Fork and Grapples | Albutt attachments materials handling

 

These people took over from my previous supplier, they're to Peter's hawkfork design and I did buy one for the JCB telehandler and it seems fine, it's a pig to connect up the hydraulics even with quick connectors if there is a temperature change from when last used.

Can you not release the pressure in the fittings before plugging in? I've got a hex head combi-spanner for a bit of proddy proddy jammy jammy when the quick releases want a fight.

No I tried that. Only way round I found was to switch JCB off and leave for a few minutes and then bleed a bit of oil out of the grab connector, there was too much pressure to push the centre of the quick connector in.

 

I did wonder about jacking the grab up and down but it was easier to lose a bit of oil.

Thanks. We all ready have the albutt log grab and that works brilliantly.

We keep a bolt welded to a flat plate in some machines put the bolt inside the quick coupler wrap in a rag and smack against the headstock will release pressure

Also sometimes helps if you leave grab parcially open turn off machine and depresurise same as usual as sometimes if presurised to hard in pne direction it wont depresurise think its how a check valve is fitted in the system

Another option is screw on quick couplers

 

Oh and allbut do proper brush and grubbing out grabs but are around 5 grand

My fendt is a pain plugging 3rd service in when grab been stood for a will, way I do it is stop tractor push button on joy stick and move it about to release all pressure and plumbs in no problem.

Yes that de pressurises the tractor hydraulics ( but JCB controls don't do this as they are electro hydraulic controls so engine has to be off and time allowed for oil to drain) but the oil is locked in both sides of the grab ram so if someone has disconnected it with the engine running or if the oil trapped has pressurised by change in temperature it has to be bled off a tiny bit.

The drip free couplings are worse at this, in the good old days screw on Dwoty couplings over came a certain amount of pressure.
