be bent to an excessive angle at the permanent serving, since this can adversely
influence the life of the socket assembly. Special care should be taken with locked coil rope due to the
sensitivity of the full lock wire section.
Any fibre core and/or non-metallic components, e.g. plastic covering or plastic in-fill, shall be removed
from the whole length of the brush if possible, but at least over 4/5 of the brush length.
When socketing fibre core ropes using molten metal, the exposed end of the fibre core shall be
protected from the effects of heat created by the molten metal so that the fibre core material does not
ignite, melt or otherwise burn, smoke or smoulder. One method to achieve this may be to replace the
fibre core with a false steel rope core over a length of 15 × rope diameter (15d) beyond the socket
and > 1d inside the socket.

5.2.8 Pre-treatment of the brush
The brush shall be degreased to remove all traces of lubricant. Degreasing shall be by either liquid or
vapour methods. It is essential that when using solvents the solvent manufacturer’s instructions are
followed.
Care shall be taken to ensure that degreasing is confined to the brush.
The wire brush shall be completely dry before the socketing medium is poured into the socket.
When socketing with lead-based alloys the wires of a bright rope may be pre-treated for improved
adhesion. An optional procedure is given in Annex D (informative).
5.2.9 Hooking
Where type testing shows that hooking is necessary, the dimensions and shape of the hooked portion
shall be limited such that it shall not impede the flow of the molten metal or resin during socketing, nor
reduce the embedded length of the brush in the socketing medium.
NOTE Ropes with coarse constructions i.e. 1 × 7, normally require hooking to ensure compliance with this
document.

5.2.10 Positioning and alignment of brush, rope and socket
The brush shall be re-shaped into a form approximating the shape of the socket basket.
The socket shall be drawn over the brush until the root of the brush protrudes into the tapered portion
at the small end by no more than 0,5 d.
The wires shall be evenly distributed within the socket basket.
The distance between the end of the brush and the large end of the socket basket shall be no greater
than 5 % of the length of t
