At the coal unloading site of Nantong Zhongtian Haoyang Wharf, two GENMA bridge-type grab ship unloaders are running at full power, extending their "giant hands", quickly grabbing coal from the cabin, and gently shaking it off at the hopper. Correspondingly, the coal is continuously transported to the rear yard through the lower conveyor belt.
In 2021, Rainbow Heavy Machinery independently designed and built two GENMA bridge-type grab ship unloaders for Zenith Steel Group（Nantong) Co., Ltd., with a rated productivity of 1,500 tons/hour and a maximum productivity of 1,800 tons/hour, which can be used to easily unload 50,000-ton bulk carrier.
Thanks to the meticulous design by GENMA designers, the device integrates a litany of advanced technologies and configurations, and has obvious advantages in overall performance and user experience.
High efficiency and stability: GENMA bridge-type grab ship unloader adopts AC frequency conversion speed control system, the equipment starts and brakes smoothly, and the response is sensitive, which can effectively improve production efficiency and provide a reliable guarantee for stable production rhythm;
High degree of automation: The GENMA bridge-type grab ship unloader has the function of automatic control of the grab. The control system of the whole machine can automatically plan the optimal operating trajectory of the grab according to the boundary conditions set by the driver, and complete the grab operation in an automatic, safe and efficient manner. Meanwhile, the labor intensity of the driver can be greatly reduced;
High safety: GENMA has a complete safety protection system, such as anti-collision design, automatic fire extinguishing system, emergency escape device, monitoring system device, etc. Among them, equipment status monitoring and fault diagnosis technology can not only accurately identify the operating status of equipment, obtain real-time monitoring of the operation status, and at the same time, the equipment status can be evaluated according to various real-time data, and targeted equipment management and control plans can be made to provide guarantee and support for the safe operation of the equipment;
High environmental protection: The equipment grab is equipped with a material blanking recovery device, which can recover the materials that the equipment may scatter between the ship and the wharf during operation, thereby improving the environmental protection level of the wharf operation. Given the multi-level intelligent high-pressure spray dust suppression system according to the material characteristics, the equipment can effectively reduce the dust pollution generated during material unloading and conveying, keep the wharf environment clean and tidy, and adjust the spray intensity as per the material dust conditions, which is both environmentally friendly and energy-saving.
The driver's cab is an important part to ensure the safe operation of the driver. In addition to providing the driver with an operating space, it is also closely related to the driver's operation comfort. Due to the design with ergonomic principles, the driver's cab of GENMA bridge-type grab ship unloader can move independently, has spacious space and wide field of vision. The driver's cab is equipped with an intelligent operation screen, a walkie-talkie and a camera monitoring system, so that the operator can grasp the operation of the equipment in real time and drive safely.
Since the delivery of the equipment, the two GENMA bridge-type grab ship unloaders have unloaded 4 million tons of coal accumulatively. Owing to stable operation and sound target parameters, the equipment has played a positive role in increasing port production and building a green port.
"The GENMA ship unloader has good performance, few faults, and is very convenient to operate. It takes a month to get started with this machine, and the cab is spacious and comfortable, fully equipped, and very user-friendly." An experienced driver who has worked in the port for 15 years is full of praise for the GENMA bridge-type grab ship unloader.
GENMA bridge-type grab ship unloaders are widely used in the unloading operations of bulk cargo ships in various ports and wharfs with the advantages of excellent performance, safety and reliability, energy saving and environmental protection. In the future, Rainbow Heavy Machinery will adhere to technological research and development innovation, continuously promote product transformation and upgrading, and provide more high-quality and professional solutions for material handling operations in ports and wharfs.
