4 lifting appliances on board ships intended for load handling within and outside ships while in theharbour and within ships while at ) Industrial lifting appliances : lifting appliances onshore and offshore, not covered by a) and dnvgl ST note:The main purpose of the lifting appliance will define the category of the lifting appliance and relevant applicable Each lifting appliance has its separate intended functions. Examples of intended functions are, butnot limited to: loading and discharging of ships handling of provision, store and spare parts, cargo hoses, gangways and ammunition handling of Suez Canal boats and search lights conveyance of persons/personnel handling of ramps and moveable cargo decks Requirements presented herein are minimum requirements to be satisfied, although subject toacceptance by the Society, other minimum requirements may be agreed based on new technologyavailable at the time of application for The requirements of this Standard may be supplemented with additional requirements whereinstallation of specific design or assessment shows that standards that provides equivalent or higher level ofintegrity and safety are more The Standard consists of a three level hierarchy of documents: and provides principles and procedures of the Society's classification, certification, verificationand consultancy DNVGL-ST-0377 .

Appendices, provides proven technology and sound engineering practice as well as guidance for the higherlevel documents mentioned in this This Standard distinguishes between: information and description of services , these two subjects are separated, and the Standard is divided into three parts: - : General information, application, definitions and references. Description of applicableservices and relations to rules and regulation from institutions other than the Society. - : Requirements and technical provisions. This Standard shall be applied for certification of shipboard lifting appliances for vessels with classnotation Crane. This Standard may also be applied as voluntary basis for verification and certification oflifting appliances that are not classed with the note:The Standard may also be applied to industrial The requirements presented herein should be applied consequently from concept design through thefinal construction, including major Specifications of the services provided by this Standard are given in [ ] and [ ].

6 The Standard does not apply to launching appliances for LSA, launching gear for diving equipmentand ROVs, structural parts of ramps and car decks, dredging appliances , which are no loading gear, personnellifts (elevators), jacks, overhead drilling equipment, fork lifts, portable hoisting gear Personnel lifting with cranes otherwise designed for lifting of loads/cargo may be covered Without prejudice to [ ], deviations from the requirements given in this Standard may onlybe substituted where shown to provide an equivalent or higher level of integrity or safer than under At the Society s discretion equivalent solutions and exemptions from the requirements given in thisstandard may be In case of conflict between requirements given in this Standard and a reference document, therequirements given in this Standard shall Where reference is made to codes other than the Society's documents, the valid revision shall betaken as the revision which was current at the date of issue of this Standard , unless otherwise DNVGL-ST-0377 .

8 (Examples are HELDK, Crane, E0 and F-AMC).Guidance note:E0 means that the vessel complies with requirements for having unattended machinery space and F-AMC means that the vesselcomplies with requirements for additional fire protection, in this case both for accommodation, machinery space and cargo Ship type notationCode used by the classification societies to define a type of vessel related to its most typical service. (Tankerfor oil, Passenger ship and Crane vessel are typical examples). Automatic overload protection system (AOPS)A system that automatically safeguards and protects the crane against overload and over-moment duringoperation by allowing the hook to be pulled away from the crane in order to avoid significant Certificate of conformityA document attesting that a product or service is in conformity with specific standards or technicalspecifications. (ISO Certification - Principles and practice. , 1980). Issued by manufacturer or Competent person/bodyPerson or body possessing knowledge and experience required for performing thorough examination and testof lifting appliances and loose gear, and who is acceptable to the competent DNVGL-ST-0377 .
