HYDRAULIC UNIT FOR HYDRAULIC RESCUE TOOLS AND RESCUE TOOL EQUIPPED THEREWITH

摘要

The invention relates to a portable, battery-operated hydraulic unit (2) for hydraulic rescue tools, in particular for spreading or scissors tools, and a rescue tool equipped therewith. The hydraulic unit (2) comprises at least one hydraulic pump (18), a hydraulic tank (25), a compensation device (26) for hydraulic fluid, a manually operated hydraulic control valve (28), an electromechanical interface (15) for coupling and uncoupling as required of at least one battery pack (16), a mechanical-hydraulic interface (4) for connecting a hydraulic tool (3), and an electric motor (17), which can be operated by the electrical energy of the battery pack (16), for driving the hydraulic pump (18). The electric motor (17) is formed by a pancake motor (19) whose axial length (22) running parallel to the longitudinal axis of its output shaft (21) is shorter than its outer diameter (23).
