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: the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
- difficult question
- Q: ...the crate weighs 4000N when resting on the ground. Find the followinga)The tension in the cable necessary to do thisb)The work done by the cablec)The work done by gravityd)The total work done by the systeme)The final velocity of the crate
- One-fifth of a g is 1.96 m/s?. The mass of the crate is... m = F / a = 4,000 N / 9.8 m/s? = 408 kg The force of the crane must be greater than that of the force of gravity. The acceleration must therefore greater as well. 9.8 m/s? + 1.96 m/s? = 11.8 m/s? a) T = ma = 408 kg x 11.8 m/s? = 4.81 x 10^3 N b) W = Fd = (4.81 x 10^3 N) x 25.0 m = 1.20 x 10^5 J c) W = Fd = 4,000 N x 25.0 m = 1.00 x 10^5 J d) W (total) = W (crane) + W (gravity) = (1.20 x 10^5 J) + (1.00 x 10^5 J) = 2.20 x 10^5 J e) v (final) = (v? + 2a?x)^(1/2) = ((0 m/s)? + (2 x 1.96 m/s? x 25.0 m))^(1/2) = 9.90 m/s I'm sure that all of my answers are correct. If anything is incorrect, please e-mail me again. Best of luck to you Jim.
- Q: Recently, it seems that any time my front door is open for any period of time, crane flies start migrating inside. I would like to find a way to keep them out when the door is open. Are crane flies attracted to electric bug zappers?
- It is much easier to eliminate the reason crane flies occur around your house. They occur in moist areas with decaying vegetation. Unless you live in a swamp you should let the soils around your house dry out. You can also spray the area around your door with an insecticide to keep them from gathering there.
- Q: Like those huge cranes on the top of buildings that are being constructed - how do they get them up there???
- depends on the situation some times they use another crane. some times it is hydralic lifts. they just keep adding sections to the superstructure from the bottom. as they go up they enclose the crane superstructure in side the envelope of the building and add sections of super structure as needed to change the height. then they bolt it back to the building
- Q: What is the easiest way to transport vertically? What is applicable?What is the difference between tower crane and tower crane?
- Tower crane, tower crane, also known as tower craneTower crane = tower crane = tower craneThere are many ways of vertical transportation. Construction elevator hoist etc..Tower crane features: large operating space, mainly used in housing construction materials vertical and horizontal transmission and installation of building components.It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
- Q: What kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
- It must be installed:To prevent the trolley cable broken car slip away;
- Q: Has anyone ever folded 1000 paper cranes? If so did your wish come true? If it did come true what did you wish for? :) Thanks so much!
- Yes i have. For a college friends wedding. The groom makes at least one crane. She was from Hawaii and it's one of the Philippine traditions. There's a story that goes along with it. In Hi there are companies that will take the flat cranes and form them into another design. like a vase or something that can be framed. I think her wish was just to get them finished within 1 week before the wedding... ;) We DID! That was luck in itself. not sure if her real wish came true.
- Q: Is the crane a metaphor for the woman? Or does it transform into one? OR does the guy marry a bird? I've been listening to this all week and cannot discern which is right...maybe that was Colin's intention? A little help here?
- It's a story about a peasant living in, I assume, rural Japan, it being a Japanese folk tale. He finds a wounded crane on the road as he's walking one night. It has an arrow in its wing, and he pulls out the arrow and revives the crane. A couple of days later this mysterious woman shows up at his door and he brings her in. Eventually, they fall in love and are married. Although they're poor-- she's a seamstress, a weaver-- she suggests that she can make this cloth that he could sell and make money. But the one condition is that when she's weaving he can't look into the room at her weaving. This goes on for awhile, until eventually the peasant's curiosity gets the best of him and he looks in. It turns out that the woman is a crane, and she's pulling feathers from her wings and putting them into the cloth, which is what makes it so beautiful and soft. Apparently, having looked in at her breaks the spell and she turns permanently back into a crane and flies away.
- Q: What are the impacts of construction cranes on the human society?
- construction cranes enabled the building of multiple story buildings which fostered urbanism. It changed the village oriented way of life in America, for good and bad. We became more boadly oriented in our business ventures which increased the stanting of the U.S. in world affairs, but it decreased the degree of brotherhood people felt for each other as they left their roots and dwelt amongst relative strangers.
- Q: Hi there!I was planning on making an electromagnetic crane, and I already understand how the electromagnet works. Its for the science fair in two weeks, but they asked us to make our projects soon.But I not sure hot to build the crane itself, any ideas?
- Here are literally thousands of organized woodworking projects in a members area and all you have to do is get them off your computer any time you want.
