How to choose a suitable jack according to the actual situation?

I. Lifting weight requirements

First of all, it is necessary to clarify the weight of the heavy object that needs to be lifted. Jacks all have their rated lifting weights. The selected jack should have a lifting weight greater than the actual weight of the heavy object and leave a certain safety margin. For example, if you want to lift a 2-ton car, you should choose a jack with a lifting weight of at least 2.5 tons or 3 tons to ensure that there is sufficient carrying capacity during operation and prevent the jack from being damaged or even dangerous due to overloading.

II. Lifting height requirements

Consider the required lifting height in actual work. Different types of jacks have different lifting strokes. If you need to lift an object to a higher position, you need to choose a jack with a larger lifting height. For example, when changing a car tire, the car body needs to be lifted to a sufficient height to change the tire. At this time, you need to choose a jack with a suitable lifting height according to the distance between the vehicle chassis and the ground and the operating space required for tire replacement.

III. Use environment

Space limitations:

If the working space is relatively narrow, such as when performing maintenance operations under the vehicle, and the space is limited, a jack with a small size and compact structure should be selected. For example, a hydraulic horizontal jack may be more suitable for use in such a space-constrained environment. It can start lifting at a lower height and occupies a small space.

For some places with open space but limited height, a thin jack can be selected. It can provide a large lifting stroke at a lower initial height.

Ground conditions:

If it is used on a hard and flat ground, a more conventional jack can be selected. But if the ground is uneven or relatively soft, such as in the wild or on a construction site, a jack with a larger base area or a special stabilizing device is needed to ensure that the jack will not tilt or sink into the ground during the lifting process. For example, a screw jack or hydraulic jack with a wide base and anti-slip pad can better adapt to this environment.

IV. Operational convenience

Operation mode:

Jacks are divided into manual and electric. Manual jacks are relatively simple to operate and are cheaper in price, but require greater manual operation. If it is only for occasional lifting operations of small items, a manual jack may be an economical choice.

Electric jacks are more convenient and fast to operate, especially suitable for situations where lifting operations are required frequently or heavy objects are lifted. However, electric jacks are more expensive and require a power supply.

Weight and portability:

If you need to carry a jack frequently for mobile operations, such as vehicle rescue, you should choose a jack that is lighter in weight and easy to carry. For example, some small hydraulic jacks or jacks made of aluminum alloy are light in weight and small in size, and can be conveniently stored in the trunk of a vehicle.

V. Reliability and brand

Quality and reliability:

Choosing a well-known brand and a reliable jack is very important. Well-known brands usually have better quality control and after-sales service, which can ensure the safety and reliability of the jack during use. You can evaluate the quality of the jack by checking user reviews of the product, consulting professionals or referring to industry standards.

Check the manufacturing process, material quality and safety certification of the jack. High-quality jacks are usually made of high-strength materials, with a solid structure and have undergone strict quality inspection and certification, such as ISO quality certification.

After-sales service:

Considering the after-sales service of the jack is also an important factor in selection. Good after-sales service can provide timely maintenance or replacement services when there is a problem with the product, protecting the rights and interests of users. Choosing a brand and supplier with a perfect after-sales service system can make users more at ease when using the jack.
