Use the right vehicle information
Vehicle weight, engine displacement and attachment geometry answer different questions. Start with the relevant specification from the vehicle or equipment documentation before selecting a tool.
- Check rated capacity at the actual configuration, including an engine hoist's selected boom position.
- A lifting jack and support stands serve different purposes; do not treat them as interchangeable.
- A preliminary sizing result does not replace manufacturer instructions or a safe working procedure.
