Abstract (en)

[origin: WO9900553A1] A tool (1) serving for manually handling a well cover (22). The tool is constructed around a trilateral grating with a first, second, and third bar (3, 4, 5). At the top, the first bar (3) is provided with a handle (9), and at the bottom, a cross axle (10) with a wheel (11) at each end is fitted at the joint between the first and third bar (3, 5). The tool furthermore comprises a rocker arm (13) tiltable around a bearing (12) extending mainly parallel to the axle. Two lifting keys (28) for detachably engaging with corresponding keyholes (35) in the cover are placed on the outer part of the rocker arm with mutual spacing in the longitudinal direction. The tool furthermore has a stop (19) for limiting the turning of the rocker arm. In use, the tool is used firstly as a long crowbar, for breaking the cover free of the curb using little strength, secondly as a lifting tool for lifting the cover, and finally as a trolley for transporting the cover away from the curb. The tool has a simple construction, it is easy to use and affects the operator with less physical load than known so far.
