Attaching a ramp to a van often involves a secure mechanical fastening system that ensures both safety and stability during use. For a robust installation, a common method involves bolting a base plate to the van's floor, which then serves as the anchor for the ramp's bracket.
Understanding Ramp Attachment Systems
Various types of ramps, such as portable, bi-fold, or permanently mounted options, require different attachment methods. Permanent or semi-permanent installations, especially for heavier loads or frequent use, typically involve a fixed mounting system within the van. This ensures the ramp remains stable and safe for loading and unloading.
Step-by-Step Guide: Bolting a Ramp Base Plate to a Van
A reliable method for attaching a ramp involves securing a base plate to the van floor, to which the ramp's bracket is then fixed. This process ensures the ramp is stable and capable of handling its intended load.
Required Tools and Materials
To successfully attach a ramp using this method, gather the following:
- Drill
- 12mm diameter drill bit (suitable for the van's floor material)
- 4 x M10 x 60mm bolts
- 4 x Flat plate washers (for the underside)
- Wrench or socket set
- Screwdriver (appropriate for the ramp bracket screws)
- Safety glasses and gloves
- Ramp base plate
- Ramp bracket
- The ramp itself
Installation Process
Follow these steps to securely attach your ramp's base plate and bracket to the van:
- Position the Base Plate: Carefully place the ramp's base plate in the desired location on the van floor. Ensure it's correctly aligned for the ramp's operation, especially if it's a hinged ramp where the Fulcrum point is critical for smooth deployment.
- Mark and Drill Holes:
- Mark the positions for the four bolt holes. These should be precisely located through the base plate.
- Drill 4 x 12mm diameter holes through the van floor at the marked points. It's advisable to drill two holes at both ends of the base plate, close to where the ramp's Fulcrum will be. Ensure you are aware of anything beneath the van floor before drilling.
- Secure with Bolts and Washers:
- Insert the 4 x M10 x 60mm bolts through the base plate and the drilled holes in the van floor from the top.
- From the underside of the van, place flat plate washers onto the protruding bolts, followed by the corresponding nuts.
- Hand-tighten the nuts initially to hold the base plate in place.
- Screw the Ramp Bracket into Place: Once the base plate is securely bolted, screw the ramp bracket into place onto the base plate. This bracket is the direct attachment point for the ramp. Ensure the screws used here are appropriate for the bracket and base plate materials.
- Tighten All Fixings: Using a wrench or socket set, fully tighten the nuts on the M10 bolts from the underside of the van. Then, use a screwdriver to ensure that the screws securing the ramp bracket are tight so that the ramp is secure. Double-check all fastenings to prevent any movement during ramp deployment and use.
Key Considerations for Secure Ramp Attachment
When attaching a ramp, several factors are crucial for a safe and effective setup:
- Van Type and Floor Material: The type of van (e.g., cargo van, passenger van converted for accessibility) and its floor construction (steel, wood, composite) will influence the drilling and fastening methods. Reinforcement might be necessary for certain floor types.
- Ramp Load Capacity: Ensure the attachment method and materials (bolts, washers, base plate) can safely support the maximum intended load of the ramp, including the weight of the user or cargo. Refer to both the ramp and van manufacturer's specifications.
- Safety Regulations: For commercial use or accessibility modifications, be aware of any local or national safety standards and regulations for vehicle modifications and ramp installations.
- Corrosion Prevention: If drilling through the van's floor, properly seal the drilled holes with rust-preventative paint or sealant to prevent corrosion, especially for bolts exposed to the elements.
- Clearance: Check for adequate clearance beneath the van floor before drilling to avoid damaging fuel lines, brake lines, electrical wiring, or other critical components.
Different Ramp Attachment Methods
While permanent bolting is a robust solution, other methods exist depending on the ramp type and desired flexibility.
| Method | Description | Best For |
|---|---|---|
| Permanent Bolting | Base plate bolted to the van floor, ramp fixed to the plate. | Heavy-duty, frequent use, accessibility, maximum stability. |
| Quick-Release System | Uses pins or clamps to attach/detach the ramp from a fixed receiver. | Versatility, occasional use, when the ramp needs to be removed quickly. |
| Hinge-Style Attachment | Ramps with built-in hinges that directly bolt or clamp to the van's sill. | Simple, lightweight ramps, manual deployment, less permanent. |
| Clamp-On (Temporary) | Uses adjustable clamps to grip the van's rear bumper or door frame. | Portable ramps, temporary use, no vehicle modification required. |
Maintenance and Safety Checks
Regular inspection of your attached ramp system is vital for continued safety:
- Check Fasteners: Periodically inspect all bolts, nuts, and screws for tightness. Vibration from driving can loosen them over time.
- Inspect for Wear: Look for signs of wear, corrosion, or damage on the ramp, its hinges, and the attachment points.
- Lubrication: For hinged ramps, ensure the pivot points are clean and properly lubricated for smooth operation.
- Load Testing: Safely test the ramp with a representative load before full operational use, especially after installation or significant maintenance.
By following these guidelines and carefully executing the installation steps, you can ensure your ramp is securely and safely attached to your van, ready for reliable use.
