Tower crane 5610 why is it called QTZ63?
Q is reusable, T is tower, Z is jack up, and combined is jack up tower crane. (this is the earliest known China, now the various manufacturers have their own name, some close to the French take, such as F0/23B, the tower jib 50 meters, a maximum weight of 10 tons, 2.3 tons of weight lifting arm tip)80 is the moment, the unit is t * m, (should say is the force multiplied by distance, 800kn.m) for 5613 cranes, the maximum lifting capacity of 8 tons, the boom length is 56 meters, arm tip lifting weight 1.3 tons, maximum weight in the range of 2.5 meters ---13 meters, calculation of 8 * 13=104, so the name is QTZ104, now the provisions should be a QTZ104, but before, people think is 8 tons of weight, so called QTZ80, is now available.
Strictly speaking, 5610 should be called TC5610;At present in the domestic type mark in two ways: one is QTZ++, one is TC++, for example, such as QTZ80, Q is the first letter of Chinese "play", T is the first letter of Chinese "tower", Z is the Chinese "from" the first letter is self lifting tower crane 80, the unit is 80 tons of tons of rice, rice is a concept called lifting torque, rated torque, maximum rated product weight and maximum range; as in the 13.4 meters lift 6 tons, the product is 80 tons of rice;Such as: TC6010, T is the English TOWER, C English CRANE, TC tower crane is English shorthand, the 60 refers to the jib 60 meters long, 10 refers to the boom in the front 60 meters lift 1 tons, and TC5513 refers to the boom length of 55 meters, the front suspension of 1.3 tons.

QTZ refers to the lifting tower crane, and the 63 is the torque, the unit is tons x meters, generally in accordance with the crane's nominal gravity moment to sub model, which level is close to which model. The latter four numbers, the first two represent larger, the unit is M, and the latter two represent the largest range of maximum lifting weight, the unit is KN
