Crawler Crane

XCMG XGC28000

The XCMG XGC28000 is a colossal 2,000-ton capacity crawler crane, which drew significant attention at the 2010 Bauma China exhibition in Shanghai. A behemoth in the crane industry, it boasts a staggering maximum load moment rating of 28,000 ton-metres, making it ideally suited for heavyweight tasks in nuclear power plant construction, wind farm projects, and the chemical industry.

Rated at a capacity of 2,000 tons with a working radius of 14 meters, the XGC28000’s engineering prowess is displayed through its robust design, capable of handling the most demanding lifting tasks. The crane’s long boom and jib configuration extends to 156 meters, offering versatility for a variety of applications, from constructing nuclear power plants to servicing expansive wind farms and the rigorous demands of the chemical industry.

Product Description

Prototype Testing

The unit showcased at Bauma China was the first prototype, reflecting XCMG’s commitment to rigorous testing and quality assurance. Scheduled for an exhaustive six-month testing phase in 2011, XCMG aimed to ensure the XGC28000 would meet the industry’s highest standards for performance, safety, and reliability.

Optimized for Heavy-Duty Applications

The XGC28000’s design incorporates advanced features specifically for heavy-duty applications. Its main boom and jib configuration, one of the longest available, provide the required reach and flexibility for complex projects where precision and lifting power are paramount.

Future of Lifting

XCMG’s introduction of the XGC28000 at Bauma China represented not just an addition to their product line but a step forward in the evolution of heavy lifting machinery. It embodies the future of construction and engineering projects where the scale and complexity of tasks continue to grow.

Power and Performance

The XCMG XGC28000 Crawler Crane stands out with its innovative dual-engine, dual-power real-time distribution intervention system, incorporating two V-type 8-cylinder Mercedes-Benz engines. These engines conform to the highest emission standards in their class and can switch between single and dual operation based on the project’s demands. This feature not only enhances safety but also significantly boosts fuel economy.

Operator Comfort and Control

With a driving cabin akin to a cockpit, operators are greeted with spaciousness and comfort. The cabin includes a domestic power supply, frequency-converting air conditioning, a refrigerator, and foldable bunks, providing a comfortable working and living environment. Seats with adjustable tilt and distance expand the operator’s field of view. The crane’s dual-engine and hydraulic circuitry, coupled with a backup diesel-electric power supply, offers robust power options for various assembly tasks and field construction needs.

Innovative Lifting Mechanisms

The crane’s superlift counterweight changing mechanism is driven hydraulically, which streamlines operations and saves time during assembly. The optional intelligent adaptive counterweight amplitude control system includes a load feedback feature, automatically determining the superlift counterweight amplitude based on the actual lifting weight. This allows for real-time monitoring of the crane’s center of gravity, ensuring efficient and safe lifting conditions.

Wireless Remote Control System

The powerful remote control system allows for precise installations over long distances, reducing the need for auxiliary personnel and simplifying lifting commands. This system enhances safety and efficiency during complex lifting operations.

Advanced Technology Integration

The crane employs specialized electro-hydraulic proportional control technology, ensuring stepless speed regulation and highly accurate control, meeting the precision requirements of significant equipment installations. In addition, the crane features a specially developed six-row axial roller heavy-duty slewing bearing, co-developed with Germany’s Rothe Erde to support its exceptional performance.

Design and Transportation

The crane’s design includes a front and rear split turntable, using a concentric circular distribution hydraulic synchronous power pin for connection to the crawler chassis, making the entire structure more compact and assembly more convenient. Safety devices, two large color screens for system operation selection, and real-time parameter monitoring ensure safe operation of the crane.

Milestones

The gigantic 2000 ton crawler crane has again set a new record by lifting a 1,340-ton hydrocracking reactor in Sinopec’s Quanzhou refinery base in September 2009. The crane uses 60m heavy-duty boom, 340-ton turntable counterweights, 111-ton crane body counterweights, 640-ton super lift counterweights in 30m super lift radius and lifted the hydrocracking reactor at a 14m working radius. It broke its previous record of lifting a load of 958 ton in Maoming, Guangdong.
