On October 31, SANY Heavy Industries successfully delivered the world's first 9-axle 4000-tonne all-terrain crane SAC40000T, setting a new industry record. This crane achieves the maximum lifting capacity with the least number of axles, setting a new benchmark.
Designed for wind turbine installations, the SAC40000T has a fully telescopic boom length of 81 metres, a jib length of 124 metres, and is equipped with a 350-tonne counterweight for a maximum lifting height of 200 metres. It is capable of lifting 375 tonnes of weight to a height of 100 metres within an 18-metre radius and 200 tonnes of weight to a height of 185 metres within a 30-metre radius, perfectly adapting to the needs of the new generation of turbines.
With the growth of clean energy, there is a growing need for powerful, precise equipment, says the product manager, and the SAC40000T has been launched in response to the increase in turbine power over the next 5-10 years. Its compact, powerful design with a low number of axles makes it more agile and convenient for travelling over rugged mountainous terrain.
The SAC40000T features a 9-axle, 22-metre long chassis, the shortest in its class, and a steering radius of just 16 metres, also the smallest in its class. Its rugged 6+2 dual drive system has a climbing capacity of up to 18 per cent, allowing it to travel on slopes even when boom lifted. It also features quick assembly, allowing the installation and dismantling of a single side superlift to be completed in less than one hour, greatly enhancing work efficiency.
In terms of safety, SAC40000T ensures the safety of super-long boom operation through intelligent boom condition monitoring and active control system. Real-time side-bend angle monitoring alerts operators to potential hazards, while a new signal receiver improves signal stability. The upgraded high-capacity battery also extends the crane's operating time.
All in all, SANY's SAC40000T achieves a lifting capacity of 4,000 tonnes without enlarging the chassis, marking a milestone in the field of heavy lifting. With its record-breaking 9-axle configuration and class-leading manoeuvrability, it sets a new standard for large-capacity, compact all-terrain cranes.
