1. Brief Introduction
The QTK25 model self erection tower crane is developed by our company on basis of years of
experiences in production and new technical innovation.
This tower crane is whole consignment & fast set-up vertical and level transport machinery. Mainly apply
to 7~10 storey civil buildings. This machine also could used in factory, goods yard, station, ports to move
products, as well as to be a mobile hoisting machine

4 FAQ of QTK25 model self erection tower crane
What about the security electricity control system?
1)Hoisting system is controlled by double-feedback system. The speed signal transmits back to FI and PLC to ensure the hoisting security.
2) All the connections are used high-current plugs with signals to avoid mispluging.
3) The slewing control modules are developed by LINDE COMASA (Spain) and could avoid the driver from danger in case of misoperation.
4) The tower crane is with real-time display safety monitoring device which records the real time data of the tower crane, and the device could be tel-controlld and bring black box function into play. The electrical design of CJ series tower cranes accords with the CE standards.
- Q:How does a crane get down from a skyscraper once they're done using it? Like the crane on top of the skyscraper, do they get take it apart?
- realdolby is correct. Small crane from parts that can be transported in service elevator is brought up and assembled. It is used to swing out and lower larger crane's parts. Then the small crane is broken apart and taken down in elevator.
- Q:some people call it a crane, others say claw but the point is...where can i get one? i dont want a huge one, and i dont want a small one. A medium size one. the shops have to get them from somewhere right? oh, and i'd rather not get one from Ebay. is there a business or something? thank you!

- Q:What are the characteristics of a tower crane?
- Four, according to the different installation methods of cranes, can be divided into folding transport, self erection of the rapid erection of tower cranes and the need to use the auxiliary machine assembly and disassembly of tower cranes.Can set up their own fast loading crane are small and medium slewing tower crane, mainly used for short duration, low buildings move frequently, the main advantage is to improve work efficiency, save installation cost, save time and labor and material, disadvantage is the complicated structure, large amount of maintenance.A tower crane that needs to be disassembled and assembled by an auxiliary machine is mainly used in middle and high rise buildings, with large working range and large lifting capacity. It is the main type of construction site at present.Five, according to whether the spire structure, can be divided into flat head tower crane and tower tower crane.Tower crane is a new type of tower crane is developed in recent years, its characteristic is the tower cap and the rod part before and after the cancellation in the structure of the original tower crane on the enhanced structural strength of the arm and balance arm, arm and balance arm is directly connected, the utility model has the advantages of:1 、 the whole machine is small in size, easy to install and safe, reduce transportation and storage costs;2, the boom of tolerance and good performance, uniform stress, small damage on the structure and connection part;3, component design can be standardized, modular and interchangeable, reduce equipment idle, improve investment efficiency.It is in the same type of tower crane tower crane head Zhongping slightly higher prices.
- Q:HSE Officers can better answer this question or a qualified Crane operator it self can explain.
- each crane is so different. it depends on the rated crane load, the lifted distance from the crane and actuall load to be lifted. Each crane an envelope of angles to the horizontal, lifted load, and distance from the crane. The crane operator must insure that he is within this envelope or the crane may topple over. Also, the wind at the time of the lift must be considered. If you can picture a seesaw with loads pivoting about a fulcrum. When two people are on the seesaw, one person is the crane and the other is the load to be lifted. Only in the case of a crane, the fulcrum is at the crane itself with a large dead load counter weight behind the cab operator.
- Q:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
- High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
- Q:well I am making 1000 paper cranes... I am on 18... but how do you string them all together anyone know?
- There should be a tiny hole at the bottom. Thread some colorful embroidery floss onto a needle, poke the needle through the hole in the bottom and straight up through the point at the top (on the crane's back). You can string one after another like this. You'll have to just take a guess on the length of the thread that you'll need, and be sure to knot it on the end. I have dozens of strings that I've made and given to friends like this. If you like, you can separate each crane by a colorful glass bead. It looks really cheerful.
- Q:What is the present status of large Boom Tower Crane?
- Large boom crane arm depicts one and another new history. New York's World Trade Center towers is the skyscraper that is the highest and has the most floor in New York City .Its main building is steel and concrete composite structures,using steel 78 thousand tons.The Building started in 1966 and lasted seven years, with 110 layers, 411 meter in height as a giant skyscraper it is writed in history. During in Construction
- Q:Secured to a concrete floor with 12 30mm bolts
- That can only be answered by analizing it. A crane as you are supposed to know has different loads and directions of impact due to the moving bridge, the trolley, and break loads. So what it can lift depend on the whole structure. Besides depends as much on the type of crane
- 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:do they get the concrete blocks up that hang at the end? Do they use another type of crane to assemble them?
- Yep, they use a smaller crane that sits on the back of a truck and has a telescopic arm, it only takes a few days. There's a lot of construction going on in my city and I've seen them do it.
