Specifies a test method to measure the drawbar pull performance of all self-propelled earth-moving machinery (except excavators) and their combination with mounted or trailed equipment, with or without payload. Covers the following criteria measured against travel speed: drawbar pull, drawbar power, and wheel or track slip.
Abstract
Overview
ISO 7464:1983 - "Earth‑moving machinery - Method of test for the measurement of drawbar pull" - specifies a standardized test method to measure the drawbar performance of all self‑propelled earth‑moving machinery (except excavators) and their combinations with mounted or trailed equipment, with or without payload. The standard covers measurement and reporting of drawbar pull, drawbar power, and wheel or track slip as functions of travel speed, and defines test sites, apparatus and calculation procedures.
Key topics and technical requirements
- Scope and exclusions: Applies to self‑propelled earth‑moving machines except excavators. Tests cover machines with mounted or trailed equipment and optional payload.
- Test variables measured:
- Drawbar pull (horizontal towing force, kN)
- Drawbar power (kW - product of travel speed and drawbar pull)
- Wheel/track slip (percentage difference between loaded and unloaded drive wheel/sprocket revolutions)
- Test site & surface:
- Recommended minimum straight test length: 100 m with approach/turning areas.
- Grade should be
