    行车制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)的制(zhi)动(dong)能力(li)的检测很重(zhong)要,在(zai)空(kong)载状(zhuang)态下,起(qi)升(sheng)离(li)地1米距离(li),让(rang)工(gong)(gong)作(zuo)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)和安全制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)上闸(zha)(zha),然(ran)后(hou)再让(rang)工(gong)(gong)作(zuo)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)松(song)闸(zha)(zha),检查(cha)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)是(shi)否(fou)(fou)能刹住卷筒,重(zhong)复(fu)三(san)次。 在(zai)额定载荷状(zhuang)态下,起(qi)升(sheng)离(li)地1米距离(li),让(rang)工(gong)(gong)作(zuo)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)和安全制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)上闸(zha)(zha),然(ran)后(hou)再让(rang)工(gong)(gong)作(zuo)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)松(song)闸(zha)(zha),检查(cha)制(zhi)动(dong)器(qi)(qi)(qi)(qi)(qi)是(shi)否(fou)(fou)能刹住卷筒,重(zhong)复(fu)三(san)次。

    行车制动器功能试验(动态试验) 是什么呢,在空载时,将安全制动器失电抱闸的时间调整为滞后于工作制动器0.3 s。吊具以额定速度上升或下降,模拟断轴和超速故障,使安全制动器和工作制动器失电抱闸,检查安全制动器是否滞后工作制动器抱闸,重复三次。
