KEB load brakes are engineered specifically for demanding hoist and winch applications. These parking brakes mount directly on the drum side of hoisting equipment, delivering reliable performance with hushed operation. Their compact footprint enables integration into space-constrained winch designs.

Product Details
Fail-Safe Technology
Power-off spring-set (failsafe) brake engagement is ideal for safety-critical applications like hoists and winches.
The spring pressure automatically activates the brake when electrical power is cut off, maintaining secure load retention during system failures or power outages. The fail-safe operation of this brake system makes it suitable for applications that need vertical load retention and safety functions.
Quiet Operation
Noise-reduced design features are standard. Less than 65dB measured at 1 meter away. The noise-reduced design provides exceptional value to users who need silent operation in their performance venues and public spaces, including theaters, concert halls, and recording studios.
Versatile Mounting Configurations
Integrated mounting flange options. Generic flange for bulkhead mounting. Or, SEW and KEB gearmotor patterns. The flexibility of the flange options simplifies integration into OEM designs and retrofit projects. Mounting compatibility ensures easy alignment with VFD-driven motor systems or with a hoist brake motor assembly.
Enhanced Control and Monitoring
Manual hand release and microswitch options. These options provide the operator with manual control and state monitoring for added safety and convenience. The microswitch allows for brake status verification, while the hand release offers mechanical disengagement without power.
