Semi-trailer Fifth Wheel: The Key Connecting Hub for Efficient Transportation
| Robust Structural Design | Made of high-quality alloy steel with special heat treatment. Key parts are thickened to withstand high vertical loads and strong impact forces under complex conditions, ensuring durability without deformation. |
| Precise Connection | Unique saddle design fits various tractor specifications. Features rapid positioning and high-precision guiding devices for smooth connection even on non-ideal road conditions. |
| Shock Absorption | Equipped with high-performance rubber buffer pads and damping devices to absorb vibrations from road bumps, protecting the vehicle frame and cargo safety. |
| Easy Maintenance | Ergonomic handle design for light operation force. Reasonable layout allows for quick disassembly and replacement of components using standard tools. |
| Classification | Detailed Specifications |
|---|---|
| Size Type | No. 90: 90mm diameter, 30-150 tons load. For heavy-duty long-distance transport. No. 50: 50mm diameter, 20-150 tons load. For urban logistics and light-duty trailers. |
| Function | Single-action: Simple connection/separation for regular tasks. Double-action: Saddle rotates or lifts, ideal for specialized cargo transfer like port containers. |
| Processing | Casting: High strength and integrity for heavy loads. Forging: Compact internal structure, stable quality. Welding: High flexibility for customized needs and cost-effective maintenance. |
| Height | Fixed: Range 130mm-260mm. Adjustable: Lifting-type for port terminals or air suspension (ECAS) compatible systems. |
| Swing Angle | Single-axis: Swings forward/backward (14°-15°). High stability for highway transport. Double-axis: Swings in four directions. Suitable for specific terrain requirements. |
Step 1: Preparation - Verify model matching, prepare torque wrenches and jacks, and select a flat site.
Step 2: Base Installation - Align base holes with the frame, insert bolts, and initially tighten.
Step 3: Main Body Mounting - Hoist the fifth wheel body, check alignment, and insert all connecting bolts.
Step 4: Tightening - Use a torque wrench in a diagonal pattern to ensure even pressure and horizontal levelness.
