FRP LADDER STEP TROLLEY

An FRP Ladder Step Trolley combines the functionality of a step ladder with the mobility of a trolley, offering ease of movement in workplaces. This type of equipment is typically used in environments where a portable ladder is required for quick access and where electrical insulation, corrosion resistance, and durability are important.

Here are the technical specifications for an FRP Ladder Step Trolley:

1. Material Composition:

• Frame Material:
  • Made of Fiber Reinforced Plastic (FRP), typically E-glass fiberglass combined with polyester or vinyl ester resin.
  • Non-conductive and corrosion-resistant.
• Rungs: Usually made of reinforced plastic or a combination of FRP and non-slip coating.
• Trolley Wheels: High-quality PVC or rubber wheels, designed for durability and easy mobility. These are often non-marking to prevent damage to floors.

2. Dimensions:

• Height: Varies, usually from 3 to 12 feet (0.9 to 3.7 meters), depending on the number of steps.
• Width: Typically between 18 to 24 inches (45 to 60 cm).
• Depth: About 12 to 18 inches (30 to 45 cm).
• Step Size: Each step usually has a width of 10 to 12 inches (25 to 30 cm) and depth of 8 to 10 inches (20 to 25 cm).

3. Load Capacity:

• Standard Load Capacity: Typically ranges between 250 lbs (113 kg) to 500 lbs (227 kg), depending on the design.
• Heavy Duty Models: Can support higher loads of 500 lbs (227 kg) or more, suited for industrial applications.

4. Rung Spacing:

• Standard rung spacing is 10 to 12 inches (25 to 30 cm), providing comfort and ease of use while climbing.

5. Safety Features:

• Slip-Resistant Rungs: The rungs often have a textured or non-slip surface (e.g., coated with grit or rubber) to reduce slipping risk.
• Handrails: Some models may include handrails for additional safety while ascending or descending the ladder.
• Trolley Locking Mechanism: Trolleys are often equipped with a locking mechanism to prevent accidental movement while in use.
• Non-Conductive: FRP ladders and step trolleys are non-conductive, making them suitable for electrical environments.

6. Wheels and Mobility:

• Wheel Size: Wheels usually range from 4 inches (10 cm) to 8 inches (20 cm) in diameter, ensuring smooth movement.
• Wheel Type: Often rubberized or polyurethane wheels that are designed for quiet, smooth rolling and are resistant to wear and tear.
• Caster Type: Swivel casters with brakes or locking mechanisms are common to prevent unwanted movement while in use.
• Weight Distribution: The wheels are designed to ensure balanced weight distribution, preventing the trolley from tipping over during use.

7. Strength and Durability:

• Flexural Strength: Typically 14,000 to 20,000 psi (96 to 138 MPa), ensuring the structure remains intact under stress.
• Corrosion Resistance: Ideal for use in wet, corrosive, or harsh environments like chemical plants, food processing areas, and outdoor spaces.
• Impact Resistance: The FRP construction provides high impact resistance, ensuring the trolley is durable over time even in rugged environments.

8. Environmental Resistance:

• UV Resistance: FRP is resistant to UV radiation, ensuring that the ladder trolley will not degrade or become brittle with exposure to sunlight.
• Weather Resistance: Resistant to rain, snow, and extreme temperatures, making it suitable for both indoor and outdoor use.
• Chemical Resistance: FRP is highly resistant to a variety of chemicals, including oils, solvents, and acids, which makes it ideal for industrial applications.

9. Temperature Range:

• Operating Temperature: Typically suitable for temperatures ranging from -40°F (-40°C) to 200°F (93°C), depending on the resin used.

10. Design Types:

• Fixed Step Trolley: Features fixed steps with wheels at the base, offering easy portability between workstations.
• Folding Step Trolley: Compact, collapsible design for storage in tight spaces when not in use.
• Mobile Step Trolley with Platform: Provides a larger standing platform at the top for enhanced stability while working.

11. Standards and Certifications:

• OSHA Compliant: Meets OSHA standards for ladder safety in the workplace.
• ANSI Standards: Follows ANSI A14.5 for ladder safety and usage.
• UL Listed (Optional): Some models may be UL certified, particularly those designed for electrical or hazardous environments.

12. Weight:

• Overall Weight: Depending on the size and load capacity, the weight of an FRP ladder step trolley can range from 15 to 70 kg.

13. Assembly:

• Pre-Assembled or Kit Form: Some models come pre-assembled, while others might be provided in a kit form for easier transport and cost-effectiveness.

14. Color:

• FRP step trolleys are often available in bright colors such as yellow, orange, or green for high visibility in workplace environments.

Summary:

FRP Ladder Step Trolleys are designed to offer a durable, safe, and portable solution for workplaces that require mobility, non-conductivity, and resistance to harsh conditions. These trolleys combine the mobility of wheels with the functional safety features of a ladder, making them ideal for warehouses, factories, and other industrial settings.

Before purchasing, it's essential to verify that the specific model meets industry requirements and safety standards for your intended application.
