Overview
ISO 19711-1:2018 - Building construction machinery and equipment - Truck mixers - Part 1: Terminology and commercial specifications provides standardized terminology and commercial specification requirements for truck mixers used to produce and deliver concrete or mortar. It applies to truck-mounted and semi-trailer mounted drum-type mixers and clarifies which machine types are excluded (for example, fixed/stationary mixers, turbo mixers, concrete mixing plants, small portable mixers, purpose-built underground truck mixers and volumetric mixers).
Key topics and technical requirements
This standard focuses on clear definitions and a consistent commercial data set to describe truck mixers. Key technical topics include:
- Terms and definitions for components and functions: truck mixer, mixer device, drum, drum fin, manhole, roller pedestal, drive pedestal, basic frame, working platform, charge/discharge devices, water system, control device, etc.
- Discharge and chute systems: definitions for swivel chute, flip-over chute, extension chutes and chute lock; Annex B gives a swivel chute example.
- Capacity and performance metrics:
- Rated drum capacity, rated agitating capacity, and rated mixing capacity (with illustrative figures).
- Maximum drum speed.
- Commercial specification fields to be presented by manufacturers or sellers:
- Mixer type, rated drum capacity.
- Overall vehicle dimensions: length, width, height, wheelbase.
- Specific heights and clearances: charge device height, chute end ground clearance, chute max height from ground.
- Complete vehicle kerb mass (per ISO 1176).
- Mixer device specifications:
- Mixer device dimensions, drum type, drum length and diameter, drum drive type (hydraulic, electric or alternative), water tank capacity, mixer device mass.
- Illustrative annexes: Annex A shows example mixer structures and dimensional drawings to support specification and procurement.
Applications and who uses this standard
ISO 19711-1 is valuable for:
- Manufacturers and OEMs specifying and marketing truck mixers (standardized datasheets and product descriptions).
- Fleet purchasers and rental companies comparing models on consistent criteria (capacity, dimensions, mass).
- Construction and concrete contractors specifying delivery equipment and site requirements (clearances, discharge types).
- Design, safety and maintenance engineers referencing component definitions (manhole, drive pedestal, water system).
- Regulators and standards committees aligning procurement and conformity assessment practices.
Using ISO 19711-1 improves interoperability, procurement clarity, and technical communication within the concrete delivery and construction equipment ecosystem.
