**,**D Series Safety Brakes

應(yīng)用:液壓安全(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、港口裝卸機械起升以及臂架府仰機構(gòu)低速軸的緊急安全制動。礦用

卷揚機、提升機和大功率傾角式皮帶運輸機的工作制動和緊急安全制動，纜車和索纜起重

機驅(qū)動機構(gòu)的安全制動，鑄造起重機等特種起重機起升機構(gòu)低速軸的安全(緊急)制動。

Application:

Hydraulic safety (emergency) brakes are high-power brakingdevices which can be wildly used as emergency safetybrake

on low speed shafts for the lifting control and pitchingmechani** of various large and middle crane、port handling

machinery. They are also applied for the same purpose formine winder ,lifter ,elevators ,belt conveyers ,cablecars,

foundry and cable cranes and so on.

■常閉式設(shè)計,安全可靠;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)和襯墊磨損極限限位開關(guān)，可進行聯(lián)鎖保護和故障顯示(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)計和進口密封件。效果好、壽命長。

■安裝位置靈活，使用、調(diào)整、維護簡單。

主要特點

Main feature:

■Normally closeddesign, safe and reliable; specially-designed disc springsapplied.

■Swift acti** andshort braking time.

■Equipped withrelease limit switch and lining wear limit-switch can realizeinterlocking protection and failure

indication by PLC.

■Brake lining is madefrom non-a**estos hard material, which has high and stable frictionperformance, and it is

insensitive to water, salt and other environmentalagents.

■Excellent sealingensure the brake long service life.

■Convenient ofinstallation and ease of maintenance.
