In August 22nd, "one built" housing and urban and rural construction system front-line staff, "I am a master hand" crane operator professional skills competition held in Wujiang, Jiangsu. From Suzhou, Wujiang, the city built a nexus nineteen construction companies in the construction of the 37 tower crane operator Budweiser shot.
Put the water bucket, hung onto the first predetermined circle, according to the established route through a narrow alley, finally like bowling down like five small stakes on the bracket. The operator that makes this series of movements is not on the ground, but on the 22m high tower crane.
The August 22nd tournament, held at the site of Suzhou 9th building is located in Wujiang town of Taihu. The author saw in the scene that a 22 meter tall tower crane stands on the side of the field. The center of the site draws three circles along the arc. The inner diameter of each circle is 1.5 meters, and the outer diameter is 1.9 meters. The inside of the circle is a "lane" built with a vertical bar with a width of only 1.8 meters, and a bend in the middle. On the inside of the "lane", there are 5 stents of different levels, each with a small pile of 30 centimeters high.
During the competition, the contestants should have a long and wide bucket of 0.9 meters, 0.9 meters and 1 meters on the 22 meter high tower crane, hoist from the first circle, and put them in second or third circles accurately. Then the bucket was hung through a narrow "lane" with a bend, and then the tower crane was rotated, and the bucket was knocked down by the bucket. Finally, the bucket is hoisted back to the original point. In the meantime, the bucket out ring, the bump, the inverted rod or the non - knocking wooden pile, the water in the bucket, the tower crane and the reverse are all deducted, and the game is limited to 10 minutes.
From Suzhou Hengtong Machinery Xie Jianyuan, nearly 30 years span tower crane. He felt difficult for the match. Xie Jianyuan said that the pile on the scaffold, at 22 meters above the height of a small round point, is difficult to judge the impact height of the bucket. Hanging too high, over the top; hanging too low, will knock down the support. At the same time, the 5 bracket height and spacing ranging from only 5 meters, the tower crane in the process of rotation, slow speed, high sense of L is gone; fast, water in the barrel to shake out. In August 22nd, Xie Jianyuan had a little mistake, but he still had a lot of experience and finished the game in 6 minutes and 30 seconds.
"On the construction site, the tower crane usually has the command and coordination of the ground personnel. And this competition, all by the operator, without very strong eye and rich experience, can not do. " Yang Jianqiang, the person in charge of the competition, told the author that the competition has tested the comprehensive control ability of the operator to the tower crane's swing, amplitude and lift, and strive to be quick, accurate and stable.
