Overview

The 4000-tonne mobile crane, specifically the XCA4000 by XCMG, represents a significant milestone in crane technology, particularly tailored for the installation of large wind turbines.

Key Specifications

Capacity and Lifting Capabilities

• The XCA4000 has a rated capacity of 4,000 tonnes, although it is not capable of lifting this full load in practical scenarios. It can lift 230 tonnes to a height of 170 metres, making it ideal for installing turbines of 10 MW or more[4][5].
• The crane can handle specific loads at different heights and radii, such as lifting a 130 tonne nacelle, a 40 tonne wheel hub, and three 95 metre blades each weighing 28 tonnes to a height of 162 metres[1][5].

Physical Dimensions and Configuration

• The crane is equipped with 11 axles, making it the world’s first 11-axle crane.
• It has an overall width of 3.68 metres in transport mode, which poses logistical challenges for road travel[1][4].
• The crane features a six-section 85 metre boom, extendable to greater heights with the addition of a heavy-duty jib. For example, it can be rigged with an 85 metre heavy-duty jib on top of its fully extended boom[1].

Operational Features

• The crane is designed with a superlift system and can be equipped with up to 300 tonnes of counterweight to enhance its lifting capabilities.
• It includes advanced safety features such as more than 12 sensors on the boom to detect hazards in real-time and eliminate them through the control system[5].

Transportation and Mobility

• Despite its massive size, the crane can travel on roads with its main boom and outriggers onboard, although it is limited by its weight and dimensions. It can travel at full road speed of 60 kph when the superstructure and outriggers are onboard, but this speed is significantly reduced when the full Superlift device is added[3][5].
• The crane has a gradeability of 16% and can travel with an all-up weight of 400 tonnes when fully configured[5].

Practical Applications

Wind Turbine Installation

• The primary application of the XCA4000 is the installation of large wind turbines. Its capacity to lift heavy components to significant heights makes it an essential tool in wind farm construction projects[1][4][5].

Efficiency and Safety

• XCMG claims that the new technology and design features of the XCA4000 result in a 20 to 30% reduction in turbine installation time, enhancing both efficiency and safety[5].

Design and Engineering

Engineering and Planning

• The development of the XCA4000 involved extensive planning, designing, and engineering. The crane’s complex system includes advanced hydraulic systems, a robust chassis, and sophisticated control mechanisms[3].

Comparison with Other Cranes

• The XCA4000 differs significantly from smaller lattice cranes or other telescopic cranes. While it offers unparalleled lifting capacity and height, it is less versatile and more specialized for wind turbine installations. European manufacturers typically do not produce telescopic cranes beyond 1,200 tonnes, highlighting the unique approach taken by Chinese companies like XCMG[1].

Conclusion

The 4000-tonne mobile crane, specifically the XCA4000 by XCMG, is a groundbreaking piece of equipment designed to meet the demanding requirements of modern wind turbine installation. Its impressive lifting capacity, advanced safety features, and specialized design make it an invaluable asset in the construction of large wind farms.
