Introduction to the Use of Explosion-Proof Manual Trolleys

Explosion-proof manual trolleys are essential equipment designed for safe material handling in hazardous environments where flammable or explosive substances are present. This guide provides an overview of their uses, key features, operational steps, safety precautions, and maintenance practices.

1. Uses and Applications

Explosion-proof manual trolleys are primarily used in industries where safety is paramount, such as:

Petroleum and Chemical Plants: For transporting chemicals, raw materials, and finished products without generating sparks.

Mining and Gas Extraction: Safe handling of equipment in underground mines and gas fields.

Power Generation and Metallurgy: Moving heavy components in power plants and metallurgical facilities.

Pharmaceutical and Aerospace: Ensuring clean and safe environments during material handling.

They are often used in conjunction with explosion-proof manual chain hoists to lift and move loads safely.

2. Key Features

Spark-Free Design: Constructed from non-ferrous materials (e.g., copper alloy) to prevent sparks during operation.

Adjustable Wheelbase: Wheels can be adjusted to fit different rail widths, ensuring stability on various tracks.

High Load Capacity: Available in load capacities ranging from 0.5 to 20 tons.

Durable Construction: Designed to withstand harsh industrial environments.

3. Operational Steps

Before Use:

Inspection: Check the trolley for any damage, ensuring all components (wheels, brakes, hooks) are in good working condition.

Personal Protective Equipment (PPE): Wear safety helmets, gloves, and non-sparking footwear.

Environment Check: Ensure the work area is clear of obstacles and hazards.

During Operation:

Loading: Secure the load evenly on the trolley to avoid tipping.

Movement: Push or pull the trolley slowly, especially on ramps or uneven surfaces.

Communication: Use hand signals or radios to communicate with nearby workers.

After Use:

Unload: Remove the load carefully and store the trolley in a designated area.

Clean: Wipe down the trolley to remove any debris or contaminants.

4. Safety Precautions

Training: Operators must receive proper training on the use of explosion-proof equipment.

No Modifications: Do not alter the trolley’s design or components without manufacturer approval.

Fire Safety: Keep fire extinguishers nearby and ensure all personnel know their locations.

Avoid Overloading: Never exceed the trolley’s maximum load capacity.

5. Maintenance and Care

Regular Inspections: Check for wear and tear on wheels, bearings, and brakes.

Lubrication: Apply lubricant to moving parts as recommended by the manufacturer.

Cleaning: Remove dirt and debris to prevent corrosion.

Storage: Store the trolley in a dry, cool place away from direct sunlight and moisture.

6. Troubleshooting

Difficulty Moving: Check for debris in wheels or excessive load.

Brake Issues: Ensure brakes are properly adjusted and lubricated.

Sparking: Replace any worn parts immediately and report the issue to supervisors.
