Sinotruk Howo 12m3 bitumen lorry Tajikistan

Name: Sinotruk Howo 12m3 bitumen lorry Tajikistan
Brand: Sinotruk HOWO

The Sinotruk HOWO 12m3 bitumen lorry is a 12000 litre asphalt distributor built on an 8x4 HOWO chassis with a 220 HP diesel engine and 8 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 at speeds between 1.5 and 7 km/h and can adjust spray width from 2 to 6 metres. It is used by national and municipal road agencies, contractors, and maintenance fleets in regions with high road development activity, including Central Asia and Africa.

Buyer Profile

Who It Is for

National and municipal road authorities managing large-scale paving programs
Contractors bidding on public road construction tenders with strict quality and delivery requirements
Road maintenance units operating in remote or underdeveloped regions
Aggregates and paving supply companies supplying asphalt to on-site contractors
Government procurement agencies equipping new road construction fleets

Operating Problems

Problems It Solves

Inconsistent spray patterns caused by manual or uncalibrated distributors leading to material waste
Asphalt cooling during transport due to inadequate heating systems or poor insulation
Long refilling cycles when tank capacity is too small for continuous paving
Lack of remote control or real-time feedback in spray systems causing over-application or missed spots
Poor performance on unpaved or rough terrain due to weak chassis or low ground clearance
High maintenance costs from non-modular or poorly designed control systems

Where It Works

Application Scenarios

National road construction projects requiring high-volume, consistent asphalt application
Maintenance of rural and regional roads with limited access to central batching plants
Paving operations in mountainous or remote areas where asphalt must be transported long distances
Contractor fleets working under tight schedules with multiple daily shifts and no downtime
Road rehabilitation projects where precise control over spray rate prevents over-application
Projects in high-temperature climates where asphalt viscosity must be maintained during transport

Build Materials

Materials

Carbon steel tank with internal reinforcement and heat insulation layer
Aluminium alloy panels on the cab and side panels for corrosion resistance
Stainless steel nozzles and pump components for high wear resistance
Rexroth hydraulic pump and ISB180 40 motor for reliable power transmission
Heat conduction oil system with insulated piping and temperature sensors

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 transport
Tank is pressure tested and inspected for leaks before internal coating is applied
Bitumen pump, hydraulic system, and heating system are installed and aligned with the driveline
48 nozzles are mounted and calibrated with individual electronic control units
Control system is programmed with software for speed-based spray rate adjustment
Cab and rear platform control panels are installed and tested for dual operation
Whole vehicle is painted in standard red or customer specified colour with logo applied free of charge
Final test includes full system operation, spray pattern verification, and temperature control check

Testing

Quality Control

All trucks are 100 percent tested before delivery
Tank and pressure systems undergo leak and pressure testing to GB39.5 standards
Heating system tested for temperature stability within two degrees per hour
Spray system tested at full range of speeds and widths with nozzles individually verified
Photos and videos of the finished truck sent to buyer before balance payment
In-house testing includes non-destructive testing for weld integrity and material strength

Build to Order

Customization Options

Tank capacity can be adjusted between 8000 and 12000 L based on project needs
Tank material can be changed to stainless steel upon request for specific asphalt types
Left or right hand drive chassis available to match local traffic rules
Tank colour and logo applied free of charge to match client branding
Spray system can be upgraded from manual to full computer control

Comparison

How It Compares With the Alternatives

6x4 asphalt distributor with 8000 L tank	Lower capacity requires more refills but is more maneuverable in tight urban sites
Manual spray system with no computer control	Slower to adjust and less precise but simpler to maintain and repair
Asphalt truck with basic heating but no temperature control	Higher risk of asphalt cooling or over-heating during long hauls

Operating Notes

Use Guide

Confirm chassis drive configuration and wheelbase at order stage to match local road access and registration rules
Fill asphalt only through the designated inlet and avoid overfilling to prevent pressure build-up
Set heating system to maintain asphalt temperature within two degrees per hour during transport
Use computer control system to match spray rate to vehicle speed for consistent coverage
Clean nozzles and piping after each use with solvent or rinse fluid to prevent clogging
Free operator training is available at the factory before shipment

Buyer Questions About This Truck

What is the lead time for this bitumen lorry?

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

Can the tank be stainless steel instead of carbon steel?

Yes. The standard tank is carbon steel. Stainless steel is available upon request. Specify the asphalt type and storage duration for material confirmation.

What are your payment terms?

T/T with 30 percent deposit and 70 percent before delivery. We send photos and videos of the finished truck before you pay the balance.

Do you supply right hand drive?

Yes. The chassis is ordered in left or right hand drive to match your traffic regulations. Confirm this at order stage as it cannot be changed later.

How is the truck shipped?

By Ro-ro or bulk ship from a China main port. Trade terms can be EXW, FOB, CFR, or CIF.

What warranty and after sales support do you provide?

The whole vehicle is guaranteed for one year and core parts on some products for two years. Our overseas engineers make regular return visits and provide technical training and manuals before delivery.
