Have you heard of 'Wilmat'. They are made in England. Their walkie trucks operate in the smallest gangways. They are heavy duty and need very little maintenance. They do not have a dealer in your area yet but could be maintained by any good flt repairer.
50% of their production go to other fork truck companies and many are rented out. Wilmat also manufacture trucks for special applications or to meet special conditions. They manufacture trucks from 300kg capacity up to 12.5tonnes, straddle stackers up to 4000kg as well as platform trucks and tow tractors. Put Wilmat into google and look at their website.
