YWZ₄YWZ₄ (Ed) / YWZ₄ (YT₁) / YWZ₄-A Series
Electro-Hydraulic Drum Brakes JINGU YWZ₄

JINGU's main series of electro-hydraulic drum brakes: mounting dimensions and braking torque per JB/ZQ 4388-2006, technical requirements per JB/T 6406-2006. YWZ₄ (Ed) with an Ed thruster replaces YWZ₄B, and YWZ₄ (YT₁) with a YT₁ thruster replaces YWZ₈; both cover drums of 100–800 mm and 40–12,500 N·m. YWZ₄-A (drums 160–800 mm, 80–12,000 N·m) replaces YWZ₃B. Normally closed: the spring applies the brake when power is off and the thruster releases it; self-lubricating bearings at the hinges, riveted or plug-in linings. For cranes, transport, metallurgical, mining and port machinery.
