Ensure it is close to the items to minimize lifting distance. 5. **Load Heavy Items First**: Start with the heaviest items, placing them at the bottom to create a stable base. This lowers the center of gravity and prevents tipping. 6. **Stack Items Securely**: Stack boxes or items in a crisscross pattern to distribute weight evenly. Ensure the load is balanced and not leaning to one side. 7. **Secure the Load**: Use straps, ropes, or bungee cords to secure the items to the dolly. This prevents shifting during transport. 8. **Check for Stability**: Gently rock the dolly to ensure the load is stable. Adjust as necessary to prevent tipping. 9. **Use Proper Lifting Techniques**: Bend your knees, keep your back straight, and lift with your legs when placing items onto the dolly. 10. **Transport Carefully**: Push the dolly forward, keeping it under control. Avoid sudden movements and be cautious on inclines or uneven surfaces. 11. **Unload Safely**: Once at the destination, carefully remove the securing straps and unload items, starting from the top.

General purpose dollies are typically made from a combination of materials to ensure durability, strength, and ease of use. The primary materials include: 1. **Steel**: Often used for the frame and structural components due to its strength and ability to support heavy loads. Steel dollies are robust and can handle rigorous use in industrial settings. 2. **Aluminum**: Chosen for its lightweight properties, aluminum is used in dollies where ease of maneuverability is important. It is also resistant to rust and corrosion, making it suitable for outdoor use. 3. **Wood**: Commonly used for the platform or base of the dolly, especially in furniture dollies. Hardwood like oak or maple provides a sturdy surface for carrying loads and is often used in combination with a steel frame. 4. **Plastic**: High-density polyethylene (HDPE) or other durable plastics are used for lightweight dollies. Plastic is resistant to moisture and chemicals, making it ideal for environments where exposure to such elements is a concern. 5. **Rubber**: Used for the wheels or casters, rubber provides traction and reduces noise during movement. It also helps in protecting floors from scratches and damage. 6. **Polyurethane**: Another material used for wheels, polyurethane offers a balance between durability and floor protection. It is resistant to wear and can handle heavier loads compared to rubber. These materials are often combined to create a dolly that meets specific needs, such as load capacity, environmental conditions, and ease of use.

To maintain and store a dolly effectively, follow these steps: 1. **Regular Inspection**: Frequently check for any signs of wear and tear, such as cracks, rust, or loose parts. Pay special attention to wheels, axles, and handles. 2. **Cleaning**: After each use, clean the dolly to remove dirt, debris, or any substances that could cause corrosion. Use a damp cloth for general cleaning and a mild detergent for stubborn stains. Ensure it is completely dry before storage to prevent rust. 3. **Lubrication**: Apply lubricant to moving parts like wheels and axles to ensure smooth operation. Use a suitable lubricant recommended by the manufacturer. 4. **Tightening and Repairs**: Regularly tighten any loose screws or bolts.
