DYW630-1900 Series Explosion Protected Electro-hydraulic Drum Brakes

DYW630‑1900 series are normally closed, explosion‑protected electro‑hydraulic drum brakes with high braking torque, specially designed for hazardous environments with flammable gas, vapor or dust. They are widely used in explosion‑proof hoisting, conveying and mining machinery.

Basic Identification

Model: DYW630‑1900 series

Type: Explosion‑protected electro‑hydraulic drum brake

Brake drum diameter: 630 mm

Rated braking torque: 1900 Nm

Actuation: Explosion‑proof electro‑hydraulic thruster

Application: Braking, stopping and safety holding in explosive hazardous areas

Key Features

Explosion‑proof structure suitable for Ex d II CT4, DIP A21 TA,T4 and other hazardous locations

Normally closed fail‑safe design: automatically brakes when power fails

High braking torque, stable and reliable performance

Asbestos‑free friction linings, long service life

Adjustable braking torque and shoe clearance

Compact structure, easy installation and maintenance

Suitable for frequent operation in harsh environments

Working Principle

Brake state (power off):Powerful built‑in springs press the brake shoes against the drum, providing braking force.

Release state (power on):The explosion‑proof electro‑hydraulic thruster lifts the brake arms to release the brake.

In case of power failure or emergency, the brake engages immediately to ensure safety.

Typical Applications

Explosion‑proof cranes, hoists and winches

Coal mines, oil fields, chemical and gas industries

Port and metallurgical machinery in explosive hazardous environments

Conveying systems requiring explosion‑proof braking

Short version 

DYW630‑1900 series explosion‑protected electro‑hydraulic drum brakes are high‑torque, fail‑safe brakes designed for explosive hazardous environments, with 630 mm drum diameter and 1900 Nm rated torque.
