Have you ever been to the service station? Cars are usually loaded onto gradually rising platforms. The platform uses the same tool called a hydraulic jack. This device or mechanical instrument is used to lift the weight manually, requiring manual effort. The most common are mechanical jacks. However, other people rarely use the floor jacks and bottle jacks that are often used. They all use the same basic phenomena, but their shapes are different.
Hydraulic Bottle Jack use a fluid that is incompressible and is constrained in the cylinder by a pump piston. When the plunger is retracted, oil is used, which leads the oil out of the source through a suction valve in the pump chamber. When the piston moves forward, it drives the oil through the discharge check valve into the piston chamber. Hydraulic jacks are a very important tool in the construction industry and in the workshop because it reduces the large amount of work of the machine and the laborer, and has a wide range of applications in these fields.
In a hydraulic bottle jack, the piston is upright and directly holds a bearing pad that supports the suspended object. When using a single-acting piston, the elevation is slightly less than twice the fold height of the jack, so it is only suitable for cars with high clearance. For a lifting structure like a house, the hydraulic interconnection of multiple vertical jacks through the valve makes it possible to distribute the force horizontally, while restricting the tight control of lift.
The hydraulic bottle jack must be larger than an ordinary car jack, and even require you to bring wood or metal plates when you use it. Flat plates are necessary to ensure the stability of these hydraulic jack mounts. However, if you have a large vehicle and there is extra space behind it, you won't regret to have a hydraulic jack instead of a manual jack. Most four-wheel drives have luggage compartments that can carry two people's luggage, so hydraulic jacks and their bases should not take up too much space.
