Used Excavator CAT 340D2L

Caterpillar CAT 340D2 L Crawler Excavator is a 40-ton-class heavy-duty hydraulic excavator engineered to deliver exceptional productivity, immense lifting capacity, and lower operating costs. It is widely deployed in large-scale quarrying, open-pit mining, heavy earthmoving, and rigorous infrastructure projects where high breakout force is critical.

Common Variations & Twin Models

340D2 L: The baseline heavy-duty setup with a long undercarriage, featuring an operating weight of approximately 38,900 kg to 40,270 kg. It is commonly matched with a 1.9 m³ heavy-duty bucket for high-volume loading.
340D2 L Mass Excavation: Configured with a shorter, stubbier mass-excavation boom and arm assembly, driving the operating weight up to 41,500 kg. This variation maximizes breakout forces and accommodates even larger buckets for rapid truck loading.
340D L Series 2 / Global Counterparts: Shares the same foundational structural backbone but features minor regional differences in factory electronic calibrations and emission kits to comply with localized Stage II / Tier 2 equivalent standards.

Core Advantages & Features

ACERT™ Power Optimization: Powered by a heavy-duty Cat C9 ACERT™ engine delivering a net flywheel power of 200 kW to 208 kW (270–283 hp). It utilizes electronic isochronous speed control to reduce RPMs under light loads, slashing fuel consumption by up to 7% over predecessor platforms.
High Wide Undercarriage Stability: Built with a wider track gauge and heavier carbody framing that offers 13% greater stability compared to the 33-ton class 336D2 L platform. This design allows the excavator to safely handle massive attachments and perform heavy over-the-side lifting.
Positive Flow Hydraulic Delivery: Features an efficient twin-pump layout outputting up to 530 to 587 L/min of flow at a high system operating pressure of 35,000 kPa. Electric pressure sensors precisely detect load demand to eliminate hydraulic fluid waste and speed up cycle transitions.
Pressurized Dust-Free Cab: Assembled with a spacious, rubber-mounted workstation that utilizes a structural sealing and pressurization system to keep working environments clean and silent. It includes pilot-operated joysticks, adjustable suspension seating, and framing-free glass layouts for panoramic job site tracking.
