Side-mounted Three-step Ladder
A dedicated safety access component for liquid hazardous chemical loading/unloading operations in the petroleum and chemical industries, specifically engineered for use with side-loading arms. It bridges fixed platform operations to tanker truck rooftops, resolving safe passage challenges for personnel during lateral loading scenarios.
Unlike fixed ladders, this foldable design features a parallel four-bar linkage mechanism and spring cylinder balancing system, allowing it to suspend at any angle within its operational range (typically 0°–90°). Deployment/retraction requires minimal effort (<8kgf), and its compact folded profile minimizes space occupancy—ideal for confined side-loading stations.
Key Specifications:
- Steps: Anti-slip serrated grid structure with rubber buffers at terminals (spark-prevention)
- Materials: Hot-dip galvanized carbon steel or 304 stainless steel
- Safety: Dual-sided handrails + safety locking chains
- Capacity: ≥200kg load-bearing, adaptable to most tanker heights
- Compliance: Meets hazardous material handling safety standards
As a standardized accessory for side-loading arm systems, its corrosion-resistant construction and modular design simplify installation/maintenance while significantly reducing fall risks during elevated operations.
