We currently offer a variety of tower cranes which are broadly classified under the Topless STT series, the ST series, the Luffing STL series and the Derrick QD series, as well as crawler cranes and modified vehicles.
Yongmao tower cranes have not only been working for various domestic projects like hydroelectric power plants, nuclear power plants, shipyard, wharf, bridge, aerospace etc. but also acting in numerous construction projects all over the world. Yongmao appreciates the reliance and confidence given by its valuable users all over the world and feels very proud of its ability and capability to contribute value added services to its users both at home and abroad.
- Q:Do they need another crane to get the concerete blocks to the top? And how do they move the blocks from one end of the crane to another. This has been bothering me for some time so anyone who knows the answer I would love to hear it!
- Its simple man, The company produces the concrete blocks called as hollow blocks also, they are lifted up using man power or lifts or cranes, dont know what was difficult to you in understanding that.
- Q:QTZ63 (Q5610) tower crane power, how many power parts, name, model specification, product number, date of appearance
- All the details of the equipment are availableAs for power, it depends on the specific configuration of the frequency conversion and non frequency conversion will not be the same
- Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
- According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:The use of 4.0.15 tower crane height of more than 30m should be equipped with obstacle lights, jib root hinge height of more than 50m should be equipped with anemometer.
- Q:Please no direct translations. I need the official name of the whooping crane in French.
- grue de huée
- Q:What are the safety devices in a tower crane?
- (1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.
- Q:I still cannot grasp how a crane was taken apart on a building with no roof
- They used a climbing crane , and who said that the building has no roof? the crane parts can be dismantled on site and removed either by helicopters or using the construction lifts
- Q:what do you think happened to ichabod crane?
- He got into porcelain work and designed the first modern toilet. When you see an industrial or residential toilet with the Crane mark and name on it, know that it's predecessor was made by the man who faced the Headless Horseman. After that fateful meeting, he had an extreme interest in efficiently removing solid human waste.
- Q:How do they get the cranes and counterweights down off the top of buildings when finished?
- sometimes they dont. i have heard of buildings where they left the crane body as the structure for the elevator
- Q:You know those big cranes that sometimes hang above constructed buildings. I usually thought a crane is used to build that crane but then how is that first crane that built the crane get there in the first place?
- The first crane generally arrives on a trailer or on it's own wheels.
- Q:I know how to make cranes and I'm pretty fast at doing so but in pictures I see of crane leis the cranes look like they're folded differently so that they can be stacked on top of each other.. Can anyone teach me how to fold like that so that I can make a paper crane lei?
- But I do different from step 11 on Step 11: Normally they fold along the red line. I dont. On step 10 you see the cross line in the center +. I then fold the right pointy toward the center. Do the same for all. Step 12: I the filp the right top layer to the left, same with the back side. Step 13: fold the bottom point to the top(one layer only) filp to back side, do the same. Step 14: flip right layer to the left again, same with the back side. Step 15: Pull and done.
