According to records, the first tower crane used in construction-related patents issued in 1900. Emerged in 1905 with fixed jib tower crane, made in 1923 the modern prototype of the tower crane, the same year the first complete modern tower crane. At that time, Germany in 1930 has begun mass production of tower cranes, and used for building construction. In 1941, the tower crane industry standard DIN8770 Germany announced.

据记载，第一项有关建筑用塔机专利颁发于1900年。1905年出现了塔身固定的装有臂架的起重机，1923年制成了近代塔机的原型样机，同年出现第一台比较完整的近代塔机。1930年当时德国已开始批量生产塔机，并用于建筑施工。1941年，有关塔机的德国工业标准DIN8770公布。

Moreover, we mensurate the reactances ofthe experimental motor by the way of direct Joad method, and verify the vaIidity of"electromotive force method ".
