Brief description
Hydraulic cutters are specially designed rescue equipment for cutting bodywork parts.
They are used for rescuing trapped or enclosed accident victims.
Driven by a hydraulic power unit it is possible to cut door and roof pillars, posts and sills etc.
with the cutters.
The speed of movement of the shearing blades is controlled by the greater or lesser degree
of force applied to the pushbutton on the handle. The maximum cutting force is only
applied when the pushbutton is fully depressed.
