Product Overview
The Rear Hydraulic Dump Semi-Trailer is a heavy-duty bulk transport solution engineered for mining, construction, and agricultural material logistics. Featuring a high-strength chassis, a U-shaped wear-resistant cargo box, and a genuine HYVA front-lifting system, it guarantees stability during high-angle tipping and reduces maintenance downtime for international fleet operations.
Engineering Features & Structure
U-Shaped Cargo Box Design: Optimized geometry minimizes material sticking and speeds up discharge while improving structural resistance against abrasive rock impacts.
Balanced Load Distribution: Equipped with 2-axle/3-axle mechanical equalizer suspensions and mass balance blocks between leaf springs to maintain equal deflection across all axles.
Leak-Proof Hydraulic Line Assembly: Sealed fluid channels and dustproof couplings reduce seal degradation and hydraulic oil contamination risk.

Corrosion Control & Finishing
Shot Blasting & Cleaning: Complete frame surface blasted to Sa 2.5 standard to strip welding slag and rust.
Electrophoretic & Polyurethane Coating: Electrophoretically treated undercoat with an anti-corrosion primer and color-customizable polyurethane topcoat, delivering surface protection for over 10 years.
Step-by-Step Customization Process
Requirements Alignment: Define payload targets, cargo density, road conditions, and local highway compliance limits with our engineering team.
Technical Blueprinting: Issue 2D/3D structural drawings detailing main beam dimensions (500mm depth), axle spacing, and cylinder positioning for buyer approval.
Component Selection: Confirm brand choices for axles, tires, landing gear (JOST/Taihua), and hydraulic cylinder models.
Production & Inspection: Manufacture chassis and cargo box under strict quality checks, followed by full hydraulic load testing.
Final Finishing & Delivery: Complete shot-blasting, electrophoretic priming, polyurethane painting, and export shipping preparation.
Global Logistics & Accessories
- Included Tooling: Chassis-mounted lockable steel toolbox, towing accessories, heavy-duty bottle jack, lug wrench, and spare 24V LED lamps.
- Marine Protection: Sa 2.5 shot-blasting, electrophoretic base coat, full-body anti-rust wax spray, and waterproof wrapping for cylinders and 451 air tanks.
- Shipping Modes: Ro-Ro (Roll-on/Roll-off), Bulk Cargo Vessel, or Flat Rack Container options.
- Documentation & Spares: Complete export docs (B/L, Invoice, Packing List, Certificate of Origin) and bundled fast-wear spare parts.
FAQ
Q1: What materials are used for the dump box to resist abrasive mining cargo?
A: We construct the cargo box using high-strength T700 steel or optional HARDOX wear-resistant plates, specifically selected to prevent denting and wearing when hauling sand, rocks, and aggregate under off-road conditions.
Q2: What is the spec of the hydraulic lifting cylinder, and how is stability managed on uneven terrain?
A: We integrate genuine HYVA FE/FC series cylinders with diameters ranging from 191mm up to 214mm depending on axle counts. The system includes anti-tilt sensors that adjust lifting speeds automatically on slopes under 15° to avoid rollover risks.
Q3: How often does the hydraulic system require regular maintenance?
A: Routine visual checks on fluid levels and line seals are recommended every 500 working hours, while full hydraulic system servicing is scheduled every 3,000 working hours.
Q4: Can axle brands, leaf springs, and payload dimensions be customized for regional transport laws?
A: Yes. We offer 2-axle to 6-axle configurations, customizable body lengths (8500mm to 11500mm), FUWA/BPW axles, and export-grade leaf spring options (100mm12mm12 layers) to align with local Gross Vehicle Weight limits.
Q5: What anti-corrosion coating process is applied to prevent rust during sea freight and harsh weather?
A: Every chassis undergoes automated shot blasting, an electrophoretic dip coating, an anti-corrosion primer, and a thick polyurethane topcoat engineered for a 10+ year surface protective lifespan.
Q6: Do you supply replacement parts if hydraulic or mechanical components get damaged on site?
A: Yes. Original OEM replacement parts-including sealed hydraulic lines, pump assemblies, JOST landing gear components, and brake valves-are supplied directly from our factory inventory.
Q7: What safety features are integrated into the chassis and braking system?
A: The main beam features a 500mm Q345B steel through-beam structure with 14mm/16mm flange plates, complemented by dual-chamber air brakes with a 451 air tank and optional ABS systems.
