APPLICATION:

●Explosion protected electro-hydraulic drum brakes can be extensively used for deceleration and stop/braking of various mechanisms in various belt transport, port handling, hoisting, metallurgical and building machinery which have explosion protected requirements.

STANDARDS COMPLIANT:

●The connection dimension and braking torque parameters of YWZ5 series brakes are in accordance with GB 6333-86 standard, and the technical requirements are in accordance with JB/T6406- 2006 standard;

●The connection dimension and braking torque parameters of YWZ4 series brakes are in accordance with JB/ZQ4388-86 standard, and the technical requirements are in accordance with JB/T6406-2006 standard; .

●Supporting Ed series explosion-proof electric hydraulic thruster, explosion-proof mark: ExdIIB T4 Gb (factory explosion-proof )/Ex tD A21 IP65 T130"C ( dust explosion-proof ).

MAIN FEATURE:

●Brake lining is of clamped integral forming structure, which is easy and quick to replace.

●(YWZ5 Series) 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 service life. Lubricating is unnecessary during operation.

●(YWZ5 Series) Enclosed spring tube protects spring from damage and contamination.

●The Ed series explosion protected 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.

OPERATING CONDITION:

●Altitude: <2000m

●Ambient temperature:-20°C - + 40°C

●Relative humidity:≤90%

●Operating duty: intermittent (S3- 60%) and continuous (S1).

●Voltages: three-phase AC, rated voltage is 380V~460V, frequency is 50Hz/60Hz.

●Special requirements can be discussed before production.
