  When not in use, a long frame jack should be stored in a clean, dry place away from extreme temperatures and moisture. The jack should be kept away from chemicals and other substances that may damage its components. Proper storage helps protect the jack from damage and ensures its readiness for future use.

How to Choose Long Frame Jack

Choosing the right long-frame jack for a specific business requires an understanding of various factors. Here are some of them:

• Load Capacity

  Safety and efficiency are ensured when a long-frame jack with adequate load capacity to support the weight of vehicles that will be lifted is selected. Selecting a jack with a higher load capacity than required is unnecessary and may result in a heavier tool that is more challenging to maneuver.

• Lifting Height

  Consider the mini long frame jack's lifting height, which is essential when raising vehicles for repair or maintenance. A jack with a higher lifting height is more versatile and suitable for bigger cars, while one with a lower lifting height is more stable and easier to use for smaller vehicles.

• Lowering Height

  Long frame jacks have a lower height that allows them to fit under vehicles with low clearance. This is especially important for sports cars and luxury vehicles. When choosing a long-frame jack, consider its lowering height to ensure it can be used with all vehicles in the fleet.

• Lift Range

  The lift range of a long-frame jack is the difference between its minimum and maximum lifting heights. A long-frame jack with a wider lift range can handle a broader range of vehicle sizes and weights. This is especially useful for businesses that work with various vehicles.

• Construction Material

  Long-frame jacks are typically made from steel or aluminum. Jacks made from steel are more robust and durable, making them ideal for heavy-duty use. Those made from aluminum are lighter and corrosion-resistant, which makes them suitable for portable applications.
