Systems, methods, and apparatuses for engaging, lifting, and moving objects such as wheeled cargo trailers are provided. In one embodiment, a mobile apparatus includes a transport mechanism, a frame, and one or more lift assemblies. The lift assemblies may be adjusted using one or more attached actuators that position the lift assemblies and/or components thereof for engaging and lifting an object. The transport mechanism may be autonomously operated. A vision system may be used to locate and identify objects and/or guide the mobile apparatus into position to engage and lift the objects. An adapter for a pneumatic braking system of a wheeled cargo trailer is also provided. The adapter provides a pneumatic attachment for a pressurized air source that is separate from a glad hands connector attached to the braking system.
