20.4 Ton CAT 320 GC Excavator — Cat C4.4 / Tier 3 Equivalent
20.4-ton medium-class hydraulic excavator. Cat C4.4 engine, 107 kW net power at 2,000 rpm (ISO 9249), 4.4 L displacement, meets Brazil MAR-1 and equivalent to U.S. EPA Tier 3 / EU Stage IIIA. 1.0 m3 general duty bucket, 129 kN bucket digging force, 99 kN stick digging force. Maximum digging depth 6,630 mm, maximum reach at ground level 9,770 mm. 345 L fuel tank, medium undercarriage with 2,380 mm track gauge, 3,700 kg counterweight.
The CAT 320 GC is a new 20-tonne crawler excavator for general earthmoving, trenching and truck loading — work where reach and cycle time matter more than maximum breakout force. This unit is built on the medium undercarriage with a reach boom, the R2.9 stick and a general duty bucket, a configuration suited to road, utility and site-preparation contractors.
Emissions meet Brazil MAR-1 and are equivalent to U.S. EPA Tier 3 and EU Stage IIIA. The engine runs without DPF or SCR aftertreatment, so there is no DEF to source and less exposure to local diesel quality — a practical fit for fleets in Brazil, the wider Latin American market, Africa and the Middle East.
Machines are brand-new and ship from our yard with the complete export document pack. FOB China and CIF prices are quoted on request.
Five points that decide whether the 320 GC fits your fleet: engine output, emission level and fuel needs, digging envelope, undercarriage size for transport, and daily service access.
Cat C4.4 engine - 107 kW net power at 2,000 rpm (145 hp metric) per ISO 9249, 108 kW per ISO 14396, 4.4 L displacement, single turbo diesel. Biodiesel capability up to B20.
Meets Brazil MAR-1 and is equivalent to U.S. EPA Tier 3 and EU Stage IIIA. Without DPF or SCR aftertreatment the machine needs no DEF supply and is less sensitive to local diesel quality than a Tier 4 Final unit — a practical fit for Brazil, the wider Latin American market, Africa and the Middle East.
