The invention provides a safety tower crane and an implementation method thereof. Tower body standard sections are detachably connected from bottom to top to form a tower body, a rotary structure comprises an inner ring and an outer ring which are rotationally connected, and one tower body standard section is sleeved with the inner ring; and a cargo boom and a balance arm are fixedly connected with the outer ring, and the cargo boom, the balance arm and the rotary structure form a whole. The crane further comprises a lifting device, and overall lifting is achieved through the lifting device. According to the safety tower crane, the mutual influences of tower crane section increase and decrease operation and cargo boom and balance arm lifting operation are effectively reduced, and the safety of the tower crane is improved.
本发明提供一种安全型塔式起重机及其实施方法,塔身标准节从下往上可拆卸连接构成塔身,回转结构包括旋转连接的内圈和外圈,内圈套在其中一个塔身标准节上;起重臂和平衡臂分别与外圈固定连接,起重臂、平衡臂和回转结构形成一个整体;本起重机还包括升降装置,通过升降装置实现整体的升降。本发明有效减小塔机加降节作业与起重臂、平衡臂升降作业相互影响,提高塔机的安全性。
