Abstract:
The present invention is directed to a wheeled lifting device that is configured for positioning between an extended configuration and a retracted configuration and adapted for attachment to a wheeled or non-wheeled device. In the extended configuration, the wheeled lifting device is configured to allow for multi-directional movement of the wheeled or non-wheeled device. The wheeled lifting device may include an extension mechanism and at least one multi-directional wheel, where the extension mechanism is configured to move the wheeled lifting device between the retracted configuration and the extended configuration. The extension mechanism can include a mechanical mechanism, a hydraulic mechanism or a pneumatic mechanism.
