Safety should be the number one priority for a car mechanic. One would think that all mechanics have many years of experience of safe working practices they could employ to prevent accidents. It is surprising then, to find that many people get injured each day by collapsing cars in a garage, and this is due to not using specialist tools.
Jacks are the primary tools for preventing collapsing cars. Placed under jack points, jacks can fully support a vehicle, preventing it from slipping. Note that they are not 100% foolproof however, so it is advised to use multiple sets of jacks if possible. In this way, should a car collapse, the jacks will each share the load over a larger area. This should stop accidents from incorrectly placed jacks.
Hydraulic jacks are available from any car retailer today at cheap prices, so there really is no reason for not using them. Some car enthusiasts insist that using a hydraulic jack is tricky and they take too long to set up. So they take shortcuts, like attempting to balance the full load of one vehicle on a single jack - Not a good idea. These people should see the injuries that some people sustain when they are crushed by a collapsing vehicle - it's not pretty!
One tool that can help those pushed for time is a hydraulic jack, which is becoming more and more utilized in garages today. A hydraulic Jack prevents a vehicle from falling should the lift post or power cut out, and it also offers a very quick and easy way to jack up a car.
However, the use of multiple jacks is just as effective, so there is no need for everyone to run out and buy one just yet.
