Gotta agree, IMHO Linde do make the best counter balances, we very rarely get a problem with them & the newer machines are laid out well under the bonnet & there pretty easy to work on.

The newer Linde trucks do look like they have been designed with ease of maintenance in mind.

DO you have the Linde Line? If not Why Not?

You are correct NACCO does offer a light duty short cylce 80 volt truck. For the user in light duty operations it will work fine. Heavy duty, hard application, more than 3 hours run time, it won't hold up. Just not their specialty

NMHG (Hyster/Yale) also makes a 80 volt pneumatic.

BleedGreen, is Cat and Clark your only option? Do you also have the Linde line?

If the product is sold and an order not taken,,,and you use a true 80 volt approach then you will be successful. Your service department will be your worst headache and problem (doesn't matter whose 80 volt you sell Linde, Jung,) Most service departments are resistent to doing things a different or new way...Most of them can't tell the difference between a monthly PM and scheduled maintenance...

Sold similar units to the power companies in GA called EMC. Units worked well (biggest complaint - the are too quiet for NASCAR country) - the Linde unit and I assume the unit you sold were set up for working in the rain as standard - sealed this & that's water gutters, etc.
Our EMC's are sort of like electrical power co-ops. They are in the business to promote "buying electricity" over natural gas so they need to practice what the preach - I weaved that thought into to my sales pitch (less direct than stated above of course).
Just make certain your service folks are trained on the units & have more than one set of service software to take care of the units. At the time these units were sold the service department was armed with one laptop load with software & one trained tech - a road tech. This caused some issues as you might imagine.
