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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT) see the following URL: Foreword - Supplementary information

INTERNATIONAL STANDARD ISO 16855:2013(E)
Ships and marine technology — Loose gear of lifting
appliances on ships — General requirements
1 Scope

This International Standard specifies the general requirements for loose gear of lifting appliances on

ships.
This International Standard is applicable to lifting appliances on ships.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
loose gear

gear which is not permanently attached to the lifting appliances, such as chains, triangle eyeplates,

hooks, blocks, shackles, swivels, sockets, preventer guys with patent clips, and rigging screws

Note 1 to entry: Lifting beams, spreaders, frames, and similar items of equipment are also regarded as loose gear.

2.2
safe working load
certified load for which the component has been designed and tested

Note 1 to entry: This certified load should be not less than the maximum load to which the component will be

subjected when the appliance of which it forms part is operating at its SWL.
3 Technical requirements
3.1 Materials

3.1.1 Loose gear, such as hooks, lifting eyes, swivels, and shackles shall not be made of cast iron or cast

steel.

3.1.2 Forgings shall be normalized or normalized and tempered or otherwise heat-treated according to

a method appropriate to the properties of materials. Shackle materials shall use solid steel manufactured

by Martin furnaces, electric furnaces, or oxygen top blown converters; it is recommended to use the

electroslag remelting process.
3.2 Blocks

3.2.1 Blocks shall be so constructed to minimize the clearance between sheaves and enclosure

partition plates to prevent ropes from jamming.

3.2.2 Effective lubricating shall be maintained to the blocks during operation. Provision shall be made

for lubricating all bearings and swivel head fittings without dismantling the block.

3.2.3 Snatch blocks shall not be used in the lifting appliance systems.

3.2.4 The ratio of sheave diameter measured at the bottom of rope groove to the diameter of rope shall

not be less than that as given in Table 1.

Fibre ropes 6
3.3 Other technical requirements

3.3.1 “C” type hooks shall be so designed as to prevent the risk of the hook from catching on the ship’s

structure or other obstruction when hoisting by means of a hook shelter. Hooks for special purposes, such

as for lifting freight containers, shall comply with the appropriate recognized International Standards.
