Used 2021 sany 20ton SY205C crawler excavator

Product Introduction

SY205C is a 20T-class earthmoving excavator product made by Sany Heavy Machinery, adhering to the concept of “high efficiency and fuel saving”, and launching a customer-defined mode, which truly achieves “private customization” of operating habits.
The new generation of SY205C national four machine is fully upgraded around “new power”, “new shape” and “new technology”. It adopts a new electronically controlled main valve with high action sensitivity, low fuel consumption and high cost performance, which can meet customers’ different working conditions job requirements.

Product features

1. Power system
Equipped with a Mitsubishi Fuso 4M50 engine with a power of 118kW, large torque, high durability and faster dynamic response.

2. Hydraulic system
Equipped with Hengli full electric control main valve + Hengli main pump to realize stick regeneration and quick oil return. The boom can realize the function of descending regeneration, which is more efficient and energy-saving. Equipped with a 130cc large-displacement main pump, the engine can use a larger speed range, making it easier to run in an economical fuel consumption zone.

3. DPD+EGR technology
Part of the exhaust gas is circulated into the intake system, mixed with fresh air and then burned to suppress the formation of NOx. The EGR is upgraded from a tubular type to a stacked type, and the cooling is faster.

4. DPC technology
The direct power control technology is adopted to dynamically adjust according to the load, so that all commonly used working gears are moved to the economic zone, and the power matching achieves “what you get is what you need”, reducing waste and realizing energy saving. .

5. Bucket Upgrade
Earthwork buckets are standard, and rock buckets are optional, realizing “one bucket for one situation”, optimizing the bucket shape, and reducing friction. The average resistance in the excavation process is reduced, and the excavation efficiency is increased.

6. Intelligent
At 10 o’clock, the large screen was upgraded again, thinner, more dazzling, clearer, and the system integration is higher. The wireless LAN in the car supports OTA upgrade of 4G network, delayed extinguishment of lamps and lanterns when parking at night, one-key switching of front and back display screens, rear camera and other configurations to ensure driving safety.

7. New air conditioning system
Equipped with a new air-conditioning system, the cooling effect is stronger and the air volume distribution is more reasonable. The air conditioner filter element realizes the cleaning and maintenance inside the car, and the cleaning is easier.
