The four-post-style lift is also called a drive-on lift automatic parking, using two ramps which are supported by the posts. They also tend to cost more than two-post versions because of the extra material and mechanics. But an advantage is that many four-post hoists only require a 115-volt power supply. A four-post, drive-on hoist can weigh 1,700 pounds or more. You won’t be moving that by yourself unless you own a forklift.
All the two-post hoists require a 220-volt, single-phase power supply with a minimum of a 30-amp circuit. Another advantage to four-post lifts is that some versions offer optional casters that make the hoist portable in the shop.
Four-post floor to floor lifts are most often used when additional vehicle storage is desired. Even with an 8-foot ceiling, it is possible to stack two cars. While the post height will probably clear an overhead garage door when open, the upper vehicle must also be able to clear the door. The typical muscle car is somewhere between 50 and 55 inches tall. Unless you are one of the few car crafters with a vehicle that doesn’t leak, you’ll also want to invest in a drip pan to protect the lower car.
The third version of vehicle lift is the scissor car elevator. This style can either be a drive-on or four-arm-style hoist. The scissor lift is most commonly used as a midlift-style hoist. There are also scissor-style hoists that can lift the car high enough to work underneath while standing upright.
Once you own a hoist, the fun has just begun. You’re also going to need a high-quality hydraulic trans jack and some way to get that monster 4L80E up on the trans jack. You’ll also need at least two tall, sturdy, adjustable stands to support the rear axle or exhaust system while you work under your hoist. Finally, you’re going to need a nice, big dry-erase calendar where all your friends can choose dates and times when they’ll want to use your hoist.
