This SAE standard includes hydraulic backhoes which have no more than 190 degrees of rotational swing and are mounted on wheeled tractors and crawler tractors. Illustrations used are not intended to include all existing commercial machines or to be exact descriptions of any particular machine. The illustrations have been chosen to describe the principles to be used in applying this standard.

This SAE Standard provides names of major components peculiar to rollers and compactors. Illustrations of components are not intended to be exactly descriptive of any particular machine. See Figures 1 to 3.)

This SAE Standard establishes terminology and the content of commercial literature specifications for self-propelled crawler and wheeled material handlers, pedestal mounted material handlers and their equipment as defined in 3.1. Illustrations used here are not intended to include all existing commercial machines or to be exactly descriptive of any particular machine. They have been provided to describe the principles to be used in applying this document. (Material handlers share many design characteristics with hydraulic excavators and log loaders; primarily 360 degree continuous rotation of the upperstructure relative to the undercarriage or mounting. They differ in their operating application. Material handlers are used for the handling of scrap material and normally utilize grapples or magnets. Hydraulic excavators are used for the excavation of earth, gravel and other loose material utilizing a bucket.

This standard identifies earthmoving machines which are intended for use on unimproved surfaces. The machines are used for moving earth and other materials on projects such as road building, dams, open pit excavation, trenching, and buildings. Excluded are machines intended for use on improved surfaces such as "in-plant" material handling, highways, water, air transport, and for agricultural purposes.

This recommended practice applies only to straight, angling, semi-U, and U-blade dozers for crawler and wheel tractors. It applies to angling blade dozers only in the straight (not angled) position.
