From my experience with the Doosan brand their more trouble then there worth poorly engineered, unreliable and hard to source parts for after a few years of development I cannot recommend them for heavy work loads but for a shop forklift their alright.

Do not want to sound like a broken record Parts, parts ,parts,parts. You can have the biggest piece of junk around , BUT , if you can get the parts you need that will just about offset anything else. Can you say the word BACKORDER!

The engine is a doosan diesel engine, no help there. Luckily we have a local electrical rebuilder that sources hard to find parts for us. The 5k or 6k trucks are pretty easy to work on and seem to be fairly reliable that I have seen. Heard from local dealer the larger units have some computer issues as far as diagnostic equipment is concerned. Again I am not a dealer for them so perhaps someone else can tell a different story.

Jeremie - On the big trucks, I often get the engine make/model/serial number and source starters and other parts like that directly from the engine manufacturer. They're often a little less expensive and more available.

Thanks for the info. We won't be using anything above a 6k. I will make sure to talk to our dealer and get all info for the lifts as they arrive.
We rented one from a company for a few days and believe it was a 3 or 4k. The engine is the same as what's used in a caterpillar. Since we're moving on from cat and toyota I don't see that as a issue yet.

They are cheap, and the support sucks. I am not a dealer for them, but have had nothing but trouble getting parts, or even correct info on these trucks. the 5k lifts are decent, but the larger trucks are terrible. have a customer with a 50k lift, doosan no longer sells a starter for it and it is like 5 years old or newer.
