How to choose?
To choose a jack, you must first decide on its carrying capacity. If you have a car, then it can be a model up to 3 tons, if it is a truck, van or SUV, then the carrying capacity should be more than 3 tons. This indicator in any model of the jack should always be with a margin.
The pickup height is important, as this figure determines the distance that the jack can lift the machine. Lift height is also a very important indicator when repairing a car, it determines the very point of lifting of the vehicle
The most reliable and convenient, providing maximum lifting of the load, are hydraulic bottle jacks. They are great for all kinds of machines. The only drawbacks they have is a small fulcrum and the need to store and use only in a perpendicular position.

Among the jacks collections there are rolling, hydraulic, rack and pinion jacks and bottle jacks.
Rolling jacks are considered to be the most suitable for workshop work. The design of such a device consists of a long removable handle, which not only well reduces the physical costs of lifting the load, but also facilitates full-length work.
Hydraulic devices are based on fluid properties. The principle of operation is that the drive pump builds up oil pressure and thereby moves the piston. This is how the load is lifted. The liquid moves into the container of the pump and the load moves downward. Such devices can lift heavy loads with a minimum of physical effort. They have smooth operation and high efficiency.
Rack jacks are the most common in construction, installation and dismantling activities. It is characteristic for them that the end of the rail is bent at a right angle. With such a device, it is very easy to lift the load from the lowest level, because the rack jack has a lifting platform with a low position.
Bottle jacks are considered to be the most practical devices. They are capable of tasks of varying complexity thanks to a well-thought-out design. Their working mechanism is based on the properties of the liquid. These options have a large piston chamber - the main reservoir, which is completely filled with oil, and a small piston chamber that creates pressure in the hydraulic system. There is also a lever, discharge and test valves.
