YPI -500-400X30 Electro-hydraulic Disc Brakes

⚙️ Product Overview

The YPI-500-400X30 is a heavy-duty Electro-hydraulic Disc Brake designed for industrial applications requiring high braking torque and precise control. It is a "spring-applied, hydraulically released" fail-safe brake, meaning it engages automatically when power is cut to ensure safety.

The model number breakdown typically indicates:

YPI: The series designation (often indicating a specific design generation or "Industrial" class).

500: The nominal braking torque rating, approximately 5000 N·m (500 daN·m).

400: The compatible Brake Disc Diameter of 400 mm.

30: The Brake Disc Thickness of 30 mm.

💡 Key Features & Characteristics

High Torque Capacity:
Rated for approximately 5000 N·m, this brake is designed for mid-to-heavy range industrial loads, offering a balance between compact size and high stopping power.

Automatic Compensation:
Like modern YP series brakes, the YPI typically features a non-step (stepless) lining wear compensation device. This ensures the brake gap remains constant as the pads wear, maintaining consistent braking performance without manual adjustment.

Electro-hydraulic Actuation:
Powered by an electro-hydraulic thruster (likely an Ed-series thruster sized for this torque), it provides smooth braking action and fast response times.

Interlocked Equalization:
The mechanism ensures that the brake pads retract evenly from the disc on both sides, preventing "drag" (rubbing) when the brake is released and ensuring uniform pad wear.

Safety & Monitoring:

Fail-Safe: Springs apply the brake; electricity releases it.

Limit Switches: Can be equipped with limit switches to signal "Brake Open" or "Lining Worn" status to the main control system (PLC).

Manual Release:
Equipped with a manual release lever or screw to open the brake for maintenance or emergency movement when power is unavailable.

🏭 Typical Applications

This brake is widely used in material handling and heavy industry:

Cranes: Hoisting and travel mechanisms for overhead and gantry cranes.

Conveyors: Belt conveyors in mining and power plants.

Port Machinery: Ship unloaders and stacker-reclaimers.

Metallurgy: Auxiliary drives in steel mills.

📋 General Technical Specifications

Note: The "YPI" prefix is often a variation of the standard "YP" series (such as YP1/YP2/YP3). While the standard YP1 series typically maxes out around 1750 N·m, the "500" designation in this model implies a higher torque variant or a specific manufacturer's classification (where 500 = 5000 N·m). Always verify the exact torque curve with the specific manufacturer's datasheet.
