In modern industrial environments, the electric chain hoist stands out for its reliability and compact design. Particularly, the trolley-type electric chain hoist simplifies maintenance and parts replacement, offering superior ease of use compared to other configurations. This article explores the core features of standard hoists and clarifies when your operation requires the specialized protection of an explosion-proof model.

Core Features of Modern Electric Chain Hoists

1. Weather-Resistant Controls

The handheld pendant controller features IP54+ ingress protection, ensuring reliable performance in damp or dusty environments—eliminating delays due to moisture.

2. Alloy Steel Load Sheave

Crafted from high-grade alloy steel with specialized heat treatment for longevity. Optimized guidance ensures smooth chain engagement and minimizes friction.

3. Low-Voltage Safety

Utilizes 24V–48V control circuits for the pendant, drastically reducing electrocution risks and aligning with IEC 60204-1 safety standards.

4. Compact Architecture

Close-coupled structural design minimizes headroom requirements, allowing for maximum lifting height in facilities with low ceiling clearance.

Explosion-Proof vs. Standard Electric Chain Hoists

While sharing a basic category, explosion-proof hoists are engineered specifically for hazardous environments where sparks could trigger catastrophic events.

Feature	Standard Electric Hoist	Explosion-Proof (Ex) Hoist
Primary Purpose	General industrial lifting	Safe operation in hazardous locations
Ignition Prevention	Standard design	Eliminates sparks/arcs capable of igniting flammable atmospheres
Motor Design	Conventional induction motor	Flameproof disc-brake motor with robust thermal management
Temperature Control	Standard operation	Certified Surface Temp Class (e.g., T4 ≤135°C) to prevent auto-ignition

High-Performance Explosion-Proof Motors

Our explosion-proof motors support various lift speeds and feature high-strength hoisting chains. The specialized anti-explosion treatment allows the equipment to adapt to flammable, explosive, and high-dust working environments safely.

Certification Standards

Explosion-proof equipment must comply with rigorous international safety frameworks. Our products align with:

GB 3836.1: Electrical equipment for explosive gas atmospheres (Aligned with IEC 60079).
GB 12476.1: Protection against ignition of combustible dust.
Ratings: DIIBT4, DIICT4, and DIPA20TAT4 certifications for various hazardous mixtures.
