Pivot steer loader diff lock

[Ruston3w]

Thinking of replacing old Volvo shovel and Merlo loader with something like 320 jcb, Manitou 533 or similar, some have limited slip diff, some self- locking and Wiedermann ( possibly JCB?) have proper diff lock, how do people get on with either? I have had a Kramer 55kl on demo, a little sticky stuff and a 2t fork full of poplar had 1 front wheel spinning, no better than Volvo.

Weidemann 5080t here. Has a positive locking diff lock, activated by a button on the back of the joystick. Works as it should and doesn’t scrub tyres like a limited slip diff, but not so sure it’s an issue on pivots compared to 4ws, 2500 hours was the limit on a set with a 4ws Manitou.

320jcb has lsd front n rear

Limited slip and self locking diff is the same thing just different wording.

Both manitou and jcb pivots have it front and rear I think.

The way limited slip works is the more load you put on the wheels the more force will be applied to the diff gears forcing them apart that compresses the limited slip diff plates to partly lock it up. There are 3 x % levels of locking available on a Dana spicer axle I think. 25% , 35% and 45% I think

Not sure which manitou use tbh but might tell you in the specs in handbook or sales BS.

OK, maybe the Kramer is working on a figure at the lower end of that. I have a 533 Manitou here also , may try it and see how it behaves.
I don't know how much the Weidemann boys miss limited slip in " normal" use? I can't believe they're flicking diff- lock in every time they push into a heap?

if a slipping wheel isnt under any load then there will be no force on the gears to lock up the diff plates so dont have one wheel cocked up in the air and expect the limited slip diff to work cause it wont or not very well anyway.

533 walked past it, just been down and tried, bought 3 poplar trunks back on second load rather than 2 ,guessing 2.5t
Something to do with pivot rather than 4ws? No idea why there should be so much difference. We have always got some woodland/ marsh maintenance work lined up so don't wish to make wrong choice! Shame the crowd function on Manitou has a hair trigger, you have to be super careful loading potato crates for planter. It would be perfect if there was a pallet handling/bulk handling rockswitch.

Doesn’t it have flow control?

It's 3.3t lift so alot bigger machine than kramer.
There will be multiple hydraulic settings on it I think but I not driven one. You should read manual as you will not get best out of machine and its functions if you dont.

Thanks for your help. The Kramer is 2t heavier, 1t more lift but less traction it seems.
I only posted here as have read book and by Monday when I can ask TNS I won't have time to try it any more. There is means to adjust both auxiliary services, as well as transmission settings but I can't find anything about crowd function. Probably me being slow, hence asked.

LSD in our JCB 538/60 is hopeless the positive diff lock Merlo was excellent along with portal axles. Would I go back to a Merlo. No way JCB better IMHO in so many ways despite it's faults. As an owner driver putting 1000hrs a year on it my back finds it so much better to hop in and out and to sit in rather than on!

The centre boom Kramers had a locking diff activated by a button on the joystick.
On the newer ones you had to press the brake pedal to make it activate.

5080 weideman here only time we really use the diff lock button is pushing up grass at silage time to be honest, or if filling stones into a stone cart for drains maybe but that’s about it

Yeah i googled the kramer model number after, didnt realise it was the big one so not sure why but my guess is then manitou being pivot steer maybe has a higher % limited slip diff compaired to the kramer 4ws even though they both run dana axles.

 

[Ruston3w]

Thanks all, on the diff lock front kramer has no lsd but locks with button on back of joystick with brakes on, correct TrippleSix, it disengage when you let go of button , or as soon after as under no load. More get out of gaol than working in mud.

Try the appropriate size Weidemann or Shaeffer if you want a big pivot loader?
