意大利COMED-CT-603型自升上旋式塔机的主要特点是,液压顶升点设在塔身标准节的外侧,顶升时,每个标准节在地面由两榀L形桁架拼装好后,吊起直接就位,避免了高空拼装,缩短了顶升时间。在电气传动控制方面,采用了先进的微电子技术,通过电子控制可以使相应的吊载达到允许的最大操作速度,并能缓慢减速使吊勾和吊载不晃动。我公司自1987年引进后一直在高层住宅施工中使用。随着使用年限增长,一些控制起吊、小车等主要动作,在运行中最常用的电气控制板上的电子元件出现了老化、失效和击穿烧坏的现象。进
The main characteristic of the Italian COMED-CT-603 self-elevating upper-swirling tower crane is that the hydraulic lifting point is set on the outside of the standard section of the tower body. When lifting, each standard section is assembled on the ground by two L-shaped trusses. After the lifting, it is directly placed in place, avoiding high-level assembly and shortening the lifting time. In the aspect of electric drive control, advanced microelectronics technology is adopted. Through electronic control, the corresponding hanging load can reach the maximum allowable operating speed, and slow deceleration can be achieved so that the hanging hook and the hanging load do not shake. Since our company was introduced in 1987, it has been used in high-rise residential construction. With the increase of service life, some of the main movements such as control lifts and trolleys have experienced aging, failure, and burnout of electronic components on the most commonly used electrical control boards in operation.
