Rear Dump Semi Trailer
The Rear Dump Semi Trailer (also known as a Rear Tipper Semi Trailer, End Dump Semi Trailer, Hydraulic Rear Unloading Dump Trailer, or Heavy-Duty Back-Tipping Cargo Semi-Trailer) is the foundational heavy-duty self-unloading transport vehicle engineered for high-efficiency bulk material handling. Designed specifically for mining, quarry operations, civil construction projects, earthmoving, aggregate distribution, sand/gravel transit, ore hauling, and bulk infrastructure materials, this trailer relies on an elevated hydraulic tipping design to discharge cargo quickly through a top-hinged automatic tailgate. Constructed on a high-tensile structural steel main chassis (Q345B/Q550/T700) using automated submerged-arc welding, it is paired with a heavy-duty rectangular or corrugated steel cargo box with high impact resistance. Powered by a front-end telescopic hydraulic hoist system (HYVA cylinder assembly), it offers superior tipping leverage, maximum angle of inclination for stick-free discharge, and low center of gravity during transit. Outfitted with 2, 3, or 4 heavy-duty commercial axles (13T/16T/20T FUWA, BPW, STEYR, or AQ axles), 10/11-leaf mechanical spring or heavy bogie suspension, and a dual-line pneumatic braking system with WABCO emergency relay valves, this rear dump trailer delivers long-term frame durability, rapid dock unloading cycles, supreme anti-impact performance, and high fleet return on investment. Fully certified under ISO9001, CCC, CE, and SGS standards.

Key Structural & Performance Features
1. Front-Mounted HYVA Hydraulic Cylinder System
- Optimized Lifting Efficiency: Outfitted with a premium front-mounted HYVA multi-stage telescopic hydraulic cylinder system that provides maximum tipping leverage, smooth lifting progression, and reduced hydraulic oil pressure spikes.
- High Tipping Angle Discharge: Achieves a steep 45° to 55° dump inclination angle, allowing rapid, complete clearance of sticky clay, wet sand, crushed stone, and heavy ore without material residue hanging up in the box.
- Automatic Tailgate Locking Mechanism: Integrated top-hinged heavy-duty steel tailgate equipped with mechanical link locks and pneumatic safety latches that open automatically during tipping and seal tight upon lowering.
2. Heavy-Duty Reinforced Cargo Box & Chassis Frame
- 8mm Floor & 6mm Side Steel Construction: Built using high-impact 8mm bottom floor plate and 6mm side wall steel sheet to absorb high drop impacts from excavators, wheel loaders, and heavy stone dumping without dishing.
- Submerged-Arc Welded Mild Alloy Main Frame: Engineered with deep I-section main beams fabricated from 16Mn / Q345B mild alloy steel via automated submerged-arc welding processes to guarantee structural alignment and eliminate torsional frame deformation under max payload tipping.
- Dense Interlocking Crossmember Grid: Mild alloy Q235 crossbeams are placed at short intervals beneath the floor plate to distribute heavy point loads and prevent floor sagging under 45-ton payload stress.
3. Commercial Running Gear & Severe-Duty Braking Safety
- 13T/16T Heavy Commercial Axles: Fitted with 3 commercial axles (FUWA, BPW, STEYR, or AQ) rated for 13-ton capacity each, offering long life cycles and worldwide spare parts availability.
- Heavy-Duty 11-Leaf Mechanical Spring Suspension: 11-piece heavy-duty leaf spring packs combined with heavy equalizer rocker arms dampen dynamic shocks from rough unpaved mining haul roads and construction sites.
- WABCO Air Braking & Relay Protection: Dual-line pneumatic brake system equipped with a WABCO emergency relay valve, T30/30+T30 spring brake chambers, and a reliable parking brake to ensure instant braking response and maximum safety during tipping and road transit.
Commercial & Logistics Terms
- Shipping & Delivery: Shipped via Ro-Ro vessel, Bulk Cargo vessel, or stacked in SKD format to optimize international ocean freight costs.
- Warranty Coverage: 3-Year structural guarantee on the main chassis frame; 1-Year warranty covering axles, landing gear, hydraulic cylinder assembly, and braking valves.
- Payment Terms: 30% T/T deposit, 70% balance paid prior to dispatch; irrevocable L/C at sight accepted.
