Key Benefits
What Weld-On Winch Gives You
- Low profile design allows for easy clearance and compact installation on trailer sides
- Permanent weld-on mounting provides high structural strength and resistance to vibration
- Three-bar bracket design increases load distribution and reduces stress on the trailer rail
- Black powder coating resists abrasion and rust in outdoor and harsh transport environments
- Ratchet mechanism enables incremental tensioning of webbing straps without slippage
- Simple construction reduces maintenance needs and increases reliability in field use
- Meets federal tie-down standards for number and placement of winches on flatbed trailers
Application Scenarios
Where Weld-On Winch Is Used
- Securing heavy machinery or steel coils on flatbed trailers during long-haul transport
- Mounting on the side rails of open-deck trailers for consistent, repeatable cargo restraint
- Installing on utility and service trucks where space is limited and rigidity is critical
- Using in logistics operations requiring multiple tie-down points per load for compliance
- Integrating into custom trailer builds where permanent, low-profile winches are needed
Who It Is For
Buyers This Product Is Built For
- Flatbed trailer manufacturers building new or custom trailers
- Fleet operators upgrading or retrofitting existing trailers with reliable tie-down hardware
- Logistics companies specifying winch placement to meet federal cargo securement standards
- Truck body builders integrating winches into custom trailer designs
- Rigging distributors supplying winches for trailer and transport applications
Problems It Solves
Problems This Product Removes
- Inadequate tie-down strength due to loose or removable winch fittings on trailers
- Limited space for winch mounting on narrow or low-profile trailer sides
- Winch failure under repeated loading due to weak mounting or poor material
- Lack of compliance with federal cargo securement regulations requiring multiple tie-down points
- Rust and abrasion damage on winches exposed to weather and cargo movement
- Need for multiple separate components to achieve a secure, permanent mounting solution

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Removable bolt-on winch | The weld-on version offers higher strength and permanence but cannot be removed or relocated without cutting |
| Vertical mount winch | The side mount design saves space on the trailer side and allows easier access for the winch bar |
| Electric winch | Manual weld-on winches are simpler, require no power source, and are more reliable in remote or harsh environments |
| Snatch block with strap | The winch provides continuous tensioning and locking, while a snatch block only redirects force without holding tension |
Use Guide
How To Use And Inspect Weld-On Winch
- Weld the winch to the trailer rail using a qualified welder and proper joint design
- Ensure the winch is aligned with the direction of strap pull to avoid side loading
- Use a standard winch bar to tension the webbing strap incrementally
- Check that the ratchet engages fully and does not slip under load
- Inspect the welds and mounting bracket regularly for signs of fatigue or cracking
- Retire the winch if the body shows deformation, the ratchet fails to hold, or the coating is severely damaged

Weld-On Winch FAQ
Can this winch be installed on the underside of the trailer rail?
Yes, it can be mounted vertically on the underside of the rail, but the side mount configuration is standard for accessibility and clearance.
What is the difference between the 140mm and 110mm bracket height?
The 140mm bracket provides higher clearance above the trailer rail, while the 110mm version is lower profile for tighter spaces.
Is the winch rated for repeated heavy use?
Yes, the carbon steel construction and welded bracket are designed for repeated loading in transport and logistics applications.
Can the finish be changed to zinc plating or electrophoretic black?
Yes, custom surface finishes including zinc plating and electrophoretic black are available on request.
What is the net weight of each model?
The 140mm bracket model weighs 4.08 kg (8.97 lbs); the 110mm bracket model weighs 4.06 kg (8.93 lbs).
Can you provide custom drawings for mounting?
