SB、SBD系列安全制动器

　　SB,SBD Series Safety Brakes

　　应用:液压安全(紧急)制动器，是一种使用在低速轴(卷筒轴)上的大功率制动装置，可广泛用于大中型起重机、港口装卸机械起升以及臂架府仰机构低速轴的紧急安全制动。矿用卷扬机、提升机和大功率倾角式皮带运输机的工作制动和紧急安全制动，缆车和索缆起重机驱动机构的安全制动，铸造起重机等特种起重机起升机构低速轴的安全(紧急)制动。

　　Application:

　　Hydraulic safety (emergency) brakes are high-power braking devices which can be wildly used as emergency safety brake on low speed shafts for the lifting control and pitching mechanism of various large and middle crane、port handling machinery. They are also applied for the same purpose for mine winder ,lifter ,elevators ,belt conveyers ,cable cars,foundry and cable cranes and so on.

　　■常闭式设计,安全可靠;特制碟簧施力制动,需另配液压驱动释放装置。

　　■动作灵敏，闭合(上闸)时间短。

　　■可配有开闸限位开关和衬垫磨损极限限位开关，可进行联锁保护和故障显示(采用PLC控制时)。

　　■高性能无石棉硬质摩擦衬垫，摩擦系数稳定，不损伤制动盘且对水介质和盐雾(海水)不敏感。

　　■合理的密封结构设计和进口名牌密封件。效果好、寿命长。

　　■安装位置灵活，使用、调整、维护简单。

　　主要特点

　　Main feature:

　　■Normally closed design, safe and reliable; specially-designed disc springs applied.

　　■Swift actions and short braking time.

　　■Equipped with release limit switch and lining wear limit-switch can realize interlocking protection and failure indication by PLC.

　　■Brake lining is made from non-asbestos hard material, which has high and stable friction performance, and it is insensitive to water, salt and other environmental agents.

　　■Excellent sealing ensure the brake long service life.
