  • Hydraulic rescue system
    Patent number: 6634173
    Abstract: A hydraulic rescue system comprises a fluid reservoir, a pump assembly having a plurality of pump modules, and a manifold assembly having a corresponding number of manifold modules. Each pump module includes an input port for drawing hydraulic fluid from the fluid reservoir and an output port for supplying hydraulic fluid under pressure to a hydraulic rescue tool. Each manifold module includes a fluid circuit that is adapted to fluidly connect the output port of one of the pump modules with a hydraulic rescue tool. A PTO adapter is connected to the pump assembly and is operably connectable to a PTO shaft of a vehicle transmission for operating the pump modules. In this manner, a number of different hydraulic rescue tools can be operated simultaneously with full pressure from the pump assembly.
