FAQ of TC7021 Tower Crane

 

Q: What is the principal to quote the right tower crane to the client?

A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.

Second, we need to know what the foundation requirement from the client is. (Fixed/undercarriage/ undercarriage with traveling system), mast section type (panel/integrated), power supply source (voltage, ampere and frequency), the distance between the machine and power supply……

Third if there are special needs, we could suggest proposal according to clear data provided by the clients. End-user, as construction machinery buyer, knows the site situation well and should make decision, such as the machinery specification, type…….

 

Q: What about our tower crane's 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?

A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.

 

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: A crane that docks is capable of doing 550 J of work. How high can it lift a load that weighs 45N?
A crane can lift it's rated limits to full extension. Provided 45N is within it's rated capacity, it can lift it as high as the crane can lift items.
Q: is there something that i can add to my bug zapper to attract these bugs and kill them faster?
they might be breeding somewhere close near your window. Check for magets which turn into flys and spray some raid out there. Get a screen on your window and get rid of any food or drink that they mind want you to share with them.
Q: More specifically, do Sandhill Cranes eat squirrels?
NO!!!!!!!!!!!!!!!
Q: as the crane cabin temprature is very high which is not good for equipment pls advise which air condition is good for colling
Any crane worth it's salt can take the temperature but for the operator you can do a Coleman RV Air Conditioner.
Q: what does dog everything mean in crane lift lingo?
i think it means to stop.
Q: how do you win at the crane game?
im the master of the crane game. You gotta scope out the animal first! If it looks heavy then dont even bother. Whenever you grab hold of something its gonna pull it up and shake when it hits the top right? Thats why you go for something close to the hole it drops in. They have one where I work so I lock the wheels, grab the animal and pull the whole machine forward so that it just falls in the hole lol.
Q: How to crane fly out of your room?
The crane fly might look a little scary, but they really are harmless. They do not bite people. But you don' t want one in your bedroom. Just open the window and get a towel and chase him out. You may have to get a ladder because he may want to go to the ceiling.
Q: What association does Wing Chun have with Fujian White Crane (Tiger-crane) kung fu?
Fujian White Crane is not Hung Gar or Tiger Crane. Southern White Crane, or Gu Lou Kuen (Ancestor Fist) is the predecessor to Goju-ryu karate. Goju and GLK emphasize the sam jian ma, sanchin dachi, or three battles stance, and rootedness, body conditioning, and strong shoulders and arms. The power comes from the rooted base and strong arms. There are rumors that Wing Chun is derived from Ancestor Fist, but philosophically, technically, tactically, and strategically, the styles are extremely dissimilar except for the short range fighting. Wing Chun is also rumored to be created by Ng Mui or Wu Mei, the Buddhist Nun. But the resemblances between modern Wing Chun and styles named after the nun are few and superficial. Wu Mei emphasizes power generation in numerous ways and continuous attacks. Wing Chun emphasizes deflection and power generation by shifting the feet, and simultaneous attack and defense. Wu Mei also has a full suite of weapons, and Wing Chun only the pike and butterfly sabers. Wing Chun is a style created in the Shaolin Temple, but it is probably closest to Hsing-I Kuen or Hsing Yi Quan in training with their chi sao or sticky hands practice.
Q: Why are electromagnets on junkyard cranes generally circular in shape?
Easier/more efficient to make the electrical coil circular than any other shape I guess.
Q: I have preliminary data: up to 2 tons of weight; work range of 40 meters; lifting torque 800KNm; lifting height 45m.. I encountered problems in the design, and some of its specific reference, I would like to ask here, for example, how much is the weight of its whole machine, how much is the balance weight, the balance of the radius of gyration? Super boom weight? (it's better to have the approximate weight of each component). And when I design this tower crane, is it necessary to use planetary gear for the gear reducer?Thanks to your advice, Liu is here to thank you
The weight of the whole machine is 36.1 tons (independent height). Its balance weight is 15 tons, and the balance weight is 11.82 meters. The boom weight is 5.72 tons. It is necessary to use planetary gear.Usually use two rotary speed reducer of 8000 nm.
