Abstract

This standard establishes general technical conditions, performance and safety-related requirements, climatic and electrical characteristics, and testing/acceptance provisions for deck-mounted luffing-jib cranes with electric, hydraulic or electro-hydraulic drives. It includes references to related regulatory documents and replaces the earlier edition GOST 25938-83.

Scope

Applies to slewing deck-mounted luffing-jib cranes with variable jib reach (luffing jib) fitted to the open decks of seagoing vessels with unrestricted sailing area. Covered crane drive types include electric (КЭ), hydraulic (КГ) and electro-hydraulic (КЭГ) versions. The standard is intended for general-cargo handling cranes and sets requirements for design, manufacture, electrical equipment, climatic performance and operational limits (heel, trim, wind loads), as well as references to ship registry rules for lifting appliances.

Key topics and requirements

• General technical conditions for manufacturing and acceptance; compliance with ship lifting-device rules and referenced normative documents.
• Climatic and environmental performance classification (for marine service) — e.g., climatic execution OM per GOST 15150.
• Electrical equipment requirements for electrically driven cranes (designed for 380 V, 50 Hz where specified).
• Operational capability requirements under listed ship motions and attitudes (examples: heel up to 5°, trim up to 2°) and specified wind loading criteria (wind pressure values given in the standard).
• Reference and normative cross-references (includes ST СЭВ 3578-82 and related lifting-equipment documents).

Selected technical excerpts and performance limits are taken from the standard’s technical-requirements sections.

Typical use and users

Typical users are shipyards, crane manufacturers and designers, shipowners and operators specifying deck cranes for newbuilds or refits, classification societies and surveyors performing type-approval and periodic inspections, and regulatory/compliance teams responsible for marine cargo-handling equipment. The standard guides procurement, design verification, manufacturing and acceptance testing of deck-mounted luffing-jib cranes.

Related standards

References include regional and industry documents such as ST СЭВ 3578-82 and earlier national editions (this standard replaces GOST 25938-83). It also sits alongside other marine-crane and lifting-equipment standards and classification society rules for shipboard lifting devices.

FAQ

Q: What is this standard?

A: GOST 25938-90 is a national (USSR-origin) technical standard titled "Luffing-jib slewing deck-mounted cranes. General specifications" that sets general technical requirements for luffing-jib deck cranes intended for seagoing vessels.

Q: What does it cover?

A: It covers design/manufacture/acceptance provisions, electrical and climatic requirements, operational capability under specified heel/trim and wind loads, and references to ship registry rules and related normative documents.

Q: Who typically uses it?

A: Shipbuilders, crane designers and manufacturers, shipowners and operators, classification societies, marine surveyors and maintenance/inspection organisations involved with shipboard deck cranes.

Q: Is it current or superseded?

A: The standard was approved in 1990 and put into effect on 01 January 1991. It is listed in standards catalogues as the 1990 edition (10 pages) and is commonly referenced in normative collections; users should verify national adoption, any later national (GOST R / GOST) replacements or updates and classification-society rules that may have superseded or supplemented requirements for marine cranes.

Q: Is it part of a series?

A: It belongs to the set of GOST standards covering lifting equipment and marine/shipboard cranes and references regional standards (ST СЭВ 3578-82). It supersedes the prior GOST 25938-83 edition for the same subject.
