In a dash displacement, the dash is pushed forward by either a mechanical high lift jack or what other device?

Explanation:
Dash displacement requires a tool that can deliver a strong, straight, controlled pushing force to move the dash forward and create space for the occupant. A hydraulic ram fits this role because it provides a steady hydraulic push with a predictable stroke, allowing the rescuer to control how far and how quickly the dash is moved. While a mechanical high lift jack can also push, the hydraulic ram is the other device specifically used for this purpose because it offers precise, linear force without relying on manual effort. A hydraulic jack is mainly for lifting and may lack the controlled pushing action, and a winch or sledgehammer does not provide the direct, controlled forward movement needed and can introduce unsafe or unpredictable motions.
