Two-column lift, hydraulic or screw?

Two-column lift, hydraulic or screw?

Two-column lift, hydraulic or screw? Two-column lift is one of the most frequently used equipment of this type in car workshops. It allows for a relatively large range of applications. One of the most important issues when choosing the right device is the preferred drive. Often the first choice among mechanics are screw elevators, also called electric or electromechanical. However, hydraulic drive gains more and more popularity. Which option is better to choose when arranging your own workshop?

Screw drive – solid construction

The greatest advantage of this type of lift is the simplicity of the structure. Thanks to the uncomplicated construction, parts are rarely damaged, and even in the event of some problems, it is easy to find spare parts and make repairs yourself. However, screw elevators are relatively loud and expensive to operate – the energy is used to power the device throughout its operation.

Hydraulic drive – reliability and convenience of work

Hydraulic lifts also do not have a very complicated construction. The whole mechanism works thanks to oil-powered pumps. Such equipment is quieter and does not consume energy when leaving the vehicle – it simply uses the weight of the vehicle. It is also more stable and works faster than screw models. Lifts with hydraulic drive are also considered more reliable.
When choosing a lift for your workshop, it is worth consulting the experienced mechanics. Despite their habit of electromechanical drive, many of them emphasize the superiority of hydraulic lifts, which are less emergency and are better suited for various applications.

Choosing a lift is a real challenge for the workshop. It is worth equipping the workshop with a jack so that you do not run from and to the channel and that the repairs take place in more comfortable conditions. Depending on what is most needed, we can meet the three main types of lifts. I am talking here about a two-column, hydraulic and screw lift. Each of them has its own advantages and disadvantages, which are worth knowing before we decide to buy.
Versatility, durability or strength

Two-column lifts are very popular, which owe their universality and relatively low price. The whole works on the principle of sliding carts on guides, on which the arms are embedded, which are additionally adjustable in the range of extension length. As a result, vehicles with differently spaced support points can be raised. The price of this solution depends on the type of drive and the possible permissible load capacity. The disadvantage is the lack of access to certain places of the car, e.g. a gearbox. There are also works that we will not be able to do with such lifts (eg wheel geometry).

In this case, we have hydraulic lifts, which are additionally characterized by extremely quiet and fast work and reliability. A big advantage is also a very strong support, thanks to which the lifted car is stable.

However, if we are looking for something that will be able to lift or move large masses, nothing will work better than a screw jack. It operates on the basis of a motor and worm gear. These elevators are also a great choice when you want to pick up speed and the ease of synchronizing drives.
A lift for a small workshop

The task of lifts is to move away from the channel system and to facilitate work. The three types described have their own variations, which may be useful in specific applications. So when looking for a lift for our workshop, it is also good to suggest opinions of other customers, workshops that use a given type of lift.

Two-column lift, hydraulic or screw?

The lift is an important element of the car workshop. Without it, it’s hard to imagine most of the work, so the decision to buy it can not be accidental. It is necessary to think about it, check the offers and choose a device that will fulfill its task over the years.

Before buying – what is important?

The most important thing to think about before you buy a lift is its future destiny. It seems to be a trivial matter, but expectations may be different in each plant. It is important to answer the questions, how much work intensity the lift will have to withstand, what is the range of services proposed by the plant, what premises conditions are available. It is also important to consider which vehicles are most often operated, as work related to passenger cars requires a different lift than works related to several-tonne vehicles.

Two-column lifts are one of the options available in this type of equipment. It is a good option if you need a position for various types of work, without the need to create more for various orders. Among the noteworthy features, the most important thing is the ability to adjust the height of the hoist to the work currently being performed, as well as to increase the employee, which adds to the comfort of work. Thanks to the two pairs of arms, the two-column lift raises the vehicle to the desired height, allowing repair work on the chassis.

Hydraulic jack

Another lift that you can choose is a hydraulic lift. It makes it easier to lift heavy objects when liquid is used, which pushes out one of the parts of the lift causing it to rise. This makes it easier to work on heavy parts that require lifting a part of the vehicle or machine. It can help, but it is less practical compared to a two-column lift.

Screw jack

There are also screw elevators available on the market, which can be used mainly for work with the stage and in the theater. Facilitate the lifting of scenes or rows of seats in the theater by linearly moving the elements and acting like lifting, lowering and pressing devices.
