  1. 1. Existing Products There is a wealth of products on the market to aid mechanics working underneath a car. Each designed to deal with a specific situation. The following is a list of products that are most commonly used along with a description of their function. Access to the underneath of the car Car lifts Car lifts allow a mechanic access to the underneath side of the car in it entirety. The car is supported by its four jacking points and lifted to a desired level. They are by far the safest way to work underneath a car as they provide the most stable support for a car while also being designed to support over the desired weight. Car Jacks Standard car jacks such as scissors jacks and trolley jacks can be used to gain access to the underneath side of a car but are mainly suited for lifting the car to a substantial height for working on brakes or changing tires. If a standard jack was to be used to access to underneath of a car, a car creeper would need to be used. This means of working underneath the car has many disadvantages including, a restricted

Car creepers Car creepers are used to gain access to the underneath of the car when the car is only raised a short distance off the ground. The advantage of a creeper is that one doesn’t need to own a car lift to work on the underneath of a car. This means they are ideal for use in small garages or home used. They have some disadvantages however. For example, they only allow a limited working area. They also cause straining of the neck due to the position of the mechanic. Many older mechanics dislike creeper due to the fact than they require one to lower one’s self onto the device prior to work and then pick them self up post work.
  3. 3. Car Pits Before car lifts became popular garage pits were more common. They allowed total access to the underneath of the car along with the freedom of movement for the mechanic. In recent years however the pit has become less popular as it poses many dangers. The risk of falling into the pit is an obvious one but a danger that most people fail to think about is that of a fire hazard. If a fuel leak occurs the flammable vapour emitted is heavier than air and consequently sinks into the pit and lodges there, a simple spark when welding could cause the vapour to ignite. For these reasons pits are rarely seem in modern garages.
  4. 4. Safety Devices Axel Stands Axel stands are used to support the weight of the car when positioned a short distance from the ground. They are used in conjunction with a regular car jack to provide an element of safety when the mechanic is positioned underneath the car on a creeper. Ramps Ramps can also be used to achieve access to the underneath of a car without the need for a jack. Once again they are used in conjunction with a creeper. The car is simply driven onto the ramps and the hand brake applied.
  5. 5. Stop Blocks Stop blocks are used as a safety device to ensure that a car doesn’t role while being lifted and while in the air. They can be a separate part or can be built into certain lifts. Lifting equipment while underneath the car Transmission jack (high level) These jacks can be used to support various components of the car when they are being removed. They are used with the car is raised above head height on a car lift. Although they support weigh the parts must still be manually pulled out of place by the mechanic.
  6. 6. Transmission Jack (low level) These jack are used when the car is raised a short distance of the ground. Once again the object being removed is supported but has to be manually pulled from its position.
