Abstract
A combustion-powered portable vehicle lift comprising a base, a post supported by the base, and a carriage assembly vertically shiftable relative to the post. The vehicle lift additionally comprises a combustion power system including a fuel tank and a combustion engine. The vehicle lift further comprises a hydraulic power system including a hydraulic reservoir, a hydraulic pump, and a hydraulic cylinder. As such, the combustion power system is operable to power the hydraulic power system to shift the carriage assembly relative to the post.
