Primary Applications
Industrial Cranes & Hoists
The YWZ3B provides reliable braking for overhead cranes, gantry cranes, and hoists in manufacturing, warehousing, and construction. The wide torque range covers everything from light workshop hoists to heavy-duty production cranes.
Port & Mining Equipment
In port facilities and mining operations, the YWZ3B handles the heavy loads and demanding duty cycles of equipment like container cranes, shipyard gantries, conveyors, and Crushers. The robust construction withstands the harsh conditions of these environments.
Construction Machinery
Tower cranes and crawler cranes rely on YWZ3B brakes for safe, reliable stopping during lifting operations. The brake’s durability handles the vibration, dust, and variable loads typical of construction sites.
Operating Principle
The YWZ3B operates on the proven spring-applied, electro-hydraulic release principle:
- Braking: When power is cut, springs apply the brake automatically
- Release: When powered, the thruster’s hydraulic system overcomes spring force to release the brake
- Fail-Safe: Any power or hydraulic failure causes immediate brake engagement
Installation & Maintenance
Installation Guidelines
- Verify mounting dimensions match your equipment specifications
- Ensure proper alignment with motor and gearbox
- Set brake clearance per specifications (typically 0.5-1.25mm)
- Connect electrical and hydraulic lines properly
Maintenance Schedule
- Monthly: Visual inspection, check for leaks, verify mounting
- Quarterly: Check clearance, inspect brake pad wear
- Annually: Full inspection, thruster service, torque test
- As needed: Replace pads when worn to minimum thickness
Frequently Asked Questions
What is the difference between YWZ3B and YWZ4 drum brakes?
YWZ3B and YWZ4 are similar in principle but optimized for different markets. YWZ3B offers the widest torque range (80-12000 N·m) with proven YT1 thruster compatibility. YWZ4 offers DIN 15430 compliance for international OEM specifications. Choose YWZ3B for retrofit applications and wide availability; choose YWZ4 for new international projects.
Can YWZ3B brakes use Ed series thrusters?
Yes, YWZ3B brakes are compatible with both YT1 series and Ed series electro-hydraulic thrusters. The mounting interface accommodates both thruster types, providing flexibility for new installations or replacement of existing thrusters. Ed series thrusters offer modern features and DIN 15430 compliance.
What is the maximum torque available for YWZ3B?
The YWZ3B series can deliver up to 12000 N·m with the largest models (YWZ38-710/320). This makes it suitable for the heaviest industrial applications including large port cranes, mining hoists, and heavy steel mill equipment.
What maintenance does YWZ3B require?
YWZ3B brakes require regular inspection of brake pad wear, clearance adjustment, and thruster maintenance. Self-lubricating bushings reduce maintenance at pivot points. Most maintenance can be performed without removing the brake from the equipment. Follow the maintenance schedule for optimal service life.
Are corrosion-resistant YWZ3B models available?
Yes, anti-corrosion treatments and models are available for YWZ3B brakes intended for marine environments, chemical plants, or outdoor applications. Specify corrosion-resistant options when ordering for these demanding applications.
