6 FAQ : How to make the structure?

Thanks to the advanced design tools, such as electro-mechanical design, CAD design, optimization design, and modular design, the tower crane proves to be a kind of optimum construction equipment that shows not only superb strength, stiffness and fatigue resistance but also outstanding comprehensive performance and reliability.

Q:live in marshes???: It's a reference to a common habitat for these birds on the Platte River at the edge of Nebraska's Sandhills.

Q:Tower crane; command; gesture: 5. hook down: arm stretched to the front, lower, and the body with an angle of about 30 degrees, five fingers stretched out naturally, with the wrist as the axis rotation.6. hook horizontal movement: small arm side to side straight, fingers together, palms outward, toward the direction of the load should be moving down to the shoulder level position.7. the hook rises slightly: the small arm extends to the top of the side, the top of the palm is higher than the shoulder, the wrist is the axis, and the palms swing upward repeatedly.

Q:I know that there's Tibetan and Fujian but what are all the styles and which is the best one to learn ( in your opinion): Fujian White Crane is short stances, short hands and close range fighting system. The other white crane is said to be from Tibet but developed in Guang Dong, southern part of China, and Hong Kong. This style emphases on deep stances, long arm movements attacks. Both of them are great styles. Steak and Lobster. which one is the best to eat? Your pick!

Q:What kinds of concrete are there in construction crane? Mainly for the construction of this area ~ ~ ~!There is no lifting machinery issued by the state what ~ ~ which detailed description of the construction machinery lifting what?: The most common are tower cranes, elevators, and freight lifts. The big construction enterprise also has the track type tower crane

Q:Any difference?: The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.

Q:I have a Holden 253 and I'm looking at a hydraulic street/strip cam, and I'm wondering which brand is better out of Crow and Crane?Cheers.: both are good id go with crane but look at the cam duration and decide whats best for your engine and if one of them comes as a kit like with your hydraulic lifters and push rods get that.

Q:I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?: Those stones are small compared to what cranes can lift. I did find this Liebherr the heavy equipment company have developed a new all terrain nine axle mobile crane that is the worlds most powerful. The Liebherr LTM 11200-9.1 has a maximum lifting capacity of 1,200 tons with its powerful 100 metre (328 ft) telescopic boom. another: Deira City Centre was the crane’s first lift as it assisted in completing the work in less than 30 hours in what would have otherwise taken an approximate 20 days. The monster machine can lift up to 1,200 tonnes and cover an area over 100m wide. The operational weight is 96 tonnes and the total counterweight is 202 tonnes. Average weight of the stones in the Great pyramid is 2.5 tonnes. So either of those cranes could lift over 400 of these at once.

Q:Remember. You heard it here first.: It's okorder /.... Judging by the fact that a Google search results in many different companies/aircraft that incorporate the term 'air crane', I would say so. But it seems that the term is usually associated with heavy-lift rotorcraft. It also appears that the term is in the public domain. So, you could call it 'JV's Air Crane' or something like that. I've Googled SkyLift, AirLift, Zeplift- all taken However, DiriLift, DirigiLift,and ZepCrane yielded no results. *I relinquish all rights to these terms

Q:What special operators should be equipped for the installation and disassembly of tower cranes?: According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel;

Q:How can you tell the difference between a mosquito and a crane fly?: Crane flies are about an inch long, sometimes larger - just the body, not including the legs.
