AS 2868-1986

Sets out the type and size of earthmoving machinery with consideration to both power and mass criteria. Where possible, classes have been made small enough to separate machines with significantly different productive output. Tables provide the class number in relation to net engine power, operating mass, digging depth, classifying load, static linear load, bowl capacity and classifying power.

This standard establishes a classification system for machines used in the earthmoving, construction, surface mining and agricultural industries, as follows:Machine Scope and Exclusions SectionAir compressors Portable, with free air delivery (FAD) >= 25 L/s 2Chain trenchers Self-propelled, with net engine power >= 5 kW 3Excavators (and shovel-loaders) Self-propelled, not including large mining excavators 4Graders All types 5Loaders: Backhoe ~ Rubber tyred and tracked 6 Front-end ~ Wheeled and tracked 7 Shovel ~ (and excavators) Self-propelled, not including backhoe attachments 4Rollers Static, vibrating, pneumatic and others 8Scrapers Standard and coal 9Tractors: Crawler ~ All types 10 Wheeled ~ All types, for construction and for agriculture 11NOTES:1. The classification by machine type and size provides a basis for purposes such as the following:(a) Setting operator wage rates.(b) Collection of data for statistics.(c) Establishing plant hire rates.2. This standard does not classify machines by noise levels, except for air compressors. Local Regulatory bodies may have specific requirements. For information on the assessment of noise levels, see AS 2221.3. Additional designations may be used where there are special or particular aspects of classification not covered by this standard.
