SANY SY335H Specifications and Used-Buyer Checklist
Introduction: Identify the Version First
The SANY SY335H is a mining-oriented excavator used in quarry and heavy earthmoving work. Buyers should identify the year, serial number, engine and front attachment before comparing specifications or offers.
The reference below is SANY's March 2016 SY305H/SY335H brochure, not a universal specification for all later SY335H or SY335H PRO machines. Its SY335H column lists 34,300 kg, a 1.5 m³ bucket and 190.5 kW rated power. Verify later or modified machines against their own plate and documentation.
This is a specification-based buying guide, not a measured field test. It separates manufacturer reference data from the inspection and quotation required for an individual used machine.
1. General Overview & Positioning
Choose the SY335H by required production, reach, truck matching and transport limits. A nominal size class does not establish the capacity of every bucket or lifting configuration.
Key positioning points:
-
Operating Weight:34,300 kg (March 2016 brochure reference)
-
Bucket Capacity:1.5 m³ (same brochure configuration)
-
Primary Applications: Quarrying, aggregate loading, overburden removal, foundation excavation, dam & railway earthwork, light demolition
-
Target Users:Contractors comparing production requirements, local parts support and total repair exposure

|
Before importing, confirm engine identification, local parts access, cold-start behavior, leaks and hot loaded operation. The engine family alone does not establish condition or remaining life.
Inspect filters and water separators and use the fuel quality required by the applicable manual. Filtration is not permission to use unsuitable fuel.
3. Hydraulic System and Functional Checks
The reference brochure describes positive flow control (PFC) hydraulic system and an integrated engine-pump-valve control system. For a used machine, inspect the installed pumps and valves and test their operation at normal working temperature.
Reference performance and checks:
-
Main Pump:Confirm pump model and flow from the matching manual; test by a qualified technician
-
Main Valve:Confirm the installed valve identification and repair history
-
Maximum Digging Force (Bucket):220 kN (brochure reference)
-
Maximum Arm (Stick) Digging Force:170 kN (brochure reference)
-
Swing Speed:9.5 rpm (brochure reference)
-
Travel Speed:5.2 / 3.4 km/h (high / low, brochure reference)
-
Gradeability: 70% (35°)
-
Hydraulic Tank Capacity:Verify the refill capacity in the matching operator manual
Functional checks before approving a used unit:
-
Combined boom, arm and swing movements after the oil warms
-
Leakage, abnormal noise, overheating and cylinder drift
-
Digging response with a safe load under the correct test procedure
-
Attachment flow, pressure, return line and coupler compatibility
Evaluate fuel and cycle performance with a defined task, operator, attachment and material. This guide does not promise a fixed saving over competing machines.
4. Structural Durability & Undercarriage
Mining and quarry work impose severe stress on booms, arms, and undercarriages. The SY335H addresses this with:
-
Reinforced Boom & Arm: Inspect attachment points, welds and previous repairs. Manufacturer durability claims do not certify the remaining life of a particular used boom or arm.
-
X-Frame Undercarriage: Measure track components and inspect the frame; assess stability using the correct configuration and lifting chart.
-
Track Shoes: Check the fitted shoe width and grouser type against the intended ground conditions.
-
Four-Wheel-One-Belt (Track Chain, Shoes, Rollers, Idlers, Sprocket): Inspect chain, rollers, idlers and sprockets individually, recording dimensions and replacement history.
-
Minimum Ground Clearance: 550 mm — helps avoid hang-up on boulders or debris.
Ground pressure depends on configuration and ground contact. Check the site bearing capacity and avoid assuming the nominal machine class guarantees safe operation on soft ground.
5. Operator Cabin & Ergonomics
Check the actual cab equipment and protective certification rather than assuming every year has the same options:
-
Seat, suspension and belt checked for condition and adjustment
-
Automatic climate control A/C & heating
-
Color LCD monitor panel displaying fuel level, service intervals, hydraulic oil temp, fault codes, and working mode selection
-
Low-noise & dust-sealed interior with intact seals and serviceable windows
-
Ample legroom & wide field of view, especially to the right-side trench and attachment tip
-
Optional: Confirm camera, radio and telematics equipment and any subscription or access requirements
Test controls, warnings, visibility and emergency exits during inspection. Cab comfort should be assessed on the actual unit.

7. Typical Applications
Thanks to its balanced size and reinforced structure, the SY335H is commonly seen in:
-
Quarry & Aggregate Loading — Loading blasted granite, limestone, sand & gravel into 20–30 ton dump trucks.
-
Open-Pit Mining / Overburden Removal — Stripping topsoil and soft overburden before heavier shovels take over.
-
Major Earthmoving Projects — Highway/subgrade cut-and-fill, dam foundation excavation, railway embankment work.
-
Rock Breaking (with Breaker) — When fitted with a hydraulic hammer for secondary breaking of oversize boulders.
-
Demolition & Sorting — With optional quick-coupler, grapple, or shear for urban demolition cleanup.
8. Measuring Fuel Use and Productivity
Use a recorded working test; this article contains no unit-specific fuel measurement:
-
Fuel Consumption: Record fuel added, engine hours, productive hours, idle time and task. Report the measured litres per hour rather than assigning a rate from model name.
-
Cycle-Time Comparison: Compare equivalent material, swing angle, truck position and operator. No fixed productivity advantage is assumed.
-
Fuel-Budget Calculation: Multiply the measured fuel difference per hour by the planned annual hours and local fuel price. Include maintenance and repair exposure in the total.
9. Maintenance & Serviceability
Routine service points are grouped for ground-level access:
-
Centralized greasing points for boom/arm pivots
-
Wide-opening side doors & engine hood for radiator, filter, and dipstick access
-
Easy-to-clean aluminum parallel-flow radiator with dust guard
-
Extended service intervals for hydraulic return filter, air cleaner (dual element), and fuel filters
-
Telematics: Confirm fitted monitoring hardware and access. Where available, recorded hours and operating data can support maintenance planning; do not assume a used unit includes an active account.
10. New vs. Used Market — Buyer Considerations
New Units
Before buying a new unit, confirm in writing:
-
Warranty issuer, coverage, start date and whether export affects support
-
Full operator & service manuals
-
Access to SANY's growing global dealer support network
-
Optional attachments (rock bucket, teeth, ripper, breaker, etc.)
Used Units (Common Export Spec)
When purchasing a used SY335H for export or secondary-market use, pay special attention to:
-
Undercarriage Remaining Life - record measured wear and the expected repair budget; do not infer a fixed remaining life from a sales percentage
-
Hydraulic System — check for abnormal noise, overheating, slow composite action, or leakage at pump/valve seals
-
Engine Blow-by & Exhaust - diagnose smoke and blow-by with appropriate tests rather than assuming every symptom requires an overhaul
-
Service History — verified hour meter, regular greasing, filter changes
-
Cab Electronics — monitor functionality, A/C compressor condition
How to compare used-machine quotations:
-
Match the exact model, year, serial number, recorded hours and inspection scope.
-
Separate machine price, preparation, inland transport, loading and freight.
-
Confirm quotation validity, payment terms and destination charges.
This article does not state a current stock price. Use a written quotation for the exact available machine and agreed export terms.
