Characteristics of TC4808 Tower Crane

 

1) TC4808 have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

 

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 110m.

 

3) 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.

The range-change structure drives the dolly to change range on the horizontal arm, 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 of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

 

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

FAQ of TC4804 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 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 is lifting a 500kg payload straight up at a constant speed of 0.7ms-1.?
a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v² = u² + 2as: v² = 0.7² + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
Q:Why weren't tower cranes taken down in NYC and all the areas affected by hurricane Sandy?
CHEAPER TO HAVE THEM KILL PEOPLE THEN PAY TO TAKE THEM DOWN.
Q:Tower crane attached concrete pump can be? Are there any state regulations?
Yes, but consider the direction of force. ZOOMLION began production machine.
Q:Are there cranes in North America?
There okorder.com/, rather than Casmerodius!!). Your friend and her family may have always called herons and egrets Cranes - and may also recognise a Sandhill or Whooping Crane as a different species. It doesn't mean they are mistaken, just that they have learnt a different name for the birds.
Q:how do they get the construction crane onto the the tall buildings?
There are two cranes, one lifts the other and construction workers build a scaffold under it. Then the higher crane lifts the lower one and the workers buiold a scaffold under it, this continues until they are as high as they need to be.
Q:What kind of wish can I wish for with an origami crane?
You can make whatever wishes you want. Just remember that the wishes you make reflects what kind of person you are. So maybe you should make wishes you can be proud of. Also remember, if wishes were horses beggars would ride If you for example would wish that you would have $10, your wish is most likely to be fulfilled if you manage to sell each origami crane for 1 cent... Generally wishes come true if you really work for them, Not by sitting, doing nothing and wishing.
Q:how much does a crane operator position pay?
The little that I do know is that it's one of the most dangerous jobs in the construction field including working around them...so it easily pays that much...
Q:Does anyone knows the contact # or address for Crane Lake Cellars (vineyard or winery) in Napa, California?
Funny how they use a Napa address, being that Bronco has been under attack by all of the legitamite Napa wineries that pay the huge prices to grow and produce wines in Napa that resent a bulk wine producer buying cheap bulk juice from all over and labelling it with names containing Napa and Rutherford when the crap inside has nothing to do with the AVA's they hint at. They ruined the industry starting with a surplus year with 2 buck chuck pricing (per alcohol content) below boones, olde english 800 and Colt 45. For shame.
Q:Is it true that crane flies are THE most venomous insects in the world?
RE: Is it true that crane flies are THE most venomous insects in the world? I've heard that daddy longlegs aka crane flies contain the most deadly venom of all insects. The only reason they aren't dangerous or deadly is because they have no mouth or 'straw' to inject the venom. But I'm not sure what's correct. Although they cannot harm us humans,...
Q:How to fix the cable on the tower of QTZ125 type tower crane?
let the main cable and metal member completely separated, safety code for tower crane and tower crane installation, use and dismantling specification is not clear and specific practices, according to my experience, in accordance with the methods mentioned before can do check, usually meet the requirements.
