Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 8, Ships and marine technology,

Subcommittee SC 1, Maritime safety.

Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 24136:2021(E)
Ships and marine technology — Pilot ladder winch reels
1 Scope

This document specifies requirements and characteristics of ships’ pilot ladder winch reels provided

with hydraulic, pneumatic, electric, or manual drive. It is applicable to the design and test of pilot ladder

winch reels. It does not include requirements for the prime mover used to operate the pilot ladder

winch reels.

Pilot ladder winch reels specified in this document are intended to be only used with pilot ladders

conforming to ISO 799-1. They are not intended to be used for ‘man lifting’ activities.

2 Normative references

3.1
drum load
working load

maximum rope tension in the rope or ropes at the drum exit, when the pilot ladder winch reel is hoisting

an unloaded pilot ladder at the nominal speed, with the rope or ropes wound on the drum in a single

layer
3.2
holding load

in static mode of the pilot ladder winch reel, maximum rope tension in the rope or ropes at the drum

exit in the innermost layer with a minimum value of twice of the drum load (3.1)
3.3
left-hand pilot ladder winch reel

pilot ladder winch reel where the rope-out direction of the drum is on the left-hand side of the drum, in

relation to an observer situated on the side of reduction gearbox
