VOLTAGES
Shunt coils are available for a wide range of voltages for continuous (8 hour) or intermiltent (1 hour) 50%，duty cycles.
The coils are designed to release at 80% of line voltage.When selecting shunt brakes for fast operation 00 DC systems，specify system voltage and use 1/2 the vollage
il with series resistance. Series ∞ils are available for the complete range of
currents.The series brake is designed 10 release at 40% and hold at 10% of the full load motorωrrent. The torque ratings obtained by the ∞i1s ∞mply with the latest A1SE-NEMA

- PATENTED SELF-ADJUSTMENT FEATURE 專利自發詢盤特性
You never need 10 adjusIthis brake for lining wear! It adjusts ftself. No troublesome mechanical linkages. star wheels，or other devices for brake adjustrr are required. The simple， automatic，dependable way in which the adjustment is accomplished is explained and lIIustrated below.
Each time the brake Is released，the end stop，attached to the brake rod，moves slighUy to the ght through the pivot block，adjusling plates and plate enclosure.
If the brake linings have worn enough so that an adjuslment is reqre ，the end stop
wlll move far enough so that an adjusting plate can drop from its upper position 10 its lower position around the brake rod. Since this adjusting plate Is not between tne end stop and the ，
ít shortens the effectlve
avel01the brall.e fod 0 1' he appliion so that the brake is again in its correct adjustment.
In this way the brakes seladjust throughout the full thickness of the IInln9s or until the linings are replaced. Thls feature delivers increased productivity and decreased maintenance lime. It also protects (he entire brake assembly from the Impact loads that can be∞me excessive as the gap between
the shoes and the wheel increases.

These brakes are designed with a minimum number of parts to provide a long service life th reduced maintenance and downtime This versatile brake， with its many standard and optional features，can be applied to a wide range of applications and environmentalconditions， where smooth，responsive stopping and holding is required.The cushioned brake action produ臼 s signifi臼 ntly less mechanil oscillations as compared 10 the DC Armature or the AC Solenoid type brakes. The lalter are expensive to maintain in terms of spare parts placement and downtime. The inherent cushioning effect makes the brake ideal for high duty cyde or jogging applications， viually eliminating the mechanicalshock loading which n lead to increased ∞mponent wear and or ∞mponent failures Sinthe growth in popularity of AC ∞ntrolled cranes，this brake has rapidly become the standa for all crane moons.It has the same high reliability normally associated with DC dapper ，but does not require an expensive transformer/rectifier to supply the DC power and improve the brake response times. CONSTRUCTION The brake base，shoe holders and the shoes are manufactured from ductile iron. Fabricated steel linkages ﹒The actuators are manufactured of a cast aluminum alloy; include double shaft seals，gasketed joints and terminal box，making the units waterproof and dustpof 。 AII brake hardware is corrosion resistant. Composite bushings utilized in all main pivot points ﹒The“floatipg-linkages" provide positive braking action with equal lining wea'r. Molded brake linings are non-asbestos and provide a constant coefficient of friction at normal operating temperatures.Shoe linings are bonded to the shoes delivering twice the life over riveted or bolted liners. .S TANDARDFEATURES Internal torque springs 一Type BT Main pivot points are fitted with anti-friction composite bushings. Replaceable，waterproof Hy-Thrust Actuator Environmentally-safe molded non-asbestos brake linings provide a constant coefficient of friction over the normal operating temperature range.Easily replaceable brake shoes from either side of brake Brake shoes are self-aligning.Convenient manual adjustment for torque and lining wear Manual release lever Floor mounting OPTIONAL FEATURES 選用特性 Extema torque springs -'TypeB'TE ﹒Time delays on brake setting(“S") and release Self adjustment for lining wear Hydraulic，pedal operated manual over-ride systems TORQUE ADJUSTMENT OPTIONS 扭力調盜-選用 The standard Type "BT" (Internal torque spring): Torque spring compression rating is fixed within the thruster. Pre-set torque setting provided by pull rod pivot pin locations (3). Torque may be reduced to 60% of maximum rating. The optional Type "BTE" (External torque spring): Provides stepless torque adjustment Torque adjustment made by rotating the nut atop the sp討ng tube assembly Torque may be reduced to 40% of maximum rating. The actual setting can be read on the calibrated torque indicator (C.T.I.) located in the side of the spring tube assembly. RESPONSE TIME 反應時間 When used on crane bridge motions， it is acceptable to connect the Hy-Thrust actuator directly across the bridge motor terminals.For crane hoist applications，we recommend the Hy-Thrust Actuator is connected directly to the AC supply and switched by a suitable 3-phase contactor. To reduce the response time an additional 15%， motor capacitors must be connected in parallel with the motor windings， and the actuator must be switched through a contactor. A typical application for this arrangement would be container cranes or similar applications SELF-ADJUSTING 自譏諷盤 Both the“ BT" and the "BTE" type actuator brakes n beed with an optional device which automatically compensates for lining wear throughout the full thickness life of the linings. The self-adjusting feature consists of a one-way operating clutch， mounted on a special pull-rod， which replaces the standard pull rod assembly. As the brake linings wea，r the actuator stroke increases. This increased movement will cause a small arm mounted on the brake linkages to rotate the clutch/pull-rod assembly a few degrees. This rotation draws the brake arms slightly closer together， compensating for the wear in the brake shoe linings.'The optionalsef-adjusting feature eiminates the time requried 10 manualy adjuslIhe inkages for brake shoe lining wear. It does not reduoe or eliminate the planned maintenance inspections as recommended in the Operation and Maintenance manual provided with the brake.

PATENTED SELF-ADJUSTMENT FEATURE 專利自我詢盤特性 You never need to adjust this brake for lining wear! It adjusts itsel，f no troublesome mechanical linkages，s ar wheels or other devices for brake adjustment are requried. The simple， automat，dependable way In which the adjustment is ac∞mplished is explained in the lIIuslration below. Each lìme the brake is released， the end stop，attached 10 the brake rod，moves slightly 10 the right Ihrough Ihe pivot block，adjust g plates and plale enc/osure. If Ihe brake linings have worn enough so that adjustment is required，the end slop will move tar enough so that an adjusting ρlate can drop from its upper position to ils lower position around the brake rod. Since this adjustíng ρlate is now between the end slop and pivot block， it shortens the e仔ectiveIravel of the brake rod on the application so that the brake is again in correcladjustment.In Ihís way， the brakes se!adjust throughout the Ihickness of the linings or untillinlngs are replaced. This feature delivers increased productivity and decreased maíntenance time. It also protects the entire brake assembly from the ímpact loads that can become excessive as the gap between Ihe shoes and the wheel increases.BRAKE SELECTION AND APPLlCATION Please reter 10Ihe following page tor technlca，l dlmensional Info何natlon on the 300M Series "BEM"- DC Magnetic Hydraulic Operated Brakes.
