电动葫芦是应用广泛的小型起重设备,它的作业安全和制动可靠已引起人们的注意。如日本三菱公司生产的HY型电动葫芦装有两个制动器,即除电磁盘式制动器外,在减速箱内还装有紧急安全制动器。当锥形制动器(或电磁盘式制动器)和过载防护装置同时损坏,或发生电机轴折断等特殊情况时,安全制动器可立即起作用,以防止重物加速下降。我们生产的CD型和MD型电动葫芦只装有一个锥形制动器,很少见到装有安全制动器的电动葫芦。安全制动器的形式较 Electric hoist is a widely used small lifting equipment, its operational safety and reliable braking has drawn people’s attention. Such as Japan’s Mitsubishi Electric HY hoist equipped with two brakes, in addition to the electric disc brake, the gearbox also equipped with emergency safety brakes. When conical brake (or disc brake) and overload protection device are damaged at the same time, or the motor shaft is broken and other special circumstances, the safety brake can work immediately in order to prevent the acceleration of heavy objects.
