Product Specification

Pre-Owned KOMATSU PC750SE-7 Mining Excavator 75 Ton Heavy Duty Hydraulic Crawler Digger Equipment Inspected Export

Product Overview

The used KOMATSU PC750SE-7 excavator is a 75 ton heavy-duty hydraulic crawler excavator designed for large-scale mining operations, quarry material loading, heavy construction earthmoving, infrastructure development projects, mass excavation applications, and industrial material handling requiring substantial breakout force, deep digging capability, and high production rates in demanding work environments. KOMATSU is a globally recognized heavy equipment manufacturer with an established track record in producing durable mining and construction machinery with comprehensive parts and service support networks operating in mining regions worldwide. This used unit has been carefully inspected with complete maintenance records documenting its operating history, providing full transparency on previous mining or construction application type, scheduled service intervals, and any major component rebuilds or replacements performed during its operational lifetime. The machine retains original KOMATSU factory paint with no structural welding repairs or frame damage, confirming authentic condition and structural integrity for continued heavy-duty production work.

Key Features

The KOMATSU PC750SE-7 is powered by the KOMATSU SAA6D140E-5, 420 kW (563 HP) at 1,800 rpm diesel engine delivering substantial power output for continuous heavy-duty excavating and truck loading applications in mining and quarry operations. The operating weight of 74,800 kg provides excellent stability during high-production digging and loading operations with substantial breakout forces for tough digging conditions. The bucket capacity of 4.0 m³ enables efficient material handling with fewer loading passes per truck, improving overall production cycle times and reducing operating costs. The maximum digging depth of 8,170 mm and reach of 13,400 mm at ground level provides excellent working envelope versatility for bench loading, trench excavation, and material handling across the work face. The heavy-duty reinforced undercarriage features sealed and lubricated track chain with 700 mm triple grouser track shoes and 76 kPa ground pressure for reliable operation across varied ground conditions. The spacious operator cabin features ROPS and FOPS certified structure, climate control air conditioning, adjustable suspension seat, and excellent visibility for safe and productive multi-shift operation. The advanced hydraulic system provides smooth simultaneous multi-function operation with boom priority and arm regeneration circuits for fast cycle times and reduced fuel consumption.

Technical Specifications

Condition and Inspection

Prior to shipment, each KOMATSU PC750SE-7 excavator undergoes structured multi-point pre-delivery inspection conducted by certified heavy equipment technicians with mining equipment specialization. The engine receives cylinder compression testing across all cylinders with results compared against OEM specification tolerances, turbocharger boost pressure verification under load, cooling system pressure retention testing, fuel injection system calibration verification, and spectrographic oil analysis for wear metal detection with trend comparison. The complete hydraulic system undergoes main pump flow rate measurement at rated engine speed against OEM specification, all circuit relief valve pressure setting verification, cylinder drift measurement across boom, arm, and bucket cylinders over timed observation periods, swing motor performance testing, and ISO 4406 oil cleanliness certification. The undercarriage system receives detailed measurement of track chain link wear percentage, sprocket tooth profile assessment, idler and track roller tread wear measurement, and track tension adjustment verification. A complete operational test sequence is executed including simultaneous multi-function operation of all hydraulic circuits, 360-degree swing cycle time measurement, travel speed verification, and all safety and monitoring system checks. All inspection results are documented with photographic evidence in a comprehensive pre-delivery inspection report.

Shipping and Delivery

We offer competitive ocean freight rates to destinations worldwide including Southeast Asia, Middle East, Africa, South America, Europe, and Oceania.
