Hydraulic rescue tool
Hurst Performance began to export parts to a European company, Zumro ResQtec, to avoid import duty.The hydraulic pump, attached to the tool or as a separate unit, powers a piston that pushes the blades apart with great force and spreads the seam.An extension ram consists of a piston or telescoping cylinder that extends under hydraulic pressure to exert force on vehicle structures.Rams can extend and apply directed force much further than the arms of a spreader, making them ideal for reaching deep into crushed vehicle compartments.The tools operate on the basis of the hydraulic fluid pressure of up to 720 bars (10,400 psi; 72 MPa), which must be provided from a power source.The most commonly used source is a separate power unit, small petrol (gasoline) engine connected to a hydraulic pump.These are still relatively new on the market and thus may still be somewhat immature but potentially offer many benefits over hydraulic such as but not limited to lower cost of ownership, quicker, more direct and responsive operation, decreased weight, improved portability and handling, and greater reliability.
