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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established 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.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
