Straight Beam Rear Tipping Semi Trailer

1. Straight Beam Frame System (Core Structure)

Frame Material: High-strength low-alloy steel (Q345B/Q690), with longitudinal beams (main load-bearing components) featuring a fully straight structure (no curved or variable cross-sections) for uniform weight distribution.

Longitudinal beam thickness: 10–16 mm (10–12 mm for 3-axle models; 14–16 mm for 6-axle heavy-duty models).

Crossbeam material: Q235 steel, thickness 8–10 mm; spacing 300–400 mm (evenly arranged to form a grid-like load-bearing surface, avoiding local stress deformation).

Structural Performance:

Torsional resistance: ≥ 250 kN·m/rad (ensures stability under 60-ton heavy loads on uneven roads).

Load-to-weight ratio: 7–8:1 (e.g., 3-axle model: 30-ton payload vs. 4-ton curb weight), 15–20% higher than variable-cross-section beam trailers.

Anti-corrosion Treatment: Shot blasting (rust removal grade Sa2.5) + epoxy primer + industrial topcoat; salt spray resistance ≥ 1,500 hours (suitable for high-dust mines and coastal high-humidity environments).

2. Rear Tipping Hydraulic System

Drive Configuration:

Hydraulic cylinders: 2–4 double-acting cylinders (brand options: Bosch Rexroth, Chinese Haiwo); 2 cylinders for 3-axle models, 4 parallel cylinders for 6-axle models (ensures balanced lifting).

Working pressure: 18–22 MPa (sufficient to lift full loads without pressure loss).

Tipping Performance:

Tipping angle: 35°–45° (35°–40° for 3-axle; 40°–45° for 6-axle) – ensures ≤1% residue for sticky materials (e.g., wet coal, construction muck).

Tipping time: 30–50 seconds (from horizontal to max angle); lowering time: 20–35 seconds (with buffer control to reduce chassis impact).

Safety Features:

Hydraulic lock: Maintains position for ≥48 hours if the system loses pressure (prevents accidental lowering during unloading).

Pressure relief valve: Cuts off power when pressure exceeds 24 MPa (protects cylinders from overload damage).

The Straight Beam Rear Tipping Semi Trailer is a heavy-duty bulk transport vehicle engineered for "overload resistance + efficient unloading"-its fully straight longitudinal beam frame solves the pain points of traditional variable-cross-section beam trailers (uneven load distribution, easy deformation under heavy loads). Its core value lies in **four key strengths**: strong load-bearing (load-to-weight ratio 7–8:1, 15% higher than industry average), complete unloading (35°–45° tipping angle, ≤1% residue), long durability (Q690 steel frame + wear-resistant cargo box, service life ≥5 years), and wide adaptability (fits coal, gravel, ore, and construction muck). Available in 3-axle (30–40 tons payload) and 6-axle (50–60 tons payload) models, it complies with global standards (China GB 1589, EU 1072/2009, US DOT FMVSS 121) and integrates hydraulic safety locks, anti-roll sensors, and anti-corrosion treatments. By reducing transport costs by 12% and maintenance frequency by 30%, it becomes a core equipment for global trade clients in heavy industry and infrastructure.

Product Details

1. Straight Beam Rear Tipping Semi Trailer: High-Strength Straight Beam Frame System

The Straight Beam Rear Tipping Semi Trailer's straight beam frame is the foundation of its heavy-load capability, ensuring uniform stress and low deformation. It uses Q345B/Q690 high-strength low-alloy steel for longitudinal beams: 10–12 mm thickness for 3-axle models (30–40 tons payload) and 14–16 mm thickness for 6-axle models (50–60 tons payload). The beams are formed by integral rolling (no welding seams) and connected to Q235 steel crossbeams (8–10 mm thickness, 300–400 mm spacing) via rigid welding-creating a "grid-like load-bearing surface" that distributes 60 tons of concentrated load evenly (local stress ≤250 MPa, far below material yield limit). The frame's curb weight is only 4–8 tons (3-axle: 4–5 tons; 6-axle: 7–8 tons), achieving a 7–8:1 load-to-weight ratio-meaning it can carry 7–8 tons of cargo per ton of self-weight, 15–20% higher than variable-cross-section beam trailers. For anti-corrosion, the frame undergoes shot blasting (Sa2.5 grade) + epoxy primer + industrial topcoat-salt spray resistance ≥1,500 hours, withstanding coal dust erosion in mines and saltwater humidity in coastal areas.

2. Straight Beam Rear Tipping Semi Trailer: Efficient Rear-Tipping Hydraulic System

The Straight Beam Rear Tipping Semi Trailer's hydraulic lifting system ensures fast, stable unloading-critical for heavy bulk materials. It adopts a tractor PTO-powered hydraulic circuit (working pressure 18–22 MPa) with 2–4 double-acting cylinders (brand options: Bosch Rexroth, Hengli). 3-axle models use 2 cylinders, completing full tipping (35°–40°) in 30–40 seconds-enough to empty 12 m³ of wet coal without residue. 6-axle models use 4 parallel cylinders, tipping to 40°–45° in 40–50 seconds-suitable for 16 m³ of dense ore (60 tons). The system includes three safety designs: hydraulic lock (maintains position for ≥48 hours if pressure is lost, preventing accidental lowering), pressure relief valve (cuts off power at 24 MPa to protect cylinders from overload), and buffer lowering (reduces chassis impact by 35% when the cargo box returns to horizontal). A "partial tipping" function allows stopping at any angle (10°–45°)-ideal for controlled discharge of sticky muck (avoids splashing and site cleaning time).

