Equipment Type

 Crawler Excavators

Crawler Excavators are utilitarian machines that can dig trenches, load trucks, lift pipe, and handle attachments, such as hydraulic breakers, shears, and grapples. These machines range in size from the "mini" that fits through a back-yard gate, to those in mining applications and have operating weights of a quarter million pounds or more.


The DX420LC-5, DX490LC-5 and DX530LC-5 Tier 4-Final excavators replace the T4-I Dash 3 versions.

Following the release of four intelligent Machine Control (iMC) crawler dozers, Komatsu has now introduced its first intelligent Machine Control excavator, the PC210LCi-10.

Link-Belt Excavators X4 series have Isuzu Tier 4-Final engines that provide up to 12 percent improved fuel efficiency, using SCR technology.

Tier 4-Final upgrades to the Cat 390F and 374F excavators include the Cat ACERT C15 with 472 horsepower in the 374F and the C18 with 524 horsepower in the 390F.

The 323F L excavator has a 161-horsepower C7.1 engine, which gives it 9 percent better fuel efficiency than the E Series predecessor.


More than 400 people attended AEMP’s symposium on telematics last month, a number far exceeding previous educational events.
