You can operate a tower crane without going to high altitudes! How can a 5G smart tower crane be "unmanned"?
How are tower cranes classified?
Tower cranes are referred to as "tower cranes" because of their tower-like appearance. They are mainly used in industrial and civil construction, ports, shipbuilding and other projects with large lifting heights and large working radius.
5G tower crane remote control hoisting efficiency increased by 15%
At the construction site of Jinan Metro Line 7, the first subway line across the Yellow River in the country, staff demonstrated the digital construction platform of the project's innovative application. The platform can optimize the construction configuration and schedule through intelligent algorithms, and realize dynamic adjustment of progress and real-time early warning.
Main technical parameters of tower crane
The main technical parameters of tower cranes include maximum lifting capacity, end lifting load (lifting torque), maximum/minimum amplitude, maximum lifting height, structural type, amplitude change method, tower cross-sectional dimensions, etc.
About the development process of tower cranes in China
In the early 1950s, China's tower cranes started from imitation. In 1954, it imitated the East German Architect I tower crane; in the 1960s, it designed and manufactured 25tm, 40tm, and 60tm models, mostly boom-type; in the 1970s, with the increase in high-rise buildings, new requirements were put forward for construction machinery, so 160tm attached, 45tm internal climbing, 120tm self-elevating tower cranes came out one after another;
Features of tower crane related equipment
The boom of a tower crane can be divided into two types: horizontal and lever. When the boom is horizontal, the load trolley moves along the horizontal boom to change the amplitude, and the amplitude change movement is balanced. The boom is longer, but the boom has a larger deadweight. When the boom is lever, the luffing mechanism pulls the boom to change the amplitude. The amplitude change movement is not as stable as the horizontal type, but its deadweight is smaller.
The History and Development of Tower Cranes
The production and application of tower cranes in my country has a history of more than 50 years, and has gone through a process from surveying and imitation to self-design and manufacturing.
Development Trend of Tower Crane Safety
The development of safety protection devices for tower cranes in my country began in the late 1950s, and has mainly gone through mechanical, electronic simulation, digital and microcomputer control forms. Due to the late start, the technical level is relatively low. In the early days, it was mainly focused on safety devices such as lifting weight overload limiters, torque limiters, amplitude and height limiters, and could only monitor the data of tower crane operation.
Overview of tower cranes and their safety and management
A tower crane is a rotating crane with a boom mounted on the top of a tall tower. It has a large working range and is mainly used for vertical transportation of materials and component installation in multi-story and high-rise building construction.
