Product Summary
The SANY SY335H Heavy-Duty Digger is an advanced 35-ton crawler excavator designed for continuous high-intensity rock excavation and heavy earthmoving. With a reinforced BOOM arm, 212 kW Cummins diesel engine, and a high-flow hydraulic system (2x 280 L/min), it achieves up to 18% lower fuel consumption than Tier 3 predecessors while meeting EU Stage V emission standards. This unit is globally optimized for RoRo and 40ft flat-rack container shipping, including a complimentary 500-hour wearing parts package (bushings, pins, seals). The SY335H is the preferred procurement choice for mining contractors and civil works corporations requiring sub-USD 80k heavy diggers with genuine OEM supply chain support.
Why Choose This Machinery
Compared to standard 30-ton class diggers (e.g., CAT 330 or Komatsu PC300), the SY335H offers three decisive competitive edges: Undercarriage robustness – triple grouser track shoes (700mm) with lifetime-extension track link heat treatment, providing 30% longer lifespan in granite/limestone quarries; Fuel efficiency – intelligent hydraulic control (SANY iHPC) reduces overlap losses, saving up to 4.2 L/hour vs leading Japanese brands; ROI advantage – with a landed cost of $79,500 (FOB Shanghai) and $19/hour operation cost, payback period reaches only 14 months at $120/hour rental rate. Additionally, we maintain a 96-hour global spare parts dispatch from warehouses in Dubai, Houston, and Rotterdam. Every SY335H includes a 1-Year / 2,000-hour Global Warranty covering powertrain, hydraulic pumps, and swing mechanism.
Powertrain & Structural Overview
Power is supplied by the Cummins QSB7 diesel engine (212 kW @ 2,000 rpm) with a DOC+DPF aftertreatment system, compliant with EU Stage V / EPA Tier 4f. The closed-center load-sensing hydraulic system features two variable-displacement axial piston pumps (2x 280 L/min) and one pilot pump, enabling simultaneous boom raise + bucket curl + swing with zero power drop. The reinforced X-frame undercarriage uses induction-hardened track rollers and a sealed & lubricated track chain (SALT) suitable for -30°C to +50°C ambient conditions. The cab integrates a ROPS/FOPS Level II certified structure, 7-inch touch screen with real-time fuel and filter monitoring, and a grammer air-suspended seat. The digger is pre-wired for telematics (GPS/GSM) to enable fleet management directly from headquarters.
Technical Specifications
Below is the primary data for the SANY SY335H Heavy-Duty Digger. All values are measured under ISO 9245 standards.
Heavy-Duty Application Scenarios
Quarrying & Rock Excavation
Fitted with a 1.8m³ heavy-duty rock bucket (with wear plates and side cutters), the digger handles blasted limestone, basalt, and granite ripping. The reinforced arm guard and BOOM foot guard prevent structural damage under severe shock loads.
Large-Scale Earthmoving & Road Construction
In highway earthmoving contracts, the SY335H achieves 320-360 cycles per 8-hour shift when paired with 30-ton ADTs. The auto-power boost mode temporarily increases breakout force to 230 kN for dense clay or compacted aggregate.
Mining Support (Overburden Removal)
With a max digging depth of 7.8 meters and height of 10.5 meters, this heavy digger efficiently removes topsoil and soft overburden in coal or metal mining operations. Dual cone main filters (10μm + 5μm) with water separator protect hydraulics in high-dust environments.
Equipment Q&A
Q1: What is the EXACT lead time for shipping this heavy-duty digger to West Africa or South America?
A1: For firm orders with 30% deposit, we deliver FOB Shanghai or Tianjin within 25-30 working days. Global roll-on/roll-off (RoRo) vessels to Lagos, Luanda, Callao, or Santos average 35-50 days. Container shipping (40ft flat-rack) is available for single units with 15-day preparation time.
Q2: Which genuine wearing parts are included in the free package?
A2: Every SY335H includes one set of cutting edges (4 bolts type), one bucket pin and bushing kit (6 pieces), two track shoe bolts per side, and a complete engine/hydraulic filter kit for the first 500 hours. Extended wearing parts contracts available at $1,850/year.
Q3: Does this heavy digger meet EU / UK / Australia emission standards for 2026?
A3: Yes. The Cummins QSB7 engine is certified EU Stage V, UK PEMS, and Australia DOA compliant. DPF ash cleaning interval is 4,500 hours. We supply a factory-issued Certificate of Conformity (CoC) for each machine.
Q4: What operational training do you provide for our local mechanics and operators?
A4: We deliver (1) A complete multilingual PDF operator manual + parts catalog; (2) 4 hours of remote video training via WhatsApp/WeChat; (3) For fleets over 5 units, a 3-day on-site training by SANY-certified instructor (travel expenses covered by buyer).
Q5: How do we verify the 1-Year Global Warranty and make a claim?
A5: The warranty covers all powertrain and hydraulic major components with no deductible. Claim process: submit failure video + hour meter reading via dealer portal. Replacement parts are shipped from the nearest regional hub (Americas, EMEA, Asia-Pacific) within 96 hours. Warranty certificate delivered with commercial invoice.
