Frequently Asked Questions

Everything you need to know about the SANY SCC4000A-2 Heavy Crawler Crane

The SANY SCC4000A-2 has a maximum rated lifting capacity of 400 Tonnes with a lifting moment of 2,400 t·m in standard configuration, and 5,280 t·m with superlift device — making it suitable for heavy petrochemical, wind energy, nuclear, and large infrastructure projects. with a lifting moment of 150 t·m (1,471 kN·m), making it suitable for heavy construction, infrastructure, and industrial lifting on soft or uneven ground.

The SCC4000A-2 features a main boom of up to 40 m and a fixed jib of 15.25 m. In the maximum boom and jib configuration, the combination reaches 31 m boom plus 15.25 m jib for extended vertical reach.

The SANY SCC4000A-2 is powered by a 129 kW diesel engine, providing the power needed to handle 45-tonne lifts and operate on challenging terrain conditions typically encountered on construction and industrial sites.

The SANY SCC4000A-2 can handle up to 40% gradeability on its crawler track system, allowing it to manoeuvre on steep slopes and uneven ground at construction sites where wheeled cranes cannot operate safely.

The crawler track system of the SCC4000A-2 distributes its weight over a large footprint, enabling operation on soft ground without the need for outrigger mats. The 40% gradeability and self-propelled mobility mean it can travel across site terrain without requiring a separate carrier vehicle.
