GOST 32885-2014 PDF

Full title and description

GOST 32885-2014 — Automatic coupler model SA-3 and its components. Design and dimensions (Автосцепка модели СА-3. Конструкция и размеры). The standard specifies the construction, principal parts and dimensional parameters of the automatic SA-3 coupler and the unified parts associated with it (traction yoke and wedge traction yoke).

Abstract

This interstate (GOST) standard establishes mandatory design features and dimensional requirements for the SA-3 automatic coupling used on railway rolling stock of the 1520/1524 mm gauge family. The document includes technical requirements, normative references and detailed illustrative appendices with construction drawings for the coupler body, lock, lock-holder, safety parts and traction yoke components.

Scope

The standard applies to the automatic coupling model SA-3 used on railway rolling stock and sets out required constructional features and exact dimensions for the coupler and its unified parts (notably the traction yoke and the wedge traction yoke). It is intended to ensure interchangeability, correct assembly and safe mechanical operation of coupling assemblies within the specified rolling-stock family.

Key topics and requirements

• Detailed construction and dimensional specifications for the SA-3 coupler and its components (body, lock, lock-holder, lock safety device, lifter shaft, bolts, nuts, etc.).
• Technical requirements for materials, manufacturing tolerances and machining relevant to coupler parts and castings.
• Assembly and interfacing dimensions to ensure compatibility with related coupling equipment and rolling-stock assemblies.
• Normative references to other GOST standards (hexagon nuts, bolts, castings, steel grades) and to related coupling device standards and test methods.
• Appendices containing construction drawings and dimensional tables for each major component (mandatory illustrative annexes).

Typical use and users

Primary users include rolling-stock manufacturers, coupler and component producers, maintenance and repair workshops, railway technical departments, certification and inspection bodies, and designers responsible for vehicle assembly and interoperability. The standard is used for design verification, procurement specifications and production control.
