What 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 …
Read moreWhy must the hoisting mechanism use a fail-safe brake?
A hoist is a gravity-loaded system: if power is lost, the load will try to move in the unsafe direction (down). That’s why the hoisting mechanism …
Read moreWhat spare parts should I keep in stock for critical brake systems?
For safety-critical machines, downtime and risk are both expensive. Keep a minimum spare set of wear items and high-failure-risk components. Typically …
Read moreWhat installation mistakes most commonly cause brake problems?
Common installation errors include misalignment between brake and disc/drum, incorrect air gap or shoe clearance, improper mounting bolt torque, and …
Read moreWhich mechanisms on an overhead or gantry crane must have brakes?
On an overhead crane or gantry crane, brakes are typically required anywhere uncontrolled motion could create a safety hazard, damage equipment, or …
Read moreHow do I choose brake size based on disc diameter or drum size?
Disc diameter and drum size directly influence torque capacity because torque equals friction force multiplied by effective radius. A larger disc or …
Read moreWhat is the role of a brake power supply box (e.g., DKZ)?
A brake power supply box provides the correct electrical power and control interface for electromagnetic brake coils or related brake components. In …
Read moreHow do I choose the correct hydraulic power unit (HPU) for a brake system?
Selecting an HPU starts with the brake’s required release pressure and flow. You must provide enough pressure to overcome spring force and enough flow …
