Sinotruk Howo 5 ton asphalt tack truck Mozambique

Name: Sinotruk Howo 5 ton asphalt tack truck Mozambique
Brand: Sinotruk HOWO

The Sinotruk HOWO 5 ton asphalt tack truck is a 4000 litre road construction vehicle built on a 4x2 HOWO chassis with a 116 HP diesel engine and 6-speed manual gearbox. It is designed for spreading emulsified asphalt, fluxed asphalt, heated asphalt, and high viscosity modified asphalt on road surfaces during paving and patching operations. The truck delivers precise, adjustable spray patterns from 2 to 6 metres wide and maintains consistent application rates across varying speeds. It is used by road contractors, municipal works departments, and infrastructure developers in regions with limited access to centralized asphalt supply or where flexible, on-site application is required.

Internal piping and nozzles made of stainless steel for corrosion resistance
Cab and body panels constructed from steel with anti-corrosion coating
Heat transfer oil system with insulated pipes to maintain thermal efficiency
Control panel and electrical wiring rated for industrial use in dusty and wet environments

How It Is Built

Manufacturing Process

Chassis is received from Sinotruk and wheelbase is verified against the tank layout drawing
Tank shell is cut, rolled, and welded with internal baffles to reduce surge
Tank is pressure tested and heat sealed before internal components are installed
Heat conduction oil system and burner are installed and tested for safe operation
Hydraulic pump, asphalt pump, and motor are mounted and aligned to the driveline
Spray nozzles, piping, and control valves are installed with individual electronic control units
Control system is programmed and tested for accuracy and response time
Cab and body are painted in fire service red or customer specified colour with logo applied free of charge
Full system test is conducted on the factory apron: heating, spraying, and control response
Photos and videos of the finished truck are sent to the buyer before balance payment

Comparison

How It Compares With the Alternatives

4x2 truck with 2000 L tank	Carries half the asphalt but is more maneuverable in tight urban sites
Manual spray system with fixed nozzles	Less precise and harder to adjust on the move, higher material waste
Used asphalt distributor from Europe	Higher initial cost and longer delivery time, parts and service may be delayed by months

Operating Notes

Use Guide

Confirm left or right hand drive at order stage to match local traffic rules
Fill the asphalt tank only through the designated inlet and avoid overfilling
Start the burner at least 30 minutes before spraying to ensure even heating
Set the spray rate and width in the cab based on vehicle speed and road width
Use the automatic blowing device after each use to clear nozzles and pipes
Drain the tank and flush the system with solvent if the truck will not be used for more than 24 hours
