crawler excavator

The SANY SY365H is a 36–37 metric ton class crawler excavator designed for heavy-duty earthmoving, quarrying, and mining applications. The operating weight ranges from 36,000 kg to 36,800 kg depending on configuration, with a standard bucket capacity of 1.6–1.9 m³ (rock bucket) and an optional maximum bucket capacity of 2.32 m³ for lighter materials. It is powered by an ISUZU 6HK1 six-cylinder diesel engine with displacement of 7.79 L, delivering rated power of 210–212 kW at 1,900–2,000 rpm and maximum torque of 1,080 Nm at 1,500 rpm. The machine achieves travel speeds of 5.5 km/h (high) and 3.5 km/h (low), with a swing speed of 9.2–9.5 rpm. Maximum digging depth reaches 7,050 mm, maximum digging height is 9,890 mm, and maximum digging radius extends to 10,780 mm. The undercarriage features 600 mm standard track shoes with 49 track links per side. Fuel tank capacity is 620 L and hydraulic oil tank holds 380 L.

The SY365H demonstrates excellent fuel efficiency through SANY‘s patented “positive flow” hydraulic system and self-developed DMOS (engine-pump-valve integrated dynamic optimization intelligent control system). Under typical working conditions, fuel consumption ranges from 18–22 liters per hour, with actual user feedback from mining operations confirming real-world consumption below 29 L/h. According to official data, the SY365H’s average working efficiency is increased by 7.5% and average fuel consumption lowered by 10% compared to competitor models. The upgraded SY365H-S Stage IV model (without urea addition) maintains comparable fuel consumption to Stage III models while improving main-gear efficiency by 3–5% and increasing bucket capacity from 1.6 m³ to 1.9 m³, raising overall operational efficiency by 10%. The machine is often summarized in the industry as delivering “40-ton class efficiency with 30-ton class fuel consumption”. With a 620 L fuel tank, continuous operation of 28–34 hours per refueling is achievable. In a 10-year case study of an Australian mining operation, the SY365H’s average fuel consumption remained within 10% of original specifications even after 20,000+ engine hours.

The SY365H features an advanced load-sensing positive flow hydraulic system centered around an upgraded 180 cc main pump (increased from 160 cc in earlier models) and large-diameter main valve. Dual hydraulic pumps deliver a combined flow rate of 2 × 400 L/min, enabling simultaneous operation of multiple hydraulic circuits for efficient multi-function performance. Bucket digging force reaches 235 kN (with power boost) and arm digging force is 180–210 kN depending on configuration. The Stage IV upgrade model (SY365H-S) features a further optimized hinge point design that broadens the effective digging force scope, increasing arm digging force by 15% to 210 kN. The travel motor driving force is rated at 320 kN with the Nabtesco large-torque travel mechanism. The 380 L hydraulic oil capacity ensures consistent system performance even in high-demand applications. For used machine buyers, verifying hydraulic system cleanliness and absence of abnormal noise during multi-function operation is essential—well-maintained SY365H units consistently demonstrate smooth, responsive hydraulic performance. Common hydraulic issues include main pump pressure sensor failures (fault code H209) and seal leaks, both of which are repairable with standard diagnostic tools.

Used SANY SY365H pricing varies significantly based on age, operating hours, condition, and market region. For newer units (within 1–2 years old, under 500–600 hours, excellent condition), prices typically range from US $42,000 to $46,000 FOB China. A 2023 model with approximately 335–728 working hours is commonly priced around US $38,000–$40,000. A 2021 model with ultra-low 500 hours is valued at approximately US $105,900 in certain markets, reflecting its near-new condition. For reference, a 2014 SY365H with 10,231 working hours is priced around US $21,800 in the domestic Chinese market, demonstrating significant depreciation for high-hour units. Multiple factors influence final pricing: machines with documented service history, reinforced undercarriage with 70%+ remaining life, clean hydraulic systems, and no oil leakage command premium valuations. Verified 2024 models in “like-new” condition (under 600 hours) typically list at US $42,000–$44,000, while high-hour units (8,000–10,000+ hours) fall into the US $20,000–$25,000 range.

The SY365H is engineered for long-term durability, with structural components designed to exceed 15,000 operating hours in mining and quarry conditions, and a maximum design lifetime reaching 25,000 hours for later upgraded models—30% longer than previous generations. Key durability features include reinforced boom and arm structures with cross-section coefficient increased by over 10%, optimized welding processes (single-sided welding with double-sided formation), and stress-relieving techniques that lower average stress at high-load points by more than 10%. The chassis incorporates extended undercarriage design with a 330 mm increased X-frame cross-section (5%+ improvement), plus reinforced four-wheel system with doubled lifespan and multi-stage protective plate structure increasing service life by 100%. A real-world case study of a SY365H operating in an Australian mine for 10 years recorded over 20,000 engine hours with no major overhauls, only routine maintenance (oil changes, filter replacements). The machine retained 90% of its original digging force after a decade, with total cost of ownership estimated at US $0.25 per operating hour—well below industry averages. For used buyers, a well-maintained SY365H with documented service history and routine 500-hour service intervals remains a reliable workhorse well beyond 12,000–15,000 hours.
