We run a lot of Jungheinrich kit both in our rental fleet and customers own. Warehouse kit is the best on the market but can be hard to repair without the diagnostic equipment. We have some reach trucks that have done over 20000 hours and don't give any issues. Controllers can be very expensive as they are propriety items. AC hyd controller for a 3 wheeler is close to £3000GBP!!!! Torque converter IC trucks are good as they run Mitsi running gear but steer clear of hydrostatics they are electronic controlled, hard to repair and un reliable.
