Main Features of Tower Crane
1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.
2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

- Q: Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
- 6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
- Q: please tell me thats not what i think it is O_O
- It probably is what you think. I've heard that they use whale parts to make some brands of lipstick so I wouldn't be surprised if they used parts of other animals in cosmetics. =X
- Q: All types of jack up cranes. How is the maximum lifting torque converted?
- Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
- Q: Is it to do with visibility?What are some other colours of cranes?
- I think Red Oxide, protects best from corrosion, and red colour also warns about danger. We can see yellow colour also.
- 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: why do siberian crane migrate in india?
- The Siberian Cranes nest in western Siberia . During Winter season in Siberia , they migrate to India which is their wintering ground.The migration route stretches for 4000 miles. Their resting place at the time of migration is the Lake Ab-i-Estada in Afghanistan. The Kaladeo Ghana National Park or the Bharatpur National Park has been declared a world heritage site because the Siberian Crane traverses nearly half of the globe to reach it. The Siberian Crane is presently an endangered species. Larger numbers of birds have been hunted down over the years especially when they undertake the perilous journeys across the Himalayas to reach the wet land. They are shot down in Pakistan to be gifted to friends and relatives. This has led to a severe decline in the number of Siberian Cranes in the world. The immediate need of the hour is to provide safety to the Siberian cranes along their migration route. This popular visitor has not been seen in the last two years in India. The last pair of Siberian Cranes which had made the Bharatpur Bird Sanctuary their seasonal home in the year 2002 was not seen in the year 2003. Their absence is indeed painful and one of the aims of the Crane foundation is to bring back the Siberian Crane to India.

- Measure a crane hook then draw it. Even better, visit a manufacturer's web site and see if you can download one of their drawings for a hook.
- Q: Is the working load of a crane the maximum weight it is able to lift?
- its very less than the actual breaking point just to be on the safe side.
- Q: What is the safe distance of a tower crane to the surrounding buildings?
- It's 5 meters up and down. Outside the radius of rotation is 3 meters, such as QTZ5010, tower crane rotating radius type, 50 meters in diameter, one hundred meters outside the scope is safe
- Q: What is the Tower crane Roadb track laying criteria?????????
- The okorder ) track in the vertical and horizontal direction is not more than 1 / 1000. (we Should use the standard instrument, two tracks, and keep in10m range ,Measuring not less than 3 periods, respectively,taking the average).
