Basic parameters and positioning

Model positioning

The medium hydraulic excavator belongs to the Caterpillar 300D series and is suitable for high-intensity work scenarios such as mines, quarries and large earthworks.

Operating weight: approximately 36-38 tons (depending on configuration).

Dynamic system

Engine: Equipped with Cat C9 ACERT turbocharged diesel engine, compliant with Tier 3/ National 3 emission standards.

Power: Net power of approximately 202 kW (271 HP), strong torque, suitable for heavy duty operations.

Fuel tank capacity: approximately 500 liters, supporting long continuous operation.

Job performance

Bucket capacity: Standard 1.9-2.2m ³ (optional rock bucket, reinforced bucket, etc.).

Mining power:

Bucket digging force: about 230 kN

Bucket rod digging force: about 180 kN

Maximum digging depth: approx. 7.2 m (standard arm configuration).

Core technology and upgrade highlights

Hydraulic system optimization

Load Sensitive Hydraulic System (CLSS) : Dynamically adjusts the flow according to the load, reducing energy consumption and improving movement coordination.

Dual pump confluence technology: the composite action (such as walking + turning) is more smooth, and the efficiency is increased by about 15%.

Structural strengthening design

Type X reinforced frame: more torsional resistance to rough terrain and heavy impact.

Reinforced bucket rod and boom: the key parts are made of high-strength steel, and the life is extended by 20%.

Intelligent control

Cat electronic monitoring system: real-time display of fuel consumption, hydraulic temperature, fault code and other data.

Automatic idle function: automatically reduce engine speed when no operation, saving fuel.

Application scenarios and advantages

Mines and quarries

High excavation force and durable construction are suitable for heavy duty tasks such as crushing and loading.

Optional hydraulic hammer (such as HB series) for rock breaking.

Large earthworks

Large capacity buckets and fast cycle times improve earthmoving efficiency.

Adaptability to harsh conditions

Three-stage fuel filtration system + dust-proof radiator to ensure the stability of the engine in a dust environment.

Maintenance and cost control

Easy maintenance

Centralized lubrication points: Key hinged parts are easy to maintain.

Side open hood: adequate engine and hydraulic system maintenance space.

Maintenance cost

Filter life: the replacement cycle of hydraulic oil filter is about 1000 hours, and the fuel filter is about 500 hours.

Cat S∙O∙S Service: Reduce unplanned downtime with predictive maintenance through oil analysis.
