VOLVO EC300D Crawler Excavator Detailed Introduction

The VOLVO 300D officially named Volvo EC300D Crawler Excavator, is a core mid-sized heavy-duty excavator in Volvo Construction Equipment’s D-series product portfolio. It is engineered for high efficiency, reliability, low operating cost and operator comfort, and is widely used in infrastructure construction, quarrying, mining, road building, municipal works and forestry operations around the world.

1. Powertrain & Working Performance

Core Power System

The EC300D is equipped with a self-developed Volvo D8H 4-stroke, 6-cylinder, turbocharged intercooled diesel engine, with optional emission standards for different regional markets:

EU Stage V / U.S. Tier 4 Final version (for high-emission-standard regions): Adopts selective catalytic reduction (SCR) and diesel particulate filter (DPF) technology, no need for frequent aftertreatment maintenance.
Tier 3 version (for emerging markets): Simplified aftertreatment system, adapts to low-quality fuel in remote areas.
Key power parameters: Net power of 194 kW (260 hp) at 1800 rpm, maximum torque of 1160 N·m at 1300 rpm, strong low-speed torque output, reduces frequent speed changes and fuel consumption.

Hydraulic System

It is fitted with Volvo’s advanced load-sensing, flow-sharing hydraulic system:

Precisely matches oil flow to operating demand, ensures smooth compound actions (e.g. simultaneous boom lifting, arm retracting and slewing) without lag, improves operating efficiency by 7% compared with the previous C-series model.
Equipped with 5 optional working modes: Idle, ECO, Standard, Power, Heavy Power, users can switch modes according to working conditions. The ECO mode can reduce fuel consumption by up to 10% without sacrificing productivity.
Optional hydraulic auxiliary lines, supports quick connection of various attachments.

Performance Indicators

Maximum bucket breakout force: 228 kN
Maximum traction force: 284 kN
Maximum travel speed: 5.5 km/h
Gradeability: 35° (70% slope)

2. Operator Comfort & Safety

Cab Design

The EC300D cab meets ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) international safety standards:

Ultra-low interior noise level of only 71 dB(A), vibration is reduced by 15% compared with similar products through multi-point suspension cab mounting.
Equipped with 12-way adjustable air-suspension high-back seat with optional heating function, ergonomic servo control joysticks with low operating force, reduces fatigue during long-time operation.
Narrow-pillar design with large-area tempered glass provides 360° unobstructed vision, standard rear view camera and 8 high-brightness LED working lights ensure safe operation at night or in low-light environments.

Safety Configuration

Standard anti-slip steps and guardrails, all high-voltage and high-pressure systems are equipped with overpressure protection and warning devices.
Automatic idle and auto-shutdown functions: reduces unnecessary fuel consumption and engine wear when the machine is not in operation.

3. Durability & Maintenance Convenience

Durability Design

The boom, arm, X-type undercarriage and main frame are made of high-strength wear-resistant steel, and have passed 10,000+ hours of extreme working condition tests in quarries and cold/hot regions.
Sealed and lubricated track chain, support rollers and idlers have a service life of more than 6000 hours under normal working conditions.
High-precision filtration system, hydraulic oil replacement cycle reaches 5000 hours, engine oil and filter replacement cycle is 1000 hours, greatly reduces maintenance costs.

Maintenance & After-sales Support

All daily maintenance points are accessible from the ground, no need to climb on the top of the machine, centralized greasing points reduce daily maintenance time.
Standard Volvo CareTrack remote telematics system: supports real-time monitoring of machine location, fuel consumption, working hours and fault warning, remote lock function, facilitates fleet management, reduces unscheduled downtime by more than 20%.
Volvo’s global 24/7 after-sales network ensures fast supply of original spare parts and professional technical support.

4. Main Technical Specifications
