Chain Puller Big Challenge Dent Puller

A chain-based dent puller is a heavy-duty collision repair tool used for pulling large, deep dents by anchoring the vehicle and using a boat winch or come-along for high-pressure pulling. Effective for deep body creases, this method uses welded shims or chains attached to high-strength glue tabs, often supported by a tower for leverage on side panels or fenders

DIY High-Power Puller: A DIY tower with a boat winch, 1-1/8 box tubing, and a mesh plate can be built for under $100 to handle severe collision damage.
Professional Systems: Systems like the Autorobot Smart Puller or 10-ton floor machines are used for massive damage, often requiring anchoring the car's frame.
Process: The technique involves welding shims to the dented area (or using strong glue tabs) and using chains and a winch to apply slow, controlled pressure to restore the panel shape.
Versatility: These systems can be used on side panels, fenders, and quarter panels, with the tower often supported by the tire.
Alternatives: For less severe damage, slide hammers (approx. 6 lbs to 10 lbs) with various attachments are used.
