Introduction to Explosion-Proof Electric Hoist Products

1. Characteristics

Explosion-Proof Design:

The explosion-proof electric hoist adopts special non-sparking materials for its exposed components, ensuring stable and reliable explosion-proof performance. It has passed explosion-proof performance tests by relevant authorities and obtained explosion-proof certificates.

Compact Structure and Lightweight:

The product features a compact structure, light weight, small volume, and large lifting capacity, making it suitable for indoor use in environments with explosive gas mixtures.

High Safety Standards:

Equipped with overload protection, limit switches, and emergency stop buttons, it ensures safe operation. The motor and control box are explosion-proof, with the motor having a built-in brake for quick stopping when power is cut.

Durable Components:

The hoist uses high-quality alloy steel chains and hooks, with the hook capable of free rotation and swing. The chain is driven by a limit spring to activate the limit switch, preventing accidents caused by over-lifting.

Modular Design:

The hoist is composed of several detachable parts, facilitating easy maintenance and shortening the inspection cycle. Components have high interchangeability, and the reducer uses standard modular cylindrical gears for convenient repairs.

2. Application Scale

Industries:

Explosion-proof electric hoists are widely used in industries such as chemicals, machinery, mining, docks, and warehouses where flammable and explosive gases or dust may be present.

Working Environments:

Suitable for indoor or outdoor environments with explosive gas mixtures (Zones 1 and 2) or explosive dust environments (Zones 21 and 22). The operating temperature range is typically -20°C to +40°C, with a relative humidity not exceeding 85% (at 25°C) and an altitude not exceeding 1000 meters.

Lifting Capacity:

Available in various models with lifting capacities ranging from 1 ton to 20 tons, meeting different lifting needs.

3. Operating Rules

Pre-Operation Inspection:

Check the workplace to ensure no obstacles in the lifting area.

Verify that the power supply is normal and that cables, switches, and sockets are secure.

Inspect the hook, chain, and other components for damage.

Ensure the operator is familiar with the equipment's performance, structure, and safety knowledge.

Safe Operation:

Operators must wear appropriate personal protective equipment (e.g., safety helmets, goggles, gloves).

Do not leave suspended loads unattended; ensure someone is nearby to observe and guide.

Follow the user manual and safety guidelines strictly; do not alter operating parameters without authorization.

Regularly inspect and maintain the hoist, promptly repairing or replacing any faulty parts.

Avoid working under suspended loads to prevent accidents from sudden descent.

Stay focused during operation; avoid distractions or delays.

Pay attention to the equipment's condition during operation and stop immediately if any abnormalities are detected.

Post-Operation Procedures:

Turn off the power and unplug the device after use to ensure it is in a safe state.

Clean and maintain the hoist regularly, storing it properly when not in use.

Emergency Handling:

Operators should be familiar with emergency procedures and escape routes.

In case of an accident or abnormality, report it immediately and cooperate with investigations.

For faulty or damaged equipment, promptly arrange for repairs or replacement; do not continue using it.
