2. Powertrain System

The SY75C is equipped with an original Isuzu 4JG1 series water-cooled 4-cylinder turbocharged diesel engine, which has the following features:

Strong low-speed torque reserve, stable operation even in high-altitude (below 4,500m) and low-temperature (-30℃) environments, supporting one-key cold start.
Equipped with an intelligent idle control system, which automatically reduces engine speed when the equipment is on standby, cutting fuel consumption by 5-8% compared with competitors of the same class, and the comprehensive operating fuel consumption is only about 5L per hour under standard working conditions.
3-stage fuel filtration system, adapts to low-quality fuel in underdeveloped regions, effectively reducing engine failure rates.

3. Hydraulic System

It adopts SANY's self-developed positive flow control hydraulic system, matched with first-tier brand core components (Kawasaki/Rexroth main pump, main valve):

Fast response speed, high action accuracy, excellent coordination of composite actions (simultaneous digging, slewing and walking will not jam), operating efficiency is 10% higher than similar products.
Built-in slewing buffer valve, smooth start and stop of slewing action, reduces jitter during operation, and improves operation accuracy.
Low pressure loss design, effectively reduces hydraulic oil temperature rise, extends the service life of hydraulic components.

4. Structural Durability

Boom, arm and X-type undercarriage are made of high-strength wear-resistant steel, all welded joints are treated with stress relief, and the boom is reinforced with extra wear plates, which can adapt to long-term heavy load conditions, and the structural life is more than 15,000 hours.
Sealed heavy-duty crawler chain, wear resistance is 30% higher than ordinary crawlers, suitable for complex terrain such as gravel, mud and mountain roads.
The standard bucket is made of NM400 wear-resistant steel, with replaceable high-hardness bucket teeth, reducing later replacement costs.

5. Operator Comfort

The cab meets ROPS (Roll-over Protective Structure) and FOPS (Falling Object Protective Structure) certification standards:

High sealing performance, the operating noise inside the cab is only 72dB, which is far lower than the industry average.
Equipped with fully adjustable air suspension seat, ergonomic control handle with low operating force, which can effectively reduce the fatigue of long-term operation.
Standard fully automatic constant temperature air conditioner, 8-inch intelligent LCD display (supports real-time viewing of operating parameters, fault alarms, fuel consumption data), USB charging port, radio and large storage space.
Ultra-wide panoramic glass design, small blind area of vision, the wiper covers 90% of the front window area, ensuring clear vision in rainy and snowy weather.

6. Maintenance Convenience

All daily maintenance points (oil filter, fuel filter, air filter, hydraulic oil filter) are arranged at ground-accessible positions, no need to climb the car for maintenance, which greatly improves maintenance efficiency.
The hydraulic oil replacement cycle is 5,000 hours, which is 2 times longer than similar products, reducing the later use cost.
Equipped with SANY SYNC remote telematics system, which supports real-time monitoring of equipment location, operating status, fault warning, and remote diagnosis by after-sales personnel, effectively reducing downtime.
SANY has more than 6,000 after-sales service outlets around the world, with fast supply of spare parts, and the standard warranty policy is 2 years or 3,000 working hours (adjustable according to regional policies).

7. Applicable Scenarios & Optional Attachments

The compact size of the SY75C makes it suitable for operation in narrow spaces, and its main application scenarios include:

Urban municipal construction: trench digging, pipeline laying, road maintenance
Landscaping: tree pit digging, site leveling, garden renovation
Small earthwork: foundation excavation of civil buildings, site clearing
Agricultural construction: farmland water conservancy renovation, greenhouse construction
Small demolition, material handling and other operations

Optional attachments: hydraulic breaker, quick coupler, log grapple, auger, desilting bucket, dozer blade, etc., to meet the needs of different working conditions.

Core Competitive Advantages

10% higher operating efficiency and 8% lower fuel consumption than similar products, leading in comprehensive return on investment
Low failure rate, strong adaptability to harsh working conditions
Low maintenance cost, perfect global after-sales service system
Comfortable operating experience, meeting the needs of long-term continuous operation
