Overview
ISO 2140:1975 is an international standard developed by the International Organization for Standardization (ISO) that specifies essential dimensions for the construction of apron conveyors used in continuous mechanical handling of loose bulk materials. This standard focuses on defining the key measurements such as the pitch of the chain, width of the apron, and height of cheek plates to ensure consistency and interoperability in conveyor design. It also provides practical examples to guide engineers and manufacturers in applying these specifications effectively.
Appliance of ISO 2140:1975 enables improved efficiency and reliability in bulk material handling systems, which are critical in industries such as mining, agriculture, and manufacturing.
Key Topics
Pitch of Chain (P): The standard defines specific increments for the chain pitch including 63 mm, 80 mm, 100 mm, up to 500 mm. This dimension controls the spacing between links in the conveyor chain and impacts the conveyor's capacity and speed.
Width of Apron (B): Widths range from 160 mm to 2500 mm, accommodating various conveyor sizes and bulk material volumes. Choosing the correct width is crucial for optimal load-carrying capacity and stability.
Height of Check Plates (H): Heights vary from 40 mm up to 500 mm, corresponding to the size and nature of the bulk materials being conveyed. Check plates help retain the load on the conveyor apron.
Width of Track: Although not standardized due to varying load types and wheel fixings, the width of the track depends on the width of the apron and the conveyor design specifics.
Preferred Number Series: The standard allows the use of R10 or R20 series preferred numbers for dimensions, aligning with ISO 3 to ensure compatibility with existing engineering practices.
Practical Examples: Illustrated examples within the standard demonstrate common configurations to assist engineers in design and implementation.
Applications
ISO 2140:1975 is primarily applied in the design and manufacture of apron conveyors used for handling loose bulk materials such as minerals, ores, grains, and other granular products. Typical applications include:
Mining Industry: Transporting minerals and ores efficiently from extraction points to processing facilities.
Agriculture: Moving bulk grains, seeds, and fertilizers safely and reliably.
Manufacturing Plants: Handling raw materials and semi-finished bulk products during production.
Material Handling Systems: Integration into conveyor networks for continuous, automated bulk transport.
By adhering to ISO 2140 specifications, companies can design apron conveyors that ensure:
Compatibility between parts and equipment across different manufacturers.
Enhanced durability and lower maintenance through optimized component dimensions.
Increased operational efficiency with conveyors tailored to the bulk material characteristics.
Related Standards
ISO 3 (Preferred Numbers): Defines series of preferred numbers used in ISO 2140 for dimensional standardization.
ISO 527 (Mechanical Handling Equipment - Cranes): While not directly related, applies to handling equipment which may integrate conveyor systems.
ISO 15223 (Medical Devices – Symbols): Relevant for conveyor systems in medical supply logistics.
Other ISO standards on bulk materials handling: Including belts, screw conveyors, and bucket elevators that complement apron conveyors in bulk handling operations.
Conclusion
ISO 2140:1975 provides a foundational framework for standardizing the construction dimensions of apron conveyors in the bulk materials handling industry. It enables manufacturers and designers to create compatible and efficient conveyor systems by specifying standard chain pitches, apron widths, and check plate heights. Utilizing ISO 2140 not only ensures industry conformity but also promotes operational excellence through proven practical design examples. Adopting these standards helps facilitate smooth material flow in industries reliant on continuous bulk material transport.

Committee lSO/TC 101 has reviewed ISO Recommendation R 2140 and found it
technically suitable for transformation. International Standard ISO 2140 therefore
replaces ISO Recommendation R 2140-1971 to which it is technically identical.
