The DC MagnelOperated Brakes (Type BE) can be fitted wíth a pedal operated (manual) hydraullc over-ride  system.The brake designation then becomes a BEM Type. Thís Iype of brake

combines a hydraulic seVsr.'inglease brake wilh a spring setJmagnetically released brake.The BεM Type shoe brake

includes all Ihe features of the índividual BE Type DC magnel operated brakes and the BM Type hydraulic (pedal) operated brakes. This hybrid brake complies with all of Ihe relevanlAISE﹒

NEMA ralings and will provide a long service life wilh the minlmum of downlime and maintenance.

• CONSγRUCTION 
• The brake bas.e，shoe holders and the shoes are manufactured from ductile iron.Fabrlcated steellinkages

﹒The magnet case and armature are made of caslsteel.AII brake hardware is corrosion resistant.

• Composite bushings utilized in all main pivot points.The“f1oalin卜linkages"provide positive braking action with equal lining wear.

• MOlded brake linings are non-asbestos and provide a constant coefficient of friction at normal operating lemperatures.
• Shoe IInings are bonded 10 the shoes dellverlng nearly twice the life over riveted or bolted liners.

• STANDARD FEATURES 練導特性
• Self adjustment of the hydraulic wheel (slave) cylinder to compensate for IIning wear.
• Top-hinged magnet prevents dirt and debris from building up between the magnet case and the armature.
• Anti-friction∞mposltebushings utilized ln all main pivot points for Improved lmpaclresistance.Class "F" insulation

-εasily replaceable magnet coil-may be replaced withoullhe loss of brake lorque.Watertight coll and terminal box

• Self-allgnlng brake shoes-prevents wheel drag Emergency brake release Floor mounting

•  Short pedal slroke for full braking power Ihrough  the use 01a dual action master  cylinder

•  Remole control bleeding system from operator's  cab

OPERATION  線作說明

During normal operation. the continuously rated magnet coil is energized，and the brake is electrìcally released. Shulting downlhe power to the brake will de-energize the magnelcoil allowing lhe

lorque sprlng 10 set the brake.

The hydraulíc po巾ion of Ihe brake funclions In the same manner and uses the same components as Ihe BM type brakes described on page 13. Wilh Ihe magnet energized. a pedal operated master cylinder assembly mounted in the operator's area，controls brake applicatìon.This arrangement  provides the operator with a smoott method  of slowing and stopping the crane.The amount of braklng force Is proportlonal10 the amount of force applied to the master cylinder foot pedal.

The single actuatlng cylinder acts directly to pull lhe lìnks/brake shoes together.The design eliminates the additional Iinks， pins

and extra wear polnts along with the maintenance associated with these items.The  cylìnder is mounted below and off 10 one side of

the brake so there is no possibilily of oil from loose fiUlngs dripping onlo the brake shoe liners or brake wheels.
