目前,我国城市住宅建筑还是以砖混结构为主,十层以下的多层建筑较多,且常以塔式起重机代替井架作为垂直运输之用。一般,塔机的起重量为1～2吨,臂架长度为20～25米即可满足砖、灰、预制板的吊装任务。本文仅对建筑用轻型塔式起重机的起升电机选择问题提出一些粗浅看法,以供同行参考. At present, China’s urban residential buildings are still dominated by brick-concrete structures, and there are more than ten multi-storey buildings, and tower cranes are often used instead of derricks for vertical transportation. In general, the lifting capacity of the tower crane is 1 to 2 tons, and the length of the boom is 20 to 25 meters to meet the lifting task of brick, ash and prefabricated panels. This article only gives some superficial views on the selection of hoisting motor for building lightweight tower cranes, for reference by peers.
