Overview
ISO 5050:1981 covers the general characteristics of continuous mechanical handling equipment specifically for vertical bucket elevators using calibrated round steel link chains as the traction element. Published in 1981 and developed by ISO/TC 101 with inputs from the European Materials Handling Federation (FEM), the standard defines fundamental requirements that support safe, reliable and interoperable elevator design.
The standard's scope addresses core parameters that influence elevator performance and selection: operating speed, envelope and component dimensions, bucket intervals (spacing) and casing configuration.
Key Topics
- Operating speed: Typical bucket speeds are specified in the standard and are generally in the range of 1 to 1.6 m/s, with the exact selection depending on the type of discharge (evacuation) used.
- Dimensions: ISO 5050 provides guidance on nominal dimensions for elevator components and references related dimensional standards (see Related Standards). It notes that nominal wheel diameters may apply only to embossed (toothed) wheels and that actual diameters depend on chain pitch and type.
- Bucket intervals: The interval between buckets is not fixed by a single value; instead, it must be determined by the manufacturer based on the transported material, required throughput (debit), bucket shape, chain pitch and operating conditions.
- Casing options: The standard allows for either single or double casing (gaine simple ou double), leaving the final choice to the manufacturer according to design and application needs.
- Permitted deviations: Where the material handled or operational conditions require it, deviations from standardized dimensions are permitted, recognizing practical needs in industry applications.
Applications
ISO 5050:1981 is intended for designers, manufacturers, specifiers and operators of vertical bucket elevators used in continuous material handling systems across industries such as bulk materials processing, agriculture, mining and bulk goods handling. Practical benefits include:
- Improved compatibility between elevator components and chains
- Clear baseline requirements for elevator performance and safety-related dimensions
- Guidance for selecting bucket spacing and speed tailored to material characteristics
Related Standards
- ISO 2148 - Nomenclature for continuous handling equipment (referenced by ISO 5050 for terminology).
- ISO 5051 - Dimensions for deep buckets with a flat back wall (ISO 5050 references bucket dimensions in ISO 5051).
- FEM (European Materials Handling Federation) documents - technical background and harmonization support used in developing ISO 5050.
Practical note: ISO 5050 establishes general characteristics rather than detailed fabrication rules. For final design, manufacturers and specifiers should combine the standard's guidance with detailed material data, chain pitch selection and site-specific operating conditions to ensure reliable, long‑life continuous handling installations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing Inter-
national Standards is carried out through ISO technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 5050 was developed by Technical Committee ISO/TC 101,
Continuous mechanical handling equipment, and was circulated to the member bodies
in May 1980.
