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.

Q:Which kind is better, gantry crane or tower crane?: Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.

Q:how a tower crane for a high rise building construction is erected?: Depends on the type - if the building is not that tall, the tower crane could be built by any taller crane (either a mobile one or an existing one on the site). If the building is very tall, a self-erecting crane is usually used; this type has a sort of jack mechanism somewhere in the tower (usually near the bottom), so as it is needed, the existing tower can be lifted, and another tower section is inserted to raise the entire structure, repeating the process as needed as the structure the crane is building gets taller (thus, the crane is building itself as it goes along).

Q:When the earthquake happened, the children wanted to know what they could do to inform other students and raise awareness for the people in Japan. So, we decided to do a show on the earthquake, and to also making the cranes, the origami cranes.thank you! a foreigner. （detail）: To also make the cranes is the correct way to say it. To also making the cranes is incorrect.

Q:was he a realist or naturalist: Stephen Crane was a naturalist a lot like Jack London. His main themes were man vs. nature and man vs. himself in which nature is an abstract, omnipotent force that does not (and really cannot) care what becomes of the individual. In Crane's writings, man is often faced with strengths and weaknesses within himself when confronted by extremes of uncaring Nature (see the short story The Open Boat).

Q:what dose fury mean and craned?

Q:I need a web site for crane documentation. What I need, is a site, where from I can get, when needed, hydraulic and electric schematics for all kind of cranes (crane trucks, bridge cranes, etc)Thank you,: try okorder /

Q:i have a female Doberman 4months old. running here n there, we spend time with her morning and night, four days per week we go to a big ground and walking with her more than a hour per day, is it adequate? she seems very happy and waiting for us on every evening (me and my wife) also i need an advice on her crane? i have put her in some what big (5ft 4ft) place beside my front door, not fully covered but well sheltered by the house roof/. is it ok to have an open crane like that?: NO!! bl

Q:What are the basic parameters of a tower crane?: The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...

Q:What should i do to solve tower crane collapse?: tower okorder / to see if whether your trouble is one of those tower crane troubles ?may be you can solve your question under its help.

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.
