QTZ50(5010A) tower crane is hoisting and conveying machinery which is designed by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 500kN•m. The tower crane has the lifting height of 30m and the adhesion lifting height of 120m (2 magnification) during independent use.
All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 25.5kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises.

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q: Is tower crane a tower crane?: Yes, the tower crane is commonly known as the "standard" in the industry. It is called tower crane.

Q: How many types of crane?: Types Of Crane

Q: What is the minimum radius of a tower crane?: Luffing jib crane luffing mechanism to control the lifting radius, which is lifting and landing boom.At the minimum radius, the boom is angled to the vertical. The higher the rise, the larger the angle, the smaller the radius.I wonder if it's this angle? Hope to be of help to you,

Q: Please help!: this would help you i hope good luck researching

Q: I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks: I would think it is run by diesel,or electric.

Q: Which style of Kung Fu has an animal system besides Shaolin? Which one has the Tiger, Monkey, Mantis, Snake, and Crane animals (not Shaolin because Shaolin has Dragon, Tiger, Leopard, Snake, and Crane.): Mantis is not a part of a style, it is a style in its own right. There are also more than one type or style of Mantis. There is Southern Mantis as well as others. There are estimated to be at least 300 to 400, and possibly more style of Kung-Fu. Man have more than one version of branch. Do not get caught up in the idea that Shaolin contains this or that as the subject is controversial at best. You mentioned Shaolin as being Dragon Leopard, Tiger, Snake and Crane. But truth is that everyone did not learn all of those styles. Many students were taught only one of them. The problem here is that people tend to assume that things are always one way, when in fact they often break all rules of assumption. Monkey is another concept or style that is often misunderstood. There is and is not such a thing as a monkey style. It is not easy to clearly explain. The few styles that are called Monkey styles are rare. There is also what ar known as drunken styles. These are not always separate styles but sometimes are taught as a version or level of other styles. Drunken Monkey is often perceived to be a set style or referring to only one specific style. It is not so. drunken monkey can refer to more than one variation of this and may also be seen as something coming form more than one unrelated style. As I have attempted to do, it is a difficult and confusing subject that is often not clear or correct as to what has been published about it. ....

Q: I looking for information on the surname Crane.?: The name Crane was first used among the Boernician people of the Scottish-English border region. It is a name for a person whose was tall, and had long legs. This nickname derived from the Old English words cranuc, and cornuc, which mean crane. Spelling variations occur frequently in Scottish names that date from the medieval era. They result from a general lack of grammatical rules and the tendency to spell names according to sound. Crane has been spelled Crane, Craine, Crain, Cran, Crann, Crayne and others. First found in Suffolk where they were seated from very early times and were granted lands by Duke William of Normandy, their liege Lord, for their distinguished assistance at the Battle of Hastings in 1066 A.D. In the 20th century, the ancestors of many of those Boernician-Scottish people still populate North America. They distributed themselves on either side of the border at the time of the War of Independence. United Empire Loyalists went north to Canada and those who wanted a new nation stayed south. Both groups went on to found great nations. Some of the first North American settlers with Crane name or one of its variants: Jasper Crane who settled in Boston Mass. in 1637; Richard Crane settled in Virginia in 1635; Samuel Crane settled in Virginia in 1653; Mary Crane settled in Virginia in 1684. Some noteworthy people of the name Crane * Harold Hart Crane, American poet * Robert Edward Crane, American disc jockey and actor, best known for his performance in the television sitcom Hogan's Heroes * Stephen Townley Crane, American novelist. * Professor Francis Crane, Law * Sir Harry Crane, * Morley Crane, Pomology * William M. Crane, eponym of USS Crane, Wickes class destroyer

Q: I know it sounds like a silly question but I just wanted to know what kind of crane he is because I've never seen a crane with black feathers.: Red-crowned Crane is a large crane and is the second rarest crane in the world. In East Asia, it is known as a symbol of luck and fidelity

Q: Just curious... I'm not in construction and always wondered...: The top sections of the mast beneath the crane are removed one at a time and lowered to the ground. The top section of the crane has hydraulic rams that lower it down one mast section at a time. It is hard to describe without a diagram or photos. See photos at attached link. In some design, the jacking portion is at ground level. The crane jacks itself up so a 20' section of the mast can be unbolted and slide out. Then the jack is lowered so the process can be repeated. See second link for photos and a more detailed explanation.

Q: in design of steel structures as per asce2005 or ibc2006 ,what load combinations are to be considered when crane loads and seismic loads are present?: Uh, depends on if you're using ASD or LRFD load cases out of ASCE 7-05. I also think IBC 2006 sometimes changes the fine print and also offers their own load cases for ASD and LRFD. A starting point (LRFD case 5 ASCE 7-05) might be 1.2D+1.0E+ L, and for ASD - case 6 - D + 0.75(0.7E) + 0.75L.
