Tower crane model
There are many ways to compile the model of tower crane. In the past, China has made unified regulations on this. Although this regulation is still being implemented, many tower crane manufacturers still have a set of opinions. There are two main parameters in the model expression of tower crane: one is the rated lifting torque, and the other is the maximum arm length and arm end weight. Here are several typical compilation methods, and three common classification methods are as follows:
1, standard numbering method
According to ZBJO4008, the model composition of tower crane in China is: class group code+form+feature code+main parameter code.
Class: Q—— (from)
Group: t- (tower)
Type: upward rotating jack-up Z- (from)
Fixed g- (solid)
Internal climbing p- (climbing)
Next round of jacking speed (liter)
The main parameter is the nominal lifting torque.
Examples of labels are as follows:
Fixed tower crane with rated lifting capacity of 600kNm: QTG600
Nominal lifting torque 1000kNm jack-up tower crane: QTZ 1000.
Some tower cranes still use tm as the measuring unit of crane torque, so the above three tower crane models are expressed as QTG60 and QTZ 100 respectively.
2, enterprise characteristic number way
(TowerCrane)TC replaces the class group code, omits the formal feature code, and replaces the main parameter code with two basic parameter codes: maximum amplitude (M) and maximum amplitude lifting weight (kN).
3. Technical numbering method
A the first letter of the tower crane model is the maximum arm length code, which means:
F-50 meters
H-60 meters
K-70 meters
Meters-80 meters
B the second character of the tower crane model is the code of the maximum lifting weight of a single rope, which means:
0——2t
3——3t
C. When the third character of the tower crane model is the maximum amplitude, the maximum lifting value of the double rope, in kN.
D the fourth character of the tower crane model is the code name of the improved design. ?
