They are often used in workshops and offer a balance between power and portability. Electric pulling machines are generally less powerful than hydraulic machines but still capable of handling a wide range of repair tasks.
- Slide Hammer Pulling Machines⁚ These machines utilize the principle of inertia to generate pulling force. A slide hammer, also known as an impact hammer, is used to strike a pulling head attached to the damaged panel. The impact generates a force that pulls the panel back into its original shape. These machines are particularly effective for removing dents and creases, often used in conjunction with other pulling techniques.
- Weld-On Pulling Machines⁚ These machines are designed for pulling panels that have been welded to a frame or other structural components. They use a specialized welding process to attach pulling arms to the damaged panel, allowing for controlled pulling and straightening. Weld-on machines are typically used for more complex repairs and require specialized skills and knowledge.
- Frame Straightening Machines⁚ While not directly pulling body panels, these machines are crucial for restoring the structural integrity of a vehicle’s frame. They utilize a combination of pulling, pushing, and clamping mechanisms to straighten bent or damaged frames, ensuring proper alignment and safety.
Choosing the right type of car body pulling machine depends on factors such as the severity of the damage, the size and weight of the vehicle, and the available resources. It’s crucial to consult with experienced automotive repair professionals to determine the most suitable machine for your specific needs.
