The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for400Kn.m;the maximum hoisting load of 4t and the maximum working radius of 48m.The hoisting height of anchoring tower crane is 29.7m and that of climbing tower crane is 90m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards

- Q: a crane lifts load of 500kg mass to a distance f 20m in 10s at a constant velocity. how much work is done?
- work done(W) is given by the change in the potential energy(P.E). here, initial P.E = 0. final P.E = mgh = (500)(10)(20) = 100000 J =100 KJ (kilo joules) therefore work done = 100 KJ. here distance means vertical height.But if the crane takes the load parallel to the ground ,then work done will be zero.Time is given here to calculate the power of the crane given by work/time = 10 KW(kilo watts).
- 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: I read the book and thought of a theory... I think that the headless horseman is just and alter ego Brom Bones alter ego and he wanted to kill Brom Bones for his beloved Katrina Van Tassel... I want to hear your opinions and theories possibly involving what you think Katrina said to Ichabod during the party. That would be nice thank you.
- For the best answers, search on this site Seeing as there are no other answers so far, I thought I'd write what I know :) I've never read the legend and the film may have a different ending, but in the film Ichabod returns to New York. x
- Q: Is there a certain direction and reason a construction worker will leave a crane facing a certain direction.
- I don't think there is a particular direction unless prevailing winds are a factor. Here in Las Vegas, cranes, when idle don't seem to have a pattern. At least from what I have seen.
- Q: The fight sequence on the construction crane between 007 and villain Molakka was mezmorizing. But would the laws of gravity allow for it to happen in real life? I mean, acrobats perform similar stunts, but could the average super spy and villain?
- of course its not realistic but it looked great, i just dnt know how they can jump from tht high and land on the other cranes and buildings. james bond was a bit clumsy in tht scene, i reckon tht other black fella was way beta at park-coring
- Q: I am Dr Crane is there anything you would like to know? i can answer all your questions?
- How are you supposed to do that! Ok here is my question: Who are you really and why have you been stalking me the past 4 nights?
- Q: any1??
- forces for cranes are dynamic , so u'll have repeated cycles of compression tension ( i assume it's a trussed crane). but generaly for a cantilever , the main forces are -ve Bending Moment +ve shear which changes the rft. bars position if dealing with R.Concrete for example
- Q: I used to buy a new tower crane that was attached to someone else's unit and (the key Gou Er). Now I have set up a company myself and bought a key, Gou Er. The question is, now how can I put it back from someone else's key dog and bring it back to my own dog?Know about the urgent urgent urgent urgent call to inform the mobile phone can ah ~ ~ ~ ~ ~ ~ thank you!
- Measures for the record and registration of construction hoisting machineryArticle 1 These measures are formulated in accordance with the provisions on the supervision and administration of the safety of construction cranes' machinery (Order No. 166th of the Ministry of construction) in order to strengthen the management of the record and registration of construction cranes.The construction and registration of the hoisting machinery as mentioned in the present Measures shall include the registration of the lifting machinery, the installation (disassembly), the notification and the use of the registration of the second.Third construction departments of the people's governments at or above the county level may use the computer information management system to handle the registration and registration of construction hoisting machinery, and establish a database.The construction administrative department of the local people's government at or above the county level shall provide the registration and registration and inquiry service of the building hoisting machinery within its administrative area.Article fourth rental, installation and use of units shall be submitted in accordance with the provisions of the lifting of construction machinery registration information, and the authenticity of the information provided by the responsible.The construction administrative department of the local people's government at or above the county level shall establish a system for the examination and registration of the hoisting machinery.Fifth construction machinery rental units or purchase building lifting units (hereinafter referred to as the "property units") in the construction machinery rental for the first time or before the installation, should be registered at the competent construction Department of the local people's governments at or above the county level to the unit of business (hereinafter referred to as the "equipment registration authority") for the record.
- Q: I'm trying to workout the best height of a truss for a ship-to-shore container crane project. The crane will have a 65m outreach, 18m center section and 15m backreach. I was thinking in the region of 2m-3m truss height.Any input would be great.Thanks
- Jimmy: The American Society of Mechanical Engineers (ASME) produces design standards for many types of cranes: see the link below. Many crane owners, licensing and governmental authorities having jurisdiction over cranes require design, fabrication and testing to ASME standards.
- Q: In Catching Fire Katniss hangs a dummy with the words Seneca Crane on it. Who is that? It sounds familiar...
- okay, i was just wondering the same thing! seneca crane is the previous head gamemaker that didnt kill katniss peeta after the 'berry' incident. u can refer back to page 20 in chapter 2! go ahead check it out. okay, gotta go do some more reading!
