How powerful is the construction CP that “helps you expand”?

Fangchenggang, a city built in Hong Kong and named after the port. It is home to 21 ethnic groups including Han, Zhuang, Yao and Jing. The superior geographical position and abundant resources make the city of Fangchenggang have a rapid economic development. For the past few years, the per capita GDP has ranked first in Guangxi.

The rapid development of the economy makes Fangchenggang, like other cities, need to crack the urban traffic congestion “urban disease”. The air corridor is undoubtedly a practical and cost-effective method of cracking. According to the urban planning, the bus town of Fangchenggang Port Area needs to install a super-long and large corridor across the avenue on the Tochigi River Avenue. A corridor with a length of 73.6 meters, a height of 7 meters, a width of 7 meters and a weight of 380 tons was installed in place without affecting traffic, and encountered a series of problems. Let's see how the Xugong crane and the experienced hoisting people form a perfect CP to overcome the difficulties.

Difficulties one: super long super heavy facade beam easy to deform how to lift

Difficulty ★★★★☆ CP with index ★★★★☆

In order to facilitate the installation, the construction unit and the experienced hoisting master of Qinzhou Juli Lifting Co., Ltd. decided to separate the whole corridor, and respectively hoisted and fixed the two façades on the support frame of the erected corridor, and then welded and assembled.

The single-sided façade of the corridor is 73.6 meters long, 7 meters high, 0.8 meters wide and weighs 140 tons. It is undoubtedly combined with cranes, but the proportion of the length, width and weight of the beam is seriously uncoordinated, if the vehicle The stability and the skill of the operator and the cooperation of the commander are biased, and it is easy to deform the facade beam during the lifting process, and the economic loss is immeasurable. Taking into account the above difficulties in lifting, the construction unit analyzed and decided to use three stable X-G generators XCA300, XCT130 and XCT110 and six experienced hoisting masters to work together.

Xugong Crane

First, divide the facade beam into three parts, one for two lifting points. The XCA300 is located at a distance of 12 meters from the installation support point and 30 meters from the unilateral elevation. The XCT130 is located at a distance of 5 meters in the direction of the center of the ç²±, and hangs 45 tons of counterweight and 21.9 meters of the boom. The XCT110 is located at the center of the end lifting point to 5 meters in the direction of 130 tons, and hangs 40 tons of weight, out of 22.5. Rice big arm. After a careful calculation, the three cranes were slowly hoisted, and the facade beams were steadily lifted under the perfect cooperation of the steel machine and the hoisting master.

Difficulties 2: Limited site How to achieve long-length beam vertical change

Difficulty ★★★★★ CP with index ★★★★★

In order not to affect the traffic, the beam is placed longitudinally along the direction of the road during the production. When lifting, the longitudinal beam placed on the extension must be rotated 90 degrees, and the road can be installed in place. The beam is 73.6 meters long and the road is 35 meters wide. How to achieve it?

Construction work

In order to solve this difficulty, the construction party uses a fixed point two fixed point method for construction. The high-tech XCA300 hangs 100 tons of counterweight, adopting the far-to-near installation method, as a fulcrum for the stable hanging beam of Dinghai Shenzhen; it has the industry's first intelligent boom system, which incorporates the latest scientific and technological achievements of XCMG. The XCT130 and the seven-section main boom have a length of 73 meters. The lightweight design allows the net red XCT110 with a weight of less than 55 tons to adopt the hoisting method of the near and far, as the younger brother runs back and forth to stabilize the beam. Slowly sent to the XCA300 direction, although the venue is limited, but with the perfect cooperation of the crane master and lifting equipment, after a day, a single facade beam is finally installed in place.

Difficulties three: overnight hoisting welding

Difficulty ★★★☆ CP with index ★★★★

After the XCA300, XCT130, XCT110 three cars and the hoisting master perfectly seamlessly docked, the task of lifting the beam to the corridor bracket was completed in an unscheduled time in a short period of time.

The last level is hoisting and welding. In order to ensure the safety and timeliness of the construction site, it is necessary to hang the beam to carry out hoisting and welding. The difficulty is also to ensure the stability of the hoisting, the vehicle is not stable, the welding points are biased, directly affecting the quality of the project, causing safety hazards, and the three X-Guru generations will not be able to complete the task again.
