一、概述塔式起重机简称塔机,又叫塔吊。塔机是工程建设中不可缺少的一种起重运输机械,在工业建筑和民用居住建筑施工中应用尤为广泛。近年来,我国塔机行业发展很快,全国塔机拥有量增长迅猛,新机型、新品种不断涌现,塔机技术水平日益提高。有关塔机设计、制造、试验及使用的标准和技术条件相继颁布贯彻执行。国产塔机的性能和质量正在逐步赶上国外先进水平。目前,一方面建筑工地塔机林立,一方面塔机供求关系仍然很紧张,而在如何充分发挥
I. Overview Tower cranes are referred to as tower cranes, also known as tower cranes. The tower crane is an indispensable lifting and transporting machine in engineering construction, and it is particularly widely used in the construction of industrial buildings and civil residential buildings. In recent years, China’s tower crane industry has developed rapidly. The number of tower cranes in the country has grown rapidly, new models and new varieties have emerged, and the level of tower crane technology has increased. The standards and technical conditions concerning the design, manufacture, testing and use of tower cranes have been promulgated and implemented one after another. The performance and quality of domestically-made tower cranes are gradually catching up with advanced foreign standards. At present, on the one hand, there are tower cranes on the construction site. On the one hand, the relationship between the supply and demand of tower cranes is still very tight and how to make full use of them.
