Sinotruk Howo 8m3 Bitumen sprayer truck Angola

Name: Sinotruk Howo 8m3 Bitumen sprayer truck Angola
Brand: Sinotruk HOWO

The Sinotruk HOWO 8m3 bitumen sprayer truck is a 8000 litre asphalt distributor built on an 8x4 HOWO chassis with a 371 HP diesel engine and 10 speed manual gearbox. It is designed for road construction projects that require precise, consistent application of emulsified asphalt, fluxed asphalt, heated asphalt, and high viscosity modified asphalt. The truck operates in municipal and highway maintenance departments, contractors, and public works agencies that need to apply a uniform coating on road surfaces before paving or sealing. The intelligent spray system allows full control from the cab and adjusts spray rate automatically based on vehicle speed.

Buyer Profile

Who It Is for

Municipal public works departments managing urban road networks
National and regional highway construction contractors
Road maintenance agencies in African and Southeast Asian countries
Private contractors bidding on asphalt paving tenders
Government infrastructure projects with fixed budgets and tight delivery schedules
Road safety improvement programs requiring consistent surface sealing

Operating Problems

Problems It Solves

Inconsistent spray patterns from manual or non-adjustable distributors that waste material
Asphalt cooling too quickly during long hauls or in cold weather, leading to clogged nozzles
Manual control requiring crew to exit the cab and walk behind the truck, increasing safety risk
Lack of real-time flow adjustment causing over-spray or under-spray on variable speed routes
Noisy or unreliable pumps that fail during critical paving operations
Inadequate heating systems that cannot maintain asphalt at working viscosity for more than 2 hours

Where It Works

Application Scenarios

Municipal road maintenance crews applying seal coats to urban streets and intersections
Highway construction projects requiring continuous asphalt application on new pavement layers
Rural road upgrades in developing countries with limited access to pre-mixed asphalt delivery
Contractors working on airport taxiways and aprons where precise, even coating is critical
Paving operations in hot climates where asphalt viscosity changes rapidly with ambient temperature
Road rehabilitation projects using emulsified asphalt for surface dressing and crack sealing

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 during transit
Insulation and heat conduction oil system are installed and tested for thermal retention
Pump, piping, and nozzle array are assembled and aligned with the driveline
Computer control system is installed with modular design for easy diagnostics
Spray nozzles are calibrated and tested under full pressure before final assembly
Cab is fitted with air conditioning, bed, and tilting mechanism, then aligned with the body
Final assembly includes hydraulic system, electrical wiring, and control panel integration
Full system test is run: heating, pumping, spraying, and temperature control are verified
Truck is cleaned, painted in standard colour, and prepared for shipment

Testing

Quality Control

Every truck undergoes 100 percent testing before delivery
Tank is pressure tested and leak tested before final assembly
Heating system tested for temperature stability within two degrees per hour
Spray system tested for uniformity and flow adjustment at multiple speeds
Electrical and control systems tested under simulated field conditions
Photos and videos of the finished truck are sent to the buyer before balance payment
All components meet GB and ISO standards for road vehicles and pressure systems

Build to Order

Customization Options

Tank capacity can be adjusted to meet project-specific asphalt volume needs
Tank material can be changed to stainless steel for high purity or corrosive asphalt
Spray system can be upgraded from manual to full computer control
Cab can be fitted with additional equipment like GPS, radio, or camera systems
Tank colour and logo applied free of charge to match client branding
Manufacture to customer supplied technical drawings and specifications

Comparison

How It Compares With the Alternatives

6x4 bitumen sprayer with 5000 L tank	Lower capacity and more frequent refills but better maneuverability in urban areas
Manual spray system with fixed nozzles	No real-time flow adjustment and higher risk of over-spray or under-spray
Used truck with unknown maintenance history	No warranty, higher failure rate, and no support for spare parts or software updates

Operating Notes

Use Guide

Confirm the chassis drive configuration and hand of drive before ordering to match local road rules
Fill the tank only through the designated inlet and keep the air vent clear during filling
Preheat the asphalt to working temperature before starting the spray operation
Use the computer control system to set spray width and flow rate based on vehicle speed
Engage the automatic blowing device after each spraying session to clear residual asphalt
Drain the system and clean all nozzles and pipes after use to prevent clogging

Buyer Questions About This Truck

What is the lead time for this bitumen sprayer truck?

Generally 20 days after the advance payment is received. The exact date depends on chassis availability and equipment list.
