Emergency Brakes for Cranes: The Proactive Approach to Safety

How Emergency Brakes Work

Emergency Brakes are are used on the low-speed side of the crane and must provide sufficient torque to overcome a low-speed failure such as a gearbox, coupling, or other transmission failure which effectively renders the VFD and high-speed stopping/holding brakes useless from preventing a load from falling.  Therefore, the emergency brakes must be mounted on the drum and will provide the required torque to stop the load from falling.

To calculate the required torque, you multiply full motor torque X gearbox ratio X service factor.  You may also calculate torque using line pull and number of falls.  Typically, these brakes must possess a great deal of torque and there are multiple disc and drum combinations available to meet the required torque values.  Brake packaging is also largely dependent on available space.  For instance, the disc can be mounted to the flange of the drum, in the middle of the drum, or sometimes the drum is extended to enable the disc to be mounted.  This can be challenging when performing retrofits of existing cranes, but Kor-Pak possesses the skills and experience to successfully package an E- Brake system.

Magnetic Emergency Brakes

Magnetic Emergency Brakes

Emergency Disc Brakes for Cranes are Spring-Applied and either electric, hydraulic, or air released.   Magnetic Caliper Disc Brakes are ideal because they have fewer moving parts than their alternatives and are also cleaner than hydraulic brake alternatives.  In some instances, magnetic brakes are required in explosion-proof packaging due to industry-specific requirements such as Nuclear applications.

Hydraulic and Air Caliper Disc Brakes provide the highest torque values and are inevitably the brake of choice for extremely high torque requirements.
