What is the primary function of the Paratech VSK controller?

• A. Used to control VSK rescue struts
• B. Inflate airbags
• C. Measure pressure
• D. Lock bases

Answer: (A)

The VSK controller is the handheld hydraulic control unit used to operate the VSK rescue struts. It provides the flow of hydraulic fluid from the pump to the struts and lets you control extension and retraction, including speed and stopping position, so you can position and stabilize loads safely during a rescue. It isn’t used to inflate airbags—that’s a different accessory—and it doesn’t function as a pressure gauge; pressure is monitored on dedicated gauges in the system. It also doesn’t lock bases—that mechanical step is separate from the controller’s role. In short, its primary job is to actuate and control the VSK rescue struts themselves.
