Continuous mechanical handling equipment - Bucket elevators - Classification
Establishes the classification, according to their principal characteristics, of various types of bucket elevators. Gives the following classifications: according to construction and to the path of the bucket, according to the type of discharge, according to the driving medium system and describes the common types of bucket elevators.

Overview
ISO 7190:1981 defines a clear, internationally recognized classification system for bucket elevators - a category of continuous mechanical handling equipment used for vertical or inclined transport of bulk materials. Rather than prescribing design or performance limits, the standard organizes bucket elevators by their principal characteristics (construction, discharge type, feeding method and driving medium) and describes the common types encountered in industry.
Key topics and classification criteria
ISO 7190 groups bucket elevators using practical, engineering-focused criteria:
- Construction / path of buckets
- Vertical straight bucket elevators (near-vertical paths)
- Inclined straight bucket elevators (approximately 55–70° to horizontal)
- Gravity bucket conveyors operating in a vertical plane (different levels in same plane)
- Type of discharge
- Centrifugal
- Mixed (centrifugal + gravity)
- Gravity - external
- Gravity - internal
- Feeding method
- External direct feed
- External scraping (dragging) feed
- Internal feed
- Driving medium / support
- Round-link chain
- Other chain types
- Belt
- Wire rope (cable)
The standard also describes common machine families and operational characteristics, including:
- Speed categories referenced in examples (e.g., high speed v > 1 m/s; slow speed v < 0.8 m/s; inclined ~v < 1 m/s; gravity conveyors ~0.5 m/s)
- Typical combinations such as centrifugal discharge with direct external feed, continuous buckets with chain drive, single or double casing, and positive discharge by deflecting sprockets.
Practical applications and users
ISO 7190 is useful wherever bucket elevators are specified, selected, manufactured, installed or maintained:
- Equipment manufacturers: to categorize product lines and provide standardized descriptions in datasheets
- Plant engineers and process designers: to select appropriate elevator types for bulk material handling (grain, minerals, aggregates, chemicals)
- Procurement and specification writers: to create unambiguous tender and purchase specifications
- Maintenance and safety teams: to identify elevator types for inspection, spare parts and lifecycle planning
- Standards developers and technical libraries: as a reference for nomenclature and classification in documentation
Practical benefits include improved communication across suppliers and users, clearer procurement specifications, and easier comparison of elevator types for a given material handling task.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bodies). 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 Iiaison 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 7190 was developed by Technical Committee ISO/TC 101,
Conthuous handling mechanical equipment, and was circulated to the member bodies
in July 1980.
lt has been approved by the member bodies of the following countries :
Australia Germany, F. R. South Africa, Rep. of
Austria Ireland Spain
Korea, Rep. of Sweden
Belgium
Chile Netherlands United Kingdom
