2 Ton Explosion-Proof Electric Chain Hoist Case Study – Pakistan

Case Study: 2-Ton Explosion-Proof Electric Chain HoistSupplied to a Buyer in Pakistan

Background of the Project

Buyer Situation

A steel-processing workshop in Pakistan contacted us with a straightforward problem. Their lifting work takes place in a Zone 1 hazardous area, where dust and flammable vapors appear from time to time. Their old manual chain blocks were slow, tiring, and increasingly unsafe for this environment.

• Daily lifting involved repeated 2-ton loads.
• Manual tools slowed production and increased operator fatigue.
• The workspace required equipment that would not spark, even under harsh conditions.

What the Buyer Needed

The workshop wanted a compact 2-ton explosion-proof electric chain hoist that could run smoothly in a dusty, semi-hazardous environment. They weren’t looking for anything complicated—just a dependable tool that could replace their manual hoists.

• Compact size for low headroom.
• Explosion-proof protection suitable for Zone
• Full electric operation for faster, safer lifting.

Challenges Identified

During the initial review, several issues became clear. Some were related to safety; others were tied to daily workflow.

• Manual hoists caused delays and inconsistent lifting.
• Dust buildup increased the risk of equipment overheating.
• Non-rated equipment was not acceptable in a semi-hazardous zone.
• Operators struggled with heavy loads, raising safety concerns.

Why Safety and Reliability Became the Focus

The buyer needed equipment that could run every day without risking ignition or frequent breakdowns. Their priority was simple: keep workers safe and production steady.

• Explosion-proof certification was mandatory.
• Reliability mattered because downtime would disrupt the entire workshop.
• Easy maintenance was important due to limited onsite technicians.

Summary

In short, the workshop needed a safe, reliable, and compact 2-ton explosion-proof electric chain hoist designed for a Zone 1 environment. The goal was to replace outdated manual tools and ensure stable daily lifting without compromising safety.

• Hazardous environment: Zone 1
• Required capacity: 2 tons
• Main goals: safety, stability, practical daily use
• Core buyer need: certified explosion-proof electric chain hoist

Buyer Requirements

What the Buyer Needed from the Start

In the first round of discussions, the customer outlined a clear set of technical and practical needs. Their workshop handles repeated lifting tasks every day, so the hoist had to match both the working conditions and the available space.

Key Technical Requirements

The buyer listed several must-have specifications to ensure the hoist would operate safely and efficiently in their Zone 1 environment.

• Load Capacity: 2 tons for routine lifting tasks.
• Lifting Height: 4 meters to cover their full working area.
• Power Supply: 380V / 50Hz / 3-phase, the standard setup across most industrial sites in Pakistan.
• Explosion-Proof Grade: BT4, suitable for workshops where flammable gases or vapors may appear.
• Compact Structure: Needed to work within tight headroom without modifying the existing building.
• Low Maintenance: Important because onsite technicians have limited time and resources for frequent repairs.

Operational Expectations

Beyond the numbers, the buyer wanted equipment that could be trusted day after day. They needed a hoist that was:

• Durable enough for continuous use
• Easy for operators to handle
• Fully compliant with international safety and explosion-proof standards

Proposed Solution: Explosion-Proof Electric Chain Hoist

Recommended Model

After reviewing the site conditions and the buyer’s daily workload, we proposed the WBH-02001SE explosion-proof electric chain hoist (Identification No. 250602001).
This model fits the load requirements, matches the workshop’s power supply, and meets the explosion-proof level needed for Zone 1 operations.

Key Technical Specifications

The hoist was configured to match the customer’s exact working environment and provide stable day-to-day performance.

• Rated Load Capacity: 2 t
• Lifting Height: 4 m
• Lifting Speed: 6.6 m/min
• Traveling Speed: 11 m/min
• Motor Power: 3 kW
• Rated Current: 7.8 A
• Working Voltage: 380 V / 50 Hz / 3-phase
• Insulation Class: F
• Duty Class: M4, suitable for regular lifting cycles across a full shift
• Explosion-Proof Grade: BT4
• Inspection Date: June 2025

Why This Model Was a Good Fit

This configuration provided a balance of safety, durability, and ease of use.
The M4 duty class supports frequent lifting, and the BT4 explosion-proof grade ensures safe operation in areas where flammable gases or dust may appear.

Why This Model Fit the Customer Perfectly

The explosion proof elecric hoist met all the buyer’s key needs, combining safety, efficiency, and reliability in a compact package.

• Explosion-Proof BT4: All electrical components are fully sealed to prevent sparks in hazardous areas.
• Stable Lifting: 6.6 m/min speed ensures smooth and efficient material handling.
• Durable Duty Class: M4 rating provides higher longevity than standard light-duty hoists.
• Reliable Motor: 3 kW power delivers consistent torque, even during long shifts.
• Compact Design: Fits easily into tight headroom without requiring structural modifications.

This combination ensured the buyer received a practical, safe, and reliable solution for daily lifting tasks.

Implementation and Delivery

Production and Testing

After the buyer approved the technical drawings, production of the WBH-02001SE began and was completed on schedule. Before shipment, every unit underwent thorough testing to ensure safety and reliability.

• Full-load test to verify lifting performance
• Motor heating test to prevent overheating during long shifts
• Insulation and grounding check for electrical safety
• Explosion-proof enclosure inspection to confirm BT4 compliance
• Visual inspection to meet CE/ISO standards

Documentation and Shipment

The hoist was shipped to Pakistan with all necessary documents to support installation, operation, and compliance.

• Factory test report
• Explosion-proof certification
• Electrical schematic
• Installation and maintenance guide

This ensured the customer could install and operate the hoist safely, with full confidence in its performance and compliance.

Results After Commissioning

Performance Outcomes

Once the WBH-02001SE was installed, the buyer immediately noticed improvements in daily operations. The hoist delivered stable, reliable lifting, even in dusty conditions common to their workshop.

• Stable Lifting: Smooth performance under repetitive loads
• Reduced Downtime: Lower failure rate than the previous electric hoist
• Increased Efficiency: Faster handling of daily material
• Enhanced Safety: BT4-rated explosion-proof protection gave operators peace of mind

Operator Feedback

The workshop team quickly adapted to the new hoist. Intuitive controls and consistent running speed made daily operation straightforward and safe, reducing operator fatigue and mistakes.

Buyer Takeaways

Key Considerations for New Buyers

When selecting an explosion-proof electric hoist for hazardous workshops—whether in Pakistan or similar environments—pay attention to these critical points:

• Match Explosion-Proof Grade: Ensure the hoist’s rating (e.g., BT4) fits your facility’s zone classification.
• Power Compatibility: Confirm voltage and phase—380V/50Hz/3P is common in Pakistan.
• Duty Class: Choose M4 or higher if the hoist will be used frequently.
• Verify Documentation: Always check test reports and explosion-proof certificates before shipment.
• Space & Headroom: Ensure the hoist fits within your existing structure, especially in older buildings.

Practical Benefits

Selecting the right explosion-proof hoist improves safety, reduces downtime, and lowers maintenance needs—helping operators work efficiently without unnecessary risk.

Conclusion

The 2-ton WBH-02001SE explosion-proof electric chain hoist demonstrates how the right model can enhance both safety and productivity in hazardous workshop environments.

For buyers looking for explosion-proof lifting solutions, choosing equipment with the correct capacity, duty class, and BT4 protection ensures long-term reliability, smooth daily operation, and peace of mind for both management and operators.
