What is two post -lifts?
Two Post Hoist is a device that can lift heavy loads with a hydraulic or electric motor and two sets of lifting arms. These jacks consist of two tower structures that are usually referred to as posts. Each post contains a cable, a chain, screw drive or a piston that is connected to a set of lifting arms. When the engine is activated, the elevator device is used to pull the lifting arms out of the ground and then increase the load. These jacks are usually used in automotive applications as an alternative to an elevator type of underground cartridges and quads on the platform. These elevators are versatile and come in different configurations to suit different situations. The main types of two postcols are hydraulic and electric, although there is also a popular combination of these two. In the EU are popular purely electric two post -kicollano, where the stroke mechanism often uses a screw unit. Electric hydraulic units use an electric motor to create necessaryUnlike pure hydraulic units that usually use compressed air.
One of the common features that most of the two units after the elevator with electric hydraulic units are equalizing cables. These cables are designed to ensure that the lifting arms on each side raise about the same time by connecting the lifting mechanism in one tower with the corresponding mechanism in the other. It is possible that these cables pass from one post to another on top or below, depending on the design. If the leveling cables and the hydraulic lines pass from the bottom of one column to the other, there is usually a type of shear plate above them to prevent damage.
Two post Hoist can also be symmetrical or asymmetrical, which refers to the location of the shoulders and the way the load on the jack is. Symmetrical twoPostcols have lifting shoulders that have the same length, so any load will tend to be concentrated in relation to the towers. Asymmetrical two post -lifts usually have shorter front arms, which leads to the fact that on one side of the towers there are more loads than on the other side. This may be desirable when lifting certain loads, such as cars that are much heavier in front than at the back. Symmetrical jacks are also useful for lifting vehicles under certain circumstances, such as vehicles with particularly long wheels.
