Towing is a vital service, and rollback trucks are the workhorses of the industry. Understanding how to effectively and safely secure vehicles onto a rollback requires knowledge of various components, including the crucial pivot mounts. This guide will walk you through the process of making pivot mounts for your rollback truck, emphasizing safety and best practices.
Understanding Pivot Mounts: The Foundation of Secure Towing
Pivot mounts are the lynchpin of a rollback's ability to load and unload vehicles. These robust mechanisms allow the wheel lift to pivot, accommodating various vehicle sizes and wheelbases. Improperly installed or fabricated pivot mounts can lead to accidents and costly repairs. Therefore, understanding their function is paramount before undertaking any construction or modification.
Key Components of a Pivot Mount System:
- The Base Plate: This is the sturdy foundation that is securely bolted to the rollback's bed. It provides the anchoring point for the entire pivot system.
- The Pivot Pin: A strong, precisely sized pin that allows the wheel lift to rotate. This pin experiences significant stress and must be able to withstand heavy loads.
- The Wheel Lift Connection: This is the portion of the mount that connects directly to the wheel lift assembly. It should be designed for smooth, controlled movement.
- The Locking Mechanism: This essential component ensures the wheel lift remains securely in place during transport. This might involve pins, latches, or hydraulic locking systems.
Building Your Own Pivot Mounts: A Step-by-Step Guide (With Cautions!)
Disclaimer: Building your own pivot mounts requires significant fabrication skills, welding expertise, and a thorough understanding of engineering principles. Improperly constructed mounts can result in serious injury or damage. If you lack the necessary skills and experience, it is strongly recommended to consult a qualified professional or purchase pre-fabricated components.
This section outlines a simplified approach, and specific materials and dimensions will need to be adapted based on your rollback truck's design and the intended vehicle capacity.
Materials (Example):
- Heavy-duty steel plates (thickness will depend on the load capacity)
- High-strength steel pivot pins
- Welding equipment (MIG welder recommended)
- Bolts, nuts, and washers (appropriate grade and size)
- Locking mechanism components (latches, pins, etc.)
Steps (Conceptual Outline – Consult Engineering Plans):
- Design and Planning: Carefully design your pivot mounts, considering the weight capacity, dimensions of your rollback bed, and the range of vehicle sizes you'll be towing. Create detailed drawings.
- Fabricating the Base Plate: Cut and shape your steel plates according to your design. Ensure the base plate is strong enough to handle the anticipated loads.
- Creating the Pivot Point: Drill precisely sized holes for the pivot pin. Ensure the alignment is perfect to prevent binding or stress concentration.
- Attaching the Wheel Lift Connection: Weld or securely bolt the connection point for the wheel lift to the base plate. This connection should allow smooth rotation.
- Integrating the Locking Mechanism: Install the chosen locking mechanism to ensure the wheel lift is securely held in place during transit.
- Welding and Reinforcement: Use appropriate welding techniques to create strong, reliable welds. Reinforce any areas prone to stress.
- Testing and Inspection: Before using the newly fabricated pivot mounts, conduct thorough testing under controlled conditions with appropriate safety measures. Verify the strength and stability of the entire system.
Maintaining Your Pivot Mounts: Extending Their Lifespan
Regular maintenance is critical for the longevity and safety of your pivot mounts. This includes:
- Regular Inspection: Visually inspect the mounts for signs of wear, damage, or cracks.
- Lubrication: Keep the pivot pin properly lubricated to reduce friction and wear.
- Tightening Bolts: Periodically check and tighten all bolts and fasteners to ensure they remain securely fastened.
- Repair or Replacement: Address any damage or wear promptly. If a component is beyond repair, replace it with a high-quality equivalent.
By following these guidelines, you can improve your understanding of pivot mounts and potentially fabricate them (with caution and professional guidance). Remember, safety should always be the top priority when working with heavy machinery and potentially dangerous components. Improper installation can lead to serious accidents. If you are unsure about any aspect of this process, seek professional assistance.
