Used Excavator SANY SY650H

SANY SY650H Crawler Excavator is a 65-ton-class super-heavy mining hydraulic excavator engineered to deliver maximum productivity, extreme structural durability, and high fuel efficiency under continuous, intense workloads. It is widely deployed in large-scale open-pit mines, heavy-duty quarrying, massive earth-moving operations, and infrastructure projects.

Common Variations

SY650H: The baseline heavy-duty model commonly equipped with a high-power Isuzu 6WG1 engine (rated up to 377 kW) and a 3.5 to 4.2 m³ heavy rock bucket optimized for dense material blasting and loading.
SY650HB: Shares the same core 63,200 kg operating weight but features customized exhaust aftertreatment and power calibration (such as a 345 kW rating) to comply with stringent regional environmental regulations.
SY650HD: A specialized configuration designed for specific engineering needs, featuring reinforced front-end structures and extended arm options for deep extraction or vibratory hammer operations.

Core Advantages & Features

Dynamic Integration & Control: Powered by SANY’s independently developed DOMCS (Dynamic Optimization Intelligent Control System). It integrates a customized large-displacement main pump to ensure the hydraulic output seamlessly matches the engine’s optimal fuel efficiency range.
Extreme Structural Longevity: Built with heavily reinforced X-chassis and stress-relieved boom structures. The core components are engineered for a design lifetime of up to 25,000 hours, reducing structural stress by 15% compared to standard heavy models.
High Output Mining Persistency: Delivers an impressive 345 kN bucket digging force. It utilizes an advanced electro-hydraulic positive flow system that automatically raises output pressure as load demands increase.
Intelligent Car-Class Cabin: Equipped with a spacious, pressurized operator cabin featuring premium vibration-damping suspension seats, multi-stage noise insulation, intelligent climate control, and a comprehensive digital vehicle monitoring system.
