A good friend arrived to move a container for me this morning ,she is an eighty ton krrupp,and he has owned her for four years .Mick retired home in '99 after a career globe hopping driving everything from a 5 tonner to tower cranes in Honk kong .He worked for Van summeran (??)and has worked on each of the five continents,A down right gentleman with many a sceal to stand the hairs on a mans neck,or give him a pain in the side from laughing.

Those Krupp crane's look tough.I think the all-terrain grove crane's are of krupp design.They get around good in off road and tight quarters,with the all wheel stering.

you would be right ..Grove bought out Krupp's crane division back in the early 90's

They halve an interesting boom design on the newer models.The way I understand ,Each boom section get's pinned after it's extended.When the boom is at the desired length The extintion cylinder is retracted to the bottom section ,thus reducing boom weight.Is this true?

Krupp kinda started doing it first ..as time went on it got better

Yes ..in alot of the newer hydraulic cranes ..the Cylinder locks into a section and pushes it ou ..then its pinned ..the cylinder lets go then retracts to get the next section ..

now that said heres your computer options built into the menu..

Manual where you do all the pinning and unpinning and scoping of the cylinder via a computer interface,

Semi-automatic ..where you move the cylinder and the machines pins it up and you retract the cylinder ..theres a few more details ..nothing major.

Full automatic ..you plug in the code for the desired boom lenght or chart and she goes there ... just hold the throttle and lever over and watch the screen ..she'll do her thing and park when she's done ..

theres a pile more stuff to make you feel at home ...This can quickly become another thread

Spoke to Mick this morning ,who was real chuffed at the interest shown by you all .He asks if anyone would have access to a maintenance manual for the above crane which he said is a 4070(modified to a 4080) 8109 built between Sept 94 and Jan 1995.He has the books for her but alas they are all in german, a language neither he or I have no command of , so any help would be appreciated

AHHHHH ....your 8 mths to late .. i could have copied one ...the machine was sold.
i think the difference between the 4070 and the 4080 was a couple inserts of counter weight placed in the counter weight slabs that mount to the upper .. and a pair of kidney stones that sit on top of the top slab ..other than that they are pretty much the same ..

but ..there is a place in Texas that scraps and recyles crane's ,,and refurbishes parts to be sold ..including that Krupp ..just dont know the name of it..


But in the mean time take very good care of the mega-track .. the bands that the cylinder's rotate on ..you cant buy bearings for them any more just the whole assembly ,,very pricey ..and the two crows legs that pivot up and down with the same cylinder's ..keep a oil can with transmission fluid handy they are getting very expensive as well ..keep them lubed ..

Get ahold of Mercedes and get a hand full of fuel injector O-rings ..we had a bunch go out ,it will ruin the head if its not looked after quickly.

the 24v webasto heater in the upper will run forever if you keep Kerosene in it ..but when it cack's put an Espar in much cheaper to maintain ..should it have a hunter right now ..you cant buy parts ..

If theres anything in particular you wanna know i may be able to help ..untill you get the book's ..

Its funny really ...the place i worked ..they hired a German Mechanic ...
