The click rate N shall be determined with 18 working cycles per hour; each cycle shall comprise:
喀呖声率N 应以每小时18个工作周期确定;每一个周期应包括:
a) on hoists having only operating speed: lift; pause; lower; pause;
对只有一种运行速度的升降机:提升、暂停、降低、暂停;
b) on hoists having two operating speeds with both the following cycles, alternating:
对有两种运行速度的升降机,有下面两个互相交替的周期:
Cycle 1: fine lift (creep speed); lift (full speed); fine lift; pause; fine lower; lower (full speed); fine lower; pause;
周期1:慢提速(蠕变速度),提升(全速)、慢提升、暂停、慢降低、降低(全速)、慢降低、暂停;
Cycle 2: fine lift; pause; fine lower; pause.
周期2:慢提升、暂停、慢降低、暂停。
NOTE For shortening the time to be used for testing the cycles may be accelerated, but the click rate is calculated on the basis of 18 cycles per hour; care should be taken not to damage the motor by exceeding duty cycle.
