A high-quality jack does not require any overall modification, otherwise it will have the opposite effect. The handle of the jack is a typical representative of the strict prohibition of modification, because in practical use, people often modify the handle of the jack to achieve higher results, but the result is contrary to expectations. So why can't we modify the handle of the jack?

Safety risk: When using a jack, it is necessary to follow the manufacturer's instructions and safety guidelines. Using other tools to increase strength or make modifications may result in tool failure or sudden release, posing significant safety risks and potentially causing personal injury or property damage.

Design and Engineering Standards: The design and manufacturing of jacks are carried out in accordance with specific engineering standards and safety requirements to ensure their safety and reliability under normal operating conditions. Modifying or adding external components may compromise these design standards, rendering them no longer safe and reliable.

To ensure safety and reliability, the jack should always be used correctly according to the manufacturer's instructions and safety guidelines, and do not attempt to use other tools to increase its strength or make modifications. If you need a larger lifting capacity, you should purchase a jack with a larger capacity instead of trying to modify an existing jack.