3. Straight Beam Rear Tipping Semi Trailer: 3-Axle vs. 6-Axle Scenario Adaptation

The Straight Beam Rear Tipping Semi Trailer offers 3-axle and 6-axle models to match short-distance agility and long-haul heavy-duty needs. The 3-axle Straight Beam Rear Tipping Semi Trailer (30–40 tons payload, 12.0–13.7 m overall length) is optimized for short-distance regional transport: e.g., mine-to-washery coal transfer (fits 3.5 m-wide mine lanes) and urban construction muck removal (navigates 4.5 m-wide city roads). It uses 12R22.5 radial tires (6 total) and mechanical leaf spring suspension (8–10 leaves/set)-cost-effective for frequent stops (≤100 km trips) and rough construction site roads. The 6-axle Straight Beam Rear Tipping Semi Trailer (50–60 tons payload, 16.0–17.5 m overall length) targets medium-long-haul bulk transport: e.g., cross-provincial ore delivery from mines to steel mills and inter-regional gravel transport from quarries to highway projects. It features 12 tires (12R22.5) + 1 optional spare, and reinforced axle brackets (BPW/SAF axles, 13 tons load rating per axle)-complying with EU/US road weight limits (≤68 tons GVW) to avoid overloading fines. Optional air suspension reduces vibration by 40%-protecting the frame during 500+ km long-haul trips.

4. Straight Beam Rear Tipping Semi Trailer: Wear-Resistant Cargo Box Structure

The Straight Beam Rear Tipping Semi Trailer's cargo box is designed for durability, withstanding abrasion from sharp materials like ore and gravel. The bottom plate uses Q690 wear-resistant steel (8–12 mm thickness)-2x more wear-resistant than Q345 steel (service life ≥80,000 km, vs. 40,000 km for standard steel). It features a "herringbone" anti-slip pattern (2.5–3 mm depth)-preventing material shifting during downhill transport (reducing brake wear by 25%). The side plates are Q345 steel (6–8 mm thickness) with 10 mm-thick steel angle reinforcements at edges-resisting impact from falling rocks (common in mines) and avoiding deformation. For sticky materials (wet clay, muck), an optional U-shaped bottom is available-eliminating right-angle corners to reduce residue to ≤0.8% (no manual cleaning needed). Removable side plates (height adjustable 1.5–2.5 m) are also optional-adapting to oversize loads like construction steel bars (converting from bulk transport to irregular cargo transport in 30 minutes).

5. Straight Beam Rear Tipping Semi Trailer: Comprehensive Safety & Durability Features

The Straight Beam Rear Tipping Semi Trailer integrates multi-layer safety devices and durability enhancements to minimize operational risks. Safety protections include: a roll angle sensor (triggers an alarm and stops tipping if the trailer tilts over 15°-preventing rollover on uneven mine roads), a dual-circuit air brake system with ABS (ECE R13 certified)-shortening braking distance by 25% on wet roads, and a rear anti-collision beam (16 mm-thick steel, 300 mm height)-absorbing impact in minor collisions. For durability, the trailer uses: high-quality axle bearings (BPW/SAF, service life ≥100,000 km), oil-lubricated kingpins (maintenance interval 10,000 km, vs. 5,000 km for dry kingpins), and stainless steel hydraulic hoses (resisting corrosion from coal dust and rain-avoiding leakage). LED side markers and ECE R65-compliant reflective strips (full-body coverage) enhance visibility at night/fog-reducing collision risks by 50%.

6. Straight Beam Rear Tipping Semi Trailer: Regional Customization & Global After-Sales

The Straight Beam Rear Tipping Semi Trailer offers targeted regional customizations and reliable after-sales support to meet trade needs. For cold regions (Siberia, Canada), optional hydraulic oil heaters (12V/24V) and anti-freeze brake chambers are available-preventing system freezing at -30°C. For tropical regions (Southeast Asia), a sunshade cover (aluminum alloy) is added to the hydraulic oil tank-reducing oil temperature by 15°C (avoiding viscosity loss in high heat). Certification support covers CE (EU), DOT (US), CCC (China), and SONCAP (Africa)-with full technical documents (material test reports, load test certificates) for customs clearance. After-sales service includes: a 24-month warranty on core components (frame, axles, hydraulic cylinders), 40+ global service centers (Germany, China, Brazil, South Africa) providing on-site repairs, and spare parts kits (brake pads, cylinder seals, wear plates) delivered within 72 hours. We also offer free operator training (hydraulic maintenance, safe tipping) to minimize downtime for trade clients.

This English product introduction fully highlights the Straight Beam Rear Tipping Semi Trailer's unique "straight beam heavy-load advantage" and addresses trade-critical needs (durability, compliance, scenario adaptation).
