A reliable brake is essential for the safe operation of any electric hoist. When the brake fails to hold the load properly, it can cause load drifting, inaccurate positioning, unexpected downtime, and even serious safety risks.
Fortunately, most brake failures can be prevented with proper maintenance and correct operation.
Brake friction materials wear over time. As they become thinner, the brake loses holding force and may allow the load to drift.
Solution: Inspect the brake regularly and replace worn components before they reach their service limit.
Oil leaking from the gearbox or bearings can reduce friction between the brake surfaces, causing slipping under load.
Solution: Repair the leak immediately and clean or replace contaminated brake parts.
An improperly adjusted brake air gap may prevent the brake from engaging or releasing correctly.
Solution: Check and adjust the brake according to the manufacturer's maintenance instructions.
Lifting loads beyond the hoist's rated capacity increases wear on both the motor and the braking system.
Solution: Always operate within the rated load and use overload protection whenever possible.
Frequent lifting cycles or continuous heavy-duty operation can overheat the brake, reducing its performance and shortening its lifespan.
Solution: Choose a hoist with the appropriate duty rating and allow sufficient cooling during intensive operation.
Low voltage, damaged wiring, or faulty brake coils can prevent an electromagnetic brake from operating correctly.
Solution: Inspect the power supply and electrical components regularly, replacing damaged parts when necessary.
Many brake problems result from neglected inspections. Dust, vibration, and normal wear gradually reduce braking performance over time.
A simple maintenance routine—including checking brake wear, cleaning components, and testing holding capacity—can significantly improve reliability and reduce unexpected downtime.
Brake failure is rarely sudden. In most cases, it develops gradually due to wear, contamination, overloading, incorrect adjustment, or lack of maintenance. Routine maintenance is important, but brake reliability also depends on the quality of the hoist itself.
At Vertex, our electric chain hoists are equipped with a fail-safe electromagnetic braking system that automatically engages when power is cut, helping keep suspended loads securely in place. Every hoist is tested before shipment to ensure stable braking performance and dependable operation.
For customers operating in regions with unstable power supplies, we also offer wide-voltage electric chain hoists (205–480V), reducing the risk of voltage-related issues while simplifying inventory management.
