Key Features & Advantages

1. High Efficiency & Low Fuel Consumption

It is equipped with SANY’s proprietary positive flow hydraulic system, which delivers 15% faster response speed than traditional negative flow systems, and reduces overall fuel consumption by 10% – 15% compared to peer models of the same class. The built-in auto-idle and auto engine shutdown functions further cut unnecessary fuel waste during standby periods, with a typical hourly fuel consumption of only 3 – 5 L under light to medium working conditions.

2. Excellent Operational Performance

The optimized hydraulic control logic delivers outstanding micro-maneuverability, suitable for precision operations such as trench digging, pipeline laying and landscaping. The operating joystick is designed with low force feedback, reducing operator fatigue after long hours of work. The reinforced undercarriage and stable weight distribution also ensure smooth operation on sloped, muddy or uneven construction sites.

3. Superior Durability

All core structural parts (boom, arm, travel frame) have passed 10,000+ hours of extreme fatigue testing, adapting to harsh working conditions including gravel yards, small mines and demolition sites. Key hydraulic components (pump, valve, motor) are sourced from top international suppliers, with a dust and waterproof rating of IP67 for core electrical parts, extending the service life of the whole machine.

4. Operator Comfort

The cab is ROPS/FOPS certified, providing reliable protection against rollover and falling object risks. The internal noise level is controlled below 75 dB, with a fully adjustable air-suspension seat, high-efficiency heating and cooling air conditioning, USB charging port and large storage space. The 7-inch high-definition display shows real-time operating data and fault warnings for easy monitoring.

5. Easy Maintenance & Low Operating Cost

All daily maintenance points (oil filters, fuel filters, hydraulic oil ports, air filter) are designed to be accessible from the ground, no climbing required. The hydraulic oil replacement interval reaches 5,000 hours, which is 2 – 3 times longer than competing models, greatly reducing long-term maintenance costs. It is also equipped with the SANY SYNC remote management system, supporting real-time monitoring of equipment location, working hours, fuel consumption and fault warnings, convenient for fleet management.

6. Comprehensive Safety Configurations

Standard configurations include audible travel and swing alarms to remind surrounding personnel, multi-position emergency stop buttons, and overheat protection for the engine and hydraulic system. A rear-view camera is available as an option to eliminate operating blind spots.

Application Scenarios

The SANY 75 is highly versatile, suitable for a wide range of working scenarios:

Municipal engineering: Trench digging, pipeline laying, road repair and urban greening
Agricultural construction: Farmland leveling, irrigation canal digging, rural housing foundation construction
Small demolition: Concrete breaking, small building demolition (with hydraulic breaker)
Material handling: Timber/grass grabbing, sand and gravel loading (with grab attachments)
Landscaping: Pit digging for planting, terrain shaping, site clearing
