What is the principle of using a hydraulic spreader for vehicle extraction?

The principle of using a hydraulic spreader for vehicle extraction is based on the ability to exert high forces to separate or spread the vehicle's structure. Hydraulic spreaders are specifically designed to apply significant force, which allows rescuers to create space and access trapped victims within a vehicle. This is particularly important in rescue scenarios where the vehicle's structure may be compromised or twisted, posing a risk to the occupants.

By using hydraulic spreaders, responders can manipulate the vehicle's frame to expand or separate parts of the car, enabling safe access to individuals trapped in the wreckage. This capability is essential in facilitating timely extrication and ensuring that rescue operations can be conducted effectively and efficiently.
