A few days ago, the genma 3,000-ton full-slewing offshore crane (hereinafter referred to as the offshore crane) designed and built by Rainbow Heavy Machinery successfully completed the heavy-duty test and was delivered to the customer.
The Genma offshore crane is installed on the self-propelled full-slewing crane vessel "Tianfeng 10", which is mainly used for the hoisting of offshore wind power monopile foundations, jackets, platform modules, booster station components and large offshore steel structures. In the fixed tail crane state, the maximum lifting capacity of the equipment can reach 3,000 tons, the maximum lifting height is up to 110 meters, and the equipment is equipped with lifting, luffing and 360° continuous full rotation and other operation functions, which can fully meet the operation needs of offshore wind power and other engineering construction.
Light weight
In the product structure design stage, the Genma product design team optimized the design of the equipment structure, and carried out fine steel structure calculation verification, which successfully reduced the overall weight of the Genma marine crane and realized the ratio of the crane's self-weight to its maximum lifting capacity from 1:1The improvement of 25 to 1:1 has successfully filled the technological gap in this field in China and greatly narrowed the gap with the international advanced level. Thanks to its reduced weight, the machine can more easily lift goods to farther positions, increasing the efficiency of the Genma Marine Crane.
Stable operation
It is worth mentioning that the Genma marine crane equipment adopts a high-power closed hydraulic drive system for the first time in a large-scale full-swing floating crane project in China. This drive system has many advantages such as reliable drive mechanism, oil supply system and stable oil supply pressure, which can greatly improve the work efficiency of the equipment, reduce energy consumption, and enable it to complete various tasks quickly and efficiently under the premise of ensuring stable power output.
Precise control
In terms of electrical, the Genma 3,000 ton full-slewing offshore crane adopts an advanced PLC control system and stepless speed regulation. The application of these technologies makes the operation of the equipment smoother, and can achieve high-precision and high-reliability control tasks. At the same time, the equipment can automatically adjust the speed according to the load situation, and automatically adapt to the no-load high-speed and heavy-load slow operation modes, so as to further improve the operation efficiency and safety of the equipment. The application of these technologies has greatly improved the performance and intelligence of the genma 3,000 ton full-slewing marine crane.
With its excellent design and construction capabilities and technical strength, Rainbow Heavy Machinery has successfully built the genma 3,000-ton full-slewing offshore crane with multiple advantages, injecting new impetus into the further development of China's offshore wind power industry. In the future, Rainbow Heavy Machinery will continue to give full play to its technological advantages and innovation capabilities, continue to provide high-quality product solutions and services for industry customers, and jointly promote the development of the offshore engineering industry.
