The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for400Kn.m;the maximum hoisting load of 4t and the maximum working radius of 48m.The hoisting height of anchoring tower crane is 29.7m and that of climbing tower crane is 90m.

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

The products of Huaxia Group are your best choices of construction machines.

Q: What is the difference between crawler crane and tower crane?: There are many differencesThe crawler is used to transport items in a smaller range of motion (site)A tower, used for construction, stationary, or maneuvering along a railroad track.Crawler can easily reach the magnitude of 50 tons or moreMore than ten tons of tower are relatively commonTrack internal combustion engine, hydraulicTower type general power consumptionWait, wait......

Q: list of people confirmed dead from crane accident nyc?: i imagine they are injuries. regrettably those who artwork for the city authorities - a minimum of in lengthy island - are extremely incompetent and corrupt. What makes you say that No inspector ought to deliberately ignore a risky contemporary challenge ? That 's precisely what the inspector of the first crane crumple did. Oops, my mistake. He did not verify the cranes in any respect. And all those those who died lately in structure by utilising being blown off by utilising wind from large heights??!! I have in no way heard something like that in the previous. Who supplies those people the needed facilitates?? How educated are those people? the position is their union?

Q: Secured to a concrete floor with 12 30mm bolts: That can only be answered by analizing it. A crane as you are supposed to know has different loads and directions of impact due to the moving bridge, the trolley, and break loads. So what it can lift depend on the whole structure. Besides depends as much on the type of crane

Q: WHAT IS A WADDLE CRANE?: This okorder /

Q: Calculate how much power the crane has?: the crane ?? The crane is not defined.

Q: Are there any standard requirements? If so, please show me some reference materials. Thank you, 20It's urgent, online, etc.. Thank youWould you please not write down the specifications? The specific methods of operation, with what materials are written on, thank you, good, you can add points: segments can be fixed after solving this problem, usually with plastic copper (with insulating layer) and insulator is fixed on the tower body section,

Q: What type of crane done the lift?what type of object was the crane lifting?what was the weight of the load being lifted?: It is MTC 78000 in offshore industry.It can able to lift nearly 2000 tonnes and is one of the world's biggest slewing cranes.

Q: Just curious... I'm not in construction and always wondered...: The top sections of the mast beneath the crane are removed one at a time and lowered to the ground. The top section of the crane has hydraulic rams that lower it down one mast section at a time. It is hard to describe without a diagram or photos. See photos at attached link. In some design, the jacking portion is at ground level. The crane jacks itself up so a 20' section of the mast can be unbolted and slide out. Then the jack is lowered so the process can be repeated. See second link for photos and a more detailed explanation.

Q: I like cranes like the ones at restaurants and Walmart and things. I decided I want one for myself, just in a smaller size. Basically I want to put in things like plush and then grab them. Most will be under 7, though some might be larger.: This okorder /

Q: I'm not afraid of snakes, mice, spiders, or any insect, for that matter. Except crane flies. I'm not even afraid of mosquitoes! However, I've been afraid of crane flies since I was six. I live in Louisiana and The crane flies came today, exactly on the same day they came last year. I don't care about them outside but I freak out when they're inside- especially in my bedroom, the bathroom, and the living room. What can I do to a) protect my house from them and b) not be afraid of them? I'm 14 by the way.: I'm glad i'm not the only one scared of crane flies! They're huge and when you crush them eggs or poop come out. ;A;
