A used HOWO prime mover for construction equipment transport from China typically costs FOB USD 13,000–27,000 per unit. For excavators, loaders, bulldozers, and road machinery, a 6×4 truck with 371–430HP is the correct starting point. The final choice must match loaded trailer weight, route conditions, fifth-wheel compatibility, and verified refurbishment quality.
An export-prepared used HOWO prime mover normally falls within FOB USD 13,000–27,000. Standard 371HP or 375HP 6×4 units usually sit in the lower or middle range. Trucks with 400–430HP, new tires, major drivetrain work, or heavy-duty axles move toward the upper end.
A complete quotation must identify the chassis, engine output, transmission, rear axles, steering position, tire condition, fifth wheel, refurbishment scope, loading port, and validity period. Buyers comparing used HOWO tractor heads for lowbed transport should reject offers that provide only a year, color, and horsepower without vehicle-specific inspection evidence.
Mechanical condition, drive configuration, transmission, rear axles, tires, cab condition, fifth wheel, and refurbishment depth create the largest price differences. Model year identifies a truck, but it does not prove engine, clutch, or rear-axle condition.
A 6×4 normally costs more than a 4×2 because it has two driven rear axles and greater traction capacity. New 12R22.5 tires, a replacement cab, an overhauled gearbox, HC16 hub-reduction axles, or a heavy-duty fifth wheel also raise the quotation.
A 6×4 HOWO prime mover is the correct choice for most construction equipment transport. Two driven rear axles provide stronger traction, better load distribution, and more reliable low-speed control when pulling a lowbed trailer on gradients, unpaved access roads, quarry routes, or construction sites.
| Configuration | Best Application | Main Advantage | Main Limitation |
|---|---|---|---|
| 4×2 | Light highway trailers and lower combination weights | Lower fuel and tire cost | Less traction and rear-axle margin |
| 6×4 | Excavators, loaders, bulldozers, graders, and lowbed work | Better traction and heavy-haul stability | Higher fuel use and tire cost |
A 4×2 becomes a false economy when it loses traction, overloads one driven axle, or needs recovery support. For mixed highway and site work, the operating margin of a 6×4 matters more than modest fuel and tire savings.
A 371–400HP HOWO is suitable for many medium equipment movements, while 420–430HP is better for heavier combinations, long gradients, rough routes, and repeated low-speed starts. These horsepower ranges are configuration references, not fixed towing limits.
Check the final choice against gross combination weight, axle ratio, transmission condition, brakes, cooling performance, and route gradient. A 30-ton excavator does not create only a 30-ton towing requirement; the lowbed, ramps, tools, and fuel must also be included. Higher horsepower cannot correct weak brakes, unsuitable gearing, or an overloaded trailer.
The tractor, trailer, and machine must be selected as one transport system. Confirm equipment operating weight, trailer tare weight, permitted payload, axle ratings, tire capacity, fifth-wheel height, kingpin size, deck height, ramp angle, and the legal gross combination limit in the destination market.
Medium excavators often use a three-axle lowbed, while heavier machines may require four axles or a reinforced frame. The guide on matching a lowbed trailer to construction machinery explains how deck length, axle count, ramp angle, and concentrated load affect the specification.
As a recognized securement reference, the FMCSA cargo-securement rules apply dedicated requirements to heavy machinery weighing 4,536 kg or more. Destination-country rules must still be checked separately. The machine must be restrained against forward, rearward, lateral, and vertical movement; tractor power never replaces correct trailer capacity and securement.
The value of a used HOWO tractor head depends more on verified drivetrain condition than on exterior appearance. Mechanical refurbishment increases the price because it addresses the systems that determine whether the truck can pull a loaded trailer reliably.
Inspection should cover the engine, cooling, clutch, gearbox, propeller shafts, rear axles, brakes, steering, fifth wheel, tires, electrical systems, and cab controls. Fresh paint does not prove clutch, brake, axle, or cooling condition.
A credible refurbishment record shows the truck before work begins, identifies components repaired or replaced, and provides final operating videos tied to the same chassis number.
Final payment should follow a vehicle-specific inspection and work-readiness test. The acceptance package must connect the chassis and engine numbers to the sales contract, refurbishment records, test videos, and shipping documents.
Stable engine start without serious oil, fuel, coolant, or air leakage
Normal dashboard warnings and air-pressure build-up
Smooth clutch engagement without slipping or severe vibration
Forward, reverse, and low-gear movement tests
Consistent steering and service-brake response
Rear axle, differential, and propeller-shaft noise checks
Fifth-wheel plate, jaws, locking handle, mountings, and lubrication
Tire size, tread, sidewalls, rims, and wheel fasteners
Trailer air and electrical connections when available
The guide to pre-shipment checks for a HOWO tractor truck provides a fuller sequence.
Based on Qingdao Alston Motors’ inspection and export experience, a prime mover is ready for equipment transport only when the drivetrain, brakes, rear axles, fifth wheel, tires, and trailer connections pass checks linked to the actual order.
Total landed cost includes the truck price, port movement, export handling, ocean freight, insurance, destination charges, duties, taxes, registration, and inland delivery. A low FOB figure is not automatically the lowest delivered price.
Complete tractor units are commonly shipped by Ro-Ro or bulk vessel. Flat-rack shipment may suit certain schedules or destinations. The quotation should state whether port delivery, battery preparation, lashing, and shipping documents are included.
Import eligibility, steering rules, emissions limits, vehicle-age restrictions, and registration requirements must be confirmed before final payment.
A lower-priced prime mover costs more overall when weak refurbishment, incorrect gearing, worn tires, clutch problems, axle repairs, or trailer mismatch reduce operating availability. A USD 2,000 saving can disappear after a clutch replacement, ten tires, fifth-wheel repairs, or several weeks of project delay.
Compare offers by gross combination weight, route gradient, fuel use, tire requirement, first-year maintenance, parts availability, and downtime exposure. For Qingdao Alston Motors, the practical buying rule is to select the configuration with the lowest verified operating risk, not simply the lowest FOB price.
Review the supplier’s refurbishment and export experience, then request a project-specific prime mover quotation with the equipment weight, lowbed type, route, steering position, destination country, and discharge port.
An export-prepared unit normally costs FOB USD 13,000–27,000, depending on horsepower, drivetrain condition, tires, cab work, rear axles, fifth wheel, and refurbishment depth.
Yes, for many medium excavators on suitable routes. Trailer tare weight, total combination weight, gradients, axle ratio, brakes, cooling, and clutch condition must also be checked.
Yes. A 6×4 provides better traction and rear-axle load distribution for heavy equipment, rough access roads, gradients, and construction-site operation.
Heavy-haul combinations often use a 90 mm kingpin interface, but the fifth wheel and trailer kingpin must be measured and confirmed before shipment.
No. The prime mover and lowbed are normally quoted separately unless the contract clearly lists a truck-and-trailer package.
Test the engine, clutch, gearbox, brakes, steering, rear axles, fifth wheel, tires, air system, electrical connections, and identification documents.
No. FOB normally excludes ocean freight, destination handling, customs duties, taxes, registration, and inland delivery.
