Roll cages are essential safety structures installed inside a vehicle's passenger compartment to safeguard occupants in the event of a rollover accident. They act as a protective frame by absorbing impact and preventing the car's roof and pillars from caving in.
Important features:
- Material: Roll cages are typically constructed from high-grade Chromoly steel tubing, known for its exceptional strength-to-weight ratio and excellent resistance to bending and deformation during a crash.
- Design: Roll cages come in various configurations, offering different levels of protection depending on your needs. A basic roll bar protects the driver's head, while a multi-point cage provides a complete safety cell encompassing the entire passenger compartment.
- Main Hoop: The main hoop forms the core of the cage, typically positioned behind the driver's seat and extending upwards to protect the head.
- Door Bars: Door bars add side-impact protection by running along the sides of the car, following the door openings.
- Diagonal Bars: Diagonal bars further enhance structural rigidity by connecting the main hoop to the down bars and door bars, creating a triangulated framework.
- Mounting: Roll cages can be bolt-in (easier to install but less secure) or weld-in (offering superior strength but requiring professional installation).
