GOST 33718-2015 PDF

Full title and description

GOST 33718-2015 — "Cranes. Wire ropes. Care and maintenance, inspection and discard". National (interstate) standard that sets requirements and procedures for the handling, maintenance, inspection and removal-from-service of steel wire ropes used on cranes (including floating and offshore cranes).

Abstract

This standard provides guidance and mandatory criteria for safe care, storage, installation, running‑in, routine and periodic inspection, maintenance, record‑keeping and discard of crane wire ropes. It establishes inspection intervals and practical discard criteria (visible broken wires, reduction in diameter, corrosion and deformation), recommends inspection methods (visual and supplemented methods), and includes recommended forms and protocols for documenting inspections and decisions to re‑use or discard ropes. The standard aligns with international practice for crane wire‑rope safety and maintenance.

Scope

The standard applies to steel wire ropes used on all types of cranes and hoisting equipment covered by national crane standards, including stationary, mobile, floating and offshore cranes. It covers rope care (unloading, storage, transport), installation and running‑in, daily and periodic inspection procedures (including special attention to terminations and areas near end fittings), maintenance actions (lubrication, closing/repair), criteria and methods for discarding rope from service, and documentation formats for inspection records. It is applicable for both operational safety management and for use in conformity assessment and technical oversight contexts.

Key topics and requirements

• Definitions and classification of rope terms, nominal and actual diameters and rope categories.
• Care and handling: unloading, storage, protection against corrosion and mechanical damage, correct ways to lift and reel ropes.
• Installation and running‑in procedures to ensure correct seating on drums and sheaves and to minimise early internal damage.
• Routine (daily/shift) visual inspections and detailed periodic inspections — scope, frequency and techniques.
• Inspection of critical zones: terminations, splices, near attachments and over blocks or drums.
• Discard criteria based on: number of visible broken wires over reference lengths (e.g., per 6d and 30d, where d = rope diameter), loss of diameter, severe corrosion, kinking, deformation, core deterioration and other damage types.
• Maintenance actions — lubrication, closing of strands, recommended repair/temporary measures and handling after inspection.
• Recording, reporting and recommended forms/protocols for single and periodic inspections; responsibilities of competent personnel.
• Reference to and alignment with relevant international standards and safety regulations (practice consistent with ISO guidance on wire‑rope care and discard).

Typical use and users

Primary users are crane owners and operators, maintenance and inspection personnel, lifting equipment safety officers, accredited inspection bodies, plant safety managers, lifting equipment designers and manufacturers, and regulatory authorities involved in conformity assessment and occupational safety. The standard is used as a technical reference for routine maintenance programmes, pre‑use checks, periodic condition assessments and decision‑making on rope replacement.

Q: What does it cover?

A: It covers handling and storage, installation and running‑in, daily and periodic inspection procedures, maintenance practices (including lubrication and closing), discard criteria (visible broken wires, diameter loss, corrosion, deformation, core condition) and forms for documenting inspections and decisions to retain or replace ropes.

Q: Who typically uses it?

A: Crane owners and operators, maintenance crews, lifting‑equipment safety officers, inspection bodies, certification and conformity assessment organizations, manufacturers and designers of lifting equipment.

Q: Is it current or superseded?

A: The document is the 2015 edition (GOST 33718-2015) and is published as an active standard in national/interstate registries; consolidated versions may include later amendments. Users should check the national standards registry or the publishing authority for the latest consolidated text and any subsequent amendments or replacements before application.

Q: Is it part of a series?

A: Yes — it is part of the suite of crane standards (vocabulary, selection of ropes/drums/sheaves, crane requirements) and aligns with international standards on rope care and discard (ISO 4309 and related ISO/IEC crane standards).
