Overview
ISO 7132:2003/Amd 1:2018 is an important amendment to the international standard covering earth-moving machinery, specifically dumpers. This amendment updates terminology and commercial specifications relevant to dumpers used in construction and earth-moving industries. Developed by ISO Technical Committee ISO/TC 127, Subcommittee SC 4, the standard ensures consistent definitions and clear specifications which facilitate communication, procurement, and compliance within the global earth-moving machinery sector.
This amendment refines definitions and classifications of dumpers, including articulated and rigid chassis types, as well as the inclusion of tracked dumpers and motobasculeurs (compact dumpers). It also revises key performance terms such as unloading cycle time and wheel force specifications, thereby improving clarity on machine capabilities and requirements.
Key Topics
-
Updated Definitions for Dumpers
The amendment clarifies terminology around various types of dumpers:
- Rigid chassis dumpers - Machines with fixed chassis and steering via wheels or tracks.
- Articulated chassis dumpers - Dumpers with articulated frames for improved maneuverability.
- Tracked dumpers - Introduces tracked versions for improved terrain handling.
- Motobasculeurs - Compact dumpers with integrated self-loading capabilities, limited by weight.
-
Performance Terms
Revised and newly introduced terms include:
- Effort at the rim - the driving force between tires or tracks and the ground.
- Duration of empty dumping cycle - total time to complete an empty cycle including unloading and return.
- Definitions breaking down the dumping time into unloading and return phases.
-
Commercial Specifications and Dimensions
The amendment details standardized dimensions and measurement codes for dumpers, including new codes such as L7 for track ground contact length and W5 for superstructure width. Figures illustrate operator positions and chassis configurations to follow consistent classification.
-
Terminology Consistency
Terminology updates ensure harmonization with other ISO standards such as ISO 6165, enhancing the coherence of earth-moving machinery vocabulary internationally.
Applications
ISO 7132:2003/Amd 1:2018 is highly relevant for manufacturers, suppliers, and users of dumpers in the construction, mining, and earth-moving industries. It serves to:
-
Standardize Equipment Specifications
Facilitates clearer procurement terms and reduces ambiguity in machine descriptions and performance expectations.
-
Improve Design and Safety
Provides manufacturers with unified definitions that assist in design conformity and regulatory compliance.
-
Aid Technical Communication
Ensures consistent use of terminology across international markets, easing negotiations and documentation.
-
Support Training and Operation
Enables operators and technicians to better understand machine types and performance metrics, fostering safer and more efficient equipment use.
