Product Description:
The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for315Kn.m;the maximum hoisting load of 3t and the maximum working radius of 39m.The hoisting height of anchoring tower crane is 25m and that of climbing tower crane is 100m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards

- Q:I was just wondering this since I come from Northern Ireland and in Belfast I think they're probably the most prominent landmark but are they actually famous and if you saw them would you know where they were?
- Harland and Wolff industries is famous. But not world famous. In fact, i had to just look them up on Wikipedia just to know who they were. But in terms of history, they are quite famous. They were the ones who made the famous RMS Titanic (you know, the ship that hit an iceberg on it's maiden voyage and sunk, there was a movie based on it starring Leonardo DiCaprio and it featured a mind-numbing song from Celine Dion) edit : idk what Harland Wolff cranes are? I was talking about Harland and Wolff industries located in Belfast, Northern Ireland.
- Q:They;re ENORMOUS!!! Do they take them apart or something?
- They are broken down into smaller unit pieces and are transported by truck or rail.
- Q:Something confuses me in dragon ball:When roshi has a flash back, he says crane didn't turn evil until after mutaito fails to kill piccolo, but in the filer where goku goes back in time, crane is an asshole before picolo and roshi referred to him as a friend before the piccolo incident.Also, why in the piccolo flash back are roshi and crane bald but in the filler do they have hair and glasses?Also, why in the filler does crane have a different outfit in the filler than the other students but in the piccolo flash back he has the same outfit as roshi?
- The idea is that Crane Hermit is a selfish man that would do anything to get what he wants. In the past, Master Mutaito was there to ram some discipline in his head and have him under control. Following the events of his death and the defeat of King Piccolo, nothing could really stop him from being a selfish jerk again. Roshi probably didn't mention Crane being bad before King Piccolo's arrival because he wasn't really evil before it either. He was selfish and greedy, but not outright despicable as later... at least not that much. Roshi seeing Crane as a friend might imply that Crane had some redeeming qualities during his years as Roshi's rival under Mutaito's guidance. About their baldness, I think they shaved their heads after a while due to how monks and some martial artists tend to shave their heads. That or it's a plot hole due/filler error. It's again either a plot hole/filler error or they just switched outfits once they reached a certain level of their training, just like how you gain a different color of band as you progress in Judo and Karate.
- Q:I was wondering if this is possible. The wall we have designed is very close to an existing retaining wall. In order to properly form and waterproof the wall we would have to demo that existing retaining wall. My idea was to build it off site, waterproof it, and then crane it into its location. Is this possible? any similar methods? thanks
- If you use precast concrete sections it can be done. You can even have a decorative side if that is required. You might need to have some form of interlocking connections to tie the whole thing together. Depending on its height there might also be a need for anchors to keep it from trying to tip. Without more very detailed information it is difficult to really answer this question. As an example: depending on the type of soil and the height of the wall it is possible to remove the existing wall and install a new one in a day if you use something like a keystone system.
- Q:Will Denny Crane lose his first case on an upcoming episode of Boston Legal?
- I love Denny Crane, he amuses me and will he lose? I dunno - how many times do you think he'll actually say Denny Crane
- Q:The cantilever part has to stay at least 6-12 inches off the ground.
- Then how are you interlocking the popsicle sticks? Most projects like this allow for thread and glue. OK.. so you can glue them and, I assume, cut them. Use a truss system made out of small pieces of split sticks to build and strengthen the support of your crane and make that long arm out of a series of sticks that form an interlocking triangle when you look into the arm. Stagger the triangle pieces so that no two joints are in the same location and then glue small splints to the inside of the long pieces.at ecah of those joints. If you have no weight limit and the support column will hold it, consider filling the triangle with a coating of glue.. be sure to allow several days for it to dry. That way the glue will also add an element of strength Take your tme, use a strong glue if you have that option - like Gorilla Glue, ,and build it in sections. Be sure to let the glue dry fully before moving on to the next stage. For the triangle portion, you can use thread to bind the pieces into a triangle shape until the glue dries and then remove the thread and use light sand paper to remove any residue. for the counterweight of the cantilever, fashion a small box out of pieces of sticks and fill it with a dense glue. As the glue hardens and compacts add more glue. When the glue has fully dried, remove the sticks unless you are still within your 150 count. That way the glue serves two functios and your instructions do not prohibit this. Hope that helps
- Q:Firstly I know there is a very good club near me which does 5 lessons a week, just to let you know.Firstly could you please tell me how much of white crane is actually fun and how much percentage is kicks and how much punches.I'm a very althletic boy age 15 and I don't know much about this style. Is it fairly exciting and what I might enjoy?Thanks for you help.
- There are two types of White Crane one is Tibetan which is called HOP GAR or Bak hok it has both high and low kicks with long arm movements Fujian white crane has lower kicks and shorter arm/hand movements...At your age both will be fine
- 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:Emergency treatment of interrupted electricity during lifting of tower crane
- When the power supply fails, you should first remove the things that are stuck in the gear!
- Q:im so frustrated because ive tryed everything and im obsessed with this book it would really help if someone could find a way for me to read it for free online. i cant find it at my library.please and thank you:)?
- did you ever get to read this book
