What does “spring-applied, power-released” mean in crane braking?
“Spring-applied, power-released” describes a brake design where mechanical springs apply braking force by default, and external power is used only to …
Read moreWhere are electromagnetic motor brakes typically used on overhead cranes?
Electromagnetic motor brakes are commonly used as compact hoist motor brakes or auxiliary brakes on smaller overhead cranes, wire rope hoists, chain …
Read moreWhat’s the difference between dynamic braking and static holding?
Dynamic braking refers to slowing or stopping a rotating system while it is moving. It requires the brake to absorb kinetic energy and convert it into …
Read moreAre electro-hydraulic disc brakes better for high-duty hoisting?
In many high-duty hoisting applications, electro-hydraulic disc brakes can provide performance advantages, especially related to heat management and …
Read moreCan industrial brakes be used for emergency stopping only?
Yes—many brakes are intended primarily for emergency stopping and holding, especially in fail-safe configurations. In such systems, routine speed …
Read moreHow do I prevent overheating in high-duty-cycle braking?
Overheating is usually the result of too much braking energy over time. Prevent it by verifying both torque and thermal capacity during selection. …
Read moreWhere are electro-hydraulic drum (block) brakes commonly used on cranes?
Electro-hydraulic drum (block) brakes are among the most common crane brakes because they combine strong torque output, reliable fail-safe action, and …
Read moreWhat happens if brake voltage is unstable or incorrect?
Incorrect or unstable voltage can cause serious brake performance issues. If voltage is too low, electromagnetic brakes may not fully release, leading …
Read moreDisc brakes vs drum brakes for overhead and gantry cranes—what’s better?
Both disc brakes and drum brakes are widely used on overhead and gantry cranes, and “better” depends on the duty profile and environment. Disc brakes …
Read moreAre travel brakes and storm brakes the same on gantry cranes?
No. A travel brake is designed to control motion during normal operation—accelerating, decelerating, and stopping the crane along its rails. It’s …
Read moreWhat’s the difference between a service brake and a holding (parking) brake on cranes?
A service brake is used to slow or stop motion during normal operation (dynamic braking). It must dissipate heat, provide stable deceleration, and …
Read moreHow can I extend the service life of industrial brakes while maintaining safety?
Extending brake life is about reducing unnecessary heat and ensuring consistent, correct operation. Start with proper selection: size for both torque …
