Powertrain & Structural Overview

At the heart of this powerhouse lies a robust, high-displacement diesel engine, specifically tuned for heavy-duty cycles. The powertrain utilizes a selective catalytic reduction (SCR) system to meet stringent emission standards without compromising the net flywheel power, delivering up to 359 HP . The hydraulic system features a large displacement, closed-center load-sensing design. This setup provides optimal flow to the implements at lower engine RPMs, enhancing controllability for fine grading while delivering maximum breakout force for heavy rock excavation . The main control valve incorporates advanced flow sharing technology, ensuring smooth, simultaneous operation of boom, arm, and bucket movements. Structurally, the machine is built for longevity; the upper frame features special mounts for the ROPS cab, while the lower frame is reinforced with high-tensile-strength steel in the track shoes, links, rollers, and idlers . Grease-lubricated track links prevent debris ingress, significantly reducing wear and lowering owning and operating costs.

Technical Specifications

Below is the primary data for the Large Excavator Machine. These figures represent standard configuration; variations may occur with optional equipment.

Heavy-Duty Application Scenarios

Mass Earthmoving & Infrastructure

Ideal for large-scale site preparation, road construction, and canal digging. The machine's high drawbar pull and large bucket capacity allow for rapid loading of dump trucks, significantly accelerating project timelines on civil engineering works. Its advanced 2D/3D grade control compatibility ensures precision for complex slope and plane creations .

Quarrying & Aggregates

In the harsh conditions of rock quarries and gravel pits, durability is key. The heavy-duty (HD) reach and mass excavation (ME) boom options provide the necessary digging forces for fragmented rock . The robust undercarriage and reinforced swing frame easily handle the high torsional stresses encountered when loading from high benches, reducing downtime and maintenance costs.

Mining Support & Demolition

This excavator excels as a support machine in open-pit mining, handling overburden removal and site maintenance. With specialized work tools and quick couplers, it transforms into a powerful demolition machine for high-reach dismantling, showcasing its versatility beyond standard excavation tasks .

Equipment Q&A

Q1: What is the estimated shipping lead time for this Large Excavator Machine to a major port?
