Explosion proof electric hoist ATEX certified

Electric hoist explosion-proof housing, precision electrical components, and advanced lifting mechanism ensure maximum safety, reliability, and efficiency even in harsh working conditions.

Detailed Product Features

1. Explosion-Proof Design

• Enclosures: Motor, control box, and electrical components are sealed with flameproof enclosures (Ex d) to prevent ignition of external atmosphere.

• Cable & Wiring: Explosion-proof cable glands and armored cables prevent sparks and mechanical damage.

• Surface Temperature Control: Designed to maintain surface temperature below ignition point of hazardous gases/dust.

2. High-Performance Lifting System

• Motor: Explosion-proof lifting motor with insulation Class F, protection grade IP65, and S4 duty cycle for frequent start/stop operations.

• Gearbox: Precision-hardened gears with lifetime lubrication for smooth, low-noise operation.

• Braking: Electromagnetic disc brake with automatic load holding, even during power failure.

3. Robust Mechanical Construction

• Frame: Heavy-duty steel construction with epoxy powder coating for corrosion resistance.

• Wire Rope / Chain: High-strength galvanized wire rope or Grade 80 alloy steel load chain for long service life.

• Hooks: Forged carbon steel hooks with 360° swivel and safety latch.

4. Advanced Safety Features

• Overload limiter with automatic power cut-off.

• Upper and lower travel limit switches.

• Thermal motor protection.

• Emergency stop button on pendant or remote control.
