某高层塔式起重机由于安装位置偏位,造成平衡臂正常拆除时与阳台相碰,施工中采取转动45°～60°角,增加平衡装置使塔式起重机安全下降拆除,保证建筑物不受损坏。
When a high-rise tower crane is out of position due to the installation position, the balance arm will collide with the balcony when it is normally disassembled. During the construction, the crane rotates 45 ° to 60 ° and the balance device is used to safely remove the tower crane and ensure the building is not damaged .
