Sprint for the Winter Olympics! Sany crane lifts up the "Olympic rings"

Recently, the Olympic five-ring structure located on the "Haituo Tower" in the Yanqing competition area of the Beijing Winter Olympics has been hoisted and successfully reached the top, with a radius of 5 kilometers clearly visible. The precise control of high-altitude hoisting and splicing makes everyone breathtaking.The total weight of the five rings is 51 tons, and the outer diameter of each ring is 12 meters, and the inner diameter is 10 meters. The base truss is spliced by H-shaped steel, with a total weight of 50 tons,The hoisting height is over 120 meters.In the hoisting process, the difficulty of the challenges can be imagined.

But the most difficult obstacle is the strong wind in Yanqing. In Yanqing in winter, the temperature can drop to minus 10 °C, and the mountain breeze blows on the buildings, making a "whining" sound. “Wind level 3 on the ground, 7 to 8 at the top of the towerSometimes, when a gust of wind comes from the top of the tower, a strong man will be blown to his feet. Tian Lei, the chief engineer of the project, said.

Trinity SCC6300 trackscraneUndertake the main crane task here, and the SAC6500T7 and SAC4500T work together to ensure that the five-ring logo is tightly fitted in the high-altitude assembly.The error is controlled within 2 mm, presented in the most perfect posture.

Tian Lei introduced: "High-altitude welding in this weather should ensure that each link is accurately in place. In order to reduce the risk caused by strong winds, the project department decided to hoist in five times, the first time the yellow and green rings below and the 1/4 part of the blue, black and red ring were hoisted in one, and the remaining parts were hoisted in turn. We have planned the hoisting route in advance and added the traction guide rail to ensure that the hoisting is always stable and foolproof. ”

The "Olympic rings" are installed on the top of the "Haituo Tower", and more than 70,000 white point light sources are installed on the surface of the entire "Haituo Tower".It has become one of the iconic landscapes of the Beijing Winter Olympics.

The overall project will be completed at the end of January, and after the completion of the "Haituo Tower", it will present the elements of the Ice and Snow Olympics in a simple and atmospheric design style, and apply for the permanent preservation of the Olympic building, becoming an important historical heritage.
