GOST 4121-96 PDF

Full title and description

GOST 4121-96 — "Рельсы крановые. Технические условия" (English: "Crane rails. Specifications"). The standard establishes technical requirements, dimensional profiles and acceptance/testing rules for steel crane rails of special profiles (types КР70, КР80, КР100, КР120, КР140) used for runways of overhead and gantry cranes.

Abstract

This interstate standard specifies geometric dimensions, mass per metre, chemical and mechanical requirements, inspection and testing methods, acceptance rules, and rules for transportation and storage for crane rails used in lifting equipment runways. It replaces earlier editions of the rail specification and is intended to harmonize rail manufacture and procurement across the participating states.

General information

• Status: Active / действующий (operational interstate standard, widely used in CIS markets).
• Publication date: Adopted 1996 (designation -96); date of official introduction into force: 01 July 2002.
• Publisher: Adopted by the Interstate Council for Standardization, Metrology and Certification (EASC); promulgated via national standards bodies (e.g., national Gosstandart/Metrology agencies).
• ICS / categories: ICS 45.080 (Rails and rail components / Railway engineering). ОКП/Классификаторы: related to railway/metal rolling categories.
• Edition / version: Designation GOST 4121-96 (interstate standard, original approval in 1996 with text entry into force 2002).
• Number of pages: Typically published as 8 pages in standard collections (format and pagination may vary slightly by publisher/print/electronic edition).

Scope

The standard applies to steel crane rails of special profiles of types КР70, КР80, КР100, КР120 and КР140 intended for the tracks of lifting cranes. It covers required profile geometry, dimensional tolerances, sectional areas and masses, material/steel grades, mechanical property limits, acceptance classes (wear groups), and requirements for testing, marking, packing, transportation and storage.

Key topics and requirements

• Defined profile dimensions, cross-section drawings and tabulated nominal sizes/masses for КР70–КР140 rails.
• Material and chemical composition requirements and referenced test methods (tensile, chemical sampling, hardness where applicable).
• Mechanical property requirements and permissible deviations; classification by wear groups for operational acceptability.
• Rules of acceptance, sampling plans and methods of testing (including referenced GOST/ISO test methods).
• Requirements for marking, packaging, transportation and storage to preserve rail condition prior to installation.
• Normative references to related standards used for testing, sampling and product handling (examples include standards on tensile testing, sampling of metal products, and acceptance/marking rules).

Typical use and users

Manufacturers of rail and rolling steel, foundries and steel mills producing crane rails; suppliers and distributors of metal products; designers and builders of overhead/gantry crane runways; maintenance and inspection teams in heavy industry, ports, warehouses and steelworks; procurement/specification engineers selecting rails for lifting equipment infrastructure.

Related standards

Preceding national standard: ГОСТ 4121-76 (replaced). Normative references within GOST 4121-96 include standards for mechanical testing and sampling (for example, standards equivalent to GOST 1497 and GOST 7565 / ISO-based test methods) and standards on acceptance, marking and storage of metal products. Related national/regional standards on rail steels and crane equipment design should be consulted in parallel.
