Application: 

QW,QWZ5 series pneumatic drum brakes can be extensively used for various mechanisms deceleration and stop/braking of various hoisting, belt transport, port handling, metallurgical and building machinery which are equipped with pneumatic source on site.

STANDARD COMPLIANT:

1. The dimensions and braking torque parameters of QW series brakes comply with JB/T6406-2006 and DIN15435 standard, technology requirements comply with JB/T6406-2006 standard.

2.The dimensions and braking torque parameters of QWZ5 series brakes comply with GB6333-86, technology requirements comply with JB/T6406-2006 standard.

MAIN FEATURE:

●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 fficiency of transmission, long service ife.

Lubricating is unnecessary during operation.

●Enclosed spring tube protects spring from damage and contamination.

●Brake lining is of card-mounted and entirely-shaped structure, which is easy and quick to replace.

Brake lining of various materials such as semi-metal (non-asbestos) hard and half-hard, soft (non-asbestos) substance are available for customer to choose.

●New type of air cylinders are adopted, which work acutely and have long life.

●Brake closes in case of power failure (Fail-Safe Principle). Braking by spring power. Pneumatic release.

OPERATING CONDITION:

●Ambient temperature: -20℃ - +50℃

●Relative humidity:≤90%

●Operating air pressure: 0.5-0.7Mpa

●Operating duty: intermittent (S3- 60%, 1200times per hour) and continuous(S1)

●Special requirements can be discussed before production.
