YWZ5, YWz9,YWZ9 A,YW SERIES EL ECTRO-HYDRAULIC DRUM BRAKES

APPLICATION
●Electro-hydraulic drum brakes can be extensively used for various mechanism deceleration andstop 1 braking of various belt traneport, port handing, hoisting, meallurgical, mining and bulding machinery.

MAIN FEATURE
●Brake ining is of clamped integral torming structure, wnichis easy and quick toreplace. Brake lining of various materials such as semi-metal (non-asbestos) hard and hal-nard, sol (include asbestos) substance are availalble for customer 10 choose.
●Main hinge points are equipped with sel-uricating bearing, making high flincy of rarsmission, kong serice lf.
Lubricating is unecessary during operation:
●Iterocking shoe cearance balancing device and shoe aut-aligning device constanty equalize the clarance of brake shoesonbottaides and make adjustment unessary, completely avoliding brake ining one slide slicking 1o brake wheel.
●Enclosed spring tube protects spring trom damage and contamination.
●Brake dloses in caseof power fllure (F ail Sale Princple), Braking by s0og power. Litingby thrustor.
●The equipped series ol thrusters are characterized by lexible action and long operatingte.

STANDARDS COMPLIANT
●The dimensions and braking torque parameters of YWZ5 and YW29 senas brakes comply withGB6333-86 standard, technology requirements comply with JB/T6406- 2006 standard.
●The dimensions and braking torque paramelers ol YWZ9-A series brakes cxmply wilth JB/ZQ4388-86 standard, technology requirements comply with JB/T6406-2006 standard.
●The dimensions and technology requirements ofYW series brakes ormnply with JB/T6406-2006 standard, braking torque parameters comply with DIN 15435 standard.

OPERATING CONDITION
●Ambient temperature: -20°C~+ 50°C
●Relative humidity;≤90%
●Voltages; AC 3 phase 380V, 50Hz ( Other voltage can be made as required)
●Operating duty: Intermittent ( S3-60%.1200 times per hour ) and continuous(S1)
●Special requirements can be discussed before production.

OUTLINE AND INSTALLATIN DIMENSION

OPTIONS AND ACCESSORIES (SELECTION)
●Brake lining of various materials are available for choice, including half-metal (no-asbestos) hard and half-hard,soft (include asbestos) substance.
●Hand release lever(S1 or S2).
●Limit switches and monitoring devices for (K1or K2).
●Brakes with pad wear self-compensating device can realize the stepless self-compensation of shoe clearance and brake torque when pad worn.
●K3 Lining-wear Jimit- switch, equipped which signals will shown wear of lining reaches the limit.
( Note: self- compensation device should be equipped in application M )
●When use such thrusters that with descending delay valve, the delay close of brake can be realized, which can meet requirement some specific occasion.
