1、DLZ系列电动轮边制动器DLZSeriespower-drivenwheelbrakesDLZ系列电动轮边制动器主要用于室外大中型起重机及港口装卸机械工作状态下的防风和非工作状态的辅助防风制动。电动夹轮器一般只用于被动车轮上，并进行直接制动，可有效防止被制动的车轮在风力作用下产生滚动位移。Application:DLZseriespower-drivenwheelbrakesaremainlyusedforwindbrakingunderworkingstateandauxiliarywindbrakingundernon-w

3、用全密封结构，防护等级高,使用寿命长，体积小，结构紧凑、安装简易；■采用电机通过齿轮减速驱动滚珠丝杆幅的结构作推动装置，提高了电机效率，使得制动力大，动作准确迅速。且无油管、密封件老化、液压件磨损等现象；无漏油(有利于环境保护)、无力、卡死等故障；■采用电磁常开离合器，制动器常时间打开依靠电磁铁维持，减小制动器长时间开闸使用能耗采用高性能的高性能摩擦衬垫与轮缘侧面形成摩擦副，材料对环境适用性好，摩擦系数稳定，对水和盐雾(海水)不敏感；■单台设备可设置多台轮边制动器，使整机具有较高的防风能力；■能够实现电动防爬器、夹轨器等轨道作
4、用式防风装置无法实现的，在紧急状态下，实施动态紧急制动的功能。并带有逐点成对释放功能可减小紧急制动时对设备的冲击。■通过电控可实现各种自锁保护功能。如风速仪，速度传感器等设备控制的自动制动、手动制动、系统联机互锁集中控制等功能；■每台电动轮边制动器都由系统单独控制，便于监视和故障排除。DLZ系列SeriesMainfeature:■Normally-closedtype,safeandreliable;discspringappliedandelectricopen,electricmagnetic-keeping;selfc
