The question of what exactly a car lift is called often arises among novice car enthusiasts and garage owners planning to set up a full-fledged workshop. In everyday life you can hear many names: from a simple “jack” to complex technical terms like “hydraulic lift” or “overpass”. However, the correct name depends on the design of the device, its load capacity and installation method.
Understanding the differences between these mechanisms is critical not only to purchasing the right equipment, but also to ensuring safety while performing the job. Using the wrong type of support can result in the vehicle falling, causing serious injury and property damage. In this article we will analyze all the main types of devices for lifting equipment, their design features and areas of application.
It is worth noting that professional slang can be confusing. What is called a “lift” in one service is called a “column” or “scissors” in another. We systematize this knowledge so that you can accurately formulate your request when purchasing or searching for information.
Basic classification of lifting devices
All devices for lifting a car can be divided into two large groups: mobile and stationary. The first category includes tools that are easy to move around the garage or carry in the trunk. Mobile liftsjacks, such as jacks, are intended primarily for changing wheels or express repairs.
The second group consists of stationary structures that require installation and, often, communications. Stationary lifts provide maximum stability and allow complex work to be carried out under the car for a long time. The choice between these categories depends on frequency of use and available space.
The classification is also based on the principle of operation of the mechanism. There are hydraulic, electrical, pneumatic and mechanical (screw) systems. Each of them has its own advantages in lifting speed, reliability and maintenance costs.
Jacks: mobile solutions for the garage
The most common answer to the question “what is a lift for a car called?” is the word “jack”. This is a compact device that lifts the car to a small height, resting on one point of the body. There are various modifications, each of which is suitable for different tasks.
Most Popular hydraulic jacks, which are divided into bottle and roll-on. Bottle ones are compact and have a high load capacity, but have a limited lifting height of the rod. Trolley jacks, often called "frogs," provide a smoother, higher lift, which is useful for low-clearance work.
When choosing a rolling jack, pay attention to the material of the wheels: polyurethane ones do not scratch the floor, but rubber ones dampen vibration better and slide less on oil.
Mechanical (screw) jacks, which often come with your car, are reliable, but require significant physical effort to lift a heavy SUV. Pneumatic models are used mainly in professional services where there is a compressor line.
⚠️ Attention: Never crawl under a car that has only been lifted by a jack! This device is intended solely for lifting and not for long-term holding of loads. Be sure to use safety stands when working under the machine.
Stationary lifts: types and designs
If you are thinking about a full-fledged garage service, you need to understand the types of stationary lifts. It is they who are most often called “elevators” or “lifts” in a professional environment. The design is selected based on the type of work and the area of the room.
Two-post lifts are the “gold standard” for auto repair shops. They take up minimal space and provide excellent access to the wheels and underbody. However, their installation requires a solid concrete base with a thickness of at least 15-20 cm. Four-post models are more stable and are often used for wheel alignment or vehicle storage (parking elevators).
Scissor lifts can be built into the floor or mobile. They do not require racks on the sides, which is convenient for washing or body work where access around the entire perimeter is needed. Plunger (hydraulic) lifts hide underground and extend upward, freeing up garage space when not in use.
Technical requirements for the floor
To install a two-post lift, concrete of a grade not lower than M250 (class B20) with reinforcement is required. The thickness of the slab must be at least 200 mm. If the floor is thinner, reinforcement or the choice of a mobile version of the lift will be required.
Overpasses and inspection pits
In garage cooperatives and private households, structures that are not formally lifts, but perform the same function - provide access to the bottom of the car are still popular. Inspection hole - This is a recess in the garage floor that allows the mechanic to be under the car.
An overpass is an elevation onto which a car drives. It can be a complex metal structure or a simple concrete structure. The main advantage of such solutions is the absence of moving mechanisms that can break, and the ability to simultaneously service several areas of the vehicle.
However, these methods have significant drawbacks. To dig a hole, you need to know the groundwater level, otherwise the garage will be flooded. The overpass requires a large space for entry and occupies a significant area. In addition, the lifting height in the pit is limited by a person’s height, which is not always convenient.
- 🚗 The inspection hole requires high-quality waterproofing and ventilation.
- 🏗️ The overpass must have reliable wheel limiters (stoppers).
- 📏 The width of the pit is usually 70-90 cm, which is optimal for most passenger cars.
- 🔦 Lighting in the pit should be safe (low voltage) and bright.
Comparison table of characteristics
To finally decide on the terminology and choice, it is convenient to compare the main parameters of various devices. The table will help you understand what exactly is suitable for your conditions.
| Device type | Load capacity | Mobility | Difficulty of installation |
|---|---|---|---|
| Jack | up to 3-5 tons | High | Not required |
| Two post lift | up to 4-5 tons | Low | High (foundation) |
| Four post lift | up to 5-6 tons | Low | Medium (anchoring) |
| Scissor lift | up to 3-4 tons | Average | Medium/High |
| Overpass | Unlimited | Missing | High (construction) |
For a private garage, the optimal compromise is often a combination of “high-quality rolling jack + safety racks,” since this does not require destruction of the floor and high costs.
Safety and technical nuances
No matter what your chosen vehicle lift is called, safety should be your number one priority. Hydraulic systems are prone to “sagging” over time, so leaving a car on them overnight or for a long period of time without additional fixation is dangerous.
When using two-post lifts, symmetrical installation of the lifts is critical. If the center of gravity shifts, the vehicle may fall off. The instructions for each car contain special lift points, which are structurally reinforced.
☑️ Safety check before lifting
Regular maintenance of equipment extends its life. Hydraulic oil need to be changed according to the regulations, and the hinge joints need to be lubricated. Electrical components must be protected from moisture and dust, especially in a garage environment where cars are frequently washed.
⚠️ Attention: It is prohibited to lift a vehicle if its weight exceeds the maximum lifting capacity of the lift. Also, you cannot lift the car by plastic body parts or suspension parts that are not intended for this purpose.
Frequently asked questions (FAQ)
What is the difference between a jack and a lift?
A jack is a mobile device for short-term lifting (for example, to change a wheel). A lift is a stationary or semi-permanent structure designed to safely hold a vehicle suspended for a long time for repair work.
Which lift is best for a small garage?
For limited space, two post lifts with narrow columns or mobile scissor lifts are best. It is also worth considering the option of a plunger lift, which is hidden in the floor, leaving space free.
Is it possible to install a lift on the second floor?
Theoretically it is possible, but this requires complex engineering calculations of the building’s load-bearing structures. Most often, only light mobile devices are installed on the second floors, since the weight of a stationary lift with a car can reach 3-4 tons.
How often should a lift be inspected?
At home, a visual inspection is carried out before each use. It is recommended to carry out a full check of the condition of cables, hydraulics and electrics at least once a year, and in commercial services - monthly according to Rostechnadzor regulations.
