1. Brief Introduction
QTZ160 Tower Crane is a new type of large tower crane for construction developed through adopting technology by Shandong Huaxia Group in 2000. During designing, general operations like limited meta count of steel structure parts, parameter optimization of entire crane, stability check of entire crane and choice of each mechanism, etc. are completed with computerized tower crane design platform, which has reached international leading level.
Max. hoisting moment of QTZ160 (6516) Tower Crane is 1940kn/m, and each index of performance occupies leading position among domestic products of the same grade. Its advantages are as follows:
Hoisting arm can reach 65m, which largely increases covering area, and its working scope can satisfy constructions of more than two buildings simultaneously.
It has many working modes with largest application range.
Groundwork is poured on the ground without under frame, and tower crane is fixed directly on the groundwork. This method makes tower crane spare groundwork section and crossing girder, and separate working height of tower crane is 46.2m under such condition.
If construction object is high, tower crane can adopt attaching mode, and hoisting height can reach 161-200m. If it is required to be higher under special conditions, please contact our company.
No matter which kind of mode is adopted, hoisting arm has lengths of 55m, 60m and 65m, which can be chosen according to different objects.
It adopts hydraulic hoisting system to increase or reduce standard sections, which makes height of tower crane rise or fall according to height of construction to adapt construction of different buildings.
Working speed is high, timing performance is good, and working efficiency is high.
Hoisting mechanism adopts double speed double pulley winding motor to realize low speed on heavy load and high speed on light load, and max. speed can reach 100m/minute. Start and brake are steady, impact is small, and operation is convenient. Swing mechanism adopts domestically advanced frequency conversion timing project, which makes start and brake become steady and reliable.
Horizontal Arm Frame and Trolley Radius
The tower crane adopts horizontal arm frame, load is hung in hoisting trolley, and radius is realized through horizontal movement of trolley on arm frame. Compared with luffing jib tower crane, working is steady, installation is convenient, and radius application is wide, which can make hoisting performance be fully exerted, enlarge storing range of construction materials, and make disposal of general construction ichnography be convenient.
Safety devices are complete, and there are brakes fixed in each mechanism, which can ensure working safety. There are safety protecting devices like hoisting height restrictor, trolley radius restrictor, moment restrictor, hoisting weight restrictor and swing restrictor, etc. fixed in tower crane.
Driving room is set separately on side with good field of vision and large working space, which create better working environment for operator.
Operation is convenient, and maintaining is simple.
Electric control system adopts domestically advanced PLC control with automatic malfunction judgment, overload and over moment safety chain protection, motor overtime protection, program controller of famous Japan Mitsubishi Company, transducer of Japan Yaskawa Company, relay of OMR Company and contactors manufactured through introducing technology of TE Company, which makes its reliability be much higher than general electric control systems. It is safe and reliable with less malfunctions.
There is no central collector to avoid disadvantages of short circuit and creepage because of damp and make entrance and exit of driver be easy.

- Q:I have recently mounted a Meiller MK 40 R / 2 crane on my truck and I wonder if my truck's hydraulic pump can support it without problems. I have a Mercedes-Benz 813 truck of 1987 and the crane is more or less the same years by the way. Should I change my truck's pump?

- Q:I don't like the cranes that use a wired pulley systems for controlling the camera.The crane will need to carry a 7 pound camcorder.
- Camera okorder /
- Q:Does anyone know of any companies that sell mobile cranes suited for extreme cold? I'm aware of Liebherr and Havator's harbor cranes, but I can't find much else.Thanks
- this is not my area of study but i will give you something to consider. if you are looking for a large capacity crane for use on permafrost, you wont find one. the pressure placed on the permafrost by large weights will cause it to melt. anything that is heavy, like a house, will sink in the tundra just like it will in a swamp. for houses they excavate the foundation a build a giant wooden raft that the hose floats on. in ST Petersburg, Russians preferred a mix of reeds and slave laborers corpses's to build the raft. as long as the ground is not frozen there is somebody how makes what you want. if the ground is frozen, you will only find small machinery. best of luck ps dont look to hard. lots of diesel engines work great at sub-subfreezing temps.
- Q:Can the attached arm of the tower crane be welded?
- The attached arm of a tower crane can not be welded and can only be bolted.Adhesion calculation of tower craneTower crane attachment (anchor) device structure, internal force and installation requirements in the use of narrative instructions so in the tower crane installation and use, the use of units can be executed according to the requirements, do not need to calculate, only when the tower crane installation position to the building from the over manual provisions, to increase attached rod (Zhi Chenggan) two, spacing or attached rod connected with a building when changing to attached calculation.
- Q:I know that an ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane, such as long life or recovery from illness or injury. This summation, or something like it comes up in every search I do for the legend. Is there a full story that goes with the original legend? If so I would very much like to read it. Wikipedia doesn't have it. Also, while Sadako's story is very touching, it is not the one I'm looking for.
- Well, I read that cranes are symbolic because they are thought as legendary creatures who can live to 1000 years. They apparently have a lot of faith, for they mate only once in that time, and patience. So, that's why it's said that if one can fold 1,000 cranes, 1 crane for 1 year a crane lives, then they will be granted a wish, because they have shown great perseverance and faith in order to stay till the end to fold a thousand cranes. Not sure if this is what you're looking for, but I saw this online while searching up the symbolism of origami cranes. And I know that I am late by 6 years.
- Q:I already have 864 cranes and I wanna know what kind of wishes can I make? And are there consequences?Can I wish something like my mom won the lottery and we become rich? (Just an example!)And can you wish for death? (Just a question!)
- You can make whatever wishes you want. Just remember that the wishes you make reflects what kind of person you are. So maybe you should make wishes you can be proud of. Also remember, if wishes were horses beggars would ride If you for example would wish that you would have $10, your wish is most likely to be fulfilled if you manage to sell each origami crane for 1 cent... Generally wishes come true if you really work for them, Not by sitting, doing nothing and wishing.
- Q:What is the free height of a tower crane?
- General small 40 tower, its free height is about 30 meters. The 63-80 tower is usually about 45 meters. The 125 tower is about 47-50 meters.
- Q:the lifting capacity of a hydraulic crane is based on two primary design factors what are they?
- Stability(when it tips) and mechanical structure (when it breaks). Bomba is right: when it comes to a simple hydraulic cylinder. The complete crane is a more complex beast than that though.
- Q:Any difference?
- The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.
- Q:im really curious about the 1000 paper crane legend. i went on many different websites to learn about it. one said that you are supposed to have 25 strings to hold the paper cranes (40 each) on it and is that true? also a lot websites said that they used them for weddings so do you have to use them for weddings? or can it be any wish you want? i have a few more questions about it but i will ask whoever seems to know the most about it. thank you:)
- Most people give paper cranes to their love ones who are ill. Since it is a tedious job, they will all help each other in folding it. Shalbi I may be wrong, but I know that to be able to make a wish, you have to fold the cranes yourself. The wish can be anything, but the most common wish is to recover from sickness and have a prosperous life. A crane signifies longevity and fidelity that is why they like to use them on weddings. ^_^
