If I get the house, I will have to jack support to replace/repair foundation sills and beams/joists for the first Floor Jack 3T. All from the basement. I am intrigued (crazy?) by doing the jack supporting myself using 20 ton jacks. I think screw jacks look easier, since I wouldnt be able to do cribbing without help and it looks more complicated. I havent done this before, but am careful and follow directions well. Should I attempt or is it too dangerous? I am female and not young (but not ancient either) if this makes any difference. I could pay professionals, but then I would never learn how to do stuff myself. Advice?
But let’s dig a little deeper and investigate the biggest differences:
Capacity
The scissor jack was designed for your specific vehicle, so this type of jack, if made for a small sedan might collapse if you try lifting an SUV. Floor jacks, on the other hand, come in capacities from two tons and up, capable of lifting anything from an ATV to a bulldozer.
Durability
Because the scissor jack was designed for changing flat tires, it isn’t expected to see much use. Typically made of stamped metal, they’re just strong enough to get the job done. Floor jacks are designed for repeated and heavy usage, so they can take more abuse.
Versatility
The scissor jack was designed to accomplish a single task — changing a tire. Depending on design, it may fit lift points on your specific vehicle, and maybe only to a certain height, to get the tire a couple inches off the ground. This makes it almost useless for anything else, such as lifting a different vehicle or completing an oil change. A floor jack, on the other hand, adapts to any vehicle’s lift points and can lift high enough to get under the car.
Scissor Jack for Changing a Tire, and Not Much Else
When it comes to DIY auto repair, don’t count on the scissor jack for anything more than its intended purpose. But if you plan on attempting more substantial repairs, invest in a floor jack and jack stands, rated for the heaviest vehicle you own, keep them well-maintained and always consider your safety.
Employ Safe Lifting Practices
Before crawling under your car, remember that safety is paramount. Never put part of your body under a vehicle supported only by a jack, whether using a scissor jack or floor jack:
Block: Make sure your car is on a level surface and put the transmission in park or in gear and set the parking brake. Use chock blocks to block the wheels opposite from where you’re lifting, both in front and in back of the wheel. For example, if you’re lifting the left rear of the vehicle, put chock blocks in front of and behind the right front tire.
Lift: Use the jack to lift the vehicle to whatever height is necessary. On soft surfaces, such as dirt or asphalt, use three-quarter inch plywood to prevent the jack from sinking into the ground.
Support: Place jack-stands, preferably rated higher than your jack, under a solid part of the car, such as an axle or suspension component. Lower the vehicle onto the jack stands and shake the car to make sure it’s stable. Once you are sure your car is stable, you can remove the jack and begin work on your vehicle.
Scissor Jack and floor jacks both have their place, and both are exceptionally useful, but they can be inconvenient, if not downright dangerous, when used beyond what they are designed to do. Whether using a scissor jack or floor jack, keep it well-maintained, and use it properly. Remember these car jack tips, and you can safely work on practically anything under your car.
