Описание (английский):

Specifies a procedure for approximating the volume of typical materials contained in the bowl of open bowl scrapers. The volumes are based on the inside dimensions of the bowl and representative volumes on top of the bowl. This rating method is intended to provide a consistent means of comparing capacities; it is not intended to define actual capacities that might be observed in any specific application.

Overview

ISO 6485:1980 defines an internationally recognized procedure for the volumetric rating of tractor-scrapers used in earth-moving machinery. This standard provides a consistent method to approximate the volume of materials contained within the bowl of open bowl scrapers by measuring the inside dimensions and accounting for representative heaps on top of the bowl. The primary purpose of this volumetric rating method is to enable uniform comparison of scraper capacities under standardized conditions rather than to specify actual operational capacities.

Developed by ISO Technical Committee ISO/TC 127 on Earth-moving Machinery, this standard ensures that manufacturers, operators, and engineers have a reliable and repeatable procedure to assess and communicate scraper bowl volumes for design, purchasing, and operational planning.

Key Topics

Scope and Application ISO 6485:1980 applies exclusively to open bowl scrapers and defines how to measure the struck (inside bowl) volume and the top (heaped) volume based on fixed dimensional boundaries. It includes specifications for positioning bowls, closing aprons, and accounting for various geometric features.

Volumetric Measurement Procedure

Position the scraper bowl with the floor as horizontal as possible.
Fully retract the ejector and close the apron tightly to minimize gaps.
Define the struck volume within the interior surfaces of the apron, cutting edge, bowl floor, ejector, and sides.
Establish boundary planes using a 1:1 slope (45°) from top apron edges and mean lines for calculating volume boundaries.
Add the top volume by projecting planes of 45° slope above the struck volume to account for heaped soil typically retained during operation.
Ignore local features such as gussets or apron arms in volume calculations.

Expression of Ratings

Volumes under 10 m³ are reported to 0.1 m³ precision.
Larger volumes are expressed to 0.5 m³ precision.
Published ratings must be within ±3% of volumes determined by the ISO method.

Definitions and Components

Defines "open bowl scraper" and key components such as the apron, ejector, cutting edge, floor, and bowl sides to standardize measurement.

Applications

Equipment Specification and Comparison Enables manufacturers and buyers to compare scraper bowl volumes uniformly, facilitating informed decisions when selecting earth-moving machinery for construction, mining, and civil engineering projects.

Design and Performance Evaluation Provides engineers and designers with standardized volumetric references for scraper bowls, aiding in optimizing load capacities, power requirements, and operational efficiency.

Operational Planning Helps fleet managers and contractors estimate material handling capacities of tractor-scrapers under consistent conditions for project scheduling and cost estimation.

Regulatory and Certification Use Serves as a reference method in procurement, certification, and compliance assessment for earth-moving machinery capacities across different countries and markets.
