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:How did the tower crane rise on the construction site? Fifteen
With a bar of steel, each layer has about 10 or more bars of steel. When the building rises, add a few more bars to the top floor, plus a few layers. It uses the stability principle of the triangle to keep the tower crane from tilting, and it also needs to pull some cables around to keep it balanced, just like a country pole.
Q:I am a fellon, I made a mistake and I need help getting my crane certifacation. so I can work.?
lol, yeah, how about just flip my burgers.
Q:How do they get the construction cranes up the sides of buildings as they increase the height of the building?
Sometimes the structure of the crane is built onto using the crane itself, building itself into a box. Then the crane lifts itself to the higher level. This can be done many times.
Q:How does the torque of a construction crane relate to the torque of a car?
In an automobile, you are looking for torque over a wide range of speeds and loads. A crane does not need to have a great deal of speed in terms of lifting an object but does need a great deal of torque. The result is an automobile needs much more horsepower to meet its goals while a crane can actually lift a huge load with a much smaller amount of horsepower. I personally can remember a lift on one of the construction projects I was field engineer on. The lift of 650,000 pounds was made with two 85 horsepower Ford gasoline engines and two industrial gear boxes.
Q:What is the breeding season of cranes?
Mid-April to mid-June is breeding season for Florida Sandhill cranes lasts from December-June. For most other cranes, like those here in the midwestern U.S., the breeding season is March and April. I'm fortunate enough to live not too far from the Jasper Pulaski Fish and Wildlife Area where the Sandhill Cranes migrate every spring and fall. I always go to see this spectacular event.
Q:How to build a strong paper crane?
Fact: paper is relatively strong when you pull on it, but when you push on it, it easily crumples. Build your crane out of several bars. Bars that are being pushed upon by the weight need to resist the crumpling. A good way to do this is to roll a sheet of paper into a tube form to make the bars. Bars that are only being pulled on don't need to be more than a sheet of paper. A frame cranes are simple to make: www.lni.wa.gov/wisha/rules/generalsafety/images/24_d2_a-frame.gif
Q:Doing white crane kung fu?
White Crane Kung Fu combines protection and assault and makes use of the two gentle and not basic power. It additionally emphasizes organization yet evasive footwork. that's an on the spot, linear and deceptive martial paintings. this actual device is named Fei He or Flying Crane. Flying Crane makes use of the two extreme and occasional kicks yet has a marked decision for speedy hand innovations. It stresses empty-hand as properly as weapons preparation, 2-person instruments, self-protection drills and loose-sparring.
Q:How many meters is the tower crane installed on the edge of the deep foundation pit?
Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
Q:Working as a crane driver in Dubai?
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 .
