Posted By David Whaley George, You should check your fork truck specifications this should provide you with the minimum aisle width for operating the truck with a standard load. Failing that you could work it out, if you have reasonably standard load size e.g. pallets, by marking the floor and trying with the truck. Other considerations could be from a risk assessment taking into consideration items like pedestrian access, lighting levels, etc. It's worth bearing in mind that some trucks are designed to operate with virtually no clearance because they employ guidance systems.

Posted By PH Its been a few years since I trained on FLTs but I seem to remember the width of an aisle being determined by the turning circle of the truck. As someone else has mentioned, you need to check the truck manufacturers recommendations. Regards, P
