I have a system that works very well for me. I pick up machines in an SUV, I always put down cardboard so the game slides easy. I have 3 steps at my front door, and each platform is about 4 feet long.
I have the Harbor Freight hydrophilic cart using the adjustable flag pole holders for the handle, so I can tilt the handles down. I also have a beat up living room coffee book table.
I back my SUV as close as I can get it to the stairs. Raise the Hydraulic cart to the proper height, and slide the game on the card board onto the lift. This is my first step. The coffee table is on the second step. I put a moving blanket on the coffee table. Set the lift to the coffee table height, and slide the machine on the coffee table.
I then take the Harbor Freight lift inside and set it about 1/2" lower then the coffee table and lock the wheels. I go outside and push the machine onto the Harbor Freight lift. Go back inside, raise the lift, install the legs and roll to position.
I don't have to pick up anything. The system is a real back saver.
