Good performance Original Japan Caterpillar Cat 340DL large excavator 40Tons used excavator low price In stock with EPA/CE

A detailed description of the Caterpillar 340D hydraulic excavator, covering its positioning, technical parameters, core features and applicable scenarios:

1. Equipment positioning

Product line: Belongs to the Caterpillar D series, positioned as a medium-sized hydraulic excavator, focusing on general engineering and medium-intensity operations.

Target market: Suitable for scenes such as urban construction, road construction, and farmland water conservancy, taking into account flexibility and durability.

Differentiation positioning: Lighter and smaller than the 349D, suitable for projects with limited space or frequent transfers.

2. Core parameters

Operation weight: About 35-40 tons (varies depending on the configuration).

Engine: Equipped with a Cat® C9 ACERT™ diesel engine, with a power of approximately 224-246 kW (300-330 horsepower), meeting Tier 3/Stage IIIA emission standards.

Bucket capacity: Standard configuration is about 1.2-2.1 m³ (suitable for conventional operations such as earthwork and stone).

Maximum digging depth: about 6.5-8 meters (depending on the boom and bucket rod options).

Travel speed: about 3.1-5.5 km/h (crawler design, suitable for complex terrain).

3. Core technical features

Hydraulic system:

Cat intelligent hydraulic system (simplified version): adopts dual pump confluence technology to improve operating speed and fuel efficiency.

Supports power mode (P mode) and economic mode (E mode) switching to balance performance and fuel consumption.

Structural design:

High-strength box-type structure boom/bucket rod: strengthen key welding points and extend service life.

Wide crawler chassis: standard 600-800 mm crawler shoes, enhance ground stability and reduce pressure on soft ground.

Fuel management:

ACERT engine technology: optimize combustion efficiency and reduce fuel consumption under some working conditions.

Optional automatic idle function to reduce idling fuel waste.

4. Cab and operating experience

Human-machine interaction:

ROPS/FOPS certified cab: basic noise reduction and shockproof design, standard air conditioning and adjustable seats.

Mechanical instrument panel + LCD display: real-time display of key data such as fuel quantity, water temperature, hydraulic oil temperature, etc.

Maneuverability:

Mechanical hydraulic control lever, direct operation feedback (some models can choose electric control handle).

No intelligent auxiliary system (such as slope control), relying on operator experience.

5. Applicable scenarios

Urban construction: foundation pit excavation, pipeline laying, greening project.

Road construction: roadbed leveling, ditch excavation, stone loading.

Agriculture and water conservancy: farmland irrigation channel cleaning, dam reinforcement.

Small and medium-sized mines: cooperate with breaker for primary crushing of ore (need to strengthen accessories).

6. Comparison with 349D

Features 340D 349D

Operating weight 35-40 tons 44-48 tons

Engine power 300-330 hp 385 hp

Bucket capacity 1.2-2.1 m³ 1.9-3.1 m³

Applicable scenarios Medium-sized projects, space-constrained sites Medium-to-high-intensity projects, mining auxiliary operations

Flexibility Higher (lightweight, easy to transfer) Lower (suitable for heavy-duty operations in fixed sites)

Fuel consumption Lower (lower engine power) Higher

7. Advantages and limitations

Advantages:

High cost-effectiveness: purchase and operating costs are lower than those of larger tonnage models (such as 349D).

Durable and reliable: D series classic design, low failure rate, easy access to repair parts.

Flexible adaptation: can be configured with a variety of attachments (buckets, hydraulic hammers, grabs, etc.).

Limitations:

Outdated technology: lack of intelligent auxiliary systems (such as automatic leveling, remote monitoring).

Emission restrictions: Only meets Tier 3 standards, and may not be used in strict environmental protection areas.

8. Maintenance and care

Convenience design:

Centralized lubrication points and openable side doors facilitate daily inspection and maintenance.

The engine compartment has a clear layout and easy filter replacement.

Key component life:

Core components such as hydraulic pumps and swing motors have a long design life, with an average overhaul cycle of about 10,000-12,000 hours (depending on the working conditions).

9. Market positioning summary

The Caterpillar 340D is a medium-sized excavator with economical and practical as its core, suitable for users with limited budgets but requiring stable performance. Its balanced performance and low maintenance cost make it still competitive in the second-hand market, especially for the following situations:

The project is medium-sized and requires high equipment flexibility.

No advanced intelligent functions are required, relying on manual operation.

Regions with loose environmental protection policies (Tier 3 emissions are still acceptable).
