Folding stairs for loading platform are used to bridge the distance from loading racks to tank cars or rail tankers. They can also be used for other similar applications. The stairway features a carbon steel construction, complete with handrails, anti-skid steps, and spring cylinder balancing. The contact bracket is covered with oil-resistant rubber bumpers for safety. Its frame can be folded flat to occupy a smaller space when not assembled.

Regardless of the angle at which the ladder leans against the top of the tank truck, its movable steps always remain in a horizontal position. This provides operators with a stable and flat foothold, effectively preventing slips or missteps.
Anti-slip Treads: The steps typically feature a serrated grid or grating structure, providing excellent anti-slip performance even in rainy, snowy, or oily conditions.
Anti-collision Buffer Pads: Anti-collision buffer pads are installed where the ladder contacts the tank truck. This not only protects the tank body from scratches but also prevents sparks caused by metal-on-metal collisions, which is crucial in flammable and explosive environments.
Chain Protection: A safety chain or rope system is installed. Once the ladder is fully lowered, engaging the chain prevents the ladder from accidentally springing up or detaching, adding an extra layer of security for high-altitude work.
The overall structure is typically made of low-carbon steel, aluminum alloy, or stainless steel, and undergoes hot-dip galvanizing or zinc plating treatment. This gives the access ladder excellent corrosion and rust resistance, allowing it to withstand the harsh outdoor environments of the petrochemical industry and ensuring a long service life.
When not in use (stowed position), the access ladder can be folded up and retracted, sitting flush against the side of the loading gantry. It occupies minimal space and does not interfere with other operations or passage on the gantry.
The installation method is simple; it can be bolted to the loading gantry or directly welded. By selecting ladders with different numbers of steps (e.g., 3-step, 4-step, 5-step), it can meet the operational needs of tank trucks of varying heights and types.
To enhance packaging quality, strengthen packaging management, and prevent product loss or damage during transit resulting from packaging-related issues, this Export Packaging Specification has been specifically formulated.
This specification applies to the packaging of all products exported by this Company.
| Requirement | Responsible Dept. | |
| Before Packaging | Confirm that the product has been tested and is free of defects. Confirm that the product’s exterior is clean and free of stains, standing water, or similar issues. | Quality Dept. |
| Product Packaging | 1. Skid-mounted and Containerized Packaging: A three-layer packaging system—comprising inner, intermediate, and outer packaging—is required. The packaging must be securely fastened and stable, providing effective protection for the product. a. Individual instruments on the skid must be protected with bubble wrap and tightly bound with stretch film. b. The entire skid must be protected with bubble wrap and tightly bound with stretch film. . Containers equipped with racks must be securely fastened using strapping bands. d. Loose piping must be wrapped in protective fabric to prevent paint damage from impact, and then placed onto a dedicated packing rack. Legend 2. Individual Packaging A three-layer packaging system—comprising inner, intermediate, and outer packaging—is required. The packaging must be securely fastened and stable, providing effective protection for the product. Inner Packaging: Foam wrap must be used to fully enclose the items, ensuring that no direct collision or friction occurs between products or between the products and the carton. Each individual item must bear both Chinese and English labels to facilitate inventory verification by the customer. Intermediate Packaging: Packed in cartons. Outer Packaging: Wooden crate packaging. The materials used must consist of plywood crates (fumigation-free) reinforced with steel strips. Any remaining space inside the box must be filled with cushioning material. For heavier products, particular attention should be paid to packaging strength to prevent damage during transit. | Production Dept / Warehousing & Logistics Dept |
| packaging | 1. Steel strips / wide wooden slats to wrap the 8 legs. Note: Wooden slat width: mm; thickness: mm. 2. 6–8 reinforcement points inside the box. 3. For any face exceeding 2 CBM, cross-bar or I-beam steel reinforcement is required. Note: The spacing between cross-bars/I-beams must be less than or equal to mm. 4. All packaging must include forklift access points to facilitate loading and unloading. 5. Packaging must be designed based on the dimensions of the container; under no circumstances should it exceed the container’s length, width, or height. | Warehousing & Logistics Dept |
| Shipping Mark | In accordance with the accompanying documentation, affix the shipping marks and packing lists to the front and sides, respectively . | Warehousing & Logistics Dept |
| Packaging Markings | Fragile, Keep Dry, This Side Up. Labels must be clear and securely affixed. | Warehousing & Logistics Dept |
| Instruction Manual placement | You must include: an instruction manual (either entirely in English or bilingual English-Chinese), a Certificate of Conformity, and a test report. (Note: No documents may be submitted exclusively in Chinese.) | Quality Dept |
| Take photos for the archive. | The packaging process must be documented via photographs or video recordings, and relevant information retained. All photographic and video files must be date-stamped and subsequently archived. | Warehousing & Logistics Dept |
