What Are The Different Types Of Jack?
Whenever you have to raise up your car and for whatever reasons, you have to simply get the right equipment for that.
For this reason, there are different types of jacks such as the basic scissor-type found in many vehicles to the heavy-duty models for use with big trucks.
A jack is simply a device used to raise vehicles either partially or wholly for either maintenance or repairs. Basically, there are two main types of jacks: (a)Mechanical jack and (b) Hydraulic jacks.
Mechanical jacks also come in different types which include: the scissors jack and the high lift jacks. The scissors jack is a lightweight jack found in most cars. (Read Also: Can Tire Pressure Sensors Be Disabled?Find Out Now)
It is compact, portable, reliable and should therefore be carried in all regular vehicles. Scissors jacks are usually provided alongside a spare tire. They require little maintenance since they do not use any fluid for their operation, which means that they don’t leak.

They can also be used either vertically or horizontally. These jacks are used for winching, spreading metal for those trapped in accident vehicles, and pulling or clamping heavy loads.
These jacks operate on the principle that pressure, when applied in a fluid, spreads evenly throughout the fluid. In these jacks, the pressure is created through a pump plunger which moves hydraulic oil through cylinders.
The types of hydraulic jacks in use include (a)Bottle jacks and (b) floor jacks. The bottle jacks are mounted vertically and force weight in an upward direction. They are portable, inexpensive, and easy to use.
On the other hand, the floor jacks are long and horizontal with a low center of gravity which is compatible with vehicles that have low clearance. Another thing worthy of note with these jacks is that they are bulky and hence, difficult to store in small spaces.
They are equally operated in a standing position and are thus suitable for people with back pain and other bending issues.
Tips for using a car jack properly
The first thing to know is that a car jack should only be used to raise a vehicle up and never to keep it in place. Before jacking up any car, park it properly and always use jack stands if you plan to go under the vehicle.
Finally, use jacks only on flat surfaces, but never on a slope,Â if you can help it. If you must park on a slope, turn the wheels towards the curb and put chocks behind the wheels that remain on the ground, which will help to guard against accidental rolling of the vehicle.
Do not also forget to turn on your hazard lights. Never attempt changing tires on the freeway or at the side of a busy highway.
How Do You Jack Up A Car Safely?
The first thing to do is to check the wheels opposite to those you wish to work on by using a wedge-shaped piece of material such as wood, rocks, metals, or other obstacles.
After doing this, locate the jacking points on the underside of the car, which are mostly behind the front wheels but in front of the rear wheels. (Read Also: What Size Tire Can I Put On A 20Ã—10 Wheel?)
Then place the jack beneath any of these points before lifting the car. For a mechanical scissors jack, you need to put the long arm of the jack in place.
A hydraulic jack, on the other hand, requires the user to fasten the arm in place by using long and slow strokes to the top and bottom of the rod. Thereafter, the insert jack stands close to the jack before lowering the vehicle to sit on them.
If you are not going under the car, it is needless to put the jack stands. After completing the work, raise the vehicle slightly so that you can remove the jack stands, before fully lowering the vehicle and sliding out the jack.
What Are The Dangers Of Using Car Jacks?
If car jacks are used incorrectly, they can be very dangerous. It is known that over 160 serious injuries happen each year due to carjack accidents which include amputations, crashes, or fractures. For instance, the car can fall on top of you with devasting consequences.
This kind of accident has resulted in countless deaths worldwide. To avoid car jack accidents, observe the following safety tips: Always park the vehicle on hard and level surfaces and never on a slope or grass, and make sure that before raising the vehicle the free wheels are chocked.
Always make sure that the right jack is used for any vehicle raised since not all jacks are the same judging by their weight capacities and different functions.
Make sure that you read the safety manuals on the jack provided by the manufacturers, and also make sure that you diligently read the car’s workshop manual in order to get the right points to place the jack.
Use jacks at only the recommended positions and if you must go under it, use jack stands or support ramps.
