Sany SY215C Used Crawler Excavator Machine for Construction Projects
Product Information
Procuring a heavy-duty used Sany SY215C crawler excavator provides general contractors, civil engineering firms, and earthmoving operators with an exceptionally robust machine for demanding site operations. Weighing 21,900 kg, this mid-sized commercial excavator is widely recognized for combining aggressive digging force with low operational fuel consumption. By sourcing a thoroughly inspected pre-owned unit, overseas procurement teams gain access to high-tier operational efficiency while significantly optimizing machinery capital expenditure. Our specialized yard conducts multi-point technical evaluations, hydraulic load testing, and structural reconditioning on every unit to guarantee immediate deployment upon delivery.
Advanced Hydraulic Engineering and Structural Capabilities
Every second-hand earthmoving unit in our inventory undergoes extensive mechanical verification by certified heavy machinery technicians to ensure compliance with factory working standards.
Mitsubishi 4M50 High-Torque Powertrain
At the core of this 21.9-ton excavator is the original Mitsubishi 4M50 turbocharged engine. Featuring a 4-cylinder, water-cooled configuration with a 4.9L displacement, this engine generates a rated power output of 118 kW at 2000 rpm. Designed for durability under continuous duty cycles, the powertrain delivers high torque at low engine speeds, effectively reducing hourly fuel burn while maintaining steady hydraulic pump pressure.
Kawasaki Hydraulic Main Pump and Valve System
The hydraulic architecture integrates genuine Kawasaki main pumps and distribution valves, ensuring smooth multi-function coordination during complex excavating cycles. The system produces a bucket digging force of 138 kN and a stick digging force of 103 kN. Paired with a standard 1.1 m³ heavy-duty bucket, the machine delivers rapid trenching, loading, and backfilling capabilities across hard soil and rocky terrain.
Reinforced Undercarriage and Track Assembly
Built on a heavy-duty X-frame undercarriage, the machine features a travel speed range of 3.3 to 5.4 km/h and a rotation speed of 11 rpm for quick cycle times. With a 35°/70° gradeability rating and a generous 390L fuel tank capacity, this crawler excavator maintains maximum traction and stability on steep slopes, muddy earthworks, and unpaved aggregate yards.

Primary Industrial Application Scenarios
Civil Infrastructure and Foundation Trenching
With a maximum excavation depth of 6,600 mm and a maximum vertical digging depth of 5,980 mm, this unit excels in deep foundation footing, basement excavation, and municipal drainage installations. Precise joystick controls allow operators to trim trench walls cleanly, reducing manual cleanup work.
Mass Earthmoving and Truck Loading
Featuring a maximum excavation height of 9,600 mm and an unloading height of 6,730 mm, the equipment easily clears high-sided haul trucks and dump trailers. The 1.1 m³ bucket capacity paired with 11 rpm rotation speeds ensures rapid truck turnaround times on large-scale commercial earthmoving sites.
Road Construction and Quarrying Operations
The 138 kN bucket digging force provides necessary breakout power when working in compacted subgrade, crushed stone, and road bed demolition. The heavy track assembly absorbs continuous shock loads when operating hydraulic breakers or working along broken pavement cuts.

Frequently Asked Questions (FAQ)
How is the hydraulic main pump tested before export shipment?
Our certified technicians connect diagnostic pressure gauges directly to the Kawasaki main pumps to test working relief pressures under full load conditions. We verify that flow rates and valve spools respond without hydraulic lag or thermal pressure drop.
Can the machine be customized with additional hydraulic piping for attachments?
Yes, our yard technicians can install extra auxiliary hydraulic lines on the boom and arm. This allows the excavator to power hydraulic breakers, concrete pulverizers, or tilt-rotators based on your specific project demands.
What documentation is provided for international customs clearance?
Every export order includes a full commercial invoice, detailed packing list, original Bill of Lading, and pre-shipment technical inspection report to facilitate smooth customs processing at destination ports.
What are the exact shipping dimensions for freight transport planning?
The transport dimensions are 9,680 mm in length, 2,980 mm in width, and 3,440 mm in height, with an operating weight of 21,900 kg. This allows for standard flat-rack containerization or RoRo ocean freight.
What payment terms apply to international heavy machinery purchases?
We process international orders via standard Wire Transfer (T/T). Orders are confirmed upon receipt of a commercial deposit to initiate inspection and freight preparation, with the balance settled upon presentation of shipping documents.
