Chain forks can be used in many ways. As shown below the chain fork lifts a completely
wrecked truck -no axles or tires -and the under reach functions as a tow bar.
The chain forks are milled from one high tensile steel bar and accept 1/2" to 5/8" chain.
The other picture shows a dump truck lifted from the rear where no easily accessible lift point was available.
