FAQ
Q1:What is the Warranty for tower cranes?
A1:For the tower cranes,we have 1 years warranty.If any quality problems on our side occured in this period ,we will supply the free new one for replacement.
Q2:What is the mean of QTZ and TC for tower crane model?And please illustrate.
A2:QTZ is classified according to China National Standard.
"Q" is the acronym of Crane in Chinese language(Qing Zhongji), "T" is the acronym of Tower head type in Chinese language(Ta Shi) and "Z" is the acronym of self rising in Chinese language(Zi Sheng Shi)
"TC" is the acronym of Tower Crane in English language.
For example:QTZ63(5013) means topkit tower crane, the rated lifting moment is 630KN.M (63 is 10-1 of the rated lifting moment).The working jib length is 50 meter and tip load is 1.3t when jib length is 50m.
