Sany STC800 Advantages

Outstanding Performance

• Powerful Lifting Capacity: With a maximum rated lifting capacity of up to 80t and a maximum lifting torque of 3469kN·m, the maximum lifting capacity of the fully extended main boom is 12.5t (Val), 13t (Pro), and 15t (Max) respectively in different versions. The maximum lifting height of the main boom can reach 51m, and the maximum lifting radius is 44m. It can easily handle the lifting of various large – scale objects.
• Optimized Boom Structure: The boom is made of U – shaped large – arc cross – section high – strength structural steel. The cross – section size of the main boom is the best in the industry. Through simulation optimization analysis using response surface technology, the deflection of the fully extended boom is reduced by 37%, and the high – frequency performance is improved by 5%. The boom has high strength and good stability, effectively ensuring the safety and efficiency of lifting operations.
• High – speed Operation: The maximum lifting speed of the main winch is 135m/min, the full extension time of the boom is only 130s, and the slewing speed is 0 – 1.5rpm. The fast operation speed can significantly improve work efficiency and shorten the operation cycle.

Energy – saving and Consumption – reducing

• i – eco1.0 System: The induction – free regeneration technology in this system (exclusive to Yuchai version) can achieve self – matching of engine speed to clean carbon deposits, enabling the crane to operate continuously for a long time without shutdown. At the same time, the i – eco fuel – saving technology can match the engine torque based on the operation requirements, improve energy utilization, and reduce operation fuel consumption by 20%, effectively saving operating costs.
• Optimized Power Transmission Matching Technology: The overall layout of the vehicle is compact. By adopting the internationally leading optimized power transmission matching technology, the chassis has strong power and optimal fuel economy. The fuel consumption per 100 kilometers of driving is 44L, with strong fuel – saving ability. In addition, during the upper – vehicle operation, the minimum working idle speed can reach 800rpm. It can identify dynamic power according to load changes, adjust the engine speed, and achieve precise fuel supply, with a comprehensive energy – saving rate of 7.5% during hoisting.

Leading – edge Control

• i – hoisting2.0 System: The newly upgraded intelligent flow control system, combined with dual – pump independent oil supply, makes the control more precise, high – speed, and smooth, facilitating more accurate lifting operations. The slewing working condition self – adaptive technology can adjust the slewing torque in real – time according to the vehicle’s lifting weight, ensuring that the slewing start – stop has no shaking and little impact, and guaranteeing the smoothness of the lifting process.
• Dual – slewing and Dual – pump Technology: The Max version is equipped with a dual – slewing system. Combined with the working condition self – adaptive technology, the slewing stability is 50% ahead. The application of the dual – pump + split – confluence technology makes the combined actions fast and stable, further improving the control performance and meeting the precise lifting requirements under various complex working conditions.
• Human – oriented Cab: It adopts a widened cab with a 10% increase in horizontal space. The cab can be adjusted at an angle of 0 – 20°, and the longitudinal field of vision is increased by 22%. This effectively solves the fatigue problem of operators having to look up during high – altitude lifting, ensuring safe and comfortable operation. At the same time, the cab pedal can be hydraulically telescoped, facilitating operators to get on and off the vehicle.

Intelligent and Comfortable

• i – crane Intelligent System: It has functions such as crane working condition recommendation and one – button boom telescoping for automatic telescoping. It can quickly extend and retract the boom according to the optimal working condition, providing convenience for lifting operations. In addition, the control actions of slewing, telescoping, luffing, and winching can all achieve parameter self – definition configuration, with 3 – gear response, meeting the operation requirements under different working conditions and making the operation more convenient.
• Comfortable Cab Configuration: It is equipped with a new three – dimensional 7 – channel air – conditioning air – supply system, front – mounted air – conditioning buttons, new membrane switch buttons, a mobile phone holder, a cup holder, a rear storage platform, etc. A berth is also standard, and an entertainment screen can be extended, providing operators with a comfortable working environment and effectively relieving operation fatigue.

Safe and Reliable

• High – strength Welded Structure: The boom is made of high – strength welded structural steel, combined with mechanical, electrical, and hydraulic triple protection, as well as automatic telescoping and telescoping buffer technology, ensuring the safety and reliability of the boom during the lifting process.
• Complete Safety Protection Measures: It is equipped with various safety protection devices, such as limit switches and overload protection devices, which can effectively prevent dangerous situations such as overloading and over – travel during the crane’s operation, ensuring the safety of operators and equipment.
• Reliable Chassis Design: It adopts a high – torque engine, heavy – duty axles, etc., with strong load – bearing capacity. The vehicle speed can reach up to 90km/h, and the gradeability can reach 49%, adapting to various complex road conditions and working environments. At the same time, some models adopt a g – type chassis, which optimizes the position of the air storage tank, has a larger approach and departure angle, and can adapt to various harsh road conditions.
