Leaf Spring Suspension Stake Fence Vehicle
The Leaf Spring Suspension Stake Fence Vehicle (also known as a Mechanical Spring Lattice Cage or Steel Spring Grid Trailer) is a high-durability, heavy-duty cargo transport semi-trailer engineered specifically for rugged regional logistics, unpaved agricultural routes, off-road mine-to-market haulage, and heavy bulk freight distribution. Equipped with a heavy-duty mechanical multi-leaf spring suspension system (featuring high-strength 10-leaf or 12-leaf spring packs and reinforced equalizer arms), it offers exceptional impact absorption, high roll stability, and dependable load distribution across all axles without relying on complex pneumatic systems. Built on an ultra-rigid Q345B/Q550 structural steel chassis welded via automated submerged-arc processes, it features an elevated multi-tiered steel lattice fence structure (wall heights from 1200mm to 2200mm) and an anti-skid 3mm or 4mm checkered steel floor deck. Supported by 2, 3, or 4 commercial heavy-duty axles (13T/16T FUWA or BPW) and a dual-line pneumatic air braking system with WABCO ABS, this trailer provides supreme structural resilience, minimal maintenance downtime, and long-term operating durability under harsh road conditions. Fully certified under ISO9001, CCC, CE, and SGS standards.

Key Structural & Performance Features
- High-Strength Mechanical Leaf Spring Suspension
Heavy Multi-Leaf Spring Assemblies: Equipped with 10-leaf or 12-leaf high-silicon steel spring packs (up to 16mm thick per leaf) designed to absorb high torsional forces, sudden impacts, and deep rut vibrations on unpaved roads.
Balanced Load-Equalizing Rockers: Inter-axle equalizer rocker arms dynamically balance load distribution across all axles during movement over uneven terrain, preventing single-axle overloading and tire scuffing.
Low-Maintenance Mechanical Design: Simple, robust mechanical construction eliminates air bag puncture risks or compressor failures, reducing maintenance costs in remote or harsh operating environments.
- High-Capacity Stake Frame & Anti-Skid Deck
Submerged-Arc Welded Main Chassis: Fabricated using Q345B/Q550 high-tensile structural steel with automated submerged-arc welding. Reinforced I-beam flange and web dimensions resist frame twisting under heavy multi-ton loads.
Multi-Tiered Lattice Stake Enclosure: Elevated steel fence walls (up to 2200mm high) provide maximum cubic capacity for high-volume agricultural produce, livestock, packaged goods, and bagged freight while ensuring cross-ventilation.
3mm/4mm Checkered Steel Deck: Features an anti-skid checkered steel floor plate supported by dense transverse crossmembers to withstand forklift loads and cargo abrasion.
- Reliable Running Gear & Safety System
Commercial Heavy-Duty Axles: Powered by 2, 3, or 4 heavy-duty commercial axles (13T/16T FUWA or BPW) paired with 12R22.5 or 12.00R20 radial tires for excellent load-bearing capacity and ground clearance.
WABCO Air Braking with ABS: Dual-line compressed air brake system equipped with WABCO ABS delivers prompt stopping response, short braking distances, and complete wheel-lock protection on wet or unpaved routes.
Perimeter Anchoring System: Side channel rails incorporate heavy-duty rope hooks, winches, and lashing rings for fast, secure attachment of protective tarpaulins over cargo.
Commercial & Logistics Terms
Shipping & Delivery: Transported via Ro-Ro vessel, Bulk Cargo vessel, or 40ft High Cube (40HQ) container (utilizing bolt-connected split-frame options) for cost-effective ocean freight.
Warranty Coverage: 3-Year structural guarantee on the main chassis frame; 1-Year warranty covering axles, landing gear, braking valves, and mechanical components.
Payment Terms: 30% T/T deposit, 70% balance paid prior to dispatch; irrevocable L/C at sight accepted.
