<\/span><\/h2>\nMaintenance is not something to figure out after the truck arrives. The daily and periodic checks below are standard for heavy-duty trucks and specialized vehicles, and the intervals should always follow the actual vehicle, engine, and component manufacturer manuals \u2014 not a generic schedule.<\/p>\n
Ki\u1ec3m tra h\u00e0ng ng\u00e0y:<\/strong> tire condition and pressure, fluid leaks, hydraulic hoses, lights, air system pressure, warning indicators, and for specialized bodies, the specific mechanism (tipping cylinder, compactor cycle, crane pins, pump operation).<\/p>\nKi\u1ec3m tra \u0111\u1ecbnh k\u1ef3:<\/strong> engine oil and filters, transmission and differential fluids, brake system and wear, suspension components, wheel bearings, hydraulic oil and filter, PTO operation, and body-specific wear points such as dump body hinges, compactor wear plates, or crane structural welds.<\/p>\nThe most common mistake here is treating maintenance as a cost to minimize rather than an uptime investment. On a truck running 250 days a year, one extra day of downtime costs more than a year’s worth of scheduled maintenance parts. Buyers should plan the parts supply chain before delivery, not after the first failure.<\/p>\n

Then verify the result against the destination country’s legal gross weight and axle-load limits. All three checks have to pass. Payload is not a single number \u2014 it’s the lowest of the technical, structural, and legal limits.<\/p>\n
<\/span>Which axle configuration should I choose?<\/span><\/h3>\nIt depends on the route and payload. 4\u00d72 suits light urban work and paved-road tankers. 6\u00d74 is the general-purpose choice for construction haulage and tractor units. 6\u00d76 and 8\u00d78 are for severe off-road conditions. 8\u00d74 gives higher payload capacity but adds tare weight, tire cost, and turning radius. The right answer comes from the duty cycle, not the catalog.<\/p>\n

Paved highway work favors taller gearing and lighter bodies for fuel economy. Gradient on the loaded leg is the single biggest factor in powertrain selection.<\/p>\n

Any fuel figure quoted without these conditions attached is not useful for comparison. Ask what duty cycle the number was measured under.<\/p>\n

Downtime is the most commonly overlooked line and often the largest. Purchase price is typically only a fraction of the lifetime cost.<\/p>\n

For crane trucks, add maximum lifting weight, working radius, and lifting height. For tankers, add product type and compartment requirements. For fire apparatus, add water and foam capacity and pump requirements.<\/p>\n

Confirm emission standard, homologation or type approval, registration eligibility, axle-weight limits, vehicle dimensions, steering side, lighting, braking, and safety requirements. Regulatory details change, so verify against the current official source rather than relying on a supplier’s general statement.<\/p>\n

The right choice depends on vehicle dimensions, weight, whether it can be driven onto the vessel, quantity, route, and destination port. Commercial terms (FOB, CFR, CIF) determine who pays freight and insurance, and quotes should always be compared on the same basis.<\/p>\n
