Used Excavator SANY SY485H

SANY SY485H Crawler Excavator is a 49-ton-class large heavy-duty mining hydraulic excavator engineered to deliver high productivity, structural reliability, and low fuel consumption in continuous rock operations. It is widely deployed across open-pit mining, large-scale quarrying, heavy demolition, and massive earth-moving infrastructure developments.

Common Variations

SY485H: The core baseline configuration boasting an operating weight of approximately 49,500 kg. It typically matches a heavy-duty rock bucket ranging from 2.2 to 2.8 m³ and is optimized for mass quarrying and rock loading.
SY485H-S: A technology-updated variant configured with an advanced common-rail electronic engine system to comply with strict regional emission tiers, featuring refined hydraulic line configurations and digital management interfaces.
SY485HD: A custom structural adaptation utilizing modified front-end geometry, reinforced piping packages, and heavy counterweights designed to handle continuous impact attachments or hydraulic shear applications.

Core Advantages & Features

Customized Isuzu Power Unit: Driven by a high-torque Isuzu 6WG1X engine producing up to 300 kW (402 hp). The engine is finely calibrated with the main hydraulic pumps to achieve peak output at a lower, fuel-saving RPM range.
Dynamic Flow Matching (DOMCS): Employs SANY’s proprietary Dynamic Optimization Intelligent Control System, paired with an electro-hydraulic positive flow layout. It senses instantaneous workloads to smoothly channel oil flow, decreasing internal fluid friction losses.
Aggressive Breakout Force: Engineered for tough material fragmentation, generating a formidable 287 kN bucket digging force and a 245 kN arm breakout force to eliminate structural bog-down during high-wall extraction.
Mine-Grade Chassis Longevity: Formed with a heavily reinforced X-frame layout, heavy-duty track rollers, and robust double-grouser shoes. The undercarriage structure minimizes chassis flexing under heavy over-the-side lifting to secure a prolonged machine lifespan.
