They are even handier when used in pairs. Rig a chain to it and it can replace a winch. You have to work it 3' at a time. Very adaptable and capable tools.

The one thing you don't ever do with them is get under a load they are holding. The design is good and reliable for cargo lifting but entirely unsuitable for protecting a life.

Lots of people have been injured when the ratchet pawl broke, slipped or failed to stay engaged at the wrong time. They are a even worse if not well maintained and kept in near-perfect condition.

Well maintained, expertly and carefully used they are a tremendous asset. Inexpertly or carelessly used your better off calling a tow truck.
