Specification Definitions--Hydraulic Backhoes J49_198004

The purpose of this standard is to establish a uniform method of providing dimensional operational specifications for hydraulic backhoes. This standard includes the definitions of specification most commonly used to describe nonfull-rotating hydraulic backhoes. Dimensional and operational specifications are to be determined without assembly or equipment changes such as buckets, dippersticks, etc. When specifications are affected by adjustable or extendable members, the position must be specified. Paragraphs 4.2.1-6.2 are further defined by Figs. 1-8. Figs 1-8 are not intended to be descriptive of any existing machine and are used only to clarify the meaning of the standard.
