Road transport of hazardous liquid and gas cargo — fuel and LPG in particular — calls for high safety standards, both in vehicle engineering and operational procedure. Here are the key criteria to look for in a tanker trailer.
Tank Shell Material and Build Quality
The tank shell must be built from materials and welds suited to the chemical properties of the cargo — corrosiveness, pressure, density. Certified, pressure-tested welds are non-negotiable for long-term safety.
Compartmentalized Design
For multi-product loads, such as fuel tankers, a compartmentalized tank structure allows different fuel types to be carried separately on the same run, and helps reduce the loss of stability caused by liquid movement ("slosh") during transit.
Pressure Relief and Safety Valves
LPG tankers in particular require safety valves that maintain internal pressure balance, along with emergency relief systems. These systems must be tested and certified on a regular schedule.
Chassis and Substructure Strength
A loaded tanker has a high and dynamic center of gravity due to liquid movement. The chassis and suspension must be reinforced to handle this dynamic load, which directly affects stability during turns and braking.
Grounding and Static Electricity Protection
For flammable liquid or gas transport, grounding connections that prevent static electricity buildup during loading and unloading are a standard safety requirement.
Compliance Certificates and Periodic Inspection
Tanker trailers must be built to comply with the relevant national and international regulations (such as ADR) for the cargo carried, and must undergo regular periodic inspection.
At Foxon Trailer, we build our fuel and LPG tanker models to meet these safety requirements with the engineering and material quality they demand. For technical details, get in touch with us.
