Main Features of Tower Crane

 

1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.

 

2) 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.


3)The range-change structure drives the trolley moving on the horizontal crang jib, 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. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..

 

5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

Crane? anyway,, if your store has those little pieces you can buy to eat? or if you know someone with canes,, you strip off the hard outer covering,, this has the seed buds,, plant these in 3 inches of soil and wait,, cane is slow growing!! if you google sugar cane growing or go to wikipedia you will find plenty of info google buy sugar cane seeds you will find sites to order!!
Q: I work a few blocks away and my window faces the building, now shrouded in black netting and scaffolding. I cannot comprehend how that crane got up there!!
First opf all structure engineer design the crane(wind Load+load carrying capacity+self weight+torsion+moment...etc) then designed in parts then fabricated with iron pipe, angles, girdrers. then transported to site on trucks then assembled in small pieces on ground then step by step joined with the help of crane, or even helicpoter(it was even used in CN tower)

Q: The story I'm writing that has Frank Crane in it is here. Is there a better name I could be using for the protagonist?
Names are not important. If it's bothering you, chose another name (find a list online of current most popular boys name so you chose something modern, maybe). But if you start relying on a name to put across something of the charactor you are doing something very wrong.
Q: It frustrates me every time I play one of those games i never win. Is there a secret? If so then what is it?
It depends which type of animal crane you are talking about. If it's the jumbo cranes that pick up the huge stuffed animals, they are actually set to give out a win every so many plays, however the number of the winning play varies based on the location. If you are talking about the average sized cranes, the key is to look for a stuffed animal that is light up on top and bottom heavy. This will allow you to grab ahold of the head or neck and pick the animal up. I've found the easiest cranes to win on are the ones that you pick up beanie baby sized stuffed toys. They seem to win, every time you aim the crane to pick up the head or neck. It's a great way to rack up a lot of stuffed animals. While they may not be huge prizes they are reasonable ones, and some of them are pretty cute.
Q: Tower crane body standard section connection bolt screw upward or downward, why?.
A few days ago, a special training course of mechanical equipment, a safety supervision station old experts say the screw from the upward wear, stress is the same, but if the nut screw will fall off, in order to find problems. If you can't get it off the top and bottom nut, you won't find it
