This entry from Bendpak is another portable-style car lift with a decent lifting capacity. It has a weight capacity of up to 6,000 pounds, which is not too shabby for a device that measures 81-inches long by 40-inches wide.
This lift also has electrical power delivered to a motor. That motor is a single-stage, 220-volt model that packs quite a kick. It can raise the lifting platform from floor height to the maximum lift height in around 45 seconds.
