Equipment Overview
The CAT 329 is a 31.3-tonne excavator built for general construction and heavy earthmoving where reach and digging force matter. A mass excavation boom option offers significantly higher digging forces and larger buckets, with reaches over 8.3 m, making the machine well suited to ditch cleaning and high-volume material handling. The lower frame is reinforced for durability, and enlarged bucket linkage pins improve reliability under sustained heavy use.
Power comes from a Cat C7.1 ACERT engine producing 173 kW (232 hp), meeting EPA Tier 4 Interim and EU Stage IIIB emissions standards through Caterpillar’s aftertreatment regeneration system, which runs automatically without interrupting work. An electric swing priority valve, controlled by the machine’s Electronic Control Module, gives finer control during material loading than a conventional hydraulic valve, and a high-pressure hydraulic system delivers strong hydraulic horsepower for tough digging conditions.
