Sany SAC7000S7 Load Chart PDF + Specifications

The SANY SAC7000S7 entered the large-capacity all terrain crane segment as one of the manufacturer’s flagship seven-axle machines, aimed particularly at heavy infrastructure, petrochemical construction, and wind turbine maintenance projects. The crane belongs to SANY’s new-generation high-capacity all terrain range and was engineered with a focus on combining long boom capability with transport convenience.

The crane has a maximum lifting capacity of 700 tonnes and is equipped with a seven-section U-shaped telescopic boom. The boom measures 17.2 m in its basic configuration and extends hydraulically to a maximum length of 90.1 m. To further extend working reach and lifting height, the crane can be equipped with a fixed jib ranging from 20 m to 63 m and an optional luffing jib system with combinations from 24 m up to 90 m. These configurations allow the SAC7000S7 to perform complex lifts at significant radii and elevations, especially in wind energy applications involving 1.5 MW to 2.5 MW turbine maintenance.

One of the major technical highlights of the SAC7000S7 is its Y-shaped superlift device. Unlike conventional superlift arrangements, the SANY system is independently mounted on both sides of the boom base and can be assembled without the need for an auxiliary crane. The system substantially improves boom stiffness and reduces boom deflection under load. According to SANY, the superlift arrangement can reduce long-boom deflection by 20% to 30% while increasing lifting capacity by more than 200% in certain long-boom configurations.

The crane also adopts SANY’s adjustable counterweight technology. Total counterweight reaches 163 tonnes, with several modular configurations available between 0 t and 163 t. The counterweight system offers three slewing radii of 6.8 m, 7.8 m, and 8.8 m to optimize lifting performance and site adaptability. The adjustable counterweight displacement system allows a maximum displacement of 2 m, reducing the amount of transport counterweight required by as much as 20 tonnes.

The SAC7000S7 is mounted on a seven-axle all terrain carrier with a 14×8 drive configuration. Axles 1 through 4 are driven, while all seven axles are steerable. The crane offers six steering modes, including normal road steering, all-wheel steering, crabbing, independent rear axle steering, and yaw-free steering for confined jobsite maneuvering. The hydro-pneumatic suspension system provides automatic leveling, height adjustment, rigid locking, and single-point lifting functions, greatly enhancing driving comfort and off-road capability.

Power for the carrier is supplied by a Mercedes-Benz OM502LA V8 diesel engine producing 480 kW at 1,800 rpm with a maximum torque of 3,000 Nm at 1,300 rpm. The engine complies with EU Stage III B emission regulations. The drivetrain is matched with a 12-speed automated manual transmission designed to provide both low-speed climbing capability and high-speed road travel. The SAC7000S7 can travel at speeds up to 70 km/h and has a maximum gradeability of 34%.

The crane superstructure is powered by a separate Mercedes-Benz inline six-cylinder diesel engine rated at 205 kW at 2,200 rpm and producing 1,100 Nm of torque. Hydraulic functions are managed through a combination of open and closed hydraulic circuits with electric proportional control technology. The hoisting system achieves a maximum single-line lifting speed of approximately 130 m/min, while full boom extension or retraction requires approximately 1,200 seconds. The boom luffing system can raise or lower the boom fully in approximately 95 seconds, and slewing speed reaches 0.9 rpm.

The crane incorporates a wide range of intelligent safety and operational technologies. Its electronic control architecture is based on a PLC and CAN-BUS network system with integrated fault diagnosis and real-time monitoring. The load moment indicator system provides lifting accuracy within ±3%, while additional systems include anti-two-block protection, wind speed monitoring, anti-tipping warning, hydraulic balance valves, and remote-controlled outrigger operation.

In terms of transportability, the SAC7000S7 was specifically designed to improve intersite mobility compared with traditional large-capacity all terrain cranes. SANY states that the crane can travel with boom and outriggers installed at speeds up to 50 km/h while maintaining an overall transport height of approximately 4.2 m, allowing the crane to pass through most Class III and IV highway bridges and tunnels without removing the superlift device.

Operational Note

It should be noted that the luffing jib configuration of the SAC7000S7 is designed to operate only in conjunction with the Y-shaped superlift system. At present, SANY does not offer a configuration allowing independent luffing jib operation without the superlift device installed.
