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:I am writing a story for school about working in Dubai as a crane driver but I need to know what the purpose of a Crane driver is, how much they get payed and stuff like that. And if you could tell me how a crane driver can get admission in the first place, it would be really great. Thanx. And btw, this story is for Geography.Thank you. :)
i am not a crane driver myself , but into this field of construction . get a licence as driver from authority just as a car driver. know how to drive the crane ad a driver know how to operate a crane as a operator. know the performance of the crane and its limits. the salary can vary depending on the type of crane and its special features. but not in the high end grade for sure unless its a very specialised crane operation. u can ask any thing more .
Q:my sister would like to know this for some strange and bizzar reasion
It depends on how many people are making them. Depending on skill it takes about 2-5 minutes to make a crane. If you dedicate 5 hours a day that makes 7-50 days if one person is making them. Cranes are often made for memorial. It is a Japanese tradition, especially for Hiroshima. You make 1000 cranes as a memorial for the lost lives. She should definitely get her friends to help.
Q:Iv done some research and I cant seem to find a place that might sell jibs locally here in Phoenix. Iv been considering the ProAm DVC 200 crane but I would also like to see others in like a store. If anyone has any info it would be appreciated!
I went down that path last year in the SF Bay Area in California. I could not find a store that carried any cranes or jibs - so I just started asking around. Stay away from any that use cables to keep the stage steady - we used one at a shoot - setting up is an interesting challenge. I thought I wanted the same unit you are looking at - and decided I needed to trust the crane a bit more with my HDR-FX1... I had to wait longer to save more $, but I really like the crane and tripod kit I ended up with... from Kessler Crane... I never got to see it before I bought it and I was, um... nervous... but I am glad I made the investment - and Eric Kessler is REALLY helpful and great to work with. One of the other cranes I looked at uses a heavy duty PA speaker stand as its tripod base. After watching light trees and PA speakers fall over because of leg failure, I could not bring myself to trust them to hold my camcorder. I can STAND or JUMP on the Kessler tripod and it does not budge. It is rock-steady and really strong. The Hercules head is silk-smooth and the crane-arm and camera stage are steady and easy to manipulate. After a little practice, it now takes me about 10-15 minutes from the time I start unpacking until I am ready to start shooting. That includes mounting the camcorder, setting the counterweights, mounting a portable DVD player with AV-in as the monitor mounted to the tripod-head so I can see what the camcorder is shooting and running the AV, headphone and LANC cables and making the whole thing pretty with velcro strips.
Q:Notice of tower crane
Please refer to the technical regulations for the safety of installation, disassembly and use of tower cranes in construction;The following is copy:3 installation of tower cranes3.1 conditions for installation of tower cranes3.1.1 tower crane installation unit must have the construction administrative departments issued the contracted professional qualification and heavy equipment installation engineering construction enterprises safety production license. Tower crane installation units must be engaged in the installation of tower cranes within the scope of qualification permit.In addition to the professional and technical personnel who have the qualification standard, the installation units of 3.1.2 tower cranes shall also have professional personnel who are in line with the project. The person in charge of the project, the project manager and the full-time safety management personnel shall have the certificate of safety production inspection. Tower cranes, installers, electricians, drivers, signal engineers, cable operators should have special construction operation qualification certificates.3.1.3 construction units shall sign professional contract for installation engineering with the installation units, and make clear the responsibility of both sides for safety in production. In case of general contracting of construction, it shall be signed by the general contractor and the installation unit.
Q:Hello,I live in the St. Louis area of Missouri and during the summer, Crane Flies (I call them Mosquito Eaters) fly around all the time at night. I believe that it is normal for this type of bug to be nocturnal, but lately, I've seen them flying around, jumping around, and getting in the house DURING THE DAYTIME!! (AHH!!) :0 Is there any explanation for this? If so, is there anyway to reduce their population in and around my house? Thanks for reading.Ty
Crane Fly larva are rat-tailed maggots that prefer stagnant, even polluted water. Check around your neighborhood to see if you have any stagnant pools (I've seen them in water-filled tree hollows, but this sounds like a more significant source) or polluted, but low-flowing, streams. If you find any, this might be a good opportunity to do a little environmental restoration.
Q:For example, self lifting tower crane mounted to 10 meters or 2 floor use. How do you install the third floor now? Is it necessary to remove the crane?. Then add the length of the steel frame on the base seat, and then install the crane above him If so, then 2 cranes are needed. But how is another crane installed?Ask you experts on the construction site of self lifting tower cranes how to install?. Do you use hydraulic jacks like car jacks?
It is required from the upper plus height, then the crane through the motor (hydraulic is not I don't know if not carefully studied to estimate almost) slowly up, because the installation of crane is a separate Union, only the crane is fixed on the top, and is connected to the lower die width ratio some long, above there are for the installation of people stay small table, but also it can open from the opening above the dead ground fill and then fix it by bolt, and then put the live up to OK
