ZOOMLION T7020-10 all round PC working condition tower crane advanced technology, excellent quality
In recent years, PC (precast concrete precast concrete) project with the advantages of low labor cost, high construction efficiency, environmental protection level higher, more and more attention by the government departments.
At the end of 2015, the Ministry of housing issued a notice, request to PC national building new buildings in 2025 accounted for more than 50% proportion, 5 years is expected to add 8 billion 150 million square meters of housing market demand, which will have 3 billion 90 million square meters of building is PC, equivalent to about 100 thousand buildings, the prospects for the future development of the PC project will be limited.
Optimization of T7020 device structure, convenient assembling and disassembling, assembling control precision, low error rate, effectively solves the key problems of PC project construction, adapts to the requirement of the PC project, PC is the best in the industry at present condition of tower crane.
T7020 flat head tower crane adopts the German JOST flat head technology, the integration of Chinese and foreign advanced technology, high quality, excellent performance, first-class technology.
In 2011, ZOOMLION bought JOST flat head tower crane technology. Through the past two years of cooperation, ZOOMLION integrated the European flat head tower design technology and philosophy, developed a series of high-end flat end tower products such as T7020. JOST series of models have successfully passed the EU CE, Singapore MOM security certification, successfully entered the European and American markets.
Equipment management is more convenient
T7020 through the cancellation of the traditional rotary tower structure, greatly reduce the number of parts, so that the balance arm can directly with the support and jib connection, greatly saves the assembly time, more conducive to the user equipment management.
Quick assembly and high efficiency installation
The balance arm, T7020 tower crane jib, an installation platform and cab mounting platform adopts fast joint. Compared with the traditional joint, the quick mounting joint is more efficient, time-saving and labor-saving.
Lifting performance is excellent, arm length combination is rich
The maximum gravity moment of T7020 reaches 278t.m, and the lifting weight of jib can reach 2.0T, which can provide 9 kinds of arm length combinations.
Optimum PC working condition tower crane
40m can load 6T, arm tip can load 2T, can fully cover the current PC hoisting conditions need. The precise position adjustment function has obvious advantages in the PC working condition with low error margin requirement.
The more significant advantage of tower operation
Hoisting wire rope drop was reduced by 35%, no tower design, strong anti-jamming, more conducive to the tower operation. The increase of hook weight is also beneficial to improve the rope lifting effect and improve the service life of wire rope.
Variable frequency control, small impact force
The lifting structure and luffing mechanism adopt frequency conversion control, which has good speed regulating performance, stable lifting and braking, small impact force.
Precise control and convenient switching
It can be equipped with micro switch, fast and fast combination, fast position, fine adjustment, the control accuracy can reach millimeter level.
Quick turning position and strong wind resistance
The slewing mechanism adopts ZRCV control technology developed by ZOOMLION, which has strong anti wind performance and can be used in anti car and fast position.
In terms of intelligent upgrade, T7020 real-time control is within reach. Optional TSM system, intelligent management equipment, troubleshooting simple. Through the application of sensor technology, Internet and networking technology, using mobile phone APP push maintenance reminders, fault alarm, achieve three-dimensional monitoring equipment operators, allowing users to get a key equipment of the basic information, master the use condition whenever and wherever possible.
