Caterpillar 320D2L Crawler Excavator Detailed Introduction

The Caterpillar 320D2L is a 22-ton class heavy-duty crawler excavator developed by Caterpillar Inc. as an upgraded iteration of the classic 320D series, tailored for high reliability, fuel efficiency and adaptability to harsh working conditions across construction, mining, infrastructure and municipal projects. The suffix "L" stands for long undercarriage, which delivers superior stability and low ground pressure for soft terrain operations.

1. Engine & Fuel Efficiency

The 320D2L is equipped with a Cat C7.1 ACERT inline 6-cylinder turbocharged air-to-air aftercooled diesel engine, compliant with Tier 3/Stage IIIA emission standards:

Net power output: 108 kW (145 hp) at 2000 rpm
Optimized high-pressure common rail fuel injection system, paired with dual-stage fuel filtration and water separator, adapts to low-quality diesel in emerging markets and reduces injector failure risk
Auto idle speed reduction and on-demand cooling fan cut fuel consumption by 6-8% compared to the older 320D model, with average fuel consumption of 12-18 L/h under typical working conditions
Optional cold start kit supports normal start-up at temperatures as low as -32℃, and high-altitude calibration kit ensures stable performance above 3000m elevation
Fuel tank capacity: 410 L, supporting long-hour continuous operation

2. Hydraulic System

It adopts Caterpillar's proprietary load-sensing hydraulic system with pressure compensation, to deliver precise control and smooth compound movements:

Main pump maximum flow: 2 × 202 L/min, system working pressure: 35 MPa
4 selectable working modes: Power mode (for heavy-duty digging/demolition), Economy mode (for light-duty earthwork to save fuel), Lifting mode (for heavy hoisting with stable pressure), Fine mode (for precision operations like trenching/grading)
Independent swing and travel circuits ensure no speed drop when performing simultaneous actions (digging + swinging + traveling)
Hydraulic oil capacity: 240 L, with high-efficiency filtration system to extend oil service life

3. Undercarriage (Long Configuration)

The extended tracked undercarriage is designed for maximum stability and durability:

Standard track gauge: 2200 mm, track length on ground: 3650 mm
Ground pressure with standard 600mm track shoes: 33 kPa, far lower than standard 320D2, suitable for muddy, swampy or soft soil construction sites
Sealed and lubricated track links, support rollers and idlers reduce wear, with service life of over 8000 hours under normal working conditions
Heavy-duty travel reducer delivers maximum drawbar pull of 214 kN, strong climbing ability (max gradeability: 35°)
Optional 700mm/800mm widened track shoes, or rubber track pads for road protection operations

4. Work Equipment

All work tools are made of high-strength tensile steel with stress relief treatment, adapting to heavy impact loads:

Standard boom length: 5.7 m, optional stick lengths: 2.5 m (for rock mining), 2.9 m (general purpose), 3.2 m (for deep digging)
Standard bucket capacity: 1.0-1.5 m³, optional bucket types: heavy-duty rock bucket, earthwork bucket, ditching bucket, with wear-resistant Cat bucket teeth that have 30% longer service life than generic products
Key performance parameters (with 5.7m boom + 2.9m stick):
- Max digging depth: 6720 mm
- Max digging height: 9450 mm
- Max dumping height: 6510 mm
- Bucket digging force: 155 kN
- Stick digging force: 114 kN
- Max swing speed: 11.5 rpm

5. Operator Cabin

The ROPS/FOPS certified safety cabin is designed for long-hour operation comfort:

Sound insulation design reduces interior noise to 72 dB(A), far lower than industry average
Fully adjustable air-suspension seat with lumbar support, adjustable armrests to fit operators of different heights
Low-effort pilot control joysticks reduce operating fatigue
High-performance air conditioning system with 10 adjustable air outlets, optional heating function for cold regions
7-inch LCD monitor displays real-time operating data, maintenance reminders and fault codes, with multi-language support
Standard USB charging port, storage compartments, cup holder and radio for enhanced convenience
Optional rearview camera system to eliminate blind spots

6. Maintainability

All service points are accessible from ground level to reduce maintenance time:

Extended maintenance intervals: Engine oil & filter change: 500 operating hours; Hydraulic oil change: 5000 operating hours; Air filter replacement: 2000 operating hours; Return oil filter replacement: 1000 operating hours
Built-in Caterpillar Product Link remote telematics system, supporting real-time tracking of equipment location, working hours, fuel consumption and fault alerts for fleet management
Centralized grease points for easy regular lubrication

7. Typical Applications

Municipal engineering: road construction, pipe laying, trench digging
Infrastructure: bridge construction, tunnel supporting, site clearing
Mining & quarrying: ore loading, rock excavation, stripping work
Demolition: building tearing down, construction waste handling
Forestry & agriculture: land clearing, water conservancy project construction
Material handling: bulk cargo loading, heavy hoisting

8. Optional Attachments

Quick coupler, hydraulic breaker, hydraulic shear, grapple (wood/stone/waste), plate compactor, auger, ripper, etc.

Caterpillar's global dealer network provides 24/7 after-sales support, genuine parts supply and professional maintenance services, with standard 1-year/2000-hour warranty for new machines.
