This is a 10+yr old lift system that was acquired 5 yrs ago by our family. It is in working order and was used in the garage to access the entrance into the home. We do not have original paperwork -sorry. Our engineer father, added a sturdy side platform and small wooden ramp to get onto the platform when in down position. You can see from the pictures that it will power up to 30 – 32 inch rise meeting threshold into house. It is approx. 34 in wide and 48 in deep on the platform portion. It has a turn knob for up and down. One will need to dissasemble onsite and pick up in Scarborough. Gifting. as is. Additional pictures available.
