What does the cross-ramming technique primarily involve?

The cross-ramming technique primarily involves using a hydraulic ram to push off the opposite door post. This method is effective in creating an escape route in a vehicle during a rescue operation, particularly when dealing with a passenger vehicle that has been involved in a crash. By applying force to the door post, the technique allows rescuers to create sufficient space to free trapped occupants without causing further injury.

The use of a hydraulic ram is critical in situations where manual strength is inadequate due to the structural integrity of the vehicle or the severity of the crash. This technique not only increases the efficiency of rescue efforts but also helps preserve the safety of both the victims and the rescuers by minimizing the risk of structural collapse during the extrication process.
