TheBirdman,
Let see, I can think of 5 safety related issues when using the forks inverted on the carriage" 1.) the fork locking notches are on the top carriage bar & none on the bottom bar. 2.) Secondly, the fork taper (approx. 1/3 of the length of the fork & greater with FT&P forks) is on the load supporting side - can affect load stability 3.) you will notice that many "quality" forks have an extra thickness of metal at the 90" bend, generally on the back side, so that when a load is on the forks it applies a compression force in this area (this is good). But when the forks is inverted the loading forces want to rip or bend this area not good.4.) since the vertical portion of the forks & carriage bars serve as a load backrest by inverting the forks one has no load backrest therefore the load has a much greater opportunity to fall on the operator 5.) I don't believe you will find one lift truck & or attachment manufacturer that would say it is OK use standard pallet forks in the inverted position - even in case of an "emergency".
