Product Features
1. Exceptionally High Unloading Efficiency
Utilizing a hydraulic rear-tipping lift mechanism, the trailer features one-touch automatic unloading-requiring neither manual labor nor a forklift. The discharge of bulk cargo is completed within minutes, making it several times more efficient than standard side-board trailers.
2. Robust Load-Bearing Capacity & Stable Center of Gravity
The 3-axle design ensures uniform axle load distribution, providing superior stability during heavy hauling and lifting operations to minimize the risk of rollovers. The frame's longitudinal beams are thickened to offer strong resistance against torsion and impact, making the trailer ideally suited for heavy-duty operating conditions.
3. Simple Structure, Rugged & Durable
Comprising primarily a frame, cargo box, hydraulic cylinders, and a lifting mechanism, the trailer dispenses with complex side-boards or cage-style fencing. This simple design results in a low failure rate and facilitates easy maintenance.
4. Clean Discharge, Non-Stick Cargo Box
The cargo box floor typically features a curved or sloped design; this prevents materials such as sand, gravel, coal, and excavated soil from adhering to the surface, ensuring a more thorough and complete discharge.
5. High Regulatory Compliance
Designed strictly in accordance with national dimensional standards-and equipped with features such as ABS, disc brakes, and air suspension-the trailer fully meets the various weight-limit enforcement regulations and roadworthiness requirements across multiple regions.
Frequently Asked Questions
Slow Lifting / Insufficient Lifting Power
Possible Causes: Low hydraulic fluid level, clogged filter element, worn hydraulic pump, relief valve pressure set too low.
Solution: Replenish hydraulic fluid → Replace filter element → Inspect hydraulic pump → Adjust relief valve pressure.
Automatic Descent After Lifting
Possible Causes: Internal leakage within the hydraulic cylinder, poor sealing of the check valve, oil leakage in the hydraulic lines.
Solution: Inspect and replace cylinder oil seals → Repair or replace the check valve → Tighten fittings; replace hydraulic hoses.
Prone to Tipping Over During Unloading
Possible Causes: Uneven ground, off-center or unbalanced load, lifting too rapidly, excessive vehicle speed.
Solution: Unload only on level, firm ground; ensure the load is centered and distributed evenly; operate the lifting mechanism slowly; engage neutral gear and apply the parking brake while unloading.
Can a rear-tipping dump truck be converted to a front-tipping or side-tipping configuration?
Unauthorized modification is not recommended.
The structural design, center of gravity, and hydraulic cylinder placement differ completely; such modifications make the vehicle highly prone to tipping over or suffering frame fractures, and also render it non-compliant with regulations.
