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:Which one is right? Are there two different kinds? This bird is confusing me.
- Whooping Crane is the name for the tallest bird in north america. A whopping crane is just a big-*** crane.
- Q:What prior education and skills are needed to become a Crane operator ?
- A basic education is required, no need for major courses. Skills however is developed through training. One is communication skills using a radio. Because crane operators have a partner called rigger, who overlooks the movement of crane below while telling instruction to the crane operator. Another skill is synchronization. Crane operators should possessed good movement synchronization and operation of levers and buttons inside his cabin. Another is good eyesight. Lastly, safety skill. Operators should know the capacity or the equipment he is operating and the calibration of the machine he is using.

- Q:Why is there as much evidence of Icabod Crane, as there is of god??
- Ichabod wasn't headless until Chuck Norris roundhouse kicked him.
- Q:Is their a difference between a flamingos and cranes birds?
- Yes quite some difference,Flamingos are crustacean feeders brine shrimp and similar, feeding by sifting water through their bills by a pumping action and feed in water.Their habitat is Tropical climbs Cranes on the other hand are mainly land or swamp birds feeding on Frogs Lizards even snakes and other insects., they live in various regions even in cold areas. This is only a brief description so I hope it has helped

- Q:Operation points of tower crane (tower crane)?
- Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
- Q:How should I go about stringing paper Cranes together??I alreadly know how to make them, its just that I have no clue how to put them together
- Depends how you want to string them... but use thread and a needle. If you want to string them vertically, put the needle through the body of the paper crane... I not sure about horizontally. Too keep them in place, place knots below the body of the crane. I hope this helps, but I hope another more experienced person answers this :P
- Q:I was wondering if anyone knows what period this book is set in? I know that it's set in the slums of New York and the story was published in 1893. But what time period does the story actually take place?
- hah ha i'm in your class too :) This project sucks... and I still haven't done it! I have to tonight..
