DLZ25 Series Power-driven Wheel Brakes

🛠️ Product Overview: DLZ Series Electromagnetic Wheel Brake

The DLZ Series is designed for fail-safe (safety braking) applications, primarily used on cranes, hoists, and port machinery to prevent movement during power outages or emergencies.

Model Correlation: DLZ Series (Electromagnetic Fail-Safe Brake).

Type: Electromagnetic / Spring-Applied (Fail-Safe).

Action:

Braking (Power Off): A powerful spring forces the brake shoe against the wheel or rail.

Release (Power On): An electromagnetic coil is energized to pull the armature and release the brake.

Key Feature: "Fail-Safe" Operation. If power is lost, the brake automatically engages to hold the load in place.

✨ Key Features

High Safety Factor: Designed specifically for safety-critical applications. The spring-applied mechanism ensures braking even during power failures.

Energy Efficient: Many models use a "High-Low Current Control" system. They use a high current to initially release the brake and then switch to a low holding current, reducing heat generation and energy consumption.

Robust Construction: Built with cast iron or steel components to withstand impacts and harsh industrial environments (dust, moisture, vibration).

Manual Release: Equipped with a manual release lever or screw for maintenance or emergency operation when power is unavailable.

Wear Compensation: Features automatic or manual adjustment mechanisms to compensate for brake shoe wear, ensuring consistent braking performance.

🏭 Typical Applications

The DLZ series is widely used in:

Overhead Cranes & Hoists: For bridge, trolley, and hoist mechanisms.

Port Machinery: Rubber-tired gantry cranes and ship unloaders.

Elevators & Lifts: For emergency braking and holding.

Mining Equipment: Conveyor brakes and winches.

💡 Maintenance & Operation Tips

Air Gap Check: Regularly inspect the gap between the armature and the electromagnet. If the gap is too large (due to wear), the electromagnetic force may not be sufficient to release the brake.

Coil Health: Inspect the electromagnetic coil for signs of burning or overheating, especially if the brake is chattering (vibrating).

Lining Wear: Monitor the thickness of the friction linings. Replace them before they wear down to the metal backing to avoid damaging the wheel or rail.

Manual Release: Ensure the manual release mechanism is not obstructed, as it is crucial for maintenance safety.
