多绳提升单根钢丝绳张力不得偏离全部钢丝绳张力平均值的10%。用以往方法监视钢丝绳张力的变化,只能间隔较长时间(如四星期)后在设备停止状态下进行。为了减少钢丝绳的附加动应力,用载荷状态控制提升电机和制动闸以及在整个提升行程或在紧急制动与重载运输等状态下对钢丝绳张力的控制,连续监视是必需的。为续连测量钢丝绳张力,采用感应线圈
Multi-rope hoisting Single rope tension shall not deviate from the average of all rope tension 10%. The conventional method of monitoring changes in the tension of the rope can only be carried out with the equipment stopped after a long time (for example, four weeks). Continuous monitoring is required in order to reduce the additional dynamic stress on the rope, to control the hoisting of the motor and brake using load-state control, and to control the tension of the rope over the entire lifting stroke or under emergency braking and heavy-duty transportation. Continued measurement of wire rope tension, the use of induction coil
