Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
As for the calculation method, the weight of a simple arm length * arm tip can not be used, because the nominal lifting torque of the tower crane is not calculated at the maximum amplitude.However, the maximum weight can be calculated by the maximum amplitude of the maximum weight, such as 5613 tower cranes, the maximum lifting capacity of 6 tons, while the maximum variable distance of 6 tons reached 15m, 60KN * 15m=800KN.m.The above is only my personal understanding of the tower crane, but I am not a professional construction machinery, the above calculations do not know whether it is reasonable, I hope to help you.
The type of "QTZ100" indicates the hoisting tower crane with nominal lifting torque up to 1000KN.m;5610, 5613, 6015 and so on model meaning is, the first 2 digits indicate effective variable amplitude length, the unit is m, and the latter 2 for the largest amplitude of gravity, the unit is KN.These two models do not have any objections, can be converted, not the latter way of expression is more reasonable, and by the current domestic manufacturers widely used.TC5610 nominal lifting torque to 630KN.m, but not up to 800KN.m, so it should be considered QTZ63 series.TC5613 nominal lifting torque reached 800KN.m, but not 1000KN.m, so divided into the QTZ80 series.TC6015 nominal lifting torque reaches 1000KN.m, so it is divided into QTZ100 series.
The name of QTZ is the former mechanical standard, Q refers to the crane, T refers to the tower, Z is to indicate the self lifting, and the latter figure represents the nominal torque, the unit is T.M (the standard unit is KN.m)The type of "QTZ63" indicates the hoisting tower crane with nominal lifting torque up to 630KN.m;The type of "QTZ80" indicates the hoisting tower crane with nominal lifting torque up to 800KN.m;
