In most cases, the floor of a truck or trailer body is elevated above ground level. Therefore, step ladders are required to assist operators when getting in and out of the cargo body. Step ladders are an essential functional component for box trucks, refrigerated trucks, trailers, and various special-purpose vehicles, improving accessibility, operating efficiency, and overall safety.
DESCRIPTION
Foldable Step Ladder Design
To balance safety, space efficiency, and durability, step ladders are commonly designed with a foldable structure, offering the following advantages.
Foldable and retractable
When not in use, the ladder can be folded inward or downward and stored neatly under the vehicle body or near the rear door.
Space-saving
Ideal for vehicles with limited chassis space, such as light-duty trucks, refrigerated trucks, and trailers.
Quick deployment
Simple operation allows fast unfolding and retraction.
Anti-slip safety features
The step surface is usually equipped with anti-slip patterns or rubber pads, ensuring safe use in wet or rainy conditions.
Materials for Step Ladders
Depending on vehicle type and operating conditions, step ladders are typically manufactured from the following materials.
Galvanized Steel
- High strength and excellent load-bearing capacity.
- Corrosion-resistant surface treatment, suitable for heavy-duty and high-frequency use.
Aluminum Alloy
- Lightweight design that helps reduce overall vehicle weight.
- Good corrosion resistance, ideal for refrigerated and food transport vehicles.
Stainless Steel
- Outstanding corrosion and weather resistance.
- Suitable for high-humidity, coastal, or industrial environments.
Composite Step Panels (Optional)
- Can be combined with FRP or rubber anti-slip surfaces.
- Enhanced grip and improved user comfort.
