The Whole Vehicle Has A Large Loading Area With A Loading Capacity Of About 140 Cubic Meters, Realizing Large-Volume Transportation, Nearly Twice That Of A 13-Meter Model. The Single-Trip Capacity Is Significantly Improved, Effectively Reducing Unit Transportation Cost And Improving Operating Revenue, Making It A Strong Choice For Efficient Logistics Transportation. The Frame Is Made Of High-Quality High-Strength Steel Plates, With Thickened Main Beams Welded With Multiple Cross Beams, Featuring High Strength And Strong Torsion And Load Resistance. The Checkered Floor Is Anti-Slip And Wear-Resistant, And With Devices Such As Tie-Down Winches, Cargo Is Fastened More Securely. It Is Equipped With High-Quality Axles, Suspension System And Braking Device, Ensuring Safe And Stable Driving Under Full Load. With Excellent Workmanship And Fine Paint, It Is Widely Applicable To Long-Distance Transportation Of All Kinds Of Oversized Cargo Such As Machinery And Equipment, Engineering Building Materials, Steel Pipes And Plates, And Bulk Cargo, And Is Deeply Trusted And Praised By Customers, With High Cost Performance And Outstanding Quality.

Precautions

1. When Loading Cargo, The Load On The High Board And The Low Board Should Be Reasonably Distributed. Heavy Cargo Should Be Placed On The Low Board As Much As Possible To Keep The Front And Rear Axle Loads Even And Avoid Eccentric Loading And Overloading, So As To Ensure Driving Safety.

2. The Total Mass Of The Whole Vehicle Shall Not Exceed The Limit Set By National Regulations (The Total Mass Of A Six-Axle Vehicle Shall Not Exceed 49 Tons). Overloading Is Strictly Prohibited To Avoid Damaging The Frame, Suspension And Other Structures.

3.  Before Loading Over-Height Cargo, The Total Height Of The Cargo And The Vehicle Must Be Calculated. Generally, The Cargo Height On The Low Board Shall Not Exceed 2.8 Meters And That On The High Board Shall Not Exceed 2.4 Meters, So As To Ensure Compliance With Road Height Limit Requirements And Pass Through Height-Limited Sections Safely.

4. Cargo Must Be Firmly Tied And Fixed With Tools Such As Tie-Down Winches And Steel Wire Ropes To Prevent Cargo From Shifting During Transportation And Causing Safety Hazards.

5.  During Driving, Maintain A Reasonable Speed And Avoid Sudden Braking And Sharp Turns To Prevent Cargo From Shaking And Sliding Sideways.

6. Regularly Inspect Key Parts Such As Frame Welds, Axles, Tire Pressure, Braking System And Lights. If Any Abnormality Is Found, Repair And Maintain In Time. Driving With Defects Is Strictly Prohibited, So As To Extend The Service Life Of The Vehicle And Ensure Long-Term, Efficient And Safe Operation With Guaranteed Driving Safety.
