Brief description
Hydraulic spreaders are specially designed rescue equipment for spreading, squeezing
and pulling. They are used for rescuing trapped or enclosed accident victims.
Driven by a hydraulic power unit it is possible to open doors, lift vehicles and other moveable
loads, push away and move vehicle parts and loads and crush tubes and pillars with the
spreaders.
The speed of movement of the spreader arms is controlled by the greater or lesser degree of
force applied to the pushbutton on the handle. The maximum spreading force is only applied
when the pushbutton is fully depressed.
