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: What kind of steel used for  tower crane ?

A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.

 

Q: What about our  tower crane  warranty?

A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.

 

Q: What is 3 main mechanism of the  tower crane ?

Q: Can you equip with light on  tower crane  jib, monitor, remote control and anemometer?

A: Sure. All of these could be provided with extra cost upon the clients' requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.

Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:in the sentence , stephen crane wrote..?
Transitive - because it has an object The Red Badge of Courage. . Generally, if you can put the word something after a verb, it is transitive. Stephen Crane wrote something .
Q:two cranes that are directly opposite of each other are used to lift a 2000lb. cargo container from a ship.?
So I can't tell whether the cargo container is one ton (2000 lbs.) or ten tons (20,000 lbs.). For doing the problem, I'm using 2000 lbs., so you might have to multiply the answers by 10. Also, I'll use A and B for the cranes instead of I and II. (Vertical): A sin 30° + B sin 45° = 2000 == A + √2 B = 4000 (Horizontal): -A cos 30° + B cos 45° = 0 == -√3 A + √2 B = 0 Solve those equations simultaneously to get A = 4000/(1+√3) = 1464 lbs. and B = √(3/2) A = 1793 lbs. (Answers) The vectors are: A = 1464 (-i cos 30° + j sin 30° = -1268i + 732j (Answer) B = 1793 (i cos 45°i + j sin 45°) = 1268i + 1268j (Answer)
Q:how does a electro megnetic crane works?
Current sent through a coil of wire creates a magnetic field, which can be used to pick up ferromagnetic objects. Turn off the current, and the field will turn off (although it might take a few seconds to turn off all the way), dropping the object.
Q:Origami Crane?
These okorder.com It takes quite a few tries to get it right, but once you do it is easy.
Q:The crane stance and its applications...?
Great question. This is one of those stances that I believe can be more static in nature. I think this stance, as Kokoro points out, is a great example of a lying-on-the-floor technique without actually having to lie on the floor. There are 3 kinds of crane stances, that I'me aware of: 1) the left foot is placed behind the right knee and the left foot's shin is perpendicular to the floor 2) the left foot is placed next to right knee and the left foot's shin is perpendicular to the floor 3) the left foot is placed next to right knee and the left foot's shin is ANGLED (sticks out to the left) to the floor in method 1), the application can represent a bind, hook, or pull toward you, of opponet's knee/shin while standing or lying down. in method 2), the there are a couple of applications: 2a) it is a on-the-floor position where you are mounted; your knee up represents keeping the distance open between you and opponent. 2b) it is a chamber of sorts to a jumping front snap kick (some call this a crane kick, which was a question that was asked about this a day or two ago) - and Shadam mentions this again in this question 2c) it is a check or block of a kick or weapon, as Liondancer mentions. in method 3), the application represents that your opponent is kicked to the inside of the knee: either to disable or to sweep.
Q:what year did ichabod crane die?
Ichabod Crane is a fictional character in Washington Irving's short story The Legend of Sleepy Hollow
Q:Safety rules for tower cranes
Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.
Q:What is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q:airsoft gun crane stock to full stock switcharoo?
Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!
