Caterpillar was late breaking into the hydraulic excavator market, but with homegrown competitors already in the market, like Koehring and Link-Belt, for a number of years, and the threat of foreign machines from Hitachi, Kato and Komatsu, Caterpillar was not going take this lying down.
Throughout 1968, through 1970, Caterpillar tested a number of power-plants and machine configurations at their Arizona proving grounds. Finally putting into production the 51U, soon to be known as model 225 in 1972
Caterpillar’s first hydraulic excavator had finally come to market.
Today’s equivalent to the vintage 225 is the 320, which is again on the cutting edge of CAT® machines and spearheading the Next Generation in Excavators.
