SB,SBD Series Safety Brakes
應(yīng)用:液壓安全(緊急)制動(dòng)器，是一種使用在低速軸(卷筒軸)上的大功率制動(dòng)裝置，可廣泛用于大中型起重機(jī)、港口裝卸機(jī)械起升以及臂架府仰機(jī)構(gòu)低速軸的緊急安全制動(dòng)。礦用卷?yè)P(yáng)機(jī)、提升機(jī)和大功率傾角式皮帶運(yùn)輸機(jī)的工作制動(dòng)和緊急安全制動(dòng)，纜車(chē)和索纜起重機(jī)驅(qū)動(dòng)機(jī)構(gòu)的安全制動(dòng)，鑄造起重機(jī)等特種起重機(jī)起升機(jī)構(gòu)低速軸的安全(緊急)制動(dòng)。
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.

主要特點(diǎn)
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.
■Convenient of installation and ease of maintenance.
