to reinforce it weld flat bar across the web at high stress areas (where the ram mounts the push plate starts and around the knife )

as regards the twisting if a ram of that size bottoms out then 35t of force has to go some where, generally the beam flexes till it bends once it bends the forces either side of the knife which are never equal will cause the knife to exert force 90 degrees to the beam and cause twist and buckling

only pics on computer are these will take some better ones tommorrow

Nice one thanks for that, some great ideas in those pictures.

 

Love what i think must be the adjustable blade height on the dumper?

 

In the second picture, what thickness metal is the sliding knife made from? its hard to get scale...

 

Cheers for taking the time to reply and for posting the pictures its grately appreciated.

i ended up taking the adustable knife off as i bent it (15mm plate that ram goes to about 8t)

the slide plate and top of the beam are 25mm plate the foot plate is 60mm thick(two pieces of 30mm welded together)

took some upto date pics today

School boy error today...

 

Having measured the RAM body we thought it had a throw of 10 possibly 11 inch, so as everthing was semi secure i thought id best check. The ram at maximum extension has a through of a whopping 6inch.. c0ck

 

So we took a walk around my mates yard, a burnt out CAT 7ton digger has now donated its RAM to the project and tomorrow i will be cutting the rear off the splitter and making a new rear mount.

 

This ram has a throw of 16inch so all in all i think it will work out for the best in the end!

your 4 or 6 way splitting head looks to be wrong to me, the outside edges need to grip the log first! if it catches near the upright blade first itll spread the wood rather than split it, if im wrong my humble apologies! heres mine, its getting a few more attachments when i am not busy! it self loads too

7 ton ram ? wont be splitting hard wood you need big power for multi splitting

7ton digger

 

The ram is maybe 30t, not sure tbh, it looks more than double the size of my 10t splitter.

 

Going to pipe it and test the blade and power tomorrow. So I'll know if a blade rethink is in order.

There is a lot of talk of rams in tonnage on here and it,s all wrong, firstly they should be measured in force and secondly the force (tonnage if you must) is a function of the ram area and pressure.

 

The less pressure the less force and not all pumps are equal, some are born less able and some are feeble with age, pressure relief valves can also have an effect.

 

The formula is the area of the piston multiplied by the input pressure to give force. Use cm square and bar to give force in kg.
