Question

What explosion-proof grades do your electric hoists meet?

Our hoists strictly comply with international explosion-proof standards, offering grades such as Exd IIB T4 and Exd IIC T4. They are certified for safe operation in explosive gas and dust environments, ensuring maximum safety in hazardous zones.

How can I quickly order spare parts after the warranty expires?

We maintain a complete inventory of standard spare parts for all our models. You can contact us via WhatsApp or email at any time, and we will dispatch the required parts via express air freight (DHL/FedEx) to minimize your downtime.

How do you handle installation and technical support for overseas buyers?

We provide comprehensive English installation manuals, detailed electrical schematics, and video guidance. For complex projects, our engineers are available for 24/7 online technical support to guide your local team through installation and commissioning.

What is the lifting capacity range of your explosion-proof hoists?

We manufacture a wide range of capacities, typically from 0.5 tons up to 30 tons or more. Whether you need light-duty material handling or heavy-duty industrial lifting, we can provide the exact tonnage required for your project.

What specific anti-spark materials are used in your equipment?

To prevent mechanical sparks, critical friction components (like hooks and running wheels) are crafted from high-quality aluminum bronze or beryllium bronze. The hoist motors and electrical enclosures are also strictly explosion-proof.

What industrial environments are your hoists suitable for?

Our explosion-proof hoists are specifically engineered for hazardous environments, including petrochemical plants, coal mines, oil and gas refineries, pharmaceutical manufacturing, and offshore drilling platforms.

What is the difference between your explosion-proof wire rope hoists and chain hoists?

Wire rope hoists are ideal for heavy loads, high lifting heights, and continuous heavy-duty operations. Chain hoists are more compact, cost-effective, and perfect for lighter loads or confined spaces with limited headroom.

Can you customize the hoist according to our site drawings and specifications?

Absolutely. We specialize in non-standard customization. Simply provide your CAD drawings, clearance requirements, or specific working conditions, and our engineering team will design a tailored lifting solution for your facility.

Can the voltage and frequency be customized for my country?

Yes, we can configure the motors and electrical systems to match your local industrial power supply, including 220V, 380V, 415V, 440V, or 480V at 50Hz or 60Hz, 3-phase.

Do you provide dual-speed lifting options?

Yes, we offer both single-speed and dual-speed configurations. Dual-speed hoists provide a slow speed for precise positioning of sensitive materials and a normal speed for efficient handling.
