STANDARDS COMPLIANT
●The dimensions and braking torque parameters of YWZ8 series brakes comply withJB/ZQ4388-86 standard, technology requirements comply with JB/T6406 -2006 standard.
●The dimensions and braking torque parameters of YWZ8-A series brakes comply with GB 6333-86 standard, technology requirements comply with JB/T6406-2006 standard.

附加装置(选择) OPTIONS AND ACCESSORIES (SELECTION)



●备有半金属(无石棉)硬质和半硬质,软质(含石棉、无石棉)等不同材质的制动衬垫供用户选择。
●手动释放装置(S1或S2);
●(K1或K2)限位开关和监控装置;
●推动器可通过带延时阀实现制动器的延时释放或闭合。
OPTIONS AND ACCESSORIES (SEL ECTION)
●Brake lining of various materials are available for choice, including half- metal ( no-asbestos) hard and halt-hard, soft ( include asbestos) substance.
●Hand release lever(S1or S2).
●Limit switches and monitoring devices for (K1 orK2).
●When use such thrusters that with descending delay valve, the delay close of brake can be realized, which can meet requirement some specific occasion.

主要特点MAIN FEATURE



●制动衬垫为卡装式整体成型结构,更换十分方便、快捷。
●联锁式退距均等装置,使用中始终保持两侧瓦块退距均等,避免退距不均使一侧制动衬垫浮贴制动轮的现象。
●主要摆动铰点均设有自润滑轴承,传动效率高,寿命长,使用过程中无需润滑。
●采用Ed系列推动器配套,动作灵敏,寿命长。
●常闭式设计,(断电)弹簧制动,(通电)推动器释放。
MAIN FEATURE
●Brake lining is of clamped integral forming structure, which is easy and quick to replace.
●Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.
●Main hinge points are equipped with self-lubricating bearing, making high efficiency of transmission,long ser vice life. Lubricating is unnecessary during operation.
●The Ed series thrusters are characterized by flexible action and long operating life.
●Brake closes in case of power failure (Fail- Safe Principle). Braking by spring power.
Lifting by thruster.
