Truck Gangway (also referred to as Loading Gangway, Access Ladder, 3-step / 4-step / 5-step Gangway)

Truck gangway is essential safety equipment for petrochemical loading racks. It is specially designed for operators to safely board tank truck tops from the platform, connect loading arms, take samples and perform inspections.
Core Functions
Safe access: Connects loading rack and tank truck top, with fall protection, anti-slip and anti-static performance
Flexible adaptability: Accommodates various heights and vehicle types (truck / rail tankers)
Self-balancing: Holds position at any angle, steps remain horizontal at all times
Mandatory compliance: Required for top-loading operations of hazardous chemicals (GB 50160)
Main Structure
Main frame: Galvanized carbon steel / 304 stainless steel
Parallel four-bar linkage: Keeps steps horizontal
Spring cylinder balancing system: Light lifting effort, locks at any position
Anti-slip steps: Serrated grating, anti-slip coefficient ≥ 0.5
Safety railings: Hand & knee rails, safety chains / latches
Anti-collision bumpers: Prevent impact and static sparks at tanker contact
Foot-actuated lock: Step down to lock, lift to release
