今天给大家带来一段机械类技术文件译文，欢迎跟帖，并祝大家新年快乐!：
a 塔机配平前，必须先吊一节标准节放在引进平台上，再将载重小车运行到配平参考位置，并吊起一节标准节或其它重物（表中载重小车的位置是个近似值，顶升时还必须根据实际情况的需要进行调整）。然后拆除下支座四个支脚与标准节的连接销轴；
before the tower crane is balanced, lift one standard module onto the intake platform, run the loaded trolley to the suggested position for balancing and lift one standard module or other heavy objects(the position of the loaded trolley in the table is approximate; it is necessary to make adjustment based on the actual situation during self-erection). Dismantle the dowels-axles connecting the four legs of the lower pedestal with the standard module.
b 将液压顶升系统操纵杆推至“顶升方向”，使爬升架顶升至下支座支脚刚刚脱离塔身的主弦杆的位置；
push the lever of the hydraulic self-erecting system to “self-erection” so the climbing frame ascends to the position where the legs of the lower pedestal just detach from the main chord of the tower body.
