I know for a fact that there is at least one major forklift manufacturer that promotes using their forklift trucks in towing applications.
Those of you that are familiar with the scope of trucks made know that there are walkie tow "tractors" that are only made for towing. Just curious, if you needed to tow a 6,000# load would you feel more comfortable using a small walkie truck that has miniature brakes and weights maybe 1,000# including the battery or be sitting inside of a forklift truck that weighs 8,500#.
I would say that most people in this forum know "weigh" more about forklift trucks than the "fine" people at OSHA. Just ask them if a strobe light and a backup alarm are required on a forklift truck. Their knee jerk reaction will be "of course". I don't think so. Check again
