Introduction to the Characteristics, Application Scope, and Operating Rules of Explosion-Proof Lever Hoist Products

1. Characteristics

Explosion-Proof Design: The explosion-proof lever hoist is constructed with an explosion-proof enclosure and non-sparking materials, such as copper alloys or stainless steel, to prevent ignition of flammable gases, vapors, or dusts. It meets international standards like ATEX, IECEx, or NEC, ensuring suitability for specific hazardous zones.

Robust Construction: Made from high-strength, corrosion-resistant materials, the hoist is designed to withstand harsh environments, including extreme temperatures and chemical exposure.

Mechanical Reliability: Features a manual lever mechanism for precise control, eliminating the need for electrical power. It includes a self-locking brake to secure the load and overload protection to prevent equipment failure.

Safety Features: Equipped with a load hook with a safety latch, non-sparking components, and optional limit switches to prevent over-travel, enhancing operational safety.

Ease of Use and Maintenance: Portable and lightweight, the hoist is easy to transport and position. It requires minimal maintenance, reducing downtime and operational costs.

2. Application Scope

Oil and Gas Industry: Used in refineries, drilling platforms, and storage facilities for maintenance and lifting operations in explosive environments.

Chemical and Pharmaceutical Plants: Ideal for handling materials where flammable chemicals or dusts are present.

Mining: Suitable for underground operations where explosive gases or dusts may be encountered.

Food Processing: Used in areas where dust explosions are a concern, such as grain silos or flour mills.

Military and Defense: Employed in environments where explosive materials are handled or stored.

3. Operating Rules

Pre-Use Inspection:

Check the exterior for damage, corrosion, or loose parts.

Inspect the load chain for wear, elongation, or twisted links.

Verify the functionality of the brake, overload protection, and safety latch.

Ensure the explosion-proof certification labels are intact and valid.

Environmental Check:

Confirm the hoist is suitable for the specific hazardous zone (e.g., Zone 1, Zone 2).

Ensure the operating temperature and environmental conditions match the hoist’s specifications.

Safe Operation:

Never exceed the rated load capacity of the hoist.

Ensure the load is properly secured and balanced before lifting.

Avoid sudden movements or jerks during lifting and lowering.

Keep the hoist away from heat sources, open flames, or other ignition hazards.

Maintenance and Storage:

Regularly lubricate moving parts according to the manufacturer’s recommendations.

Store the hoist in a dry, clean, and secure location when not in use.

Conduct periodic inspections and maintenance by qualified personnel.

Emergency Procedures:

In case of malfunction or abnormal operation, immediately stop using the hoist and isolate it from the load.

Follow established emergency procedures for handling hazardous materials or equipment.
