This article is the first in a series aimed at the study of hydraulic excavators: history of hydraulic excavators, parts, equipment, proper use of parameters to be taken into account in order to compare hydraulic excavators with one another. The history of the hydraulic excavator: they appeared first in Europe; in the initial stages there were hybrids using compressed air bottles to drive one of the units. There were very simple machines which were moved by towing. Front progression and "retro" machines were available. The self-propelling hydraulic excavator appeared around 1960, as well as a new item of equipment: the "bivalve hydraulic excavator". In ten years the total number of hydraulic excavators in the world was multiplied eleven-fold, two tendencies being evident up to 1969: the rapid increase in demand and an increase in power. In recent years the range of activity has greatly enlarged and the relative importance of the number of excavators on tracks has increased in proportion to those on tyres. (TRRL)
