3, It is original in design, reliable in operation and satisfactory in shape. 

4,Equipped with all necessary safety devices, these cranes show a good speed-control capacity,, satisfactory operationg stability and high work efficiency.

5,They are widely applied for the construction of high-rise hotels, residental buildings, high-rise industrial buildings, large-span factory buildings and tower like buildings like tall chimneys. Best after sales service will be offered which will get rid of all your worries in the purchase of our products.

 

Advantage of our tower crane:

1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.

2, suitable for the group of tower cross homework.

3, boom stability is good, combination amplitude range.

Q: A crane operator must ensure that the load is within load chart ratings for _________ and the __________ of the crane.A. Boom length; CenterpointB. Boom length; Load RadiusC. Center Point, Load RadiusD. Center of Gravity; Load Radius
B. The load radius is the horizontal distance from the center of rotation of the crane to the center of gravity of the load being lifted. The load radius is a critical consideration when determining what size crane is required for most lifts. There is generally a chart that tells what that machine will lift at any boom length,
Q: The special equipment specified by the state is a periodical inspection cycle, wherein the crane is carried out every many years
(two) small light lifting equipment, bridge crane, gantry crane, gantry crane, cable crane, crane mast, railway crane, jib crane, mechanical parking equipment every 2 years 1 times, the crane annual molten metal and hot metal 1.The rated load test, static load test and dynamic load test shall be carried out in the first test and the first periodic inspection, and the rated load test shall be carried out 1 times after each of the 1 inspection periods.The inspection process, the existence of major risks of hoisting machinery (such as special work environment, frequent accidents, etc.), inspection agencies approved by the provincial quality technical supervision department agree, can be appropriate to shorten the regular inspection period, but the short period of not less than 6 months.
Q: how does a crane operator's knowledge of where the centroid is generally located for most uniform objects help them perform their job more safely?
Usually it is the rigger who attaches the lifting gear not the crane operator who needs to know about centriods and even then the real trick is getting the slings or other lifting devices in the exact place. That tends to be a bit of trial and error unless the lifting points are clearly marked.
Q: Why do tower cranes need to be fabricated?
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure light steel wire rope (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is bonderizing, can solve the wear problems of wire rope used in the process, according to the current market situation of wire rope, manganese phosphating coating of steel wire rope price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase, so the phosphating coating steel wire rope daily use fee is only plain steel wire 30-45% rope, the use of lower cost, higher cost, smooth steel wire rope is eliminated. For reference only
Q: I have a 2 year old bearded dragon, and there r tons of crane flies flying around everywhere outside. i was wondering if she can eat them in small amounts?
I wouldn't recommend it. I couldn't tell you if they are safe, but, at the very least, there is a very real risk that they may have been exposed to pesticides and other chemicals... Even if the crane flies themselves are safe for the dragon to eat, they may be exposing him to chemicals... And parasites, for that matter. It's all around not a good idea to feed wild-caught bugs.
Q: so yeah i know that cranes do the main work but i guess there are no such really toll cranes to do that with skyscrapers ?
That is a good answer. Ordinary cranes build the steel frame to a height of perhaps 60 feet. The frame is designed so a specially designed crane can climb up the side (like climbing a ladder) to about 50 feet where the climbing crane can complete the frame to about 100 feet, then the crane can climb to the 90 foot level and build the frame to about 150 feet etc. Another method is the floor at about the 60 foot level is completed and extra strong. A crane is assembled on that floor and can complete the steel frame to about 100 feet where another extra strong floor is built. The crane at 60 feet is then dismantled and moved to the floor at the 100 foot level, or perhaps this is a second crane. Repeat until the full height of the building is frame work. As cranes are removed at the lower levels, more floors can be installed and some of the finishing work done. Either way, you can see why very tall buildings are very expensive. Likely both methods are used for some very large and very tall buildings. Neil
Q: I have always wondered how they get cranes off the top of huge buildings when they finish building them.I have had many people tell me how they THINK the cranes are taken off. But I want to know for sure. Can anyone give me some evidence? A web site or something??When I say big building I mean like 100 storeys.I have been told things ranging from a helicopter takes them offToThey build tracks down the side of the building and drive it downAndThey pull it to pieces and take it down the elevator.These MAY be real but sound like wild guesses to me.So does anyone know the answer?

Q: What are the main technical parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
Q: What are the working mechanisms and safety devices of tower cranes?
A safety device: four limit: height limit, amplitude limit, slewing limit, travel limit; three insurance: luffing rope insurance, car insurance broken shaft, the hook to prevent falling insurance; two limit: torque limiter, weight limiter on these roughly.
Q: I was watching Batman Begins and at the end Gorden says that he hasn't caught Crane. Since the villians in the next Batman movie are going to be two-face and the joker will Crane make a reapperance in the thrid movie (if there is one)?
Probally not. In Batmans world, the villians are usally always on the lose, so they were probally playing that out, like batman would go against him again, but they typically don't do that in movies. Especially with the scare crow. He wasn't that great of a villian, atleast not good enough to top the joker or two face.
