Product Description:

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:what is the 1000 paper crane legend and is it true?
I am not sure if it is true, but There is a myth that if a sick person makes 1000 paper cranes they will get one wish from god. Read the story Sadako and the thousand paper cranes.
Q:Is there a world record for making paper cranes?
Yes! To commemorate the fiftieth anniversary of the dropping of the atom bomb on Hiroshima, two hundred thousand folded paper cranes were completed by December 15th 1995. Each crane had someone's name and peace message written on it. The intention is to preserve them to hand on to the 21st century. The event was sponsored by the Hiroshima International Cultural Foundation. There are other cool facts at the website below like the world's largest paper crane, most cranes in one hour, etc.
Q:please advise which type of air condition is powerful for electric crane on ship ,?
I would use a roof mounted unit. They are commonly used in campers. 10,000 btu should be ample.

Q:What happens to the sky crane after it drops off the Curiosity rover?
It flies off a safe distance from Curiosity and then is allowed to crash. It's done its job and there's no reason to keep it around.
Q:The arm of a crane at a construction site is 17.0 m long, and it makes an angle of 13.5◦ with the horizantal.?
The easy answer is that the applied torque is the cross product of the radial arm and the force, or in this case T = 811*17*cos(13.5). The hard (it's actually not that hard) answer will depend on the design and material properties of the crane. Since the problem asks for max torque, I'd find the bending stress due to the moment found above (T = 811*17*cos(13.5)) where bending stress = Ty/I. Next, compare this to the yield stress of the crane's material and an appropriate failure criterion.
Q:Origami crane word problem?
1/5 + 1/x = 1/3 == x = 15/2 = 7.5 h answer : 7.5 hours ++++++++++++++++++++
Q:Are steam cranes still used to clear train derailments?
No, they don't. They have to use road cranes - think of the accident at Grayrigg some while back. They had terrible trouble clearing the line as heavy lifting equipment had to be brought quite a distance over muddy fields. I seem to remember special temporary roads had to be laid. Similarly with the freight accident in Scotland a few weeks back, roads were closed, again whilst wreckage was cleared.
