2. Lifting Technical Performance
2.1 Lifting Performance Table and Lifting Performance Curve
(1) 4-magnification Lifting Performance Table

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q: Does anyone know of any companies that sell mobile cranes suited for extreme cold? I'm aware of Liebherr and Havator's harbor cranes, but I can't find much else.Thanks: this is not my area of study but i will give you something to consider. if you are looking for a large capacity crane for use on permafrost, you wont find one. the pressure placed on the permafrost by large weights will cause it to melt. anything that is heavy, like a house, will sink in the tundra just like it will in a swamp. for houses they excavate the foundation a build a giant wooden raft that the hose floats on. in ST Petersburg, Russians preferred a mix of reeds and slave laborers corpses's to build the raft. as long as the ground is not frozen there is somebody how makes what you want. if the ground is frozen, you will only find small machinery. best of luck ps dont look to hard. lots of diesel engines work great at sub-subfreezing temps.

Q: i was reading this chapter in the book Catching fire (part of the Hunger Games Series) and this one part said she wrote Seneca Crane on the dummy with mud,, who is Seneca Crane?: u know at the end of the hunger game book...when katniss and peeta were both bout to put the berries in their mouth? and then the announcer said..no no no..and u both win, rite? the announcer was seneca crane...the capitol was mad at him for doing that so they killed him...:(

Q: what is the function of load indicator on a crane?: Two things, The maximum lift and the maximum extension of the boom. The maximum lift is based on weight and structural considerations and the maximum extension of the boom prevents the crane from turning over. The weights on the back of the crane is prevent the crane from turning over. TexMav

Q: It got me thinking.: I have not seen the movie, but I think I saw what you're talking about on a preview. I would think that the safeties involved in the control system for a crane would make it highly unlikely to happen. There is no absolute assurance, only probabilities or likelihoods. You just hope that you have enough failsafes in the system so if one part of the system fails, the others will take over, or shut the whole thing down properly.

Q: in the pit, i just lost my bike cuz johnny's crew tripped me with a chain. so no bike, and i only have my slingshot, skateboard, and some other useless stuff. dont say i can use my firecrackers or stik bombs cuz i dont have any in this pit. Also, my friend,... whatever his name is, he's there on top of the cars and junk and in the beginning he says something about a crane but i cant hear him. so everytime i pass under the crane... my conrtoller vibrates because the crane is supposed to pick up cars and such because its magnetic. so i already tried to see if when johnny goes under the crane it might pick him up because hes on a bike but it doesnt work. and i cant take him off of his bike and steal it either. i was thinking that would work because then whatshisface could pick me up with the crane.and when i try to hit him with my slingshot, it just doesnt work it would take me forever to knock him out with that puny little thing and he has a crowbar and he knocks me out so easily. HELP: sorry, i have finisheded the game but not sure which part you are talking about.

Q: What are the safety devices for tower cranes?: (3) the lifting height limiter, lifting height limiter is used to restrict access to the hook jib head or trolley before, or is dropped to the lowest point (ground or below ground Ruoganmi) before the lifting mechanism of automatic power-off and stop working, to avoid lifting hook over hoisting device touch the boom and the bad.(4) the amplitude limiting device is used to limit the boom does not exceed the limit position in the pitch. An alarm is sounded when the lifting pitch reaches a certain limit, and the power is automatically cut off when the limit position is reached.(5) stroke limiter of car stroke limiter: a trolley type jib head and root, to cut off the circuit car traction mechanism, prevent car offside. Cart travel limiter: used to prevent the crane from derailing.

Q: Is the pink paper crane used to represent Lulu?: i really dont know what i can say to that so ill just shut up

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.
