Product Brief and Product Content Introduction

The Axis-type Transport Semi-trailer (Model: AXT-1600) is a professional heavy-duty solution engineered for ultra-heavy and oversize cargo transport, tailored for industries like energy, infrastructure, and heavy manufacturing. It features a modular 16-axis design (8×2-axle units) that disperses load evenly across axles, enabling safe transport of 100-150 metric ton cargo (e.g., wind turbine nacelles, tunnel boring machines, prefabricated bridge beams) while complying with global road load limits (≤12 tons/axle). Equipped with a hydraulic synchronous control system (for steering/lifting) and a low-profile anti-slip platform, it balances maneuverability, stability, and efficiency. Compatible with 400+ HP heavy-duty tractors (Sinotruk HOVA, Volvo FH16, Daimler Actros) via a 90# kingpin (SAE J844), this semi-trailer meets ECE R13 (braking) and EU STGO (oversize cargo) standards, making it a reliable choice for global clients needing specialized 大件 transport.

Axis-type Transport Semi-trailer (Model: AXT-1600) adopts a modular 16-axis configuration that delivers flexible load distribution and adaptability. It consists of 8 independent 2-axle units (total 16 axles), each made of forged 20CrMnTi alloy steel (axle shaft) and high-strength cast steel (axle housing) for resistance to bending under heavy loads. Each axis unit supports ±45° synchronous steering and 50-300 mm hydraulic lifting-controlled via a centralized system-to navigate narrow construction roads (reducing turning radius by 30% vs. fixed-axis trailers) and adjust platform height for loading docks or overpass clearance. This modular design also allows on-site reconfiguration (e.g., adding/removing 2-axis units) to match cargo weight, eliminating the need for multiple specialized trailers.

Axis-type Transport Semi-trailer (Model: AXT-1600) features a high-strength low-profile frame and platform optimized for oversize cargo. The main frame uses Q960 ultra-high-strength steel (400×200×12×16 mm section size) with CO₂ gas-shielded welding (seamless joints), ensuring structural rigidity for 150 metric ton max static load. The flat cargo platform (10 mm thick 65Mn manganese steel) has a low unloaded height of 0.8 m-minimizing total cargo height to avoid height restrictions-and is coated with anti-slip paint to prevent cargo sliding during acceleration/braking. The frame undergoes hot-dip galvanizing (Zn coating ≥100 μm) + double-layer epoxy spray, resisting corrosion from rain, mud, and industrial debris for 10+ years.

Axis-type Transport Semi-trailer (Model: AXT-1600) is powered by a high-performance hydraulic control system for precise axis operation. It offers two power sources: a tractor PTO (1000 rpm) for on-road transport, or a built-in 25 HP diesel hydraulic pump (200L oil tank) for off-grid loading (e.g., wind farms). The system operates at 28 MPa working pressure, driving double-acting hydraulic cylinders (140 mm bore, 300 mm stroke) per axis unit. Control is via an IP67 waterproof wireless remote (100-meter range) or wired handheld controller, with ±5 mm synchronization accuracy for steering/lifting-critical for aligning with cranes during cargo loading or navigating curved roads with oversize cargo.

Axis-type Transport Semi-trailer (Model: AXT-1600) boasts road-compliant dimensions and robust load-bearing capacity. Its overall length is 24.0 m, width 3.2 m (within EU/China oversize cargo width limits), and wheelbase (between 2-axle units) is 1.8 m-ensuring stable weight distribution across all 16 axles. The rated payload is 120 metric tons (150 metric tons max static load), with each axle bearing ≤12 tons (complying with EU ≤11.5 tons/axle and China ≤10 tons/axle for special transport). The 350 mm ground clearance (adjustable via hydraulic lifting) allows passability on uneven construction-site roads, while the 8.5 ton empty weight balances load capacity and tractor fuel efficiency.

Axis-type Transport Semi-trailer (Model: AXT-1600) ensures safe heavy-load operation with advanced running gear and braking systems. It uses 16 wide-base radial tires (445/65R22.5, load index 160/158) that reduce ground pressure to ≤70 kN/axle-protecting highway pavements from damage. The braking system features 450 mm diameter pneumatic disc brakes (superior heat dissipation vs. drum brakes for long downhill hauls) paired with EBS (Electronic Braking System) and ABS (ECE R13-certified), preventing wheel lock during emergency stops on wet or dusty roads. A spring-loaded mechanical parking brake (acting on all axles) secures the trailer firmly when parked, even with 120 metric ton cargo.

Axis-type Transport Semi-trailer (Model: AXT-1600) integrates comprehensive safety and auxiliary features to mitigate transport risks. Wireless load sensors (mounted on each axis unit) display real-time axle loads on the remote controller, alerting operators if loads exceed 12 tons/axle (preventing overloading). An emergency stop button (on the trailer frame and remote) instantly cuts off hydraulic power, while a backup manual pump allows axis lifting/steering if the main system fails. Fifteen 50-ton D-type rings (mounted on platform edges) secure cargo with steel cables, and LED warning lights (front/side/rear) + "OVERSIZE CARGO" signs (English/local language) enhance visibility for other vehicles.
