In industries where flammable gases, vapors, or dust are present, a standard hoist can be a major fire hazard. A single spark from a motor or a friction-generated heat spot could lead to a catastrophe. This is where an explosion-proof electric hoist becomes essential.

At GT Winch, we manufacture specialized lifting equipment designed to operate safely in Zone 1, Zone 2, Zone 21, and Zone 22 environments. Our hoists prevent ignition through advanced engineering and spark-resistant materials.

A GT explosion-proof electric hoist is not just a standard hoist with a cover. It features several critical safety modifications:

1. Flameproof Enclosures: The motor and electrical control box are housed in heavy-duty, flameproof casings that contain any internal spark.

2. Spark-Resistant Materials: We use copper-plated or stainless steel hooks and bronze-coated wheels to prevent friction sparks.

3. Overheating Protection: Specialized thermal sensors monitor the motor temperature to ensure it never reaches the auto-ignition temperature of the surrounding gases.

4. Static Prevention: All components are properly grounded, and we use anti-static materials for the pendant control and cables.

Our explosion-proof electric hoists are the trusted choice for several high-risk sectors:

In facilities where volatile chemicals are processed, our hoists are used to lift heavy drums, valves, and maintenance equipment safely.

From offshore platforms to onshore refineries, our equipment handles the heavy lifting where flammable vapors are a constant presence.

Whether it is methane gas in a mine or combustible dust in a grain silo, our hoists provide the necessary protection to prevent dust explosions.

When purchasing an explosion-proof electric hoist, understanding the certification is vital. GT Winch complies with major international standards:

• Ex d (Flameproof): Prevents an internal explosion from igniting the external atmosphere.

• Ex e (Increased Safety): Minimizes the possibility of excessive temperatures and sparks.

• Temp Classes: Our hoists are rated from T1 to T4, ensuring compatibility with various gas groups.

Zone 1 refers to an area where explosive gas is likely to occur in normal operation, requiring higher protection. Zone 2 is where explosive gas is not likely to occur, but if it does, it will only exist for a short time. We offer explosion-proof electric hoists for both zones.

Yes, you can, but it is not cost-effective. These hoists are more expensive due to the specialized materials and certifications. They are specifically built for hazardous areas.

Yes. We offer specific models designed for “Dust Ignition Protection” (Ex t), which are perfect for grain silos, flour mills, and carbon processing plants.

Absolutely. We provide both Chain Hoist and Wire Rope Hoist models in explosion-proof configurations.

Due to the high-risk environment, we recommend a formal safety inspection every 6 months to ensure that all flameproof seals and grounding components are intact.
