Introducing the Intelligent Sensor Fork

Revolutionizing Forklift Safety and Efficiency

Say goodbye to relying on intuition when your view is blocked by transported goods. The  Smart Forklift is here to change the game! This innovative product combines an integrated camera and sensor technology to provide forklift drivers with enhanced safety and reduced damage in their daily operations.

With the Smart Forklift, you can enjoy a clearer view of your surroundings, even when your line of sight is obstructed. This cutting-edge technology is designed to make your work easier, safer, and more efficient. 

Enhancing Logistics Safety with Smart Technology

A Step Towards a Safer Future

The logistics industry is poised for a significant transformation, with a major focus on improving safety standards. However, there is still much work to be done to achieve this goal.

The Alarming Reality of Forklift Accidents

• Between 35,000 and 62,000 injuries involving forklifts occur every year

• 34,900 forklift accidents result in serious injuries annually

• 61,800 non-serious injuries related to forklift accidents occur each year

• 78 fatalities occurred due to forklift accidents in 2020

The average cost of a serious accident is approximately $41,003 in workers' compensation claims, and the total cost of forklift accidents can be substantial, with some estimates suggesting an average cost of $188,000 per serious accident.

The Root Cause of Accidents

Human error is the primary cause of accidents, often resulting from forklift drivers operating with limited visibility. The Smart Forklift is designed to support drivers by providing:

• A better view of their surroundings

• Warning functions to alert them of potential hazards

• Improved visibility to reduce blind spots

• Intelligent sensors to enhance overall safety

• Statistics of Occupation Health and Safety Administration (up to 2024)

• Industrial Truck Association (latest available data)

Additional Considerations

• Safety Standards: Ensure compliance with safety standards like ISO 3691 for industrial trucks.

• Environment Handling: Use ruggedized hardware to handle extreme temperatures, dust, and vibrations.

• Power Optimization: Optimize sensor and controller power usage to prevent draining the forklift’s battery.

Yes, integrating RFID-based inventory tracking into the smart forklift system is a great addition. This can enhance both operational efficiency and inventory management. Here's how RFID integration can be achieved:

---

RFID-Based Inventory Tracking in Smart Forklift

1. How it Works

• RFID Tags: Each inventory item is equipped with an RFID tag containing unique identification data (e.g., SKU, item name, location).

• RFID Reader on Forklift: An RFID reader is mounted on the forklift to scan tags as the forklift interacts with inventory.

• Data Transmission: Scanned data is transmitted to a centralized system via the forklift’s IoT module.

• Real-Time Updates: The system updates inventory records in real time, providing insights into item location, stock levels, and movement history.

---

2. Benefits of RFID Integration

• Accurate Inventory Tracking: Minimizes manual errors by automatically identifying and logging inventory items.

• Faster Operations: Reduces time spent on manual scanning or inventory counting.

• Improved Workflow: Streamlines warehouse operations by combining inventory management with forklift movement.

• Enhanced Safety: Prevents picking errors and ensures the correct items are moved to the right locations.

• Real-Time Visibility: Provides instant access to inventory data for better decision-making.

---

5. Example Use Case

1. Scenario: A forklift operator is tasked with picking and moving pallets in a warehouse.

2. Process:

• The forklift approaches the pallet.

• The RFID reader scans the tags on the pallet.

• The system verifies the item against the task assigned.

• If correct, the system logs the movement and updates the inventory database in real time.

• If incorrect, an alert is sent to the operator.

This addition not only enhances the functionality of the smart forklift but also positions the solution as a comprehensive warehouse automation system.
