MachDealers Technical Procurement Reference Used Sany Excavators For Sale

CORE PARAMETER VERIFICATION

The elements of the procurement decision chain are brand, category, year, condition, and price, and hours. All fields are filled in by the buyer or declared by the seller. Filter values do not have third party verification by default.

  • Number of Hours: Show Only. Log cross-reference is mandatory in the EU. The threshold for elongation of the track shoes is exceeded >3% and thus indicates real hours over display. Demonstration of Bucket pin bore ovality and of boom cylinder chrome wear pattern – Physical corroborators.

  • Field: condition (seller self assessed). There is no uniform inspection procedure that is tied to any of the conditions listed on this page. Each condition designation is an unverified declaration made in light of an independent inspection report.

  • Year filter: filters down cohort. No record of service, duty cycle or overhaul. Year by itself is NOT a risk variable. The total number of load cycles is.

MODEL COMPARISON MATRIX

  • SY155C — Compact class. Primary Failure Zone: degradation of swing motor seals, wear of stick pins. Priority inspection – hydraulic case drain flow test.
  • SY215C — Mid-range class. Primary failure zone: primary wear of the pump axial pistons, track frame fatigue. Inspections of priority: ECU log hours to display hours delta.
  • SY225C — Mid-range class. Primary fail zone – scoring on the Valve Spool, integrity of the boom foot. Priority for inspection: Boom root/stick joint – MPI.
  • SY245H — Heavy-duty class. Primary failure zone: Elevated wear rate of pistons in the axial piston under the H-series demand cycle whose swing reduction gear backlash has increased. Findings from inspection of the hydraulic pressure and flow bench.
  • SY365H — Heavy-duty class. Upper frame rotary joint mount cracking is a primary failure zone as is the main pump case drain at high-load threshold. Structural MPI plus hydraulic flow test are the priorities for inspection. Both actions mandatory.
Sany H-Series vs C-Series Primary Failure Zone & Inspection Matrix

Data sources for the table above:https://www.heavyequipmentforums.com/forums/excavators.17/

SY245H and SY365H are referred to as “H-series.” Resourcing demand (hydraulic) materially superior to C-series equivalents. Failure cost exposure goes up or down. Pre purchase hydraulic test, minscapa – not an option.
