Focusing on intelligence and building a "double promotion" platform, the 2023 Jiangsu Construction Hoisting Finals came to a successful conclusion

From August 31st to September 1st, the final of the 2023 Jiangsu Provincial Vocational Skills Competition for Millions of Urban and Rural Construction Workers was successfully held in Kunshan, Jiangsu. 55 players from 11 municipalities in Jiangsu Province competed on the same stage and showed their style.

The competition was jointly sponsored by the Jiangsu Provincial Department of Housing and Urban-Rural Development, the Jiangsu Provincial Federation of Trade Unions, and the Jiangsu Provincial Department of Education, guided by the Jiangsu Provincial Department of Human Resources and Social Security, undertaken by the Jiangsu Construction Industry Association and Kunshan Housing and Urban-Rural Development Bureau, and co-organized by Sany Heavy Industry Co., Ltd. and Nanjing Anzhidao Intelligent Technology Co., Ltd.

The competition is composed of theoretical knowledge and operational skills, and the contestants are deeply examined in terms of construction safety regulations, industry standards and specifications, safety production systems, practical operation skills, etc.

■ Intelligent technology accelerates the construction of tower cranes, and the tradition is greatly innovated

What is different from the past is that in this competition, the physical work of the players is lighter, but the equipment "thinks" more.

In the past, it took 2 minutes for a 20-meter tower crane to climb manually, but now it only takes 1 minute to go up the tower, and the efficiency is increased by 1 time, saving time and effort. At the same time, the auxiliary device has dual anti-fall protection for the body and personnel, which can ensure the safety of operators to the greatest extent.

The application of this new device reflects a new idea of innovation in the field of tower crane operation, and brings a revolutionary experience to improve the safety operation of tower cranes.

In addition to the ease of climbing the tower, the ease of operation has also become a new feeling for the players. Sany H series tower crane is equipped with intelligent technologies such as calibration-free, on-load speed, rotary ABS, anti-collision, etc., and the industry's first stepless frequency conversion operating handle is used for rotation, which is accurate, fast and stable. It not only effectively reduces the difficulty of operation, but also improves the operation efficiency of the construction site. Contestant Qin Renbing said: "The first time I drove a Sany tower crane, the reaction was too fast, which is 100 times more sensitive than the tower crane I usually drive." ”

■ Digitalization has helped the industry enter a new era of safe construction

At the competition site, the large screen clearly presented the operation status, operation data and on-site pictures of the players. With the application of the Internet of Things in vertical industries, construction machinery and equipment are becoming more and more intelligent, which has changed the traditional management mode of the industry, and the driver's operation and habits are recorded and analyzed, which also puts forward higher requirements for the driver's technical level and safety awareness.

▲ Large data screen

▲ 5G remote control experience

The application of digitalization, visualization and big data provides scientific support for construction site management and the improvement of tower crane drivers' capabilities.

Cai Zhengqian, a player from Yancheng, Jiangsu Province, said: "With so many peers from all over the province competing on the same stage, the competition is too tense. I was afraid that my hands would tremble when I hung it, but this tower crane was very 'smart' and very steady, which helped me."

Yin Chenbo, the chief referee of the competition, professor and doctoral supervisor of Nanjing University of Technology, introduced: "At present, the construction industry is mostly hoisting prefabricated parts, and the requirements for accuracy are getting higher and higher. Even an error of 1 to 2 centimeters in ordinary work will have a great impact on the assembly of prefabricated floor slabs and other components. ”

"The purpose of this competition is to provide a platform for technical exchanges and exposure to new products and technologies for construction hoisting operators, so as to achieve the 'double improvement' of safety awareness and operation skills. At the same time, it is also a centralized review of the spiritual outlook and technical level of tower crane drivers in Jiangsu Province, and carries forward the glorious labor and valuable skills of the times and the craftsman spirit of excellence. ”
