Product Overview

As a flagship model of Caterpillar's classic D-Series, the 329D is a 29-ton heavy-duty medium crawler excavator widely recognized in the global construction industry for its outstanding durability and high residual value. It is equipped with a genuine CAT C7 ACERT turbocharged diesel engine and a factory-tuned high-flow load-sensing hydraulic system, delivering robust digging force, stable power output and excellent long-term reliability. This model has been field-proven worldwide as a workhorse for heavy earthmoving, quarry loading and large-scale infrastructure projects.

Every used 329D excavator in our inventory has completed a strict 90-point full-machine technical inspection and professional reconditioning. We guarantee no major structural accident history, 100% original factory core components, and traceable scheduled maintenance records. With well-preserved heavy-duty performance and a much lower acquisition cost than brand-new equipment, it is a highly cost-effective core asset for overseas medium-to-large contractors and professional rental fleet operators.
