Global leader: Jiangxi has successfully developed "GBM gearless Crane"

according to the information of Jiangxi Provincial Science and Technology Department, the specific type of fixture to be used depends on the materials you tested. An enterprise in Jiangxi has successfully developed "GBM gearless Crane", which integrates the functions of motor, reducer, drum, transmission, why paper enterprises have high inventory recently, and so on, It has broken through the technological bottleneck that has plagued the advanced manufacturing countries in Europe and the United States for more than 80 years. According to the Jiangxi Provincial Department of science and technology, an enterprise in Jiangxi has successfully developed GBM gearless crane, which integrates the functions of motor, reducer, drum, transmission mechanism and so on, breaking through the technical bottleneck that has plagued the advanced manufacturing countries in Europe and the United States for more than 80 years

it is reported that this crane was developed by Jiangxi Gongbu Machinery Co., Ltd. to subvert the traditional four link mechanism of double beam crane. Now, it has been selected into the first major technical equipment demonstration project in China's industry. At the same time, it has also been selected into projects such as chang'e-3 detector and cloud computer

Yu Liansheng, chairman of Gongbu Machinery Co., Ltd., introduced that the traditional crane is equipped with a reducer. Under the condition of long-term and high-intensity load, the datum of assembly gradually changes, resulting in oil leakage, loud noise, broken teeth and other phenomena. Since the 1930s, Europe and the United States and other countries have begun to study gearless crane technology, but they have never made a breakthrough

The core component of GBM gearless crane is the lifting trolley, which is small in size and light in weight. Taking the 32 ton crane lifting trolley as an example, the traditional crane lifting trolley has a dead weight of 10.97 tons and a volume of 16.49 cubic meters, while the GBM gearless crane lifting trolley has a dead weight of only 5.46 tons and a volume of 7.56 cubic meters, both of which are reduced by more than 50%. In addition, its safety performance, overload protection, error correction protection and millimeter level intelligent control level are also leading in the world

at present, the device has applied for more than 20 international and domestic patents. It can be used not only in civilian industries such as elevators and cranes, but also in military industries such as helicopters, submarines and tanks
