The Zhongtian 6513-8 tower crane produced in 2020 has many significant selling points. In terms of application scenarios, it can be called a classic model of small and medium-sized tower cranes. It has a small body, great strength, and super applicability. Whether it is civil construction, industrial and mining, bridges, or sports venues, etc., it can be easily controlled, and can play a key role in various construction sites. In terms of safety performance, advanced technology and design are adopted. The tower body standard section connection is de-bolted, the installation size is universal, and the traditional chip standard section is integrated, which greatly solves the potential safety hazards that may be brought about by the previous bolt-type standard section in construction, effectively ensuring construction safety. At the same time, it is also equipped with an intelligent control system to monitor the operation status of the tower crane in real time. If there is an abnormality, it can be warned in time to escort the safety of the entire construction process. In terms of operation experience, the three major institutions all use full frequency conversion control, which is very silky and responsive, and can accurately control the lifting operation. The integrated cab design provides a comfortable driving environment for the driver, reduces work fatigue, and the driver is more handy and efficient. In addition, the lifting arm connection adopts quick disassembly and assembly joints, which are simple, easy, fast, and time-saving to install and disassemble. During installation and disassembly, it can greatly reduce the requirements for the lifting capacity of the required truck crane, and also save the cost of disassembly and assembly. It is especially suitable for tower crane disassembly and assembly and group tower cross-operation under limited conditions at the construction site.
