I. Robust and Durable Structural Design
Made of high-quality high-strength alloy steel with special heat treatment. Key structural parts are thickened to withstand heavy vertical loads and strong impact forces under complex conditions, ensuring long-term service life without deformation.
II. Precise and Flexible Connection Mechanism
Unique saddle design allows close cooperation with standard tractor specifications. Features rapid positioning and high-precision guiding devices for smooth connections even in non-ideal road conditions.
III. Excellent Buffering and Shock Absorption
Equipped with high-performance rubber buffer pads to effectively absorb vibrations from road bumps, protecting both the tractor frame and fragile cargo.
IV. Convenient Operation and Maintenance
Ergonomically designed handle reduces driver labor intensity. The reasonable structural layout allows for quick disassembly and easy component replacement.
| Category | Specifications & Descriptions |
|---|---|
| Size Options | No. 90: 90mm diameter, load capacity 30-150 tons (heavy-load engineering). No. 50: 50mm diameter, load capacity 20-150 tons (urban logistics & distribution). |
| Functionality | Single-action: Simple connection/separation for general goods. Double-action: Rotatable or lifting saddle for special scenarios like airport/port transfer. |
| Processing | Cast: High integrity for huge loads. Forged: Compact internal structure for high-end trucks. Welded: High flexibility for customized needs and lower maintenance costs. |
| Height | Fixed height (130-260mm) or Adjustable/Lifting types for varying trailer heights. |
| Swing Angle | Single-axis: 14°-15° forward/backward swing for high-speed stability. Double-axis: Swings in all directions; ideal for specific low-speed applications. |
| 1. Preparation | Verify model matching; prepare torque wrenches, jacks, and spirit levels; select flat site; inspect components for cracks. |
| 2. Installation Steps | Position tractor; install base to frame (initial tighten); hoist main body; adjust levelness; final tighten bolts in crisscross diagonal pattern. |
| 3. Usage Methods | Align traction pin; reverse until "click" lock; check engagement status; monitor for abnormal noise during transit. |
| 4. Precautions | Strictly follow torque values; conduct monthly inspections; overloading is strictly prohibited. |
A: Our fifth wheels are primarily constructed from high-quality high-strength alloy steel, often undergoing special heat treatment processes to enhance hardness, toughness, and durability.
A: The No. 50 (50mm pin) is ideal for medium and light-duty urban logistics (20-150 tons), while the No. 90 (90mm pin) is designed for heavy-duty, long-distance transportation (up to 150+ tons).
A: Yes, we offer fixed-height specifications (typically 130-260mm) as well as adjustable lifting-type fifth wheels that can adapt to semi-trailers of different heights.
A: Welded fifth wheels offer high production flexibility for customization, lower investment costs as they don't require complex molds, and easier maintenance since damaged parts can be individually repaired or replaced.
A: A comprehensive inspection should be conducted at least once a month. This includes checking the connection parts, locking mechanism, and wear condition, especially after driving on rough roads.
A: Yes, we offer full OEM/ODM services, allowing customers to use their own logos or request specific design modifications to meet unique operational requirements.
