What are the core functions of the movable ladder with guardrails that is used in conjunction with loading arms during automotive oil loading and unloading processes?

The movable ladder with guardrails, also referred to as the "oil loading and unloading operation ladder," is an essential safety auxiliary equipment in automotive oil handling scenarios, with core functions centered on operator safety and operational efficiency:
Provides a safe access path: Enables operators to climb from the ground to the loading/unloading port on the top of the fuel tank truck. The guardrails (usually including side handrails and a middle protective rail) prevent accidental falls, effectively mitigating safety risks caused by the 2-3 meter height difference between the tank top and the ground.
Adapts to operational postures and offers protection: The ladder can adjust its angle or length (some are telescopic or foldable) to fit the top surface of the fuel tank truck. It is equipped with non-slip pedals for stable standing, and the guardrails can block unexpected collisions, avoiding imbalance due to slight vehicle sway during operations.
Meets explosion-proof safety requirements: Made of aluminum alloy or carbon steel (undergoing anti-static treatment), the ladder prevents static sparks generated by friction, complying with explosion-proof specifications for oil loading and unloading scenarios and eliminating the risk of oil-gas explosions.
Enhances operational efficiency and standardization: The ladder is typically equipped with fixing devices (such as buckles and hooks) to secure it to the fuel tank truck or loading arm bracket, preventing displacement during operation. Some models come with a platform for placing tools and verifying documents, which aligns with the safe operating procedures for hazardous chemical loading and unloading (e.g., GB/T 18564-2019 "General Technical Conditions for Atmospheric Pressure Vessels (Tank Bodies) for Road Transport of Liquid Dangerous Goods").
Compatible with various vehicle models: The adjustable height design allows the ladder to adapt to the top height differences of fuel tank trucks of different tonnages (e.g., light trucks, heavy-duty trucks), ensuring a stable operating platform for oil loading and unloading operations across all vehicle types.
