制動器

SB,SBD Series Safety Brakes

應(yīng)用:液壓(緊急)制動器，是一種使用在低速軸(卷筒軸)上的大功率制動裝置，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)低速軸的緊急制動。礦用

卷揚(yáng)機(jī)、提升機(jī)和大功率傾角式皮帶運(yùn)輸機(jī)的工作制動和緊急制動，纜車和索纜起重

機(jī)驅(qū)動機(jī)構(gòu)的制動，鑄造起重機(jī)等特種起重機(jī)起升機(jī)構(gòu)低速軸的(緊急)制動。

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.

■常閉式設(shè)計,可靠;特制碟簧施力制動,需另配液壓驅(qū)動釋放裝置。

■動作靈敏，閉合(上閘)時間短。

■可配有開閘限位開關(guān)和襯墊磨損*限限位開關(guān)，可進(jìn)行聯(lián)鎖保護(hù)和故障顯示(采用PLC控

制時)。

■高性能無石棉硬質(zhì)摩擦襯墊，摩擦系數(shù)穩(wěn)定，不損傷制動盤且對水介質(zhì)和鹽霧(海水)不敏感。

■合理的密封結(jié)構(gòu)設(shè)計和進(jìn)口名牌密封件。效果好、壽命長。

■安裝位置靈活，使用、調(diào)整、維護(hù)簡單。

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.
