Chances are good this was a "Steinbock" too! They used chains in the 30's and 40's right into the 50's and possibly 60's. In different sizes and forms, for use with cars to trucks or coaches. Back then they were leading in lifting technology.
A mechanical pre-war trolley is on my wish-list The big advantage is, that they don't have hydraulics and thus are very simple to maintain and "failsafe". It's harder work, though. If you look at the Crab - that's a design from the 1930's And demands a bit of muscle power to lift heavy stuff.
Yes! That's just the one! It has a ridiculously long body for a relatively small lift. I remember the direction switching by means of the "Fusshebel" (foot lever).
Steinbock are still on the go, the office I work in has a pallet transporter, rather newer than your trolley jacks. Someone stole the K from one STEINBOCK to make KEINBOCK (= can't be arsed) on the thing.

The lift might not be very impressive; but then - back then live axles were a widely used standard. And you just don't need as much lift to get a wheel off the ground with a live axle But the long body helps you to get there without crawling under the car... Nowadays they'r a bit useless, that's true
On thursday I started yet another safari. Starting with a very good fuel price:
Onto the Autobahn, and then my route got more interesting when I entered the Westerwald area and the roads got smaler and smaler and very twisted.
And when I thought I had reached the end of the civilised world, there appeared a ridiciously smal village, not more than 10-15 houses. I loaded my newest accuisition (we almost couldn't lift the damn thing in the boot!!).
I took the scenic route home, via a short stop at a friend I've not see in a while - was nice to meet up, drink a coffee and sit in a Mini again - after years.
And that's the new chunk of iron:
a Type "HGA", the hydraulic version of the Crab. And since it's tail-heavy, it's even worse to maneuvre this thing I had to have it, since it's very rare and easyer to operate than the mechanical Crab. And it has a bit more lift and hold 1200kg!
It works, it's greased (owned by a old chap who took good care!) - apart from a lick of linseed oil there's nothing to do. Though perhaps I need to straithen one of the arms that holds the rear castor wheels, it's bent (how!?). Read; cut, adjust, weld. There'S no way I can bend this back... And with this the fleet of operational Capricorns looks like this:

I recently had a increase in storage space - so that's bound to be occupied, right? I don't have the space to collect cars though. So I'm collecting smaler stuff with wheels. And with these I can always sanctify collecting. And "wasting" space - 'cause they'r usefull. Right?
Gave the Hydro-Crab a lick of oil - which revealed a lovely patina - it blends right in the collection

First examination of the Hydro-Crab revealed one badly rusted castor wheel. On brighter note, the patina is totaly awesome!!
The shaft is very pitted, as are the rollers. I've polished the shaft as good as possible. The rear castor wheels are the biggest I've come accros yet, and the shaft is double-welded which probably makes it nigh on impossible to replace. Or at least very difficult. I'll see if I can get away with good molycote grease - if not, I need a man with a lathe.
At least the other side is in very good condition, given it's age. For the damaged side I've ordered some 3mm steel to cut new rollers. I've tried to get hold of 3mm round bar - no chance. And nails are either 2.8 or 3.1mm *D'oh!*
The initial plan for today was to cut, adjust & reweld the bent castor wheel arm - but 35-37° in the shaddows stopped playing and I rather settled for a cool Weizenbier... Sans acohol, since I didn't want to drop dead

Actually I think it could replace the whole fleet. But then - it's a heavy, hardly maneuverable steel beast... I've ordered some round bar and some tube yesterday, to remanufacture the original pump handle and the roller needles. The pump handle that's on right now is a home-bre affair and doesn't work under a car - it's too high. More on that once I get to it.
And before it gets too hot, I've cut, adjusted and re-welded the castor wheel arm. Brushed it with a dirty brush I use to clean engine parts. and put on some Owatrol oil. Looks like just an old repair I decided for a visible repair - it's got a battle scar now

"little thing" - lol!
Very interessting: this has got brass bushes (resp. one is left) instead of needle rollers on the front castor wheels! I don't know if they are factory, but it looks that way as there are no signs or marks of rollers. I've ordered some fitting brass tube to replicate this - I think it's a much neater solution than the needle bearings. It's also the first small roller with a grease nipple I've come across... The shaft has a bigger diameter so sadly wont fit the big trolley jack.
The Crab came in very handy to carry away the dismembered Hydro-Crab
More updates as soon as I get delivery of my raw materials

Red Cross Crab
Step 2 at reviving the Hydro-Crab; got delivery of some 3mm wire (you would not believe it, but noone localy had 3mm round bar!). Cut to 56mm long pieces, ground the adges - et voilá - a set of 33 new needle rollers for the rear castor wheel
I also got a piece of 25mm steel tube - with this and the old (homebrew) pump lever I made the new pump lever. Similar to the original of which I only have a rough drawing...
I got the angle right, and you can pump with the lever swayed as far forward as possible. Right above the castor wheel. Which makes for much better under-car operation.
Remember, this thing is actually a transmission jack! It dates back (like all of these jacks do) to a time where not every garage had a lift and mechanics would frequently work cramped under a car on axle stands. This thing, like the Mecha-Crab, was desgned to allow one-man gearbox removal & installation. So it's quite important to have a horizontal, rotating pump lever.
Which the Hydro-Crab got back now. Still awaiting delivery of some brass bearing sleeves for the front castor wheels and a steell ball to finish off the pump lever.
The needle bearings work well - the castor whel does a full 360° spin with a little push I'm positive it will work OK-ish, despite the rust scars. After all it's not a fast spinning wheel baring or something like that. In fact, I guess, it will see very little action

Today I finished the HGA aka. Hydro-Crab. I had ordered some brass bushes - unfortunately they didn't have the size the seller said they have. The were some 1/10mm too smal. Some carefull work with the flappy-wheel in the drill sorted that out, though. Then added some grease channels, a hole - and done. Repeat 2x.
They work just as well as needle rollers - so I may stay with this method as it has some advantages. Easyer to manufacture and offers better support. And brass is a good bearing material.
The handle will still need some more rusting & a special treatment - but for now, the Hydro-Crab is finished And makes an even better stool, being hydraulic
loving your old jacks, and it seems like you have an addiction now..lol
i was looking recently to buy a new trolley jack myself, getting one that's not made in China now is very difficult, anyway set my sights on a Compac 2T one, saw a secondhand one pop up on ebay, bid and won, only drove a 140 mile round trip though, not as old as your's but i'm hoping its going to outlive me
