Overview
ISO 7135:2009 - Earth-moving machinery - Hydraulic excavators - Terminology and commercial specifications defines the standardized terminology and the required content of commercial literature for self‑propelled crawler and wheeled hydraulic excavators, their equipment and attachments. It establishes consistent definitions (e.g., excavator types, operating mass, shipping mass, attachments and equipment types) and prescribes the information manufacturers should include in specifications and product literature (in SI units).
Key topics and technical requirements
- Scope and applicability: Applies to crawler and wheeled hydraulic excavators and common components; excludes walking‑excavator‑specific terms.
- Terms and definitions (Clause 3): Standardized vocabulary for excavator elements (base machine, cab riser, transport/manoeuvring/travel positions), masses (operating mass with a 75 kg operator; shipping mass), equipment and attachments (hoe, shovel, grab, quick coupler, blade), and equipment types (telescopic boom, hoe, shovel, clamshell, swing‑type boom).
- Base machine (Clause 4): Classification by undercarriage (crawler, wheeled) and equipment; component nomenclature and base‑machine dimensions referenced to ISO 6746‑1.
- Equipment and attachments (Clause 5): Nomenclature, dimensions, and recommended positions for manoeuvring, road travel and shipping.
- Performance terminology (Clause 6): Standardized expression of parameters such as ISO net engine power, travel and swing speeds, braking and steering performance, digging forces and rated lift capacities.
- Commercial literature specifications (Clause 7): Required specification content for engine, hydraulic system, fluid capacities, filtration, crawler and wheeled excavator particulars, operating and shipping masses (in SI units).
- Normative annexes: Annex A and B provide base‑machine and attachment dimension references (normative).
Practical applications - who uses ISO 7135:2009
- Manufacturers - to prepare consistent product data sheets, manuals and sales literature.
- Procurement and fleet managers - to compare machines on equivalent, standardized terms (operating mass, shipping mass, lift capacities, dimensions).
- Engineers and designers - for integration, transport planning and equipment selection.
- Rental companies and dealers - to create accurate spec sheets and ensure interchangeability of attachments.
- Standards bodies and test laboratories - as a reference when aligning tests and reporting results.
