Basic Product Introduction

Prime Mover Industries heated asphalt bitumen tank semi-trailer is a professional special liquid transport vehicle tailor-made for hot bitumen, liquid asphalt, coal tar and pitch transportation. Different from ordinary oil tank trailers, this model is equipped with a **complete thermal insulation layer + independent circulating diesel heating system**, which can keep liquid asphalt in constant low-viscosity flowing state during long-distance highway, mountain and high-temperature cross-border transport, effectively solving the solidification, pipeline blockage and unloading difficulties of bitumen in long-time transit.

The tank body adopts thickened Q345B high tensile carbon steel one-time rolling and full automatic submerged arc welding, equipped with anti-wave partitions inside to reduce liquid sloshing and improve driving stability. The reinforced low gravity chassis with multi-axle balanced load design meets highway axle load standards in Africa, Middle East, Southeast Asia and Latin America. It supports integrated functions of self-loading, pressure pumping unloading and circulation heating, becoming standard core equipment for road construction fleets, asphalt mixing plants and liquid chemical logistics companies.

Core Product Advantages

Efficient Constant Temperature Heating System, No Bitumen Solidification

Adopts imported high-power diesel burner matching bottom circulating heating coil, uniform heat conduction without local overheating. It only takes 5–8 minutes to melt solidified bitumen at low temperature; digital temperature control automatically maintains 140–160°C optimal flow viscosity, avoiding pipeline blockage caused by asphalt cooling during long-distance transportation. Independent fuel tank for heating system, separated from tractor fuel supply, no restriction on driving heating operation.

Ultra-Thick Full Thermal Insulation Layer, Low Energy Consumption

80mm high-density rock wool full-surround insulation layer plus stainless steel outer protective cover, effectively reduce heat loss by over 70%. Under 25°C ambient temperature, the temperature drop per 8 hours of transportation is less than 10°C, greatly cutting extra heating fuel costs for long-haul fleets, especially suitable for trans-desert and cross-mountain long-distance transport.

Anti-Leak & Anti-Sloshing Tank Safety Design

Full automatic submerged arc welding tank body, passed 0.8MPa high-pressure air tightness leak test before delivery; built-in multi-group anti-wave partitions weaken liquid asphalt sloshing during acceleration, braking and sharp turns, lowering rollover risk. Equipped with top pressure relief valve, rear emergency pneumatic cut-off valve and fire isolation baffle, fully meet hazardous liquid transport safety standards worldwide.

Reinforced Low Gravity Chassis, Stable Heavy Load Driving

Deepened I-beam integral chassis, lower center of gravity than ordinary tank trailers, stronger anti-roll performance on bumpy construction roads. Four-axle optional load distribution design reduces single-axle pressure, avoiding overweight fines at border inspection stations. All pipeline joints adopt high-temperature resistant sealing gaskets, adapt to long-term high-temperature liquid transport without aging leakage.

Multi-Scenario Flexible Operation & Low Maintenance Cost

Support three unloading modes: gravity self-flow unloading, hydraulic pump pressure unloading and circulating heating cleaning. Top manhole facilitates internal tank inspection and residue cleaning. Standardized global universal spare parts for burners, axles and brake systems, easy to purchase local accessories overseas and shorten maintenance downtime.

Main Application Fields

Highway & Municipal Road Construction

Core transport equipment for asphalt mixing plants, delivering hot liquid asphalt to road paving sites, suitable for expressway, urban road, airport runway and bridge pavement engineering projects. Constant temperature heating ensures asphalt construction quality without solidification waste.

Asphalt Plant Raw Material Logistics

Long-distance transportation of crude bitumen from refineries to regional mixing stations; multi-volume optional tank body realizes large-batch centralized delivery and improves plant raw material storage turnover efficiency.

Cross-Border Heavy Liquid Chemical Transport

Compliant with international hazardous liquid transport regulations, widely used for cross-border bitumen, coal tar and pitch transportation in Africa, Middle East and Southeast Asia. Complete certification documents support smooth customs clearance without detention.

Mining & Waterproof Material Industry

Transport modified asphalt, waterproof pitch and high-temperature industrial raw materials for mining infrastructure, tunnel waterproof and building material factories; stainless steel tank upgrade option avoids chemical corrosion to tank wall.

Complete Installation & Commissioning Operation Flow

Step 1: Pre-Delivery Matching Inspection

After the trailer arrives at the customer yard, park the tractor and tank trailer on flat hard ground, lock tractor hand brake and place anti-slip triangular blocks; check heating system diesel oil volume, hydraulic pump oil level and all pipeline tightness to confirm no air or liquid leakage.

Step 2: Tractor Fifth Wheel Docking

Reverse the tractor to align with trailer kingpin, lower landing gear to adjust height, complete fifth wheel locking, pull the safety pin to confirm full engagement, connect air brake pipeline, electrical lighting circuit and heating system control wiring harness.

Step 3: Heating System Test Run

Turn on the burner control switch, preheat the circulating coil for 5 minutes, observe real-time temperature display, check whether the heating pipeline circulates evenly without local overheating; test emergency cut-off valve function to ensure automatic shut-off under abnormal pressure.

Step 4: Asphalt Loading Operation

Open the top manhole or side loading port, connect refinery discharge pipeline for sealed filling; real-time monitor liquid level to avoid overfilling exceeding rated volume, close all valves tightly after loading and lock manhole safety buckle.

Step 5: Unloading & Post-Use Cleaning

Drive to construction site, start heating system to keep bitumen fluid state, open rear unloading valve for gravity outflow or start hydraulic pump pressure discharge; after emptying the tank, inject hot diesel oil circulation to clean residual asphalt inside tank and pipelines to prevent long-term solid residue blockage.

Standard Daily & Periodic Maintenance Specifications

Daily Pre-Trip Mandatory Inspection

• Heating system: Check burner fuel pipeline for oil leakage, clean burner nozzle carbon deposit, verify temperature controller normal display, inspect heating coil insulation for damage.
• Tank body & pipeline: Check tank welding seams, unloading valves and all high-temperature sealing gaskets for bitumen leakage; clean residual asphalt at pipeline joints.
• Chassis & running gear: Calibrate uniform tire pressure of all axles, inspect suspension U-bolt tightness, test ABS brake response and air tank drainage.
• Safety accessories: Check pressure relief valve, fire barrier and emergency cut-off valve for flexible opening and closing; inspect rear warning signs and reflective strips integrity.

Scheduled Cycle Maintenance

• Every 5,000 km: Lubricate axle bearings, kingpins and landing gear transmission gears; tighten all chassis and tank fixing brackets; replace heating system filter element.
• Every 20,000 km: Comprehensive replacement of high-temperature resistant sealing gaskets for all pipelines; disassemble and clean burner combustion chamber and circulating heating coil; calibrate multi-axle braking balance.
• Every 50,000 km: Conduct full tank air tightness pressure test; perform overall chassis anti-rust touch-up painting; overhaul hydraulic unloading pump and heating control circuit; detect internal anti-wave baffle welding firmness.

Forbidden Operation Rules to Extend Service Life

• Do not heat the tank body without liquid bitumen inside, to avoid empty burning damage to heating coil and tank wall.
• Strictly prohibit overloading beyond rated tank volume, to prevent liquid overflow during driving and safety accidents.
• Avoid emergency braking and sharp turning under full load, to reduce liquid sloshing impact on tank structure.
• Do not store solidified asphalt in the tank for more than 72 hours continuously; timely circulation heating cleaning is required after unloading.
• Prevent direct impact on tank insulation protective shell during loading and unloading to avoid heat preservation performance attenuation.
