hydraulic rescue tool, portable and battery powered hydraulic assembly for hydraulic rescue tools

摘要

the invention relates to a portable and battery powered hydraulic assembly (2) for hydraulic rescue tools, in particular for spreading or cutting tools, as well as a rescue tool equipped with such a set. the hydraulic assembly (2) includes at least one hydraulic pump (18), a hydraulic tank (25), an equalizer device (26) for hydraulic fluid, a hydraulic control valve (28) for manual use, an electromechanical interface (15 ) for coupling and uncoupling, as needed, at least one battery (16), a mechanical-hydraulic interface (4) to connect a hydraulic tool (3) and an electric motor (17) operable by the battery's electrical power (16) to supply the hydraulic pump (18). the electric motor (17) is in the form of a disc motor (19), whose axial length (22) runs parallel to the longitudinal axis of its output axis (21) is less than its external diameter (23).
