My BendPak 4 post car lift has a rail that runs down the inside of each runway. This is intended to accommodate their rolling hydraulic transmission jack.

I decided to make a small gantry that rolls down the length of the lift, with an I-beam trolley that rolls sideways. Sideways trolley travel distance is a modest 28", but enough to load or unload a cart. I can back my pickup truck under the end, lower the hoist a bit, and pickup whatever I want to unload. Since the BendPak itself provides all the lifting, there is no need for a chain hoist, etc. Only a few lifting straps and hooks are necessary.

The gantry wheels have a stated load capacity of 660 lbs. each, but I probably won't be lifting more than a few hundred lbs. with it. When rolling it with a load, I'll keep the trolley over toward the side with two casters. Four casters would have added to the capacity, which I don't need.

The lift will sit flat on the ground with the trolley in place. Any car with 4" or more undercarriage clearance can pass over it. The gantry lifts off in seconds if a really low slung car has to go up top.

Based on some suggestions I received, I scrapped the above gantry and fabricated a replacement using heavier casters and a cross beam that goes all the way across.
