QTZ300A(TC7030A) tower crane is a fixed, self-elevating, and attached tower crane. In addition to its optimized parameters, reliable performance, well-looking appearance, and excellent quality, its advantages include long boom, larger working coverage, hydraulic rising, and tandem mounted tower body. the beautity of the design is made up by its easy operating, good applicability, high maintenability, and low price-value ratio, as well as meeting the requirements from construction units at different levels. Its maximum lifting height is greatly increased by its self-elevating and attached design. It is capable to meet the construction requirement of all kinds of industrial, commercial, office, and civil buildings lower than 141 meters, and thus is an ideal tower crane machine in civil construction industry.

Main features of QTZ300A(TC7030A) tower crane

(1)The rated lifting moment of QTZ300A(TC7030A) tower crane is 300 t.m. The max working range is 70m. Max working range lifting weight is 3.0t. Large coverage improves transport efficiency.

(2)The standard section of the tower body is a sheet-mounted structure, and sheets are bolted together. This way brings convenience to disassembling and assembling, transporting, stacking, and storing.

(3)QTZ300A(TC7030A) tower crane is equipped a set of hydraulic rising mechanism, which may not only smoothly lift-up, but also accurately and reliably position.

(4)The hoisting mechanism is a dual-motor system, provides slow moving in function. It offers smooth starting and accurate positioning, besides, its high speed gear is able to give fast working speed with high working efficiency. 

(5)The wide and brilliant operator cab brings widen field of vision, convenient and comfortable operation.

(6)The fail-safe device not only is complete, and high accuracy, but also works reliably, can be adjusted in a simple and convenient way.


Q: which crane makes only one Life Partner ?
Apparently, although traditionally, most cranes were thought to mate for life, recent research suggests that they do actually change partners during their lives. I don't know how extensive or how conclusive the research is, or what species it involved, but it does suggest that the folktale may not be true.
Q: Which kind is better, gantry crane or tower crane?
Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.
Q: analysis of jib crane?
I would suggest that you delete this question and submit a new question with enough details for someone to give you an answer. This is not a question I can give you much help on
Q: Only two magnification and four magnification are seen in the data, and the difference in weight is 0.1T. 10How does this magnification change during construction? Do you know that the door crane is changing the grab tower?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q: How good a job do you think Crane did in voicing the theme of pride/morales in Red Badge of Courage?
How good a job do _you_ think he did? If this is a homework then your teacher wants _your_ opinion, not that of a stranger on the internet.
Q: was he a realist or naturalist
Stephen Crane was a naturalist a lot like Jack London. His main themes were man vs. nature and man vs. himself in which nature is an abstract, omnipotent force that does not (and really cannot) care what becomes of the individual. In Crane's writings, man is often faced with strengths and weaknesses within himself when confronted by extremes of uncaring Nature (see the short story The Open Boat).

Q: I've been wondering and haven't been able to find any information on it. Where does the sky crane go after it drops off Curiosity? You see it fly off in all of the videos, but no information is given on where it goes? Does anyone know?
It was programmed to fly off to the side well away from Curiosity's landing spot, and then crash. NASA doesn't like to say much about it, because it dumped a mess of nuclear fuel! One of the 2004 rovers actually travelled to where its heat shield fell, and was able to photograph it.
Q: What are the climbing claws on the tower crane?
Climbing is lifting work cylinder claw pole on the standard main limb rod bearing points of the.
Q: What are the safety devices in a tower crane?
1 torque limiter. There are two kinds of mechanical electronic.2 weight limiter. There are two kinds of mechanical and electronic.3, lifting limit device.4, slewing limit device.5, amplitude limiter.6, car anti break shaft device.7, the car anti broken rope device.8, jacking up anti stripping device.9, the collision lights.10, luffing tower crane luffing speed protection.11, walking crane limit limiter.12, all kinds of warning signs.
