Trolley for mounting, dismounting, and transporting a tire, wheel, or tire-wheel assembly

A trolley comprising:

• a base comprising:
• a frame having first and second longitudinal end sides, and first and second longitudinal portions between the first and second longitudinal end sides,
• a set of wheel assemblies, and
• a connecting plate;
• a hydraulic lift mounted upon the connecting plate;
• a support plate mounted upon the hydraulic lift;
• first, second, and third support arms attached to the support plate;
• and
• a lift actuator configured to alter fluid pressure within the hydraulic lift, wherein:
• the first longitudinal end side is opposite the second longitudinal end side,
• the first longitudinal portion and the second longitudinal portion diverge from each other as the first and second longitudinal portions extend in directions toward the second longitudinal end side away from the first longitudinal end side,
• the connecting plate is mounted upon top sides of the first and second longitudinal portions proximate the second longitudinal end side of the frame,
• the third support arm extends upward from the support plate,
• the first and second support arms extend away from the support plate and substantially orthogonal to the third support arm, and
• the set of wheel assemblies is arranged to keep the frame above a ground surface below the frame.
