Zoomlion recently revealed the ZAT4000H763. With a lifting capacity of 4000 tonnes it is claimed to be the most powerful all terrain crane on Earth.
Zoomlion’s ZAT4000H763 has been designed and engineered to keep pace with the predicted increase of requirements in wind farm construction over the next ten years.
The massive crane is designed to handle the lifting for 15.XMW wind turbines on land for the next 10 years. The ZAT4000H763 is capable of lifting 10.0MW wind turbines at a height of 160 metres (m) and 7.0MW wind turbines at a height of 190 metres.
The lifting capabilities of Zoomlion’s ZAT4000H763 are impressive:
• At a height of 125 metres and a radius of 20 metres, the lifting capacity is 317 tonnes.
• At a height of 140 metres and a radius of 22 metres, the lifting capacity is 281 tonnes.
• At a height of 160 metres and a radius of 24 metres, the lifting capacity is 236 tonnes.
• At a height of 170 metres and a radius of 26 metres, the lifting capacity is 218 tonnes.
• At a height of 180 metres and a radius of 28 metres, the lifting capacity is 190 tonnes.
Flexible maneuverability enhancing mobilisation and de-mobilisation
Equipped with a 10-axle chassis with a width of only three metres and a length of just 22.5 metres, which is comparable to a nine-axle equivalent, the ZAT4000H763 can travel on highways and is more suitable for operations in narrow areas such as mountainous wind farms. With the full boom attached, the overall height of the crane is six metres, featuring a low centre of gravity for excellent ground clearance and enhanced safety during heavy-load travel. The 6+2 drive system enables the crane to climb gradients exceeding 20 per cent even with the main boom under heavy loads.
Ultimate operational convenience
The 95.4m ultra-long main boom with dual-side pins requires minimal assembly space for wind turbine installation and other similarly limited working conditions such as infrastructure projects. Autonomous boom raising is possible without the need for auxiliary cranes in wind turbine installation scenarios up to 160m.
Dual motors on a single winch enable rope threading in just 40 minutes per session. In 180m working conditions, the crane can be fully set up in just 30 minutes.
The 1.4m large-distance counterweight displacement reduces the need for two transport trailers, enhancing economic efficiencies. For wind turbine installation scenarios up to 160m, only 22 trailers are needed for large-scale relocations.
