1. Product Parameters

2. Detailed Description and Introduction

Overview

The Used Komatsu PC400 Excavator is a heavy-duty hydraulic excavator engineered for demanding earthmoving tasks. This 2017 model, with approximately 2,500 operating hours, combines Komatsu's proven mechanical architecture with a robust hydraulic system to deliver consistent performance across construction, mining and large infrastructure projects. Its 40 t operating weight and powerful Komatsu diesel engine make it a dependable choice for operators seeking both traction and digging power.

Powertrain and Performance

The excavator is powered by a Komatsu SAA6D125E-5 engine (also referenced as S6D125 in some specifications), a 11.05-litre diesel unit rated at 199 kW. The engine delivers strong low-end torque at around 2,000 rpm, enabling reliable digging force and steady swing performance under load. The factory hydraulic system and pump controls are tuned for stable, responsive operation, allowing operators to cycle attachments efficiently while maintaining fuel economy consistent with Komatsu design principles.

Structural Durability and Undercarriage

The PC400’s frame and boom are constructed to withstand heavy cycle loads. The tested SL undercarriage and 610 mm track shoes provide a balanced ground footprint for stability on uneven terrain. Structural components and pivot points are reinforced for longevity; routine inspection and well-documented maintenance history are recommended to maximize service life and ensure predictable resale value.

Hydraulics, Controls and Operator Comfort

Komatsu’s hydraulic control layout ensures smooth, proportional response for precise grading and trenching operations. The cab ergonomics on the PC400 prioritize operator visibility and control accessibility. Standard features typically include climate controls, an adjustable seat, and straightforward instrument cluster readouts—components that reduce operator fatigue and increase productivity on long shifts.

Attachment Compatibility

This unit supports a range of buckets and hydraulic attachments; the bucket capacity is listed as 2.24 m³ in the detailed parameter set, while a 2.8 m³ bucket is also cited in configuration notes. Selection of bucket size and auxiliary gear should be matched to the intended application to preserve cycle times and maintain rated lifting and digging capacities.

Primary Applications

• Large-scale earthworks and site preparation

• Quarry and surface mining operations

• Heavy foundation excavations and trenching

• Road construction and material handling with appropriate attachments

Maintenance, Inspection and Service History

A used Komatsu excavator’s value depends heavily on its maintenance record. For this 2017 unit with 2,500 hours, a thorough service history—documenting oil and filter changes, hydraulic inspections, track tension adjustments and any structural repairs—is a key purchasing consideration. Prioritize units with verified servicing by authorized technicians or reputable workshops to reduce downtime risk and ensure compliance with safety standards.

Advantages and Buyer Benefits

1. Proven reliability from a global manufacturer with accessible parts networks.

2. Balanced performance for heavy digging while offering reasonable fuel efficiency.

3. Flexible configuration options to suit mining, construction, and civil projects.

4. High resale potential when maintained per manufacturer recommendations.

Who Should Consider This Machine

Contractors, quarry operators and civil engineering firms that require dependable mid-to-large class excavators will find the Used Komatsu PC400 Excavator suitable. It is especially relevant for operations that need a balance of digging power, stability and serviceability without the lead time and cost of new equipment procurement.

Ordering, Delivery and Support

The unit originates from Japan and is available for delivery within 15–20 days. Supply capacity is indicated at 10,000 units/month for the supplier network, which supports fleet acquisition programs. Prospective buyers should confirm final inspection reports, shipping terms and any required export documentation prior to placing orders.

Final Notes

The Used Komatsu PC400 Excavator represents a practical choice for heavy-duty applications where durability and reliable performance are essential. When evaluating this unit, align bucket and attachment choices to the task, verify the maintenance history, and consider on-site inspection or third-party evaluation to validate condition and operating capability.
