摘要
本文对四连杆组合臂架变幅机构工作过程中货物水平波动情况的分析指出,计算水平波动的差值时必须计及起升机构钢丝绳补偿过程的影响。在一台25t门座起重机上进行的实测证明了这一点。
Analysing load fluctuation during derricking of a four bar luffing mechanism this paper points out that, when calculate such fluctuation value, the compensation of steel wire rope must be taken into consideration. This is proven by measuring the actual values on a 25t portal crane.
