普通摩擦式制动器一般是按间歇制动设计的。两次制动之间一定要有制动器散热的间隔时间,才能使其恢复到原来的工作情况。山地林区使用绞盘机作集运材索道的动力和控制设备时,常常因其连续制动,没有散热间隔时间,或间隔时间过短,因而制动器温升过高,以至制动能力降低而发生事故。 Ordinary friction brake is generally based on intermittent brake design. Between the two brake must be the brake cooling interval, to make it back to the original work. When using a winch as a power and control device for a ropeway in a mountainous forest area, it is often the case that an accident occurs because the brakes are too warm due to their continuous braking, no cooling interval, or too short intervals. .
