Introduction
This document is a harmonized standard to provide one means for container handling spreaders for
cranes to conform with the essential health and safety requirements of the Machinery Regulation, as
mentioned in Annex ZA.
This standard is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards, for machines that have been designed and built according to the requirements of this type-C
standard.
prEN 15056:2025 (E)
1 Scope
This document specifies safety requirements for spreaders used with cranes designed for the purpose of
handling freight containers, e.g. those based on ISO 668:2020. The connection between the spreader and
the container is by the use of twistlocks that engage into the container’s upper corner castings.
This document deals with all significant hazards, hazardous situations or hazardous events relevant to
container handling spreaders, when it is used as intended and under conditions of misuse which are
reasonably foreseeable by the manufacturer.
The spreader is interfaced to the crane’s control and safety system.
This document does not cover the following types of spreaders:
— hand operated spreaders (without external power supply);
— bottom lift grapple spreaders used for swap bodies and road trailers.
This document does not deal with the lifting of persons.
This document is not applicable to container handling spreaders manufactured before the date of its
publication.

4 Safety requirements and/or protective measures
4.1 General
The spreader shall comply with the safety requirements and/or protective measures of this clause. In
addition, the spreader shall be designed according to the principles of EN ISO 12100:2010 for relevant
but not significant hazards, which are not dealt with by this document.
4.1.1 Safety related functions
All safety related functions of control systems shall fulfil requirements of EN ISO 13849-1:2023 in the
following way:
— control circuits built with electromechanical, hydraulic and pneumatic components shall fulfil
Performance Level c and category 1;
— control circuits built with electronic or programmable components, respectively, shall fulfil
Performance Level c and category 2.
NOTE For spreaders in high-risk applications, as specified in 5.9 of EN 13135:2013+A1:2018 and EN 13001-
2:2021, a higher performance level can be required.
Container handling spreaders shall include the following safety related functions:
— detection of spreader twist lock condition “locked” and “unlocked” and prevention of lifting when
twist lock positions are not equal in all twistlocks;
— detection of landing of spreader on the container and prevention of the rotation of the twistlock when
the spreader is not in the landed condition.
prEN 15056:2025 (E)
4.1.2 Suspending (by passing) of safeguarding
Suspending a safety function or protective measure may be temporarily applied for setting, testing,
maintenance and emergency purposes.
The provisions specified in EN 60204-32:2008, 9.2.4 shall apply.
Where means for temporary suspension of safeguarding is provided, the device for suspending shall be
located inside an enclosure, access to which requires special tools, or other device not available for
normal operation, such as a key-operated switch, shall be provided.
4.1.3 Spreader with single point suspension
Spreaders with single point suspension shall have a possibility to horizontal shift to avoid loss of stability
and avoid inclination of spreader and container.
4.2 Requirement for strength
4.2.1 Structural
Container handling spreader shall be designed and constructed in such a way as to prevent failure from
fatigue and wear, taking due account of their intended use and any reasonably foreseeable misuse.
Structural failure as a cause of dropping the load shall be prevented by design of the load carrying
elements in accordance with EN 13001-1:2015, EN 13001-2:2021 and EN 13001-3-1:2012+A2:2018.
NOTE EN 13001 series is based on nominal stress method. More accurate alternative methods, such as finite
element analysis or strain gauge measurements, can be used in case of localized stress concentrations.
When designing the spreader, the effect of various loading and container length shall be taken into
account.
The spreader shall be designed in accordance with the following parameters, which shall be specified:
— container type(s) to lift;
— maximum load;
— dynamic coefficient when hoisting the load;
— load spectrum;
— number of lifting cycles;
— degree of unevenly loaded containers;
— maximum operating position deviation from horizontal level, e.g. trim, list/tilt (Figure 2);
— the description of the intended use of the spreader (see EN 13001-1:2015, 4.3.2 and Figure B.1 in
Annex B of this document) including features e.g. micro motion, skew (Figure 2).
If no other specifications for loading is available, the assumptions of loading given in Annex B shall be
used.
prEN 15056:2025 (E)
4.2.2 Connection to the crane
The mechanical connection system between sheaves or head block and spreader shall have a manual
positive locking device (e.g. a pin thru holes secured by a retained socket) or a powered locking device
with electrical indication of connection. Electrical indication shall be placed on the spreader when the
connecting action is done from the spreader.
4.2.3 Telescopic motion
Proof of competence of hydraulic cylinders shall be in accordance with EN 13001-3-6:2018+A1:2021.
For other components, the load effects and required life (number of cycles) shall be derived from the
service and load conditions mentioned in 4.2.1 and they shall not exceed the specified limit states.
NOTE For information regarding bearings, see EN 13001-3-4:2018.
4.3 Twistlock system
4.3.1 General
The spreader condition “landed” shall be indicated. Landing indication means that all twistlocks are in
the correct position in the corner castings.
The spreader twistlock condition locked and unlocked shall be indicated. Locked and unlocked indication
means that all twistlocks are in the indicated position. This is achieved by indicators at each twistlock or
by indicators on the mechanical connection between the twistlocks. The mechanical connection shall
ensure simultaneous movement of the connected twistlocks.
4.3.2 Twistlock
Geometrical tolerance
