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.

5.1.5 Boom, slewing tower body, base and carrier structure
5.1.5.1 The main boom, jib, multifunctional boom, etc. shall adopt box shaped variable section boom
structure. The boom, slewing tower body, base and carrier shall be subjected to stress relief treatment
after welding.
5.1.5.2 The slewing tower body shall be subjected to watertight inspection.
5.1.6 Slewing mechanism
5.1.6.1 If there are special requirements for the slewing tower body to limit the slewing angle, the
mechanical and electric limits shall be set.
5.1.6.2 The slewing angle measurement shall be measured using an encoder enclosed inside a
hydraulic/electrical adapter.
5.1.6.3 The slewing mechanism has two slewing hydraulic drive mechanisms which are respectively
arranged on both sides of the lower plane of the slewing tower body. The slewing hydraulic drive
mechanism is composed of a planetary speed reducer, a brake and a gear, and the brake is normally
closed. The slewing hydraulic drive mechanism shall leave 1,5 mm eccentricity with the mounting axis
to ensure that the slewing support meshes well with the slewing hydraulic drive mechanism gear and
compensates for wear during use.
5.1.7 Fixed base/travelling mechanism
5.1.7.1 The fixed base shall be of sufficient rigidity to prevent the system from shaking due to excessive
elastic deformation.
5.1.7.2 For roller trains of the travelling mechanism, the two roller trains mounted on the front and
rear ends of the lower portion of the carrier respectively shall be used, each roller train consisting of one
mounting shaft, four positive rollers, four return rollers and two swing frames, to accommodate to the
vertical plane motion and horizontal yaw of the ship. Travelling drive should adopt the pinion and rack
driving mode.
5.1.7.3 The cable length of the cable reel on the travelling mechanism is one-half of the travelling
stroke of the travelling multifunctional manipu
