Overview

The Tremcar Fuel Tank Trailer is an aluminum petroleum tanker designed for transporting gasoline, diesel fuel, aviation fuel, ethanol blends, and other compatible refined petroleum products. Tremcar offers petroleum trailers for both United States and Canadian operations, including tandem-axle, tri-axle, four-axle, and B-train configurations.

United States models are commonly manufactured to the DOT 406 cargo tank specification, while Canadian versions may use the corresponding TC 406 specification. Both are designed specifically for low-pressure flammable-liquid transportation.

Multi-compartment construction allows distributors to transport several fuel grades within one trailer. A single load may include regular gasoline, premium gasoline, diesel fuel, or other compatible products assigned to separate compartments.

Bottom-loading equipment, vapor recovery, overfill protection, emergency valves, brake interlocks, and API discharge adapters support safe and efficient loading and delivery operations.

Key Characteristics

The Tremcar Fuel Tank Trailer commonly uses an elliptical aluminum tank designed to provide a low center of gravity and reduced empty weight. Aluminum construction helps increase available payload while providing corrosion resistance for compatible petroleum products.

Multiple sealed compartments allow different fuel grades to remain separated during transportation. Compartment sizes can be configured around a fleet’s typical delivery requirements.

Bottom-loading connections are commonly grouped inside a protected cabinet. This arrangement allows terminals to load fuel without requiring the operator to work from the top of the tanker.

Vapor-recovery equipment captures displaced fuel vapors during loading and unloading. Overfill sensors, pneumatic internal valves, and brake-interlock systems provide additional protection against spills and accidental movement.

Tremcar also offers larger multi-axle and B-train petroleum configurations for Canadian operations where regional weight and length regulations allow additional capacity.

Common Specifications

Cargo Tank Specification

Tremcar petroleum trailers are commonly manufactured to:

DOT 406 requirements for United States operation

TC 406 requirements for Canadian operation

The certification plate identifies the exact cargo tank specification, design limits, test requirements, and manufacturing information.

Construction Material

The tank shell is commonly manufactured from aluminum alloy.

Certain current TC 406 models use 5454-H32 aluminum alloy for the shell and 5454-HO aluminum alloy for the domed and flanged tank heads.

Tank Shape

An elliptical tank shape is common. The low-profile oval design helps lower the trailer’s center of gravity compared with a tall cylindrical tank.

Capacity

Common United States configurations include approximately:

  • 8,500 gallons
  • 9,000 gallons
  • 9,500 gallons

Capacity depends on compartment arrangement, axle configuration, product density, trailer weight, and legal operating limits.

Larger Canadian configurations may provide approximately 42,000 to 57,000 liters.

B-train configurations can provide additional combined capacity where legally permitted.

Compartments

Fuel trailers may be configured with:

  • Single compartment
  • Three compartments
  • Four compartments
  • Five compartments
  • Six compartments
  • Custom compartment arrangements
  • Multi-compartment trailers allow several fuel grades or products to be transported in one trip.

Bulkheads and Baffles

Compartments are separated by bulkheads. Double-bulkhead construction may be specified between selected compartments to provide additional product separation.

Baffles may be used to control liquid movement within certain tanks or compartments.

Bottom Loading

Bottom-loading adapters are commonly installed in a protected cabinet along the side of the trailer.

Bottom loading reduces the need for operators to climb onto the tanker and allows rapid connection at compatible loading terminals.

Discharge System

Available discharge equipment may include:

  • Three-inch gravity discharge
  • Four-inch API adapters
  • Pump-off piping
  • Driver-side discharge

  • Emergency shear sections

Vapor Recovery

Vapor-recovery connections allow displaced vapors to return to the terminal or storage system during loading and unloading.

The system can include vapor vents, rails, piping, adapters, and interlocks.

Overfill Protection

Electronic overfill sensors monitor the liquid level in each compartment during loading. Common systems use an optic socket that connects the trailer to the loading rack.

If the system detects an unsafe condition, the terminal can stop product flow.

Emergency Valves

Pneumatically operated internal emergency valves are commonly installed at compartment outlets. These valves are designed to stop product flow during an emergency or separation of external piping.

Brake Interlocks

Brake interlocks may be connected to the loading adapters, vapor-recovery connection, or cabinet equipment.

The interlock applies or maintains the trailer brakes while loading equipment is connected, helping prevent accidental drive-away incidents.

Driver and Operator Considerations

Drivers must understand the handling effects created by liquid movement. Fuel can shift during acceleration, braking, lane changes, and cornering, increasing the possibility of rollover or loss of control.

Speed should be reduced before curves, ramps, intersections, and uneven road surfaces. Drivers should brake early and maintain additional following distance.

Before loading, the operator must verify the product, compartment assignment, available compartment capacity, terminal connection, vapor-recovery system, and overfill monitor.

Each compartment must contain the correct product quantity and required outage space. Filling a compartment beyond its approved level can create an unsafe condition as the product expands.

Before departure, the driver should confirm that loading adapters, vapor connections, internal valves, cabinet doors, hoses, and caps are properly disconnected and secured.

Maintenance and Ownership Notes

Routine maintenance should include the tank shell, heads, bulkheads, compartment piping, internal valves, discharge adapters, vapor-recovery equipment, manways, vents, and overfill-monitoring system.

The aluminum tank should be inspected for cracks, corrosion, abrasion, dents, weld damage, and signs of impact.

Cabinet components should be kept clean and properly labeled. Product adapters, seals, dust caps, and gaskets should be replaced when worn or damaged.

Emergency valves and remote shutdown equipment should be tested according to applicable procedures.

Suspension components, brakes, ABS equipment, tires, wheels, wheel ends, lighting, and the trailer’s electrical system require regular preventive maintenance.

Repairs affecting the cargo tank structure must be performed by a properly qualified and registered cargo tank facility.

Regulatory and Compliance Notes

The Tremcar Fuel Tank Trailer is designed for repeated terminal-to-customer petroleum delivery cycles. Multi-compartment layouts allow a driver to deliver several fuel grades during one route.

Compartment planning is critical. The dispatcher and driver must match each product quantity to an appropriately sized compartment while maintaining legal axle weights and adequate outage.

An incorrect product connection can contaminate an entire storage tank or vehicle compartment. Drivers must verify product codes, compartment assignments, hose connections, and delivery locations before transferring fuel.

Even with compartment bulkheads, liquid movement affects braking and cornering. Partially loaded compartments can create more noticeable surge than full compartments.

Real World Operating Notes

Tremcar fuel tank trailers are subject to extensive regulations governing cargo tank construction, hazardous materials, vehicle operation, loading, unloading, testing, maintenance, and emergency response.

United States operations may fall under requirements administered by the Federal Motor Carrier Safety Administration and Pipeline and Hazardous Materials Safety Administration.

Canadian operations must comply with Transport Canada requirements and applicable provincial regulations.

Drivers commonly require a commercial driver’s license with tanker and hazardous materials endorsements or the applicable Canadian equivalents.

Petroleum loads require correct shipping papers, placards, emergency response information, product identification, and security procedures.

Cargo tank inspections and tests must remain current. Required examinations may include external visual inspections, internal visual inspections, leakage tests, pressure tests, thickness testing, and inspection of emergency equipment.

Vapor-recovery, overfill-protection, emergency-valve, and brake-interlock systems must remain operational and compatible with the facilities where the trailer is loaded and unloaded.
