Sany SAC7000S Load Chart PDF + Specifications

The SANY SAC7000S was introduced as one of the company’s flagship large-capacity all terrain cranes, targeting the growing global demand for heavy lifting and wind turbine maintenance equipment. Developed on a seven-axle chassis platform, the crane combines high lifting capacities with improved transport convenience, allowing easier movement between jobsites compared with conventional large lattice boom cranes.

The crane has a maximum lifting capacity of 700 tonnes and is equipped with a seven-section U-shaped telescopic boom. The basic boom length measures 17.2 m and extends hydraulically to a maximum of 90.1 m. The boom system uses a single-cylinder automatic pinning telescoping mechanism designed to improve extension efficiency and boom rigidity. The elliptical boom profile was developed to improve buckling resistance during long-radius lifting operations.

To extend working radius and lifting height, the SAC7000S can be equipped with several jib configurations. The fixed jib system is available in lengths from 20 m to 50 m, while the optional luffing jib can be configured from 24 m up to 90 m. For wind energy applications, SANY also developed dedicated wind power jib configurations ranging from 30 m to 48 m. These configurations were intended to improve lifting capability for 1.5 MW to 2.5 MW wind turbine maintenance and erection projects.

A key feature of the SAC7000S is its Y-shaped superlift device, mounted independently on both sides of the base boom. The system was designed to significantly reduce boom deflection and improve stability during long-boom lifting operations. According to SANY, the superlift arrangement can reduce boom deflection by 20% to 30% while increasing lifting capacity by more than 200% in certain configurations. The crane also uses a counterweight displacement system with three counterweight positions and a maximum displacement of 2 m, reducing transport counterweight requirements by approximately 20 tonnes. Total counterweight reaches 163 tonnes with multiple modular combinations available from 0 t to 163 t.

The SAC7000S 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, crab steering, yaw-free steering, independent rear axle steering, and rear axle lock mode. This arrangement provides excellent maneuverability on confined jobsites and improved highway mobility.

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

The hydro-pneumatic suspension system allows automatic leveling, rigid locking, vehicle lifting, and single-point lifting functions. SANY also incorporated real-time vehicle attitude monitoring and variable damping adaptation technology to improve driving comfort and stability during road travel.

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

The SAC7000S also incorporates a comprehensive electronic monitoring and safety system. The crane uses a PLC-based CAN-BUS control network with real-time fault diagnosis and operational monitoring. Safety systems include anti-two-block protection, load moment indication, anti-tipping warning, wind speed monitoring, hydraulic balance valves, and remote-controlled outriggers. SANY additionally integrated its GCP remote monitoring system, allowing remote equipment diagnostics, operating condition monitoring, and accessory management.
