Product Details

While engineered as SANY’s flagship heavy miner, this 2020 SY550H worked exclusively on soft coal stockpile stripping and loose coal rehandling at a coastal energy transshipment hub. It has NEVER been fitted with a hydraulic rock breaker or worked in blast-zone granite quarries. Operating on flat surfaces with low-density materials, its reinforced H-type boom, heavy mine-spec arm, and rigid X-frame maintain absolute factory structural integrity.

FAQ

The “H” stands for Heavy-Duty/Mining Series. Compared to standard large models, the SY550H features a heavily reinforced boom and arm with thick high-tensile steel plates, an independent oil radiator system, and a mine-grade undercarriage to withstand demanding high-tonnage production cycles.

Due to its massive dimensions and weight, it is shipped via Bulk Vessel, Ro-Ro, or a Flat Rack Container rather than standard containers to ensure structural safety. Our logistics team handles all heavy maritime securements with high-tensile steel chains.

Yes. We provide an uncut Hydraulic Operation & Stunt Test video: our operators force the heavy-duty bucket down to lift the entire 53.5-ton chassis completely off the ground, proving the main pumps and control valves hold tight with zero pressure bleed-down or cylinder drift.

Yes, 100%. The stamped Chassis VIN on the factory plaque and the Engine Serial Number perfectly match the Contract, Commercial Invoice, and Bill of Lading. We welcome independent third-party port audits (SGS/TÜV) before loading.

This unit receives our full Heavy Fleet Maintenance Suite: we completely flush and replace the engine oil, hydraulic oil, and heavy final drive lubricants. We also install brand-new genuine filters, inspect all electrical circuitry, and thoroughly grease all heavy-load linkage pins.

Yes. Our certified technicians connect SANY diagnostics software directly to the Isuzu ECM, verifying that all power modes, smart throttles, and digital display parameters are fully functional and all historical fault codes are completely cleared.
