Product Description:
1. 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.
4. It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
5. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
6. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
7. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

- Q:I am Dr Crane is there anything you would like to know? i can answer all your questions?
- So happy Dr. Crane that you are on the Yahoo Questions and Answers. 1. Why am I so sad?
- Q:I am writing a story for school about working in Dubai as a crane driver but I need to know what the purpose of a Crane driver is, how much they get payed and stuff like that. And if you could tell me how a crane driver can get admission in the first place, it would be really great. Thanx. And btw, this story is for Geography.Thank you. :)
- 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 .
- Q:Once, I pulled a book off a shelf in a library and found a very uplifting message on a sticky note that made my day. It's inspiring me to do the same, only with paper cranes since I love origami. I'm going to college in the city, and I was thinking about writing positive messages on them and planting them everywhere (discreetly, of course). What are your thoughts on this? It sounds fun, but what are the consequences? Is it even that big of a deal, or do you think it's a waste of time?
- I love doing things like this! Whenever my friends go to the mall we do this. We put inspirational quotes and images everywhere we can. In the pockets of clothing, on top of the sale signs, all over the cafeteria. There isn't anything wrong with doing it, and people love it! I'm sure the cranes will be beautiful and many people will appreciate them. Be sure to write look inside on the outside of each crane if you're hiding the message on the inside! This is such a cool idea, I'd love it and I'm sure it won't even be a slight nuisance to anyone. Have fun!
- Q:im doing a project and i need to know what eats sandhill cranes asap.
- Bald Eagles. They will eat anything
- Q:I know they will leave because last year they left after a few weeks. I have seen that they normally leave after a month. They annoy me and I want them gone. They have been around since the end of February or beginning of March. Does anyone else have these in their house. It seems like they are leaving slowly usually there is like 1 or 2 a day in moms room but the last 2 days there have not been any. They have been in my room, just one a day it seems like and maybe one in the kitchen. We swat them or spray them and they die eventually but when will they be gone atleast for a little while?
- Crane flies are totaly harmless to humans.They fly for some time and fall down to earth.Ants will take them away.These flies never byte or sting. Pet Cats like to play with it and catch it.They will disappear after some time. Do you know that crane flies spend most of their lives underground in their larval forms, which are known as leatherjackest?. Leatherjackets were very common round here, and are a favourite food of the local crows .These leatherjackets transform into crane flies.Summer is their growth time.
- Q:How do you erect a crane. surely you would need a crane to make a crane.?
- Modern building cranes (the tower cranes that you see on most building sites) have the ability built in to jack themselves up as the building grows. Jacks raise the crane at ground level, allowing a new section to be inserted at the bottom of the tower. But the crane arrives at the building site in pieces, and a small truck-mounted or crawling crane may in fact be required to assemble and erect the tower crane - so, except for the smallest cranes that could be put up by hand, you are correct.
- Q:job description of crane operator and truck driver?
- heavy equipment operator
- Q:Is there a talk show on the radio or TV similar to the Frasier Crane Show where people call in and tell their problems and the doctor gives them advice? One that's either in the Los Angeles area or nationally syndicated?
- Here's okorder /
- Q:My hubby just passed his crane test yesterday, and I was wondering how much they pay? He was told to ask for 50k a year..that includes crane time where he works. Can we really ask that? He sets trusses for a big lumber company in Missoula Mt. Any help would be great.
- I'm sure it depends on where you work, and what kind of crane. 20-ton bridge where I worked paid about $20k/hr, and included overtime, so that would be approaching 50k/yr
- Q:Hey,My grandma has a big country estate with a river and its her birthday coming up. She's indicated she might like another peacock (we've had them before), but I'm thinking of branching out into other birds. We tried Lady Amerhursts pheasants, but one of the dogs knocked over their cage before they were properly acclimatised and they disappeared.So, does anyone know if its possible to get storks or cranes or other big waterbirds to keep as domestics?They'd be free ranging on the estate and the river, so need to be smart about foxes and mink (ie roost in trees or go into a house). We've kept geese and ducks successfully on our river like this, so does anyone have any ideas?Or should we try again with pretty pheasants?
- Depends on where you live ? Stick to Ornamental Pheasants or Ducks,Storks and Cranes,need to be penned in at night because you will have to pinion them to prevent them flying. Try some Golden Pheasants for a try ,Lady Amherst are becoming a rare commodity and are quite expensive,if you have Foxes and Mink,then no matter what you get you will have problems these two predators.
