My vintage Blackhawk floor jack addiction continues:
Just acquired this hefty baby. It doesn't have an I.D. tag, but I believe it's an S-4, 4 ton unit. One of it's unique features is a built in head light to assist with jack saddle positioning.
You can actually feel resonating vibrations through the garage floor as this jack is being pushed around, just incredible.
The headlight feature.
The light assembly on this jack has the lens which always seems to be missing on other S-4 jacks that I've seen pictures of. This particular lens has been painted red, but should be clear.
The left hand side of the T-handle is threaded for mounting of the light switch which happens to be missing from this jack.
The underside of the jack.
